摘　　要：为解决实际爆破工程中方案的优选问题,建立了基于组合赋权-TOPSIS的爆破方案优选决策模型。该模型主要利用逼近理想解排序法(TOPSIS)来实现对方案的优选,从经济、质量、安全3个方面选取了振动速度、飞散距离等12个评价指标,利用层次分析法(AHP)和熵权法相结合的方式确定指标的综合权重,避免了使用单一方法而带来的主观影响或与实际情况不符等缺点,使指标权重更加科学、准确。应用该模型对某工程实例的4个待选爆破方案(Y1~Y4)进行评价,计算得出各个方案的综合优越度分别为34.9%、36.7%、65.2%、65.0%,确定了Y3为最优方案。In order to solve the scheme optimization problem of blasting scheme in practical blasting engineering,a decision model of blasting scheme optimization based on combination weighting-TOPSIS was established.This model mainly use the method of sorting close to ideal solution(TOPSIS)to implement the scheme optimization,from the aspects of economy,quality,safety,three selected the vibration velocity,flying distance,such as 12 evaluation indexes,using the analytic hierarchy process(AHP)and entropy weight method to determine the index of the comprehensive weight,avoid using a single method and the impact of subjective or shortcomings and so on do not tally with the actual situation,make the index weight more scientific and accurate.The model was applied to evaluate 4 blasting schemes(Y1~Y4)of an engineering example,and the comprehensive superiority of each scheme was calculated to be 34.9%,36.7%,65.2%and 65.0%,respectively,and Y3 was determined to be the optimal scheme.
