摘要
介绍了事件序列图的概念及基本图符,提出了基于事件序列图的供应链建模方法,给出了其建模步骤,并结合示例说明该方法的建模过程。讨论了模型的应用情况,对供应链的速度、成本、资源利用率等性能测度进行定义。最后,运用蒙特卡罗仿真方法对模型模拟运行并对结果进行分析。
This paper introduces the concept of Event Sequence Diagram（ESD） and its basic graphics symbols. Modeling method for a supply chain based on ESD and its steps are presented. A demonstration is given to show the modeling process. In this paper, the application of the model is discussed and some measures of supply chain performance, such as speed, cost, resource using rate, are defined. Finally, model is run by Monte Carlo simulation. The results show the validity of the method.
