1 THE SYSTEMS ENGINEERING GROUP 1.1 Business Systems Engineering The Systems Engineering Group deals with the analysis, design, use, and control of systems. A system is defined as a coherent whole that contains different actors, objects, and processes of which a number of aspects can be identified such as: 1. people, 2. data, 3. equipment, 4. software, 5. procedures, such as laws, rules and work instructions, 6. materials, 7. energy, 8. physical and/or chemical quantities. The Systems Engineering Group addresses systems in which human and technological aspects dominate, which we call business systems. The focus is on systems that involve public and private business processes within or between public and private organizations. The business systems and the associated business processes are viewed at different levels, ranging from inter-organizational network structures and primary processes to workplaces of individual workers. Both operation and control of the business processes are considered. The research of the Systems Engineering Group contributes to supporting problem owners in engineering their business systems and processes by formulating adequate engineering approaches and developing effective support tools. This is often referred to as business systems engineering. This involves activities that are aimed at improving business systems and processes, including planning, control, and co-ordination processes. Some examples are: luggage handling at an airport, longterm personnel planning for large professional organizations, the (re) organization of a part of a police organization, and the design of a control system of an underground, automated transport system. A system can be divided into subsystems and/or aspect systems by considering a subset of components or a subset of aspects of the system. Such examples are, the human aspects (as in sociology and psychology), the financial aspects (as in economics and accountancy), legal aspects and power structures (as in legal and political sciences), or the information 4 5

and communication technology (as in computer science and electrical engineering). Also subdivision by geography (Amsterdam Airport Schiphol, as a subsystem of worldwide aviation-infrastructure), hierarchical position (the air traffic control as the managing part of the air traffic), or by function (freight transport as a subsystem of total air traffic) is possible. The PhD and graduate projects in the Systems Engineering Group are mainly focused on designing control processes and developing (collaborative) re-engineering approaches. Major research clusters within the group include the application of computer simulation (dynamic modeling) and computer-supported collaborative group work to support systems design and systems engineering. In terms of application domains, the group gives special attention to the opportunities for improving processes through new information and communication technologies in service systems, such as logistic and financial systems. In most cases, students are involved in the research projects. Student projects are design-oriented, i.e., the projects aim to go beyond analysis and evaluation to well-grounded designs for improving the (organizational or inter-organizational, public and/or private) system that is studied. 1.2 Model building, simulation, and animation The Systems Engineering research is aimed at providing new methods and techniques, supported by tools, for complex problem solving in business domains with a strong technical component. The process of mapping and later solving a supposed problem needs a structured way of representing complex systems and for that a number of methods and techniques are used. As in many fields of science and technology model building and simulation play a major role in this process. An advantage of using simulation models is that the effect of possible redesign of organizational or industrial processes can be qualitatively and quantitatively evaluated before the actual implementation of changes, which may require expensive investments, and changes of work patterns. Within the current research projects, the emphasis lies on discrete event simulation. Within the Systems Engineering Group, the major research interests over the past few years have been to research the effectiveness of (libraries of) simulation building blocks, to research the possibilities of using simulation from start to finish in the entire engineering process, to look at the possibilities of object oriented simulation, and to interface simulation models with real components and (information) systems. This research has for instance led to innovative libraries for airport and port modeling, to simulation models that can control a real logistic system with automatic vehicles and docks in real-time, and to several decision support systems that use simulation models as one of their core components and that are fed by real data from databases and ERP systems. In the past, the focus has been on using standard and commercially available simulation tools. Most of the tools are able to produce an animation of the systems in addition to the numerical output of the simulation, which can be used in group sessions and for evaluation. More recently, the research also includes the development of new simulation tools, because the commercially available tools are relatively closed and not easy to integrate into a distributed environment with other tools, databases, and enterprise systems. The tools that are being designed and built within the Systems Engineering research program are envisioned to become a part of larger suites of tools that are being developed in the SSE (Service Systems Engineering) research program. 1.3 Collaboration Engineering The nascent science of collaboration engineering (see chapter 2) frequently employs a Group Decision Room (GDR), in which a collection of methods and computer-supported techniques are used for efficient group deliberation and communication. The GDR is used as a supporting tool in group meetings for operational and strategic decisions in any kind of business process and for (re) designing business processes. The group uses the two fixed GDR facilities in the faculty building, and a mobile facility that can be set-up within an hour at any location. A number of impressions of sessions with the fixed and the mobile GDR facilities are shown in figure 1. Different from the other groups within the faculty, the Group Support Systems (GSS) in the GDR are not only tools to be used in research and external service activities, but the GSS itself is also an object of study. The goal of these studies is to understand the acceptance, adoption, and diffusion of this technology and use this understanding to develop more effective electronic collaboration in terms of facilitation, meeting techniques, and technology. The main areas of interest are described in the next section. ThinkLets The Group Decision Room of the Delft University of Technology is now 6 7

FIGURE 1 IMPRESSIONS OF GROUP DECISION ROOM FACILITIES an organization without the use of a facilitator. Currently, we designed or are in the process of designing such processes for organizations such as: the Rotterdam Port Authority, the Dutch Ministry of Social Affairs and the European Aircraft and Aerospace company EADS. Group support for distributed sessions A relatively new terrain that is currently researched in the Finance Domain, the first steps have been set. Two Master thesis's have been produced in this field. The main thrust was to see if existing and well known SameTime- SamePlace group processes can be designed in such a way that they can also be executed in a distributed fashion. Collaboration with ING (Dutch bank) and Nationale Nederlanden (Dutch insurance company) have been very rewarding in this respect and in the port of Rotterdam a similar trajectory is underway with respect to crisis-response. operative for 10 years. Research in co-operation with Universities in Arizona and Omaha delivered a large set of building blocks that represent techniques to reach a goal with more focus and efficiency. These techniques are gathered and documented in a way that they are repeatable and simple. The ThinkLets, as we call these building blocks, are meant to use in combination with a Group Support System, but can, with some small modifications, be used in combination with more simple tools like post-it and whiteboards as well. More information about this can be found in the Service Systems Engineering programme and at the GDR-website, http://www.gdr.tbm.tudelft.nl. Repeatable Processes Another line of research that we have embarked upon in the past year together with our counterparts in the USA. That is the development of repeatable processes that, ultimately, can be executed by members within Integration of Modelling, Simulation and GroupSupport In the simulation and group support field researchers have converged on a common problem. That is the question whether or not it is possible to improve both process and outcomes of meetings in a multi-actor hightechnology context. Special attention is paid to the question how Simulation (building blocks) and Group Support Systems can be integrated to support large technical projects and organizations more effectively and to the question to wat extent parst of the modeling phases can be executed in distributed way. A collaborative venture with, especially, the University of Brunel (DISC) but ultimately with a network of European Universities has been initiated and the intention is to develop this line of research as a mean to unify the different bodies of knowledge produced at the section of Systems Engineering, within the context of the Service Systems Engineering programme. 1.4 A broad application domain The systems engineering approach is not restricted to a single application domain. This makes it possible to quickly deploy the approach within diverse application areas. Examples are inter-organizational co-ordination in the port of Rotterdam, personnel logistics using simulation models within a major military organization, the dynamic modeling of the administrative workflow in business processes (e.g. at an insurance company), capacity planning within certain organizations, the design of transport chains and the assigning of gates at the airport Schiphol, the exploration of the 8 9

possible role of telematics within organizations, the use of group support systems on governmental policy development. This enumeration, which is far from complete, illustrates the generic character of systems engineering. 1.5 Systems on micro, meso, and macro level A number of different levels of view can be chosen when modeling organizational processes. Individual support engineering on the micro level to support the individual worker in his/her activities that are placed in the network of relations with clients and colleagues, is one level that can be chosen. Another level is that of the intra-organizational engineering, also called the meso level. This level is focused on the behavior of a single organization, which can be viewed as a system that consists of persons and machines. The third level is the level where we look at multiple organizations, called inter-organizational engineering or the macro level. The purpose of this view is to make a joint effort in improving the processes between organizations. For example, consider a network that transports electricity or gas to the end user, or the transport of packages, containers, people or materials, where the bank plays a role with functions such as payments by means of credit card, chip card, bankcard and home-banking. Organizations use systems such as workflow management systems, decision support systems, information systems, co-ordinating systems, and quality control systems to improve the quality of their services. In addition to the services, one often can recognize a certain infrastructure that is used to bring the services or goods from the supplier to the end-user. Examples of infrastructures are road, sea, air and train networks, communication networks with satellites, the electricity infrastructure, and pipeline networks to transport oil or gas. This view abstract the dynamics in networks of organizations, involved in providing services efficiently and effectively. 1.6 Interesting and challenging jobs after graduation Experience has shown that graduates and PhD s of the Systems Engineering Group are able to find exciting and challenging positions. Many work in a consulting position within a consulting firm or a staff position in a large company. The consultancy is focused on general organization, improvement of business processes, information providing, information and communication technology and logistic aspects. 2 RESEARCH 2.1 The specialty of the Systems Engineering Group The society in which we live is becoming increasingly complex and dynamic. Distances lose their meaning. New technologies increase the possibility to do more work in ever less time. Whether it is about production or supplying services, about hospitals, transportation companies, police forces or universities, all of these organizations are looking for ways to achieve their goals more efficiently and effectively within these dynamic surroundings. More often this requires co-operation, where a great diversity of activities has to be tuned across the boundaries of organizations and countries. The increasing dynamics, enabled by transport and information technology, sets higher demands for the capability of an organization to anticipate and respond flexibly on developments. The Systems Engineering Group focuses on the subject of designing efficient information intensive network organizations, that work dispersed in time and location. The search for ways to improve the quality and efficiency of the performance of (groups of) people by means of better co-ordination, structuring and improved support in the working space is one of the key issues. In practice this requires the integration of technical, organizational, communicative, informational, and decision-making aspects in an actual design of a system. The group makes a contribution both to the development of theory and of practice by developing and empirically validating models, methods and tools used in interdisciplinary analysis and design of administrative, information intense processes and systems. 2.2 The research profile of the Systems Engineering Group The Systems Engineering Group carries out research on complex processes within and between organizations. The problems connected to those processes are approached from a collaborative systems engineering point of view. The field of research of the group can be structured into domains, tools or support environments and theory development and methodology as illustrated in the overview of figure 2. 10 11

The Systems Engineering Group carries out research in the program Service Systems Engineering that depart from the need for innovation of business processes, especially networked business. The main focus of the research activities in the area of Service Systems Engineering is on designing, developing, and evaluating services and service processes. For example, this may involve the engineering of organizational processes that have to create a service for the organization s clients or the evaluation of co-ordination mechanisms for channel management in Electronic Commerce situations. collaborative systems engineering MICRO 2.4 Activities in 2003 THEORY DEVELOPMENT METHODOLOGIES The Systems Engineering group organized the following conferences and workshops. Application domains The domains refer to reality. A large part of the research can be placed within the three application domains that are distinguished within the Systems Engineering, Policy Analysis and Management education. A number of research projects connect different domains, for example: traffic telematics where systems engineering research is performed on the boundaries of ICT and Transport and Logistics. Support environments The support environments refer to the tools that support the complex problem solving process. Within the Systems Engineering Group, the main focus has been on simulation and animation and on Group Support Systems (GSS). Recently, more attention has been paid to tools for component libraries and building blocks as well. Theory development and methodology Within theory development, the starting point is the inductive hypothetical model cycle, in which the use of models and a problem solving view are the key. 2003 May Organized a one-day workshop IT Architectures and Architecting. More than 30 leading researchers and experts from industry and academia took part in this symposium. Five presentations (one US and four national) gave an opportunity to valuable discussions on the research directions of this important area. 2003 May Organized a two day BETADE - DIOC workshop at Noordwijkerhout, where 14 junior PhD researchers across TU Delft faculties presented their work and discussed many research issues with a panel of experts and with their promoters and supervisors. 2003 October Hosted the 7th IEEE conference on Distributed Simulation and Real-Time Applications (D-RT 2003). Around 40 researchers joined this specialized workshop, which was for the first time held outside USA. 2003 October Did the organization of the local 15th European simulation symposium, where more than 100 researchers met for a three day scientific conference. 12 13

These projects can be placed in the framework of figure 2, both in support environment and application domain parts. Containers op dreef Containers op dreef (Containers adrift) is a simulation game in which various stakeholders, played by the participants, plan and design an inland container terminal in a designated search area in the provincial town Maaswijk. The participants apply principles of decision-making process design and management. The making and evaluation of the terminal design is supported with a design tool based on discrete event simulation. The aim of the game is to learn participants about interaction between systems design and modeling, and decision-making in situations with diverging stakeholder interests. Main researchers: dr.ir.wieke Bockstael-Blok, dr. Igor Mayer (Delft University of Technology), and Edwin Valentin The design and process goals for payment transactions system across borders The banking industry, along with nearly every other industry, has become increasingly global over the past decade. As businesses of all sorts discover the need to address a global market, this globalization is reflected in the banking services. Bank customers have also become increasingly demanding regarding the speed and accessibility of services. Competitiveness in the banking market now depends less upon regional expertise and more 14 15

on global information management and customer service. This research aims to determine methods for globalization of specific banking services. Each financial institution wishes to expand its services to be more accessible to global and individual clients, for example, through facilitating financial transactions across national borders. Two of the central problems in this expansion are the dispersal of client account information among different national networks and the different procedures for performing transactions in different countries. Increased centralization of information and procedures would result in a mutually beneficial improvement in bankcustomer relations, providing improved services for the customer and improved information access for the bank s management. This research identifies the obstacles to increased globalization, such as differences in national tax codes, and examines ways of handling these obstacles in the globalization of transaction processes. Main researcher: Ir. Nadia Ayad Supporting Adaptive and Robust Airport Master Planning and Design in an Uncertain Environment In the era of deregulation and globalization strategic airport master planning increasingly needs to deal with uncertainties and dynamics of changes in the aviation industry outside of the control of airports. Traditional airport master planning methods don t deal very well with uncertainties and risks - in general, one forecast is prepared for the most likely future extrapolating the past traffic development. Thus, the master plan design and the investment plan is based on one single view of the future that, as several examples have shown, unlikely becomes true. A master plan prepared in this way is rigid and involves the following problems: first it does not consider uncertainties and risks of changes if future unfolds different than forecasted, second it does not include flexibility, adaptability and robustness in the design, and thus third it carries a high risk of not being economically and functionally efficient. There is a clear need for an alternative master planning approach that considers uncertainties and risks in a proactive way and introduces flexibility into a dynamic planning and design process catering capacity and structural requirements of not the most likely future but of different possible futures. The challenge is to support airports in exploring strategies and concepts for airport designs that are robust, flexible and adaptive enough to respond to multiple potential futures. The objective of this research project is to develop a framework of integrated tools that supports airports in preparing robust airport master plans that respond to multiple potential futures. Main researcher: Dipl.-Ing. Uta Kohse An Organizational Decision Support System for Airport Strategic Exploration The Delft Airport Development Center started a research project in 2002, which deals with the development of an airport planning and decision support tool, named Airport Business Suite. The Airport Business Suite aims to answer strategic what-if-questions about the range and the possibilities of future airport development to handle future traffic demand showing the consequences on revenues and investments when applying certain policies. It is a tool that produces scenarios from a range of parameters allowing the comparison of output from different scenarios for strategic exploration. The system is a software tool that integrates several models from forecasting flight schedules and capacity analysis of airport facilities, calculating the requirements for additional airport infrastructure up to the estimation of investments to revenues in airport improvement and expansion. In 2003, prototype of the system had been finished and represented. Main researchers (from the Systems Engineering Group): Dipl.-Ing. Uta Kohse, ir. Zoran Stojanovic Geodan Holding b.v. Amsterdam The main aim of the project is to incorporate in the next version of the P-Info system, the concepts and principles of model-driven componentbased and service-based development, in order to benefit from these novel development paradigms. Furthermore, an appropriate development process for Geodan should be proposed. Main researcher: ir. Zoran Stojanovic Various meetings in the Group Decision Room (GDR) At the request of various (international) organizations and institutions, about fifty meetings were prepared and facilitated in the GDR. These projects with a short life span were aimed at facilitating a particular activity or phase from the problem solving process that the organizations were going through. Execution: dr.ir. Gert-Jan de Vreede, ir. Rachid Maghnouji, ir. Jaco Appelman, dr.ir. Mariëlle den Hengst, drs.ing. Jürgen van Grinsven Supporting intra-organizational distributed co-ordination The central theme of our study is to find out how organizations can improve the co-ordination between distributed groups and actors within an already existing organizational context. This research contrbuted to the CSCW field and delivers solutions for the problems that arise in distributed co-ordination because of the complex interaction between organisational, 16 17

behavioural and technical factors. We aim to provide for an integral framework that enables us to guide co-ordination improvements (instead of only describing them). In 1998 we entered the Amsterdam Police Force and described the intra organizational co-ordination problems as part of our inductive research strategy. In 1999 a simulation game has been developed to enable police officers of the Amsterdam Police Force to experience the benefits as well as drawbacks of new ways of co-ordinating. During the second half of 2000 and in 2001 the framework and the game approach have been applied to another collaboration process where dispersed groups and actors have to co-ordinate their actions. The research findings resulted in a dissertation in 2003. Main researcher: ir. Joeri van Laere Design approach for Mobile Information Services This thesis research project is concerned with the development of a design approach for mobile information services. Telecommunications, media and IT companies leverage the flexibility of digital technology to offer services that go beyond their traditional sectors and target markets. The blurring boundaries between telecommunications, IT and media industries are further overcome by the emergence of new players leveraging the full potential of the Internet to deliver content, access and services. Mobile Information Services are an exponent of this development. The objective of this research is to develop and test a service system engineering approach for mobile information services in an inter-organizational setting. The focus is on the network formation and co-ordination on the supply side. In 2002 the researcher participated in a project of the Telematica Instituut: BITA (Business Models for Innovative Telematics Applications). Results of the case studies done by the researcher are incorporated in this PhD project. Main researcher: drs. Els van de Kar The use of simulation in the design and realisation process of automated container terminals In order to meet the demands from today s customers, container terminals have to increase their productivity with a significant rate. Besides, they are confronted with ever-increasing wages. Therefore in all new container terminal development projects robotisation of operations is considered as a serious option to cope with both demands: higher productivity and lower cost. Simply increasing equipment performance or putting in more equipment will not accomplish higher productivity at a lower cost. It requires rethinking of the entire terminal concept. When designing a robotised terminal an integrated design approach is required, combining hardware (equipment) and software design. Furthermore it should integrate the different design tasks such as functional design, technical design and realisation. A key element in a robotised terminal is the process control system, which controls and co-ordinates all functions in the terminal. Especially the design of this real-time planning and control system requires serious attention. The approach needs supporting tools that address the specific characteristics of processes at a container terminal - high impact of external influences, high degree of uncertainty, many disturbances - and are able to provide this support throughout all design activities, including realisation. A design-supporting tool that has proven to be applicable for that is an environment of various simulation models. Simulation is used to support the entire design process, especially focussing on the interaction between hardware and software. Within the simulation environment prototypes of the real production software are developed and production software is tested using the simulation environment. The design approach and support environment have been applied in a number of real-life cases and have shown to improve insight for all people involved including technical and managerial staff. It also provided early support for equipment design and software testing. Main researcher: ir. Yvo Saanen Satisfaction in problem solving meetings In 2002/2003 a causal model (theory) was developed describing what makes participants satisfied in creative problem solving meetings. Based on this model, a satisfaction questionnaire was designed that could be filled in by meeting participants after a meeting. In 2002/2003, this model has been validated by collecting over 230 questionnaires from the Netherlands. Current research efforts focus on collecting more data in different socio-cultural environments and using the theory to explain conflicting experimental GSS research results. Main researchers: dr.ir. Gert-Jan de Vreede, dr. Robert Briggs (University of Arizona & Delft University of Technology), dr. Bruce Reinig (San Diego State University) thinklets: Building blocks for collaboration engineering Over the past decade, Group Support Systems (GSS) has shown that, under certain circumstances, teams using GSS can be far more productive than teams who do not use GSS. However, research results are not unequivocal; they have been ambiguous, and sometimes conflicting, which makes it difficult for GSS research to inform GSS practice. One cause of the conflict and ambiguity in GSS research results may be the result of focusing 18 19

on a less-than-useful level of abstraction: GSS itself. In this research project, the thinklet concept is introduced as a more useful unit of comparison than the GSS. A thinklet encapsulates three components of a GSS stimulus: The tool, its configuration, and the script. Field experience shows that thinklets may be used to create repeatable, predictable patterns of thinking among people making an effort toward a goal. To date about 50 thinklets have been documented that map to five basic patterns of thinking: Diverge, Converge, Organize, Evaluate, and Build Consensus. Each thinklet creates some unique variation on its basic pattern. ThinkLets will provide the building blocks for facilitators to prepare and moderate concerted collaborative efforts. The use of thinklets to support the design of collaborative processes is investigated in a number of ways: - Through action research studies on collaboration engineering, among which First National Bank, the Lewis and Clark project, STATPack (part of Nebraska Research Initiative), and the ING Group. - Through case studies on self-sustaining GSS communities, with the Rotterdam Port Authority and the Dutch Ministry of Foreign Affairs. - Through the development of a description of collaboration engineering as a design methodology. Main researchers: dr.ir. Gert-Jan de Vreede, dr. Robert O. Briggs, drs.ing. Jürgen van Grinsven, dr. Ann Fruhling (University of Nebraska at Omaha) Distributed simulation of Truck Service Centers for the 2nd Maasvlakte In 2003, a new study was conducted for the Port of Rotterdam within the FAMAS Maasvlakte 2 research program for Connekt/TRAIL. In this study, distributed simulations have been developed to model the container truck transport for the future extensions of the Port of Rotterdam. The distributed simulation environment combines several independent models using distributed modeling techniques. This entails a truck generator, a simulation model of the road system, a detailed simulation model of the terminal, and the application of an agent based planning and scheduling model. The communication between the models is orchestrated by the so-called FAMAS Backbone infrastructure, which has been developed in an earlier FAMAS Maasvlakte 2 project. A number of joint experiments have been carried out to test the XML/SOAP communication between the agent-based planning system, and to test several planning strategies. Researchers: dr.ir.alexander Verbraeck, ir.yvo Saanen (TU Delft / TBA), Csaba Boer (EUR), and several external researchers Supply Chain Simulation Libraries In co-operation with the Robert H. Smith School of the University of Maryland and other partners of the Global Technology and Management Consortium (GTMC), a number of building-block libraries have been developed in several simulation languages to support real-time supply chain education and gaming. Using these libraries, a number of MSc students developed several demonstration cases and training cases where students can experiment with the simulation models to determine a good supply chain strategy. Simulation languages that were used to develop the libraries are Arena, em-plant, and D-SOL. Researchers: dr.ir. Alexander Verbraeck, ing. Edwin Valentin, ir. Peter Jacobs, ir. Stijn-Pieter van Houten D-SOL - A Distributed Simulation Object Library in JAVA When using discrete event simulation in a distributed setting where interfaces with real-time information systems are needed, almost no simulation environments are available that support this real-time and distributed character well. Currently, many of the attempts to reach these types of distributed simulation environments are based on a process-oriented, and therefore multi-threaded paradigm. This results in simulation environments that are very hard to distribute over more computers, and not easy to integrate with scattered external information sources. The D-SOL architecture is based on the event-based paradigm which is implemented by scheduled method invocation. Objects used in the simulation environment interact with remote, a-synchronous subscribed clients (e.g. a web browser) in order to produce representations of the (simulated) system. The environment, which is implemented in Java, consists of a simulation and representation library and it is integrated with several statistical libraries. Researchers: ir. Peter Jacobs, ir. Niels Lang, dr.ir. Alexander Verbraeck Congestion-Free Vehicle Routing The congestion-free vehicle routing project for AGVs was carried out for ECT in the Port of Rotterdam in co-operation with TBA. The main result of the project was a unique and fast route scheduling algorithm that can guarantee a route execution without any hindering of other vehicles. As a result, all vehicles drive with their maximum speed and do not have to brake or stop along the route. We reckon this as a major step forward in comparison with normal traffic of the automated transportation system zat the container terminal. Without reliable transportation times it is extremely difficult to schedule operations on the terminal for the planning and control system. Besides the complexities inherent to the terminal 20 21

operation, the challenge for the route-scheduling algorithm was execution speed, because it has to be used in real-time operation, and in a simulated environment that was running 10-20 times faster than reality. In the project, all these goals have been met. Researchers: dr.ir. Alexander Verbraeck, ir. Yvo Saanen (TU Delft/TBA) LOGIS - Leonardo Project for Logistic Simulation Education In 2001-2002 the LOGIS project for the EU has been carried out with the TU Riga in Latvia and other partners on educational material for Logistic Information Systems, especially in port environments. The project has resulted in several deliverables, among which teaching material and a book chapter on simulation. Main researchers: dr.ir. Mariëlle den Hengst, dr.ir. Alexander Verbraeck The Effect of Visualized Summarization to Collaboration One important way a facilitator can add value to a group meeting is to summarize the discussion. Visualization offers a promising way to show meaningful relationships in information. The effect of visualized summarization on the divergence phase in group supported meetings is still largely unexplored. We developed a research model to measure the effect of visualized summarization. Experiments have been carried to measure the effect of visualized summarization. Main researchers: dr.ir. Mariëlle den Hengst, Mick Mcquaid (University of Arizona) Supporting Decision Making in the Methanol Production Chain We have executed a study that explored a variety of carbon-based feedstocks such as natural gas, oil, coal, organic waste streams, and renewable resources (biomass) for the production of methanol, in order to find and demonstrate the potential of new, sustainable methanol production chains. We modeled the methanol production chain as an assembly of various independent operations, and we have automated the process of assembling and adjusting the methanol chains. We screened and compared various methanol production chains with respect to key performance indicators and their sensitivity towards various future environmental and economic policies. Experiments have shown that straightforward modeling of processing chains can contribute significantly to decision making in the methanol chain. Main researchers: dr.ir. Mariëlle den Hengst, dr.ir. Paulien Herder (Delft University of Technology) Design approach for Mobile Information Services This thesis research project is concerned with the development of a design approach for mobile information services. Telecommunications, media and IT companies leverage the flexibility of digital technology to offer services that go beyond their traditional sectors and target markets. The blurring boundaries between telecommunications, IT and media industries are further overcome by the emergence of new players leveraging the full potential of the Internet to deliver content, access and services. Mobile Information Services are an exponent of this development. The objective of this research is to develop and test a service system engineering approach for mobile information services in an inter-organizational setting. The focus is on the network formation and co-ordination on the supply side. In 2003 Els led an action research project testing the design approach by building a mobile service for campus visitors on the UMTS testbed at TU Delft. The UMTS testbed was provided by T-Mobile. In this project TU Delft is the innovator that developed and launched a Mobile Information and Entertainment Service in an inter-organizational setting having passed through a complete predetermined design approach.

Els van de Kar UMTS: User Requirements Elicitation with GSS The main challenge in the first phase of designing mobile services is eliciting user requirements. We propose a repeatable process for eliciting user requirements based on the literature on requirements engineering and group support systems. We applied the repeatable process in three sessions to elicit user requirements for a mobile information service on a UMTS testbed. The sessions resulted in ideas for services that are highly valued by potential users and criteria for when they will of will not use the service. Main researchers: dr.ir. Mariëlle den Hengst, drs. E.A.M. van de Kar, drs. J.H. Appelman Collaborative Conceptual Modeling Conceptual modeling of business processes is used on a large scale to facilitate for instance Business Process Reengineering, ERP system implementation, Total Quality Management, Workflow Management, Knowledge Management, E-business. Modeling is increasingly collaborative (for understanding, buy-in, complexity). Models are used for communication. Collaborative modeling is difficult- one of the reasons is that non-modeling experts have to use the technique. The overall goal of our research is to identify properties a conceptual modeling technique should have to be used by non-modeling experts. Main researcher: dr.ir. Marielle den Hengst 22 23

EduHbo - Curriculum Logistics Simulation In a co-operation with the Open University in Heerlen, a simulation library has been developed to model the logistics of students and teachers within an educational organization. The first application of the library has been to study the effects on throughput times of students and capacity use of teachers when the educational program is changed into a totally flexible and demand driven curriculum. The D-SOL simulation environment that has been developed by the Systems Engineering section was used to develop the library and the simulation models. As a result, the models could be easily demonstrated without installing any additional software, and could be even shown to the educational institutions from a Web browser. In 2004, the research results will be published in the dissertation of Ad Schellekens from the Open University. Researchers: dr.ir. Alexander Verbraeck, Ad Schellekens (Open University Heerlen) the world, the newest strategies in these fields have been introduced to specialists from US-STRATCOM, Northrop Grumman, and Lockheed Martin. Delft Researchers: dr.ir. Alexander, Verbraeck, prof.dr. Peter Keen Park-A-Car Fully automated transportation systems have been researched in several projects by the Systems Engineering section in the past. FROG Navigation Systems is one of the most innovative companies in this field, and it is currently researching the application of automated parking garages using automated guided vehicles. The advantage is that no room needs to be reserved for walking passengers or around human-driven cars. Compared to a normal parking, an automated parking can store considerably more cars. The logistic control, however, is quite difficult, because the arrival and departure patterns of the cars are not divided evenly over the day. There are steep peaks in the patterns, that demand strategies like prefetching and intelligent location allocation of the cars. A D-SOL simulation library has been developed to study the effect of various allocation and control algorithms for a proposed parking garage in Rotterdam. Researchers: dr.ir. Alexander Verbraeck, ir.

PETER KEEN has served on the faculties of Harvard, MIT, and Stanford, with visiting positions at Wharton, Oxford, Fordham, the London Business School, Stockholm University, and Duke University. In 1994, he was profiled by Forbes magazine as the consultant from Paradise. In 1988, he was named by Information Week as one of the top ten consultants in the information technology field. His research, writing, education and public speaking all focus on helping firms make a management difference in their deployment of information technology as a business resource and on bridging the gap in understanding, language and planning between business decisions and technology choices. When all leading firms in an industry have access to the same technology, the competitive edge comes from fusing people, process and technology. The management challenge is for business managers to lead IT, without having to know the details of the technology but understanding and enacting the key decisions about policy, infrastructures and funding that enable their technical professionals to design, implement and operate the platform. That integrated platform is an essential base for business innovation in just about every industry today and vital for co-ordinating operations in a global environment. A prolific writer, Peter Keen is the author of many books that have strongly influenced the business-technology dialogue, starting with Decision Support Systems (1978), that introduced in the early 1970s the concept of IT as a support to managerial judgment, Competing in Time: Using Telecommunications for Competitive Advantage (1986), the first book to anticipate the immense impact of telecommunications on the basics of business, and Shaping the Future: Business Design Through Information Technology (1991), a book addressed to senior executives that has been translated into many European and Asian languages. The Process Edge: Creating Value Where It Counts (1997) looks at business processes as invisible financial assets and liabilities to be managed as a portfolio of capital investments targeted at increasing shareholder value. His most recent books all address the management side of electronic commerce and the Internet Economy. The e-process Edge (2000) focuses on sourcing process capabilities and From.Dot to.profit (2000) zeros in on the value imperatives that drive effective business models. Earlier books are Trust By Design (1999), Business Internets and Intranets, and On-Line Profits. He has worked as a consultant on a long-term basis as an adviser to top managers in helping them fuse business choices and technology decisions. Examples of companies with which Keen has worked in this mode include: British Airways, British Telecom, Citibank, Glaxo, IBM, MCI Communications, Royal Bank Of Canada, Cemex (Mexico), Sweden Post, Unilever, World Bank, IATA, CTC (Chile), HP and many others. His work with these companies has generally included the development and delivery of senior management education programs for action (rather than just awareness ) as a lever for taking charge of change and making IT part of everyday planning and management thinking. He is on the Advisory Boards and Boards of Directors of several Internet companies including e-credit, WebIQ, Xybernaut and Celosis. 32 33
