Background - Product Lifecycle Management (PLM) Managing the entire lifecycle of a product from its conception, through design and manufacture, to service and disposal Wikipedia Slide 6 PLM
Why Architecting - why modeling? Products Business processes (WIP) Create/change processes Rework (MRB,... ) Machines / Workcenters Tools, Gauges Fixtures Heat Treatment procedures NDT Robots Quality standards (AS9100C)... SAP - Enterprise Resource Planning DMS Teamcenter (PDM / PLM application) OpPlan - Legacy Operational database NX6.05 (CAD) SolidWorks (CAD) AutoCAD (CAD) Vericut (NC simulation) NC program library Calypso (CMM) Quindos (CMM)... Slide 7 Systems of PLM
Four Traditional Methods of Architecting: Normative Hard rules are provided, success is defined by following the rules Participative Solution from group process / group consensus Rational Solutions derived from objectives Heuristics Develop solutions from lessons learned (guidelines, rules of thumb,...) In practice, successful architecting is a mixture of rational and heuristic methods, with some participative and normative used in particular situations Mark W. Maier Slide 8 Methods of Architecting
Model organization Six-View Modeling Slide 9 Model organization
Two opposite approaches to modeling The Bottom-Up approach Methodologies Data Mission Roles Products Databases People Processes Workflows Cost Strategy Budget Objects Threats Value Chains Stakeholders Objectives Risks Requirements Values Models Information Applications Constraints Machines The Top-Down approach A Model is an abstraction of Reality Raw Materials Products Slide 10 Bottom-Up vs. To-down
The Top-Down approach Taguchi: Signal Factors (M) Noise Factors (x) Respons (y) Selected view and level of abstraction depends on the "viewpoint" Control Factors (z) Burlton's IGOE: Slide 11 The Top-Down Approach
"Viewpoint": Product Lifecycle Management Raw Materials Products Three domains: System Architecture Manufacturing Enterprise Resource Planning (ERP) PLM Virtual Manufacturing Slide 12 Domains
Characteristics of the System Domains Manufacturing ERP Virtual Manufacturing Production issues Physical and electronical Real world Stochastic variations Administrative issues Electronical Commercial Stochastic variations Technical issues Electronical Ideal world No stochastic variations Slide 13 PLM System Architecture
System Architecture - System of Systems QDAS Calypso Quindos MES Manufacturing VBH ProMark Rektron Jærtech CSup ERP (SAP) DMS TeamCenter NX Virtual Manufacturing Calypso Vericut Software in Manufacturing should be selected based on functionality - not their "affinity" to SAP Preferred system elements in manufacturing have high internal complexity and low external complexity (high cohesion and low coupling) Slide 14 PLM System Architecture
Heuristics: Datastructures Examples: Materials, BOMs, Processes, WorkCenters, Machines, People, Organization,... Manufacturing ERP Virtual Manufacturing The ERP system (SAP) should define the structures and export them to the other domains Slide 15 Datastructures
Heuristics: Information flow Manufacturing ERP (SAP) DMS Virtual Manufacturing (VM) In order to control the information flow, let it flow through the ERP system Slide 16 Information flow
Information flow & "Mapping" Manufacturing Domain ERP / DMS Virtual Domain The ERP/DMS system maps information from the virtual domain to the manufacturing domain, and vice versa. Slide 17 Mapping of information
Information flow: Change Operation Manufacturing ERP Virtual Domain MaterialAdm 3D models 2D drawings Process-structure Process-structure Operation Order DMS Operation Documents Slide 18 Information flow: Change Operation
Process: "Change Operation for pre-production" Manufacturing ERP Virtual Domain Start change process New Change Number New revision in TcM Make changes in TcM Run the operation Update order in SAP Release for pre-produksjon NO OK? YES Process: Release for produksjon Slide 19 "Change Operation"
AS9100C - Process Approach 0.2 Process Approach This International Standard promotes the adoption of a process approach when developing, implementing and improving the effectiveness of a qualilty management system, to enhance customer satisfaction by meeting customer requirements What is a process? One or more activities in sequence Have a defined customer Uses resources in the organization Tranforms "inputs" to "outputs" "Outputs" from one process is often "inputs" to other processes A process can be integrated in other processes Slide 20 AS9100C
OMS - Operational Management System Slide 21 OMS
Process based navigation Difficult to navigate Unclear structure for users Difficult to integrate or connect processes Varying levels of abstraction... Slide 22 Process based navigation
Object based navigation An alternative to Process based navigation Identifies objects in the manufacturing system Assumes that each object has Attributes describing the object Methods associated with the object (create, change,...) iphones, ipads,... use object based navigation! Slide 23 Object based navigation
