基于变异系数权重的灰色关联投影法在安全绩效评价中的应用

在提出施工企业安全绩效评价指标体系的基础上,运用灰色关联投影法对企业安全绩效进行评价。为避免指标的相对重要程度因人为赋权的主观性影响和指标权重分配的均衡化以及指标之间因量纲不同而对权重的影响,采取了变异系数法来对各指标确定权重。之后针对实地考察的施工企业进行实证分析,运用比较安全学的思想对安全绩效进行纵向对比,依据评价体系灰色关联度大小来判断施工企业安全绩效的水平高低。进而诊断出各企业安全绩效的优劣,为同类型的企业实际开展安全绩效评价提供指导性的方向和建议。

Application of Grey Relation Projection on Safety Performance Assessment Based on Variation Coefficient

Evaluation index system of construction enterprise safety performance is proposed,applying the grey correlation projection to the enterprise safety performance evaluation.In order to avoid human subjectivity of the relative importance on indicators and the equalization of index weight distribution,the variation coefficient is used to determine the weight of each index,which can also prevent the effects of different dimension on index.According to comparative security idea and on-the-spot investigation and analysis of construction enterprise,a longitudinal comparison of safety performance is conducted.The safety performance of construction enterprise is judged by gray correlation.Then safety performance of each enterprise is fur-ther recognized,which can provide guidance and suggestions for the same type of enterprises to carry out safety performance evaluation.
