Abstract

The fundamental problem of the emergency repair and construction is to evaluate the efficiency of the support plan of emergency supply for earthquake repair. This paper constructs reasonable evaluation model of each support plans' input and output based on DEA and gets the relative efficiency of each support plans to choose the rational plan. When fuzzy DEA can not evaluate the efficiency of support plans in the special case which is after the earthquake and the outputs are fuzzy data, it can get average efficiency by using Monte-Carlo method to simulate the outputs of each support plan and provide decision makers with scientific basis for choosing the rational support plan.

基于模糊DEA的地震抢修应急供应保障方案
评价地震抢修应急供应保障方案的有效性是抢修建设的根本问题。本文基于DEA构建了各保障方案投入产出的合理评价模型,得到各保障方案的相对效率,以选择合理的保障方案。在地震后的特殊情况下,当模糊DEA无法评价各保障方案的效率,且输出的是模糊数据时,利用蒙特卡罗方法对各保障方案的输出进行模拟,得到平均效率,为决策者选择合理的保障方案提供科学依据。
