摘要:

针对方案区分度(方案综合评价值之间的差异性)较低而导致难以有效决策问题,将主观权重与客观权重作为样本点,采用规划方法建立组合赋权优化模型。基于统计学相关原理,提出了组合权重信度概念,分析了其对决策结果的影响,给出了信度判别准则。以方案区分度较快改善为目标,提出了组合权重修正的具体步骤。最后运用民营企业进入军品市场的算例说明方法的有效性。

Abstract:

According to ineffective decision-making problem developed by low alternative discrimination which is depicted as lower value among evaluation results of multi-alternative than given in advance, by applying programming idea, the paper proposes an optimal weighting model based on the sample points of the subjective weight offered by decision-makers and objective weight calculated by decision-matrix. Based on statics theorem, the reliability of combination weight is given, and its relative effect is also analyzed, so the paper supposes some rules of distinguishing them. In order to realize the object of improving alternative discrimination quickly, specific weight modification steps would be offered based on the above analysis. Finally, an example of private-owned enterprises gaining certification of military market is introduced to explain the process of the method.
