基于模糊综合评价法的综合单价风险量化
发布时间：2018-09-19 06:45
【摘要】：自实行工程量清单计价模式以来,投标人的报价风险费用隐含在工程量清单的综合单价中,综合单价的合理确定显得尤为重要。本文根据综合单价的组成对综合单价的风险因素进行了分析,将三角模糊数引入层次分析法中构建风险因素的判断矩阵,求出风险因素的权重,利用模糊综合评价的方法求出风险费用系数,根据投标人的预期利润率得到综合单价的综合风险系数。结合南京市某保障房项目对建立的模型进行算例分析,确定出符合项目特点和投标人实力的综合单价的综合风险系数。
[Abstract]:Since the implementation of the bill of quantities pricing model, the bidder's quotation risk cost is implied in the comprehensive unit price of the bill of quantities, and the reasonable determination of the comprehensive unit price is particularly important. In this paper, the risk factors of comprehensive unit price are analyzed according to the composition of comprehensive unit price. The triangular fuzzy number is introduced into AHP to construct the judgment matrix of risk factor, and the weight of risk factor is obtained. The risk cost coefficient is calculated by using fuzzy comprehensive evaluation method, and the comprehensive risk coefficient of the comprehensive unit price is obtained according to the expected profit rate of the bidder. Combined with an example of a indemnificatory apartment project in Nanjing, the comprehensive risk coefficient of the comprehensive unit price, which accords with the characteristics of the project and the strength of the bidder, is determined.
