机械产品并行设计过程具有多因素、离散、动态和并发等特点 ,尤其是并发性 ,它影响设计结果的稳定性和精度。利用 Petri网良好的离散事件动态表达和计算能力 ,以及图形表示的直观性 ,建立并行设计问题的 Petri网模型 ,并结合应用实例 ,对模型的动态、并发问题进行了分析

Modeling and Analysis of Concurrent Design Based on Petri Net Xu XiaoxiConcurrent design procedure of machinery product possesses multi factors, discreteness, dynamic and concomitant property. Concomitant property influences particularly the stability and precision of design result. This paper makes use of good expression and calculation ability by Petri net in discrete events, and directly graphic property. Petri net model of concurrent design problem is established. And the article analyze dynamic and simultaneous problem of model.design modeling;\ concurrent engineering;\ Ρetri net
