場區控制資訊系統之IDEF0參考模式

摘要

本研究之主要目的，在於以IDEF0爲描述工具，提供一場區控制資訊系統之參考摸式。而在模式構建的過程中，所考慮的控制架構與功能、資訊流、及訊息傳遞的內容與對象具有密切的關係，因此，本研究將以整合性的觀點探討三者之關聯性，以作爲構建場區控制資訊系統摸式之基礎。由於電腦處理及通訊技術上之進步，使得分散式控制架構成爲較具優勢的選擇；在控制功能方面，本研究則以Brower的控制功能爲藍本，將系統分爲數個執行程序，以完成分散式控制架構所需之功能。再者，更導入物件分類的理念於IDEF0方格中，展現系統之功能活動、資訊流及傳遞於各物件間之訊息，其過程所表現構建場區資訊系統摸式之手法，亦可供業界於建立系統時之參考。

Abstract

A reference model of a Shop Floor Control Information System (SFCIS) using IDEF0 methodology is presented in this paper. Experience shows that in developing an SFCIS model the control information flow and the passing messages will highly relate to the applied control architecture and control functions. Therefore, in this paper an integrated perspective over them will be focused and serve as a basis for developing the desired IDEF0 reference model. With the incredible improvement in computer and communication technologies, a heterarchical shop floor control architecture is no longer unreal and has been considered widely. In this paper, the Brownes Production Activity Control (PAC) model is used to determine the concerned control functions. The object-oriented concept is also introduced in building the IDEF0 block. Consequently, the control information flow and message passing scenario between objects can be addressed simply in the IDEF0 model. In fact, the development procedure of this reference model also reveals a systematic approach close to the reality.
