| 摘 要： | 作为多目标决策中的一种后最优性分析，参数敏感性分析已经得到越来越多的重视而成为决策中的一个重要步骤．通过引入权重最小变化量和敏感性系数等概念，研究了多目标决策中权重变化导致结果变化的临界条件，给出了方案排序对权重变化的敏感性分析方法，并通过一个实例来进行说明．

| Abstract: | As a post-optimization analysis in multi-objective decision-making, analysis of the parameters sensitivity has been paid more and more attention and become an important step of decision-making. In this paper, the critical condition that weights variation result in ranking results change in multi-objective decision-making were studied by introducing the concept of the least variance of weights, sensitivity coefficients, etc..And a weights sensitivity analysis method is proposed..A numeral example is used to illuminate the approach proposed by this paper. |
