摘要
　　
我們將介紹供應練觀念，而ＳＣＯＲ流程是一個由美國供應練協會提出的基本供應練。一些用來描述流程的工具很少能模擬流程階段性所花費的時間，而時間斐氏圖正好符合正個特性。時間斐氏圖示用來描述系統且用一個符號來描述系統狀態．傳統的斐氏圖用來解決單一事件的流程問題，這篇論文中我們將會訂定我們自己的時間斐氏圖元件和原則，以運用來模擬我們多重事件的流程問題。同一石間我們也將針對ＳＣＯＲ流程中的訂貨生產流程的原料供應，製造，運送三個流程來模擬．最後我們會運用我們的時間斐氏圖運算幾個階段運算的例子。

Abstract
In this paper, we introduce the concept of supply chain and supply chain management. When we want to discuss the issue of the supply chain, the SCOR Model must consider first, so we introduce what is SCOR Model. We know there are several tools to describe the process but fewer can monitor the process with spending time. The Petri Net is the tool to describe the system and we can present the states of the system by its token. But the base Petri Net always focuses on the single case rather than the multiple cases. For the issue, we create some elements and make the definitions of these elements, and then we also define our firing rules of my Petri Net and the relationships between the markings in the mathematical way. By using the elements that we created, we can simulate the process about the multiple cases and we can use the Petri Net to know the time of the process and calculate the total time that the job spent. In the research, we will make a correct proof and we will distribute the three parts (Source, Make, Deliver) of MTO (Make-TO-Order) of the SCOR Model. After understanding all the definitions of the elements of the MTO process, we will translate the MTO process into Petri net and follow the Petri net rule we created before and we will show how the marking and time change in several states.
