基于熵的灰关联模型在工程评标中的应用

Application of gray relationship model basing on entropy onconstruction engineering bid evaluation

针对建设工程评标中投标信息不全是明朗的这一现象,为消除评价指标确定权重时的主观影响和选择最接近业主理想承包商的投标单位,构建基于熵权的灰色关联度决策模型用于工程评标过程中。应用熵权法确定评标指标体系中各指标权重,灰色关联方法用于投标单位与业主理想承包商的关联程度,关联度值大的表明投标单位与理想承包商越接近,越符合业主的施工要求。结果表明:结合熵权重的加权关联度的计算应用于工程评标,使得评标结果更加客观,符合实际,为业主评标定标提供了定量决策依据,同时利于招标单位更合理、准确的选择承包单位。

Bidding information is not all clear in the construction project bid evaluation. In order to eliminate the evaluation index to determine the weight of the subjective influence and select the most close to the owners of the ideal contractor bid unit, grey related degree model for engineering bidding evaluation was proposed based on the entropy weight. The index weight of evaluation index system was determined by application of entropy method, grey correlation method was applied to determine contractors＇ association degree between bidding units and the owner＇ s ideal. The great association degree indicatesthat bidding units is line with contracting business approach and the owners of the construction requirements. The results show that the combination of entropy weight correlation calculation is applied to the engineering bid evaluation, which makes evaluation result more objective, practicalfor the owners to demarcate mark and provides a quantitative basis for decision making, while it is beneficial for the unit to choose reasonable contractors.
