工作流程中人工任務之研究

Abstract

在工作流程管理中，通常會透過對組織模型的查詢以決定適合執行某項作業的人員清單。本論文針對該領域的兩個議題做討論：其一，每個企業或組織內部的組織模型可能有極大的差異，工作流程系統內建的組織模型要如何跟企業的組織模型匹配？此外，工作的分派通常由非技術人員進行，因此，要如何設計一個兼顧簡單與功能面的查詢模式，讓非技術人員能夠順利的應用？其二，工作流程中，需要人員介入的任務稱為人工任務，這些人工任務通常使用表單式的介面來接受使用者的輸入。然而，建造這些表單牽涉到將資料在介面與資料模型間作連結與轉換，而這些程序通常既繁瑣又容易出錯。是否存在一個有效率又能降低犯錯的程序？在本論文中，我們將闡述我們解決上述問題的動機以及設計。

Human tasks are tasks driven by workflow management systems that require human intervention to complete. Human tasks are typically assigned to participants by specifying people queries against an organization model. However, the organization models of enterprises may vary greatly. How can a workflow organization model be developed that can adapt to an enterprise organization model when a WfMS is deployed to an enterprise information environment? Besides, tasks are assigned to participants by non-technical people. How can people queries be developed that are powerful enough but still easy to use by non-technical people? Furthermore, before a human task can be managed by a workflow management system, it must at first be constructed. In most cases, user-friendly GUIs are needed for humans to interact with human tasks. Is there a mechanism for constructing GUIs for human tasks efficiently? These issues lead to two research topics: the management and the construction of human tasks. In addition to presenting our motivation, we will report our design and implementation of a proposed solution to these issues in this thesis.
