臺北捷運局成立之初，國內並沒有捷運建設的工程經驗，因此，聘請外籍總顧問借重其經驗與能力，協助規劃台北捷運系統，本局將多年累積的捷運建設經驗，以制度化、有系統地管理、保存。 本文簡述知識管理概念、說明如何找出捷運工程核心技術知識、本局採行的相關管理制度，如何運用資訊技術協助管理，以及列舉實際運用案例加以說明，並以知識的普及度、成長度、擴散度、知識整合力、知識轉化力及創造力，來檢視本局知識管理的執行成效，以提供工程業界在推動知識管理上的參考。

When the Taipei City Department of Rapid Transit Systems (DORTS) was established, Taiwan did not have MRT construction experience. This led DORTS to hire foreign consultants to assist with MRT planning. Since then, DORTS has gained experience in the planning, construction, and maintenance of a rapid transit system while systematically documenting this knowledge. This paper outlines the concept of knowledge management and uses specific examples to illustrate key elements of its application, including obtaining the core MRT technology needed for knowledge management, adopting management methodologies, and using information technology to assist in management. It also describes how to evaluate the effectiveness of knowledge management based on performance metrics related to popularity, growth, extension, integration, transformation, and creativity. Furthermore, this paper provides a case study that can encourage others in the engineering industry to apply knowledge management in their own work.
