因應資訊化作業，大型企業組織透過企業資源規劃系統來整合組織內部與外部的資訊，以促進各種不同的商業功能間資訊的流動與交換。企業資源規劃系統中的主要模組包括商業流程管理。傳統商業流程管理著重在商業處理的自動化。先進的商業流程管理整合了流程邏輯與商業邏輯的功能，以有助於商業策略的規劃。商業流程管理的生命週期包括流程設計、系統配置、流程啟動、診斷四個階段。現有的研究多集中在前三個階段，較少與診斷有關的研究。本篇論文針對商業流程管理系統，研發系統發生錯誤時的診斷工具。本論文提出了診斷模型。此模型由使用者反應的問題中，定義錯誤類別、歸納使用者外部資訊，由商業規則和資料庫綱要中參考整合限制，並對應到系統的內部資訊。我們也開發了追蹤工具，追蹤錯誤可能的發生點，並依不同類別進行問題偵錯。除了針對本身的工作流程中的活動，也對前後的活動進行搜尋，以縮小錯誤偵測的範圍，協助資訊人員有效率排除錯誤。本論文根據一家電子公司的商業流程管理系統的個案研究，顯示我們所提出的診斷模型與追蹤工具有助於問題的偵錯。 關鍵字: 商業流程管理、診斷工具、商業邏輯 / An Enterprise Resource Panning (ERP) system integrates internal and external information andfacilitates the flow of information between all business functions inside and outside an organization. One of the main components of an ERP is the Business Process Management (BPM). Traditional BPM focues on the automation of business processes while advanced BPM has been extended to integrate with process logics and business logics for business strategy. The life cycle of a BPM system consists of process design, system configuration process enactment and diagnosis phases.Much research has been done on the first three phases. Little attension has been paid to the diagnosis phase. This thesis focuses on the design and implementation of a diagnosis tool for BPM systems. We propose a diagnosis model to represent the external and internal view of an error event. This diagnosis model is helpful for the troibleshouting to capture the status of an error event. Moreover, a bug tracer system is devlopement based on the proposed diagnosis model to diagnose the problem of workflow activities, and also trace before and after activities in the workflow, narrow the scope of error detection. Case studies from an electronic company demonstrate that the proposed diagnosis model and the tracer tool are helpful for troubleshooting.
