基于熵的灰关联模型在工程评标中的应用

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.

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

On the phenomenon of 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 selection of the most close to the owners of the ideal contractor bid unit, refers to the gray relational degree of decision-making model based on entropy weight, application of entropy to determine the weight of each index, the calculation of the Weighted Association for the Evaluation and Determination of the quantitative basis for decision making , making the tender side more reasonable select construction unit.
