基于信息熵和灰色关联分析的工程评标模型

Bid evaluation model of construction projects based on information entropy and grey relevant analysis

工程评标是工程招投标活动的关键环节,其方法是否科学合理决定了招标方是否能够选出最合适的施工单位,从而也决定了工程是否能够顺利建设完成和运营,并最终取得期望的经济效益和社会效益。应用信息熵客观地确定评价指标的权重,同时利用灰色关联分析理论解决贫信息问题,在此基础上建立了基于信息熵和灰色关联度的工程评标模型,使得评价结果更加客观,更符合实际。通过实例运用表明,该模型具有一定的可操作性和推广应用价值。

Bid evaluation of construction projects is a key part in the bidding of construction pro- jects, which determines the choosing of the proper constructor, the completion of the project and the realization of the eventual economical and social benefits. Weight of evaluation index is determined via information entropy. Inadequate （poor） data information is solved in terms of grey relevant ana- lysis theory. A bid evaluation model of construction projects is established based on information en- tropy and grey relevant analysis. Practical evaluation results indicate that the model is feasible and practicable.
