并行工程管理系统是并行工程的核心，它由产品开发过程建模仿真与优化子系统和产品开发过程管理与协调子系统组成。本文讨论了用于产品开发过程建模的ＩＤＥＦ３过程描述获取方法，提出了系统的体系结构和主要功能，建立了面向对象的产品开发过程仿真机制。
Parallel engineering management system is the core of parallel engineering. It consists of product development process simulation and optimization subsystem and product development process management and coordination subsystem. In this paper, IDEF3 process description acquisition method for product development process modeling is discussed, the system architecture and main functions are proposed, and the object-oriented simulation mechanism of product development process is established.
