摘要

近年來，由於全球化競爭時代的來臨，企業面臨了日益嚴苛的競爭環境，為了讓企業能夠保持競爭力，企業需要透過建置各式資訊系統，以應變外在市場變化及競爭對手的挑戰，及整合企業內部的各式作業流程，企業為達成自動化作業的目的，開始導入了資訊系統，並開始利用工作流程(Workflow)來串連各種商業活動。在商業邏輯的發展日漸龐大的情況下，進而突顯了在工作流程設計上所面臨的問題。
本研究主要在探討基於設計樣式的工作流程設計方法，目前常見的工作流程設計方法是從無到有建置一套流程，必須付出大量的開發時間，當工作流程的業務需求會隨著時間而不斷改變與增加時，就必須修改現有流程的設計以符合新需求，當經歷了幾次需求變更後，流程架構因不斷修改設計而變得支離破碎，進而得付出更多的維護成本。
本研究將針對上述問題提出一套工作流程框架，並利用物件導向樣式設計來導入擴充機制於工作流程框架中，這樣不僅在日後開發新流程時，除了能縮短開發時間，更能因應不同的業務需求來擴充現有的流程設計，進而降低維護成本。

In recent years, the era of global competition, enterprises are facing increasingly tough competitive environment, in order to allow enterprises to remain competitive, companies need to build all kinds of information systems through to strain the external market changes and competitive challenges , and integrate various processes within the enterprise, the enterprise to achieve the purpose of automation, began to import the information system, and start using the workflow to concatenate the various business activities. Logical development in the business's growing, it is further highlighted in the workflow design problems faced.
This study aimed to explore the design patterns based workflow design methods, the current common workflow design approach is to build a process from scratch, you must pay a lot of development time, when the business needs of the workflow over time changing and increasing, you must modify the design of existing processes in order to meet the new demand, when demand has undergone several changes, due to constantly modify the design process architecture becomes fragmented, and thus have to pay more maintenance costs.
This study will address these issues put forward a workflow framework, and using object-oriented design patterns to import extension mechanism in the workflow framework, so that not only the development of new processes in the future, in addition to shorten development time and more responsive to the different business demand to expand the existing process design, thereby reducing maintenance costs.
