摘　　要：影响矿井通风系统设计方案合理性的因素主要分三个方面,共12项评价指标。应用专家评议法、层次分析法和模糊群体决策法,对同一矿井通风系统设计方案的评价指标体系进行权重分析,得出不同的评价指标权值。根据计算结果进行比较分析,可知当同组专家对同一矿井通风系统设计方案评价指标进行权重分析时,虽然选用专家评议法和模糊群体决策法这两种不同方法,得出的评价指标权重大小及排序基本一致;而当不同专家或分析者对同一评价指标体系进行权重分析时,由于他们对各评价指标的重要性偏好不同,不同方法计算出的评价指标权重大小及排序不一致。The influencing factors on the rationality of the design scheme for mine ventilation system have three aspects,which include 12 indexes.There are three calculation methods of the evaluation index weight in general,which include the delphi method,the analytic hierarchy process and the fuzzy group decision.These methods were used to analyze the evaluation index weight of the same design scheme for the mine ventilation system,which acquired different evaluation index weight in this paper.According to the comparative analysis of the calculation results,the following conclusions were obtained.When a group of experts analyzed the evaluation index weight of the same design scheme for the mine ventilation system,although two methods of delphi method and fuzzy group decision were used to analyze the evaluation index weight,the weight size and order of the evaluation indexs were nearly the same.But when different experts or analysts analyzed the evaluation index weight of the same design scheme for the mine ventilation system,the weight size and order of the evaluation indexs were not the same by using different methods.It was because that different experts or analysts had different importance preference of the evaluation index weight.
