用改进的AHP方法确定既有建筑加固方案的权重系数,可以一次得到权重值,且不需要进行一致性检验,避免了调整判断矩阵的盲目性。通过系统聚类分析法对群决策中的专家进行了分类,并以此为依据,给各位专家赋予了一定的权重,调整了专家认识事物的不一致性,用科学的方法来确定既有建筑加固方案的优选。 The improved AHP method is used to determine the weight coefficient of the existing building reinforcement scheme. The weight values ​​can be obtained at one time, and no consistency check is required, which avoids the blindness of adjusting the judgment matrix. The system cluster analysis method was used to classify the experts in the group decision-making, and based on this, the experts were given a certain weight, the inconsistency of the experts’ understanding of things was adjusted, and the reinforcement of existing buildings was determined by scientific methods. The preferred solution.
