摘 要: 多属性决策的各指标赋权是决策的重要环节.当环境改变时,决策的指标数有可能变化.如何较简便地给出环境改变后指标的权值,是决策分析的一个重要研究内容.本文在文献[1]G1赋权法的基础上给出指标增减时的权重修正公式. The weighting of indices is very important during the multi-attribute decision-making.The number of indices may be verified when the decisive environment is transformed.How to endow weight with the indices after the transformed environment is an important task to study in the decision-making synthesis.This paper proposes several modified formulas which are based on the G1 method in [1] after the indices changed.
