動態環境中的跨企業工作流程系統之設計

Design of a Flexible Interorganizational Workflow System in Dynamic Environments

指導教授 : 項衛中

摘要


企業為了更彈性因應市場變化,尋求企業外部的合作進行策略聯盟或成為供應鏈的成員整合彼此優勢。企業間的資訊交流必須藉由整合與管理彼此工作流程的方式,來確保跨企業工作流程中資訊的一致性和協調性。由於跨企業工作流程常因外在環境必須做適當的調整,如流程的新增、刪除及修改等,因此必須有適當的資訊系統能執行跨企業工作流程,並且在流程執行時可以有彈性的做到動態變更,增加企業的競爭優勢。 一個良好的跨企業工作流程需考量自主性、隱私性與彈性三項特性,本研究提出以工作流程聯盟的概念建構跨企業工作流程系統。工作流程聯盟可以整合異質性的工作流程,並保有企業內部流程的自主性及隱私性,此概念又可幫助企業根據不同需求組成不同的聯盟,建構相關的工作流程以便於達成共同的合作目標,滿足跨企業工作流程所需要的彈性要求。而版本控制可管理在跨企業工作流程的建構與執行時的變更,使面對環境變化而必須立即變更的工作流程更具彈性。運用上述特性建構跨企業工作流程系統,可確保合作時一致性和協調性及面對環境變化的彈性,使企業能順利達成共同的目標。 本研究引用工作流程聯盟的概念,運用資料庫存放跨企業工作流程的版本資訊,再藉由版本控制輔助跨企業工作流程的建構與變更,使流程於新增、刪除與修改等變更情形時,能更有彈性的變化。本研究運用JADE代理人技術建構跨企業工作流程管理系統,並以情境範例驗證本研究的可行性。

並列摘要


To be more flexible in responding to global market changes, an enterprise seeks cooperation with strategic alliances or becomes a member of the supply chain. The workflows of cooperative activities may include many sub-workflows in participating enterprises. Due to the frequent changes of the environment, the inter-organizational workflows need to be modified (e.g., to create, delete, or change) to fulfill requirements. Therefore, enterprises need appropriate information systems to support inter-organizational workflows and to be flexible for dynamic changes. A good inter-organizational workflow needs to fulfill the requirements of independency, privacy, and flexibility. This research applied the workflow federation model to develop inter-organizational workflows, such that each company can keep its own independency and privacy, and to design individual workflow federation for each collaborative operation. Version control was applied to manage the alterations of construction and implementation of inter-organizational workflows, and this way might keep workflow to be more flexible to changes. This research proposed to apply workflow federation modeling and to use a database to keep the version data of inter-organizational workflows. The JADE agent system was applied to implement the proposed inter-organizational workflow management system. Two testing scenarios were realized in the implemented system to verify the feasibility of this research.
