Research Of Several Issues On Agile SCM Based On Multi Agent

With personality and diversification demands for customers, globalized economy, double-quick rhythm for updating product, impetuosity competition, and the enterprise was faced with more and more pressure. The future competition will be based on time; agility will be a deciding factor for weighing an enterprise's strength. Based on complex and double-changeable markets, multitudinous enterprises adopt Agile Strategy for exceeding other enterprises. The Agile Strategy that became an important research focus for SCM, debased an enterprise's cost and improved a enterprise's flexibility and quick response ability, that was accepted by academic entities and enterprises.Supported by the National High-Tech. R&D Programs for CIMS, "Development and Applications of Networked Manufacturing System for Special Economic Regions in Zhejiang Province" (Grant No. 2002AA414070), we carried out deeper research on the some problems for agile SCM based on multi-agent.In the 1^st part, the background on Agile SCM was summarized; based on collaboration during Agile SCM, some problems that existing SCM was faced with cross-organization and cross-boundaries interoperation, and application integration and so on; propose an based on multi-agent SCM pattern. The corresponding technologies were analyzed.In the 2^nd part, the architecture for Agile SCM based on multi-agent and the key technology are introduced.In the 3^rd part, a flexible layout was emphasized on work workflow for Agile SCM, but tradition work process that were more rigescent, was fit for predefined work process, and not meted the flexible requirement for Agile SCM, we proposed a SCM-oriented and supporting dynamic modeling workflow architecture; Role-droved formalization depiction on workflow; and analyzed the model's reachable performance by theory of CPNWF-nets. Grid environments and multi-agent technology were introduced into the flexibility of workflow management, and the running principium was analyzed.In the 4^th part, the security on workflow task was made a research. Based on tasks, fine granular authorization strategy and running mechanism were applied to resource management and task management. A workflow subtask-level service authorization that covered changing on subtask authorization, proxy mechanism and node-collaboration task management mechanism, was presentedIn the 5^th part, based on shared and distributed resources' network, cross enterprise and organization collaboration came true. For making full use of network resources and cater to userdemands, in the dynamic network environment, how to schedule effectively task became a research hot. QoS-drived and user-centric Schedule strategy for enterprise application was presented. The first, the performance scales that covered trust degree and assuredness degree were defined, and modeled the integrate QoS: Aggregate Utility Ratio; the second, by user demands, the visible interface and two scheduling methods were presented; the last, by visible scheduling for four performance scales and synthesis efficiency, mutual effect between user and scheduling mechanism came true.In the 6th part, after analyzing the promotive effect of GIS upon logistics, problems that logistics -oriented GIS was faced with and the optimization for system performance effect of Agent upon GIS were summed up. MAGIS (based on multi-agent GIS) was presented and optimization mechanism was analyzed.In the 7* part, we analyzed an enterprise's analyzed for SCM, and presented a PCPASCM prototype an example of quoted price system based a PCPASCM..In the 8th part, the main work and contributions in this dissertation were concluded, and the futures were prospected.
