串行离散事件动态系统的建模、分析及设计
Modelling and Analysis in Discrete Event Dynamic System
-
摘要: 本文提出的离散事件动态系统(DEDS)建模新方法,是从K+1个缓冲库状态中抽取有库存(P-o)和有空位(Pk)两种状态,合并到邻近的工作站中,构成相应的等效工作站,再将所有等效工作站联成DEDS生产系统,从而导出各项生产指标,这种方法是将离散断续工作的多级生产线转化为连续工作的多级生产线,于是可以采用常微分方程数学工具,得出静态和动态的精确分析解,较好地解决了离散断续工作系统建模的难题.Abstract: A new method, which is called equivalent workstation, is proposed for modelling and analyzing the discrete event dynamic system (DEDS), and some performance indexes are obtained. Finally an example is used for illustrating the application of this method.
