面向主体的协同产品开发过程动态仿真

Agent-oriented dynamic simulation in collaborative production development process

为了研究设计人员在协同产品开发过程中的行为以及过程管理中的典型问题,首先基于复杂适应系统(complex adaptive system,CAS)和多主体系统(multi-agent system,MAS)理论建立了面向主体的协同产品开发过程动态仿真集成模型,该集成模型主要包括4大部分:设计主体,管理主体,环境对象(任务、资源和产品信息)以及动态仿真系统的功能模型.其次,介绍了动态仿真系统的开发方法,并对仿真流程、类的封装及各主要函数的调用过程进行了详细的描述;最后,对某摩托车发动机开发项目进行了仿真实验研究.仿真结果表明,面向主体的动态仿真能为协同产品过程管理提供科学和量化的决策依据,同时,为该过程中人员的行为研究提供了一种新的思路.

In order to study the behaviors of designers in collaborative production development process and the typical problems of process management,an integrated model of agent-oriented dynamic simulation based on CAS and MAS theory was set up firstly.The integrated model included 4 important parts：Designer agents,arbitration agent,environment objectives（task,resource and product information） and function model of the dynamic simulation system.Secondly,simulation system development method was introduced,and simulation process,class packaging,and functions calling process were described in detail.Lastly,the proposed method was applied on some motorcycle engine development project.The simulation results show that agent-oriented simulation can provide scientific and quantized decision basis,simultaneously,provides a new idea for behavior study of designers in the process.
