基于仿真的生产线控制规则性能评估技术研究

综合考虑了工件的加工时间、到达率和交货期等随机因素，仿真分析了不同故障率下调度规则和路径选择规则组合的性能，并给出了每种性能评价指标下最优的规则组合。另外，在动态生产环境中，为了支持快速仿真分析，提出了基于建模模板的仿真建模方法。该方法以建模元素和仿真控制逻辑分离的原则为指导，采用面向对象仿真建模技术，构建面向生产线的过程控制模型，实现控制模型的模块化，提高了模型的可重用性和可扩展性。

Performance Evaluation Technology for Control Rules of Production Line Based on Simulation

Considering synthetically the stochastic factors like processing time, arrival rate and due date of the job, combination performance of dispatching rules and routing rules was analyzed under different breakdown rates by simulation and the most optimized combination of dispatching rules and routing rules were given under each performance measure. Under dynamic production environment, in order to analyze rapidly by simulation, an approach of simulation modeling was presented based on template. The approach, considering the modeling element and simulation logic respectively as well as adopting the object-oriented simulation modeling methods, was used to build the control model for production line, and to accomplish modularization of control modeling. It improves the reuse and expansibility of simulation model.
