Used priority degree evaluation method based on entropy weight to prefer the best ventilation system reform program for Liu Dong coal mine, objectively determined each index weights, established correlation function, filtered out the program four as the best solution. This method through the goodness value not only be able to determine the best solution, but also able to draw the extent of the various options close to the best standard. The optimal solution has been applied to Liu Dong Coal Mine, not only improved the problems of the original mine , but also got a lot of economic benefits.%把熵权法和优度评价法结合起来用于刘东煤矿通风系统改造方案的优选,客观的确定了各指标的权重,建立了关联函数,筛选出方案四为最佳方案.该方法通过优度值不仅能够确定最佳方案,而且能够得出各个方案接近最佳标准的程度.得到的最优方案已经应用于矿井实际,不但原有矿井存在的问题得到改善,而且获得了很大的经济效益.
