Petri Modeling of Locomotive Overhauling Process Based on Workflows

摘要

The locomotive overhauling condition decides the locomotive utilization safe. In order to carry on the process controlling to the locomotive overhauling, enhances the quality of locomotive overhauling, we developed the software system that carries on the real-time control to the locomotive overhauling process. This paper melts workflows technology into the locomotive overhauling process, establishes the model of locomotive overhauling process with Petri nets, and provides the basis for the locomotive overhauling process analysis and the optimization. According to the concrete request, this model can fast produce application software system, and when the operation process of locomotive depots changes, this model can rapidly carries on reorganizing to satisfy requests of locomotive depots, and overcomes the shortcomings of efficiency low and consuming long in the formerly development software system process.
