基于Petri网的汽车制造业生产物流流程优化

以国内汽车制造企业的生产物流流程为研究对象,利用Petri网技术构建了现有环境下的生产物流流程模型,对其进行了数学特性分析,并使用Exspect软件模拟分析了原流程及优化后流程的优劣。结果表明,应用信息技术优化原有流程,有效降低了生产物流系统运行的出错概率,提高了工作效率。

Optimization of production logistics process of automobile manufacture enterprise based on Petri net

The production logistics process of the modern automobile manufacture is a complex, dynamic and stochastic process of logistics,information flow and capital flow.Taking the production logistics process of a domestic large-scale automobile manufacture enterprise as research object,a model of production logistics process in the present environment was built using the Petri net technology,whose mathematical characteristis was analyzed,and the strong and weak points in the original and the optimized processes were discovered by the simulation using the software Exspect. The results show that the optimization of the original process flow by information technology reduces effectively the probability of mistake and fault in the system operation and enhances the system work efficiency.
