摘要/Abstract

摘要： 为满足分布异构环境对产品协同设计的要求，提出了一种基于多Agent的产品模块化协同设计策略。分析了协同设计需求与功能的映射关系，构建了基于多Agent的产品模块化协同设计自顶向下的四层过程模型；从模块内聚度、模块耦合度和模块可执行度三个方面进行探讨，建立了基于多目标优化的模块分解数学模型，利用模块分解Agent实现最优模块划分，通过相似度算法获得求解模块的最匹配Agent；引入集成推理与决策机制构建了协同设计Agent行为模型，给出了基于黑板的Agent平行协商机制。最后，开发了基于浏览器/服务器的汽车协同设计原型系统，并以车身协同设计为例验证了该策略的可行性和有效性。

Abstract: To meet requirements of Product Collaborative Design(PCD)in distributed heterogeneous environment, collaborative design strategy of product modularity based on multi-Agent was proposed. Firstly, PCD top-down 4-tier process model based on multi-Agent was constructed after analyzing mapping relationships between requirements and functions in collaborative design. Secondly, multi-objective optimization mathematic model of decomposition-based modularity was established from perspectives of module cohesion degree, module coupling degree and module executable degree. Optimal modules were obtained by modularity decomposition Agent, and similarity algorithm was used to search the best matching Agents to solve modules. Finally, integrated reasoning and decision-making mechanism were introduced to set up behavioral model of collaborative design Agent. Parallel consultation mechanisms for Agents based on blackboard was given. On this basis, Browser/Server(B/S)based system for automobile collaborative design was developed, and the feasibility and efficiency of this strategy were proved in an example of collaborative design of automobile bodies.
