Abstract:	隨著電子商務的日漸普及，工作流程管理系統(Workflow Management System)已經被廣泛地應用在企業中。傳統的工作流程管理系統常會面臨與外部系統整合困難的問題，網際服務技術(Web Service)的快速發展，解決了異質平台溝通問題，也將軟體發展與資訊整合帶入了一個新的領域。商業流程執行語言BPEL4WS(Business Process Execution Language For Web Services)是專為整合網際服務(Web Service)而制定的一項規範標準，配合相對應的流程執行引擎，自動的執行所定義的網際服務組合流程，BPEL4WS雖然有效的解決異質平台溝通問題，並且藉由服務組合提供複雜的商業流程，但卻缺乏工作流程管理系統中與人互動的界面。本論文中將以Workflow Management Coalition (WfMC)所訂定的標準工作流程規格為基礎，設計並實作結合以BPEL流程執行引擎為執行環境的工作流程管理系統。本論文主要包含以下幾點貢獻：設計一個以WfMC 標準工作流程規格為基礎的Workflow Management System系統架構。擴充BPEL，加入與人互動的網際服務界面，以BPEL Engine 來執行 Workflow Process。實作由WfMC所定義的Interface：Process Definition Interchange 與Workflow Management Application Programming Interface。 Due to the E-Commerce is getting more popular，the Workflow Management System is broadly used in the enterprise. Traditional workflow management system always facing problem while integrating with systems outside their enterprise, the rapid development of the Web Service technology solve the problem to communicate with different platform, which also bringing the software development and information integration into a new area. BPEL4WS (Business Process Execution Language For Web Services) is a standard dedicated to Web Service integration, along with process execution engine, which can execute composted web service process automatically. Thought the BPEL4WS solve the communication problem with different platform effectively. And also provide complex business process flow through service composition, but it lack of the user interaction interface, which is popular in workflow management system. This thesis will design and implementation a workflow engine, which use a BPEL engine as its run time execution environment, based on the standard defined by the Workflow Management Coalition (WfMC). This thesis has the following major contribution: Design a Workflow Management System architecture, which follows the specification that defined by WfMC. Extend the BPEL language, by introducing the human interaction web service interface and execute workflow processes by the BPEL engine. Implement the standard interface defined by WfMC: the Process Definition Interchange and Workflow Management Application Programming Interface.
