基于改进灰色关联分析法的工程防护效能评估方法

为研究评估工程的防护能力,提出了工程防护效能应具备 6个指标,鉴于各指标的属性、重要程度和可比性都不同,使得防护效能的方案比选具有明显的灰性.通过对经典的灰色关联分析法的分析,得出其存在的局限性,进而对其从分辨系数、熵权法和投影法方面进行改进.对工程防护效能进行评估,并与经典的灰色关联分析法相比较,验证了该模型的可靠性和可行性.可以将此模型推广应用到实际工作中.

Evaluation of defending efficiency in engineering based on improved grey interrelated analysis method

In order to research and evaluate the defending efficiency in engineering,the six indexes involving the defending efficiency of engineering were put forward.Each index has its own attribute,importance and comparability,which makes the process of scheme's selection grey.Analysis of classical grey interrelated analysis method indicated its localization,and improvement was made on distinguishing coefficient,entropy weight and projection method.Through the evaluation of defending efficiency and comparison with classical grey interrelated analysis method,the model proves to be credible and practical.So this model can be used extensively in actual task.
