针对采用常用的投标决策方法未能有效地解决影响因素、影响因素与决策结果之间的复杂非线性关系问题,基于《水利水电工程标准施工招标文件》(2009年版)合同通用条款,结合我国当前水利工程建筑市场的竞争情况,构建了基于BP神经网络的水利工程投标决策模型,并将其应用于工程实例中。结果表明,该模型实用、可行,能有效应用于承包商的投标决策中。 Aiming at the problem that the common bidding decision-making method can not effectively solve the complex nonlinear relationship between the influencing factors, the influencing factors and the decision-making results, based on the general terms of the contract of the Bidding Documents for Water Conservancy and Hydropower Engineering Standards (2009 Edition) Water conservancy project construction market competition, the construction of a water project bidding decision-making model based on BP neural network and its application in engineering examples. The results show that the model is practical and feasible and can be effectively applied to the contractor’s bidding decision.
