本研究針對製造執行系統在半導體業界之應用提出一套流程管理之方法，以建模及模擬的分析來協助設計製造執行系統處理資訊之活動，以及整合現場工作流程提出完整的方法論。雖然前人文獻中對製造執行系統多有描述，但對於其中處理資訊的程序卻模糊不清，而且少有文獻提到製造執行系統和工廠現場工作流程之間潛在的關係。針對此點，本研究著手於了解製造執行系統完整定義、處理資訊活動程序、各功能模組之間處理資訊之關連以及跟半導體加工工作流程之間的互動關係。 本研究採用三種流程管理方法論，首先使用IDEFØ定義製造執行系統中各活動，IDEFØ方法論提供製造執行系統活動詳細的資訊輸入、輸出、控制及機制定義。第二，使用活動圖建立製造執行系統各模組處理資訊的程序和決策點，以及建立半導體之工作流程。第三，將活動圖之程序轉換成Petri net完整圖形，可以同步顯示資訊流及工作流之互動關係，並且加上時間參數估計製造執行系統處理資訊之程序對工作流程的時間影響。本研究提供給以物件導向方式進行執造執行系統設計及改善之研究者新的方法工具，可進一步了解詳細流程定義及規畫系統。 This paper presents a model and simulation for analyzing Manufacturing Execution System (MES) in semiconductor fab, which aims to optimize production activities on the shop floor in a changing environment. Despite the large number of studies that have been done on MES over the past few years, little attention has been given to its potential relation on the semiconductor fab work floor. MES is popular with single plants for controlling and monitoring the production situation. Our model integrates MES with Manufacturing Information System (MIS) to access their effect on both data and object flow as well as decision points in IC production. We used IDEFØ to define the activities in MES. IDEFØ provides a formal method of describing processes or systems, using several techniques to avoid the complex diagrams that could result from an attempt at a complete description using other methods. And activity diagram with UML is build for the activities with the modules in MES. Activity diagrams represent the business and operational workflows of a system. An Activity diagram is a dynamic diagram that shows the activity and the event that causes the object to be in the particular state. Finally, the CPNtools is used for modeling the CMOS Workflow, MES information flow and Case discussion.
