基于三角模糊数的建筑安全管理评价的TOPSIS法

A TOPSIS Decision Method of Construction Safety Management Evaluation based on Triangular Fuzzy Number

建筑施工企业作为具有较高危险、事故多发的行业,对施工单位进行安全管理绩效评价具有重要的意义。在评价过程中,常会涉及到一些难以量化的定性指标,此时精确数不能很好地刻画评价指标值,而三角模糊数可以较好地刻画专家在评价过程中的不确定信息。本文针对含有三角模糊数情形的建筑企业安全管理评价问题,应用TOPSIS评价方法。并通过实例说明新方法的有效性和可行性。

As a high risk and accident prone industry,building construction industry is of great significance for safety management performance evaluation of construction units.In the evaluation process,it often involves some qualitative indicators which are difficult to quantify.In this situation,the exact number could not describe the evaluation index value,and the uncertain information can be better described by the experts in the evaluation process by using triangular fuzzy number.In this paper,an evaluation method based on TOPSIS method is proposed for the safety management evaluation of construction enterprises with triangular fuzzy numbers.Finally,a numerical example is used to show the effectiveness and feasibility of the proposed method.
