| 摘要: | 目前國內營建業在規劃、基本設計階段之成本估算，大都憑藉專業估算人員，依據規模相似之工程經驗與資料，對工程成本進行「粗估」或「概算」而得。但我國營造廠多屬於中小型企業，專業人員異動過於頻繁，類似案例或估算經驗不易傳承。 本研究嘗試以案例式推理(Case-Based Reasoning, CBR)之技術，由案例表示過去之知識與經驗，來解決估算作業經驗傳承不易之問題。本研究以過去102個實際工程案例為基礎，建立一適用於建築工程於規劃、基本設計階段之成本概算系統。此系統輸入之參數為建築物所在縣市、基地面積、地上樓層數、地下樓層數、總樓地板面積、外牆面積、與地下室周長；而其輸出之結果為假設工程、基礎、結構體、外牆裝修、內牆裝修、平頂裝修、門窗、電梯、水電、空調、與消防等各項工程費用以及總工程費用。此系統可提供新進人員、業主或承包商在規劃階段，對建築工程成本建立整體概念，使其有效掌握專案之進行。 Cost estimating at the planning or preliminary design phase is usually performed by experienced estimators based on past experiences. However, domestic construction companies are relatively small in which frequent personnel turnover impedes transition of the experiences. This research attempts to solve the above problem by employing a case-based reasoning (CBR) technique into a computer system that comprises of 102 past construction cases. The input to the system is a set of building related parameters that include name of county, site area, floors above ground, floors below ground, gross floor area, exterior wall area, and perimeter of basement. The output of the system is a set of various costs for temporary construction, foundation, structure, exterior wall, rough interior, finishes, elevator, plumbing, and HVAC, etc. The CBR system provides construction rookies, the contractor as well as the owner a whole picture of the construction costs to facilitate the construction progress. |
