摘　　要：系统分析大坝施工的机械配置、混凝土坝面分仓等控制性因素,通过计算机施工仿真,分析施工方案的施工强度、工期等决策因素,结合机械设备投资费用,运用基于熵权的多目标决策理论,得到决策熵权,结合决策者的主观权重,建立浇筑施工方案多目标决策模型.工程应用说明,应用熵权进行多目标决策,能够较好地反映各决策指标的差异程度,具有概念清晰、实用的特点.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.
