灰色关联度分析在地铁工程项目安全评价中的应用研究

本文将灰色系统理论引入到安全评价中,通过计算各安全风险管理单位的灰色加权关联度,对其相对优劣性进行排序,从而挑选出最佳安全风险管理单位,并结合实例,详细介绍了灰色评价模型的计算方法和步骤。实践证明,其具有较强的应用价值。

Research on Safe Evaluation of Subway Engineering Projects Based on the Gray Relation Analysis

In the beginning of this paper,on the basis of the existing evaluation system,safe evaluation system of subway engineering projects is reconstructed.Then the grey system theory is introduced into the evaluation system.Following by this,the best bidder could be selected by the way of calculating the weighted gray relation degree of all bidders and arranging the relative strengths and weaknesses.In the last section,a case is used to introduce the calculation method and procedure of gray evaluation model in detail.The practice has demonstrated that the evaluation model is simple,easy to understand,and with a strong application value.
