摘　　要：将随机网络技术应用于并行产品开发过程建模。阐述了并行产品开发过程中的信息预发布模型与并行度定义,提出支持并行产品开发的随机网络计划方法,进一步给出对随机网络计划进行仿真计算的方法。在定义产品开发并行活动间的并行度、时间重叠度和信息耦合度等特征值的基础上,对并行产品开发整个过程的并行度进行量化计算,并以产品开发实例应用说明了该方法的有效性。Stochastic network technology was applied in concurrent product development process modeling. The in formation prerelease model and the degree of concurrence definition were presented, and the stochastic network planning method was put forward to support concurrent product development. Thus, the corresponding simulation method was proposed. Based on the definition of eigenvalue, such as degree of concurrence, degree of time overlapping and degree of information coupling, the degree of concurrence of the whole product development process could be calculated accordingly. An example of product development process calculation was provided to illustrate the va lidity of this method.
