Construction Supply Chain Modeling Language and Application Method

In the basis of Chatfield's supply chain modeling language(SCML),this paper keeps the function of describing the supply chain that is at the core of manufactures,adds characteristics of construction supply chain and puts forward the construction supply chain modeling language(CSCML).CSCML can sustain the expressing of construction project structure,work breakdown structure and construction task propulsion which are the features of the construction supply chain.CSCML can not only describe the normal supply chain,but also can describe the construction supply chain.
