5 Benefits of Cyber-Physical Systems (CPS) A cyber-physical system summarizes... the benefits of embedded systems the support of a broad range of communication technologies The technical background of CPS enables the acquiring of data of its environment autonomously the decision-making processes over acquired data the autonomous interaction with the environment the autonomous collaboration between CPS in a continuously changing environment the autonomous support of production and logistic processes 5
6 Communication as a Pre-Condition for Collaboration The collaboration between CPS includes e.g. Continuous monitoring of the environment Continuous decision-making processes and corresponding conflict management One pre-condition of collaboration is the communication between CPS CPS must communicate among each other to achieve a complete view over the environment CPS must communicate among each other to react both goal-oriented and collective while a disturbance is occurred To ensure the flexibility and adaptability in the collaboration a corresponding communication approach must satisfy that e.g. Different kinds of CPS can communicate among each others CPS can both connect or disconnect without endanger the stability of the communication medium Communication How can I know which systems need my information? How can I know which systems have my needed information? Which languages will be spoken? Which CPS are currently available? Logistic Unit 1..n Loading Aid 1..n Challenges of a Flexible Communication 6
7 Data Integration Approach for CPS-Based Environments Problem situation The number of systems (including CPS) is increasing in a production environment The communication systems are heterogeneous according to its technical implementation, especially for the data representation The CPS can be used flexible with regard to the role and place of use, which challenges a rigid and hard wired communication medium Objective Researching and implementing of a service-oriented and semantic data integration approach for communication in a cyber-physical environment Communication Partners Semantic Descriptions Transformation Rules Wrapper Components Semantic Mediator Integration Services Logical Views Semantic Mediator 7
8 Data Integration Approach for CPS-Based Environments Results Demonstrator: Semantic Mediator Development of semantic descriptions of relevant data formats for production and logistics environment Development of transformation mechanisms Process model for the generation of logical views Implementation of a service-oriented approach for semantic data integration Communication Partners Semantic Descriptions Transformation Rules Wrapper Components Semantic Mediator Integration Services Logical Views Semantic Mediator 8

12 Linked Resources in Transport Logistics Increase of road transport volume Hardware and software systems to support transport processes for logistics Using of a telematics unit for gathering relevant information of expensive transport units (swap trilors / containers) Reduction of traffic in a global logistics network of approximately 10% 12
13 Containers as Cyber Physical Systems Food quality is sensitive to changes in logistics conditions, e.g. temperature Information gap during transport Changes in the quality are not captured Der Intelligente Container 13
14 Containers as Cyber Physical Systems The Intelligent Container Improvement of the traceability of food by autonomous monitoring of food quality etc. Reduction of food losses by dynamic FEFO in practical applications Development of shelf life models to predict quality changes as function of temperature Prototype implementation and field tests of the intelligent container Der Intelligente Container 14

20 OVERCOMING LIMITATIONS OF LEAN PRODUCTION BY ENHANCED INFORMATION FLOWS Lean Production enables efficient material flow but does not focus on efficient information exchange Industry 4.0 as an overall concept promotes the informatization (computerization) of traditional industries (production / logistics) and focus on an efficient information exchange Approach within the CyProS project: Cyber-Physical Productionsystems Enhancement of productivity and flexibility through networking of intelligent systems in the factory E.g. to assist the application of lean production in complex production environments using Cyber Physical Production Systems 20 BIBA All Rights Reserved.

22 ANALYZING THE AS-IS SITUATION: FACTS AND FINDINGS High variation of number of transported floor rollers in one cycle (from 1 up to 15) Fixed cycle times (every full hour) lead to cycles where the electric train is operated with low capacity. Missing information about the actual status of orders, lead to unnecessary loops for the electric train. Missing information creates waste (conflict with lean principles). Moving from a fixed cycle material supply to a demand driven material supply: The start of a cycle has to be initiated by a demand. 22 BIBA All Rights Reserved. Confidential Document.
