Multi-objective Decision Based on Entropy Weight for Construction Scheme of Concrete Dam

LIU Quan1,WANG Zhong-yao2,3, HU Zhi-gen1(1.State Key Laboratory of Water Resource and Hydropower Engineering Science,Wuhan 430072,China)(2.Mid-South Design and Research Institute for Hydroelectric Projects of CHECC,Changsha 410014,China)(3.College of Civil Engineering,Tianjin University,Tianjin 300072,China)  
The main factors of dam construction,such as the contruction machines scheme and the partition of lift surface are systematically analyzed.And then the index of construction schemes,such as constrction intension and construction duration,are calculated by computer constrction simulation.By means of multi-objective decision theory and entropy weight theory,the entropy weight is gained.Combining with the subjective weight of decision-maker,the multi-objective decision model of construction schemes is established.The appliance of practics shows that the dicision results made by entropy multi-objective decision model indicates the differences between the decision index and comes with clear concept and practical.
