【摘要】 采用基于Petri网的流程建模方法,结合数字化条件下叶片工艺流程设计与评估的相关理论,对叶片制造流程进行重组,并绘制流程框图。利用可达树对Petri网模型进行死锁分析,从而减少流程重组的盲目性和风险。最后通过工程事例说明Petri网模型的死锁分析过程。更多还原

【Abstract】 With combining the theory of blade process flow design and evaluation under the digital condition, the blade manufacturing process is reengineered and the process block diagram is drawn by process modelling based on Petri net. By using the reachability tree, the deadlock of Petri net model is analyzed, and the blindness and risk of process reengineering are reduced. Finally, the deadlock analysis process of Petri net is described through a project case-study.更多还原
