1 引言在有限方案多目标决策方法中,确定各分目标权重是一个关键的问题。对各指标赋权的合理与否,直接关系到分析结论的可靠性。确定权重的方法主要分为主观赋权法和客观赋权法两类。主观赋权法是由评价者根据对各项评价指标的主观重视程度而赋权的一类方法,常用的有专家调查法、二元比较法、层次分析法等,无论是其中的哪一种,都是基于各项指标重要性的主观认知程度,不可避免地带有一定的主观随意性。客观赋权法是利用评价指标所反映的客观信息确定权重的一种方法,
1 Introduction In the multi-objective decision-making approach of finite programs, determining the weight of each sub-goal is a key issue. The rationality of each indicator weighting is directly related to the reliability of the analysis conclusion. The method of determining the weight is mainly divided into two types: subjective weighting and objective weighting. Subjective empowerment method is a kind of method that the evaluator empowers according to the subjective importance of each evaluation index. There is commonly used expert investigation method, binary comparison method, AHP, etc., no matter which one , Are based on the subjective cognition of the importance of each index, inevitably with a certain degree of subjectivity and arbitrariness. The objective weighting method is a method of using the objective information reflected in the evaluation index to determine the weight.
