Abstract:	近年來許多企業都面臨了提昇競爭力、降低成本及迅速地推出產品與服務等問題。工作流程(workflow)技術提供了新的方法幫助企業有效地管理商業程序(business process)，根據工作關係、組織結構、員工能力及現有的資源進行分配與排程，其縮短處理時間、善用企業資源、並提昇企業整體的效率。而程序定義(process definition)是工作流程的核心，程序定義定義了所有相關商業程序的資訊，這些資訊包含了企業程序中的所要完成工作、參與的資源及有關規則與條件，最後交由工作流程管理系統(Workflow Management System)執行。由於程序定義的完整性與正確性會影響整個企業程序的執行結果，因此如果我們能夠完整且無誤的表達出程序定義，將可以避免執行後的錯誤。所以在本篇論文中，我們針對工作流程的程序定義之模式化(modeling)提出整合UML (Unified Modeling Language)與派翠網路(Petri Nets)的方法。我們的方法主要分為四個模式化階段：(1) 程序需求獲取(elicitation)階段；(2)邏輯設計階段；(3) 程序定義分析階段；(4) 實際工作配置階段。 Recently many enterprises face the pressures, such as market competition, reduction of cost and rapid development of new products and services. The workflow technique provides a new mechanism to help enterprises manage business processes efficiently, which is according to relationship of works, organization structures, capabilities of members and all of resources. The workflow technique reduces the time of process, allocates resource powerfully and improves the performance of enterprises. Furthermore, process definition is the core of workflow. Process definition defines all of necessary information related to business process. The information contains constituent tasks, participated resources, rules and conditions. The process definition will be executed by the workflow management system eventually. Therefore, the integrity and accuracy of process definition will affect the result of execution. In this paper, we propose UML(Unified Modeling Language) and Petri Nets approach for workflow modeling. Our approach consists of four phases: (1) process requirement elicitation phase; (2) logical design phase; (3) properties analysis phase; (4) physical deployment phase.
