價值工程資訊管理系統分析與實作--以台北市捷運工程為例

Abstract

價值工程是一種創造品質與成本雙贏的方法及技術，亦是一種總成本控制的工具。其著重點在於一方面確保產品或服務之品質及機能，另一方面剔除不必要的成本浪費，以獲取最大的效益。而其主要之目的，則是透過研析團隊針對產品或服務的特性作有系統的分析。直到能夠分離需要與不需要的機能時，即可完成，並發展替代方案提供決策者做最後的決斷依據。而目前的價值工程文件多為書面報告，若有需要參考的時候，則必須先找到那本報告然後手動翻閱，極為麻煩不便，且受到時間、地點的侷限。 而所謂文件管理系統，即是一套針對某種文件或是某些文件所建立的電子化資料庫以及提供操作的前端介面，透過電子化技術，可以將難以保存且難以傳輸的書面資料轉化成電子資料庫，利用網際網路隨時隨地皆可取得的優點，使過去的歷史資料可以做最大程度的運用。 本研究為因應國內公共工程應用價值工程日趨普遍，尤以台北市捷運工程為最，但歷史資料多為未整合過之一本本書面資料，這對往後的價值工程研析案在歷史資料的應用上是一個很可惜的侷限。本研究意圖採用實體關係模型、五階正規化等資料庫建置技術、微軟公司最新推出的.NET平台以及用來取代傳統ASP的WEB應用程式建置技術將價值工程研析報告轉化為一個可線上輸入、修改、檢核、查詢之網際網路資料庫系統。如此應用資訊技術及網際網路以利價值工程研析歷史資料的建置、分析及搜尋，期望簡化往後價值工程研析過程中所花費在資料收集、分析的部份，俾可使前人的智慧結晶做最有效的應用。

As a method and technology to ensure the win-win balance of both quality and cost, value engineering can also be used as a tool to control total cost. Its emphasis, on the one hand, is the assurance of quality and function of product or service, and on the other hand, is the avoidance from unnecessary dissipation of cost, so as to achieve optimal efficiency. The major goal is to facilitate systematic analysis on characteristics of product or services for the research team, separate necessary and unnecessary functions, and develop alternative proposals for the decision-makers. Currently, most engineering documents are paper-based, causing tremendous inconvenience in the locating and browsing of the report needed for reference. Besides, the utilization is under the limitation of time and location. Document management system is comprised of digitalized databases and front-tier interface for documents of a certain type or quantity. Through the digitalization technology, paper-based data that are not easily archived and transmitted can be transformed and integrated into the digital database. Further, the accessibility of Internet beyond time and location facilitates optimal utilization of archived data. The application of value engineering in public construction has enjoyed growing popularity in Taiwan, especially in the construction of the MRT system in Taipei. However, most archived data are not integrated but only bound volumes, hampering the application of history data for future value engineering analysis. In light of this, our study intends to apply database implementation techniques, including Entity-Relationship Model, Fifth Normal Form, Microsoft’s latest .NET platform, and WEB application programs (replacing traditional ASP) to transform value engineering analysis reports into an Internet database system that allows online entry, modification, check, and search. This integration of information technology and Internet to facilitate the implementation, analysis and searching of value engineering analysis on archived data is expected to simplify data collection and analysis procedures, so as to achieve optimal utilization of previously accumulated intelligence.
