Allocation Mechanism Study Of Mas-based Collaborative Design Task

With the further application of computer network technology in product development design process, networking products collaborative design technology has become a hot in modern product design theory and method research. Networking product design is multidisciplinary collaborative group personnel solute its field problems in distributed heterogeneous network environment, for a same design goal. In product collaborative design process, design task decomposition, distribution and scheduling problem is one of the core research problems to realize network product collaborative design process control and management.This issue mainly researches the task allocation problem in product collaborative design process; the main work is as follows:(1)On the analysis of the collaborative design task management and distribution mechanism, proposes a collaborative design task allocation model based on MAS of contract nets. Transforms collaborative design task allocation to Agents negotiation. Gives the related task Agent formalization describing.(2)Aims at delay in current contract nets mechanism, proposes a collaborative design task allocation mechanism based on extend contract nets by introducing time token and buffer pool strategy. Gives negotiating tactics and comprehensive multi-factor decision-making evaluating algorithms in the process of cooperation based on bidding information.(3) Develops a task allocation system based on MAS collaborative design task allocation model, which is suitable to engine lathe collaborative design process management. Based on JAVA, SQL achieves functions such as in user management, project management, assignments and other functions. Takes component model for example to test, proves its feasibility of the system.
