精簡營建的概念來自於日本豐田汽車工程師大野耐一（Ohno）的精簡生產系統的研究理論，大野將狹義的人工產能、機器產量的一般製造業觀點轉向著重於整個生產系統架構的改善，所以精簡生產的內涵是整個生產系統執行的最佳化。精簡營建也利用此概念來改善營建產業的生產活動，而供應鏈管理則是精簡營建最重要及具體的管理活動，研擬出良好的供應鏈架構及管理系統，對整個營建產業將有深遠之直接與正面的影響。 近年來國內營建供應鏈之研究多以製造業、物流業觀點，進行相關之分析報告，但因產業特性不同，即使以物流生產觀點解決部份供應問題，但營建業界目前在整個專案執行過程中最嚴重的問題卻是因缺乏整合而在各個過程之間因介面產生大量的損耗浪費，這些損耗當然造成效率降低、時間工期拉長及成本的增加。而針對整個營建供應鏈的結構進行整合及介面協調對精簡營建則會有實質及巨大的影響，因此依營建產業現有特性並以鋼筋工程為例建構相關供應鏈管理架構及價值流分析模式，以期消除損耗增加營建產能為本研究之目的。 The concept of lean construction is based on the lean production was developed by Toyota led by Engineer Ohno. Ohno transferred the common narrow view of productivity of manufacture to the improvement of the throughout configuration of production, consequently, the intension of lean production is the optimum of production system. The supply chain management is the key point of lean construction, to propose an ideal configuration of construction supply chain management will tremendously contribute to construction industry-wide. The research of construction supply chain in domestic almost focus on the view of production or logistics in recent years, but the characteristic of production is different from construction, therefore, the approach of the production can’t be utilized completely in construction. The waste is the acutest problem in construction supply chain because of lacking integration between interfaces. The research content provide a integrated viewpoint of construction supply chain configuration as well as coordination of interfaces, and the criteria of supply chain management in timely metric rule by value stream analysis （VSA） method. The elimination of waste in construction is the purpose of this research.
