11. E-manufacturing: definition “E-manufacturing is a system methodology that enables the manufacturing operations to successfully integrate with functional objectives of an enterprise through the use of Internet, tether-free (i.e. wireless, web etc.) and predictive technologies” -Koc M, Ni J, Lee J.

12. Direction for e-manufacturing Four competencies (design, operate, maintain and synchronize) are required for any manufacturer to be a world class manufacturing company. -Rockwell automation e-manufacturing industry road map • Development of intelligent agents • Development of remote distributed and web-based quality contol systems and their integration with intelligent predictive agent • Development of a dependable and scalable information pipeline/platform • Development of virtual design platform for collaboration

19. DMPDP* Problem(1) • DMPDP Characteristics • Frequent change inevitability • Tightly coupled development process • Disciplinary self-interestedness • Information/control distribution • Component part orientation • Planning and control of DMPDP • Planning  initial scheduling • Control  short-term rescheduling or adaptation • Objective of the paper • Modeling a resource allocation economy including the definitions of goods, producers, and consumers • Modeling an utility function that incorporates the relative values of a good from individual project perspective • Modeling a market protocol consisting of an auction mechanism and bidding policies DMPDP: Distributed multiple product development project

20. DMPDP* Problem(2) DMPDP: Distributed multiple product development project

21. Definitions and notations • Product development project Pi = <Gi, Ci, Qi, Ni> • Gi: set of milestone, Ci: set of all component Qi: set of process Ni: set of precedence constraints • Functional Division Dj is an organizational unit that comprises a set of resources • DMPDP environment π = <P, D> • Deviation cost function Φi:R:R representing the penalty cost due to the deviation of the project completion time from the original completion target Gi1 • Engagement eil = (j, k, l) defines the assignment task Til in Pi to a resource Rjk • Ai: Project plan of Pi is a set of engagement which covers all task in Pi • i.e. Ai = {ei1, …, ein} • DMPDP plan (A) is a set of project plans within the DMPDP planning horizon • i.e. A = {Ai} • Feasible: satisfies all the constraints of both type precedence and resource • Efficient DMPDP plan is Pareto optimal, meaning that no project can improve its utility without worsening the utility of any other project in th DMPDP • Deviation cost range (DCR): max{Deviation cost} – min{Deviation cost} • by definition of deviation cost function • τ-balanced DMPDP plan is an efiicient DMPDP plan that the DCR of individual projects in a DMPDP plan is less than a given tolerance τ

22. Multiagent based IS* model • Project Manager (PM) • Component Agent (CA) • Task Agent (TA) • Resource Manager (RM) • Resource Agent (RA) • Aggregate task vs. Assignable task • Resource time-slot market • Every RA will be an auctioneer for selling the bundles of resource time slots to Tas – the bidders IS: Information System

27. 정 리 • E-manufacturing이라는 이름으로 다양한 연구가 수행되고 있다. • E-manufacturing에 대한 표준적인 정의는 존재하지 않는다. • 넓은 의미에서 e-manufacturing은 생산 전반을 아우르는 개념으로 사용된다.
