中文摘要：

为了描述协同产品开发过程的复杂性与不确定性，分析了设计主体及组织行为对开发项目的影响，基于复杂适应系统理论建立了设计主体模型；重点研究了设计主体的层次结构，建立了完整的设计主体行为协议，并用谓词逻辑进行了严格的语义定义。将所建立的设计主体模型用于构建产品开发团队多主体仿真系统，给出了仿真系统的程序结构和运算流程；将设计主体模型应用于多主体仿真系统的实例中，证明了模型的正确性和有效性。

英文摘要：

In order to reflect the complexity and uncertainty in collaborative product devetopment and analyse the designs and organization factors during the process,an agent model based on CAS theory was proposed. According to the hierarchy of the intelligent agent, a series of behavior protocols were constructed and strictly defined by predicate logics. Then a multi-agents simulation system which supports evaluation on product development organization were developed. Finally, this system was testified by a simulation experiment.
