摘要
政府工程采购在政府采购中的份额达60%以上,考虑政府工程采购过程中评标的重要性及评价过程本身具有的不确定性和复杂性,提出了构建基于灰色理论的政府工程采购灰靶评标模型。将决策目标下的各个指标值集结为目标综合效果评价值,分别定义正、负靶心,计算各评价对象到正、负靶心的距离,通过空间投影分析计算各方案的综合靶心距,再以综合靶心距最小准则构建目标规划模型,得到各个目标的权重。构建的灰靶评标模型扩展了灰靶决策方法的应用领域,是对政府工程采购评标方法的一次有益尝试。实例分析验证了该模型在政府市政工程采购评标实际应用中的有效性和科学性。
Government project procurement accounts for more than 60% share in government procurement.Considering the importance of the evaluation in government project procurement process and the uncertainty and complexity of evaluation itself,this paper proposes government project procurement gray target evaluation model based on gray theory.First,each index value under the decision goal is combined as effect of the evaluation value for the target assembly;then,the positive and negative bull＇s-eyes are defined,the distances of the evaluation objects to the positive and negative bull＇s-eyes are calculated,and the integrated clout＇s distance of each program is obtained;finally,the goal programming model is constructed based on the minimum integrated clout＇s distance,and each target weight is obtained.The gray target evaluation model expands the application fields of gray target decision-making process,and can be a useful attempt to government procurement project evaluation methods.The case study also verifies that the model is effective and scientific in practical government municipal project procurement.
