Evaluation of Construction Supply Chain using Preference Restraint Cone DEA Model

摘要

The internal pressure and external incentive of construction area contributed to the study of supply chain management, construction calls for the construction supply chain management's (CSC) research and practice. Combining with features of Data Envelope Analysis (DEA) and CSC, the basic framework of CSC comprehensive performance evaluation was built from the aspect of consumption and output. Under such framework, the indicator system for comprehensive evaluation was also constructed. Because traditional methods of DEA do not consider the impact of preferences of the input and output indicators for decision makers, an improved preference restraint cone DEA model was presented; an example was given for analysis. The results show that the DEA with the preferred model omissions the pseudo effective construction supply chain and reflects the subjective preferences of decision makers. It is an improvement from past research of the model.
