立足于对产品开发过程的微观分析,建立了基于约束网络的产品开发过程模型及其过程约束网络模型、过程动态模型和过程协调模型等扩展子模型。对过程的约束规划、时序关系、流向控制、状态转移、动力学特性以及过程间的交互协调进行了详细的阐述和分析。结果表明,合理的微观过程建模是实现产品开发全过程、全系统、全性能优化的全生命周期设计目标的重要手段。 Based on the microscopic analysis of the product development process, a product development process model based on constraint network and its extended sub-models of process constraint network model, process dynamic model and process coordination model were established. The process of constraint planning, timing, flow control, state transfer, dynamics and interaction between the process of coordination and detailed elaboration and analysis. The results show that reasonable microscopic process modeling is an important means to achieve the whole life cycle design goal of product development, system-wide and full-performance optimization.
