日常生活中，人們經常需要應付各種可能的狀況，對於陌生的狀況，使用者常常會多做或少做了某些事，或無法在預期的時間內完成。其中有一項很重要的原因，即事件之間經常存在著部份的相關性，可稱之為程序導向，例如：A工作需要B工作的資料，或是A工作需要B做完後才能進行。在[Chen01]，作者Chen提出個人工作流程的概念和系統的設計，然而該研究並不支援企業組織所提供的服務。因此，在本論文中我們提出了一個模式，除了一般個人工作流程的功能，也允許組織以服務提供者的角色提供部分流程，並利用Web services與個人工作流程系統互動。在使用上，我們提出一個便於使用者應用個人工作流程的查詢模式，並提出一個架構來幫助使用者，在此架構中包含了服務提供者與樣版提供者，服務提供者提供實際的服務給使用者，樣版提供者是以使用者的目標為導向，提供流程樣版給使用者。對於我們所提出的模式與架構，我們實際建置了一個雛形系統 (PWFMS) 來驗證其實作性與可行性。

In our daily lives, people constantly need to schedule their activities to meet their personal goals. Many of these activities involve the interaction with organization sectors, which must follow certain regulations in terms of input data, doable time and places. These regulations form personal processes. In previous work, [Chen01] proposed a personal process model that define a personal process as a set of tasks and a coordination on the tasks and a personal workflow system architecture. However, the proposed system is solely to facilitate a mobile user in deciding when, where, and how to process a task. We have noticed that many processes initiated by an individual often involve business processes coming from different organizations. Our objective in this thesis is to revise the personal process model proposed in [Chen01] by incorporating business processes existing in different sectors, developing a simpler query method, and extending personal workflow architecture in support of the new model. In our architecture, the management of personal processes involves three parties: the service provider, the template provider and the PWFMS. The service providers supply personal processes, each of which enable users to achieve a specific goal, and keep track of the status of executed tasks. The template providers incorporate several personal processes from different service providers and form a useful template for a user. The PWFMSs assist users in managing personal processes. In order to prove our idea, we implemented a prototype of the architecture.
