近二十年來由於資訊技術不論在軟體或硬體方面都有的快速成長，這使得開發製造執行系統開發面臨更多元的挑戰。另外一方面隨著網路技術的應用與開發日趨成熟，元件式的軟體開發以及相容於各種不同異質性平台的程式將成為主流。為了能夠充分利用這些新科技所帶來的好處，建立一個可與舊有系統相容而又能結合這些不斷演進的資訊技術架構將是未來的趨勢。
模式驅動架構（Model-Driven Architecture）是物件管理組織（OMG）近年所提出的軟體開發架構規格。在這一個架構之下，軟體開發分成三個階段：（1）與實作平台無關的模型建立；（2）建立與特定實作平台相關的模型；（3）實作程式碼。一個中性（與實作平台無關）的模式將可不斷的重複利用在不同應用環境，透過特定的轉換就可以達到與不斷演靜的資訊技術相容的目標。在本論文架構中包含三個主要的開發階段來完成模式驅動架構的製造執行系統：（1）分割並且建立製造系統的核心功能模組；（2）發展特定平台的功能模組；（3）實作與建立元件程式碼。這些開發出來的功能元件將可以輕易的部屬在不同的應用環境，若要應用在不同的實作環境，那麼只需透過轉換不同平台資訊的功能模組就能完成。如此一來模式驅動的製造執行系統架構便可以靈活、彈性、以及快速的反映和擴充在複雜的製造環境以及異質性的電腦作業環境。
在研究中實作了一些簡單的功能元件，這些元件可被部署在EJB的分散式環境下。相關的功能元件可以重複的步驟分析實作出來，進而組合成製造執行系統的核心功能模組。元件的設計降低了系統的複雜程度也相容於分散式的環境，同時這些元件也可以透過特定平台模式的修改而重新實作部署，以達到重複利用和相容於不同實作平台的特性，而不需要將模式重新設計。

A Manufacturing Execution System (MES) is an on-line integrated computerized system that is the accumulation of the methods and tools used to accomplish production [Michael, 1997]. In the latest two decades, the IT has made great progress both in hardware and software development. The design of computerized systems for MES has changed dramatically with these advance technologies like Distributed Computing Environment (DCE). In order to exploit the niches of new technologies, we need a neutral architecture to support the evolving IT and the legacy systems.
The Model-Driven Architecture (MDA) is the recently underway specification of OMG. The MDA dedicates to provide an open and vendor-neutral approach of software system development and leverages the value of OMG’s standards. The framework of MDA-based Component-Oriented MES (COMES) proposed in this thesis intend to take the advantages of MDA and component-oriented technology via three developing stages: (1) partitioning and constructing COMES core functions models, (2) developing the COMES function models of PSM, and (3) implementing and building codes. By adopting this framework, it is expected that an agile, flexible, extensible and interoperable MES system can be established under a complex manufacturing environment with the consideration of diverse legacy systems and heterogeneous platforms.
From the implementation results conducted in this research, the framework of MDA-based COMES, it demonstrates the merits of this new specification of OMG in manufacturing domains. The MES can be built in an efficient way and possesses the advantages reusability and interoperability when system requirements and platforms are changed.
