基于Petri网的高速铁路综合维修作业调度系统的研究

Research on Comprehensive Maintenance Scheduling System Based Petri Net for High-speed Railway

综合维修是高速铁路维修模式的发展方向。高速铁路综合维修作业调度系统基于Petri网建模,通过分析工作流网的活性和有界性,验证了建模的可靠性,提出建模的实现算法,给出综合维修作业调度系统总体结构设计。实际测试表明,系统符合高速铁路综合维修的需求。

Comprehensive maintenance is the development direction of high speed railway maintenance mode. A comprehensive maintenance job dispatch system for high-speed railway is built based on a Petrinet model. Through analyzing the liveness and boundedness of the workflow net the reliability of the modeling is validated, the arithmetic of model is also put forward, and the architecture of comprehensive maintenance job dispatch system is brought forward. It is shown via actual test that the system meet the demand of comprehensive maintenance for high-speed railway.
