本文研究了多目标决策中线性加权法加权因子的确定方法。该方法以各分目标建立设计空间，以形心和重心做为统一目标函数的中心，从而确定了基于中心点至各分目标最优点间距离上的规格化加权方法。 This paper studies the method of determining the weighting factors of linear weighting in multi-objective decision making. The method establishes the design space with each sub-target, and uses the centroid and center of gravity as the center of the unified objective function, thereby determining the normalized weighting method based on the distance between the center point and the sub-targets.
