本文提出了大系统多目标递阶分析的一种非劣解生成技术——“分解-聚合”方法。这种方法不仅可以在大系统多目标决策分析时生成非劣集或子集,而且具有对主要决策变量进行敏感性分析等功能。这种方法既适用于确定性大系统,又可用于随机大系统。本文后半部分还以丹江口水库运行中两对矛盾的多目标风险分析“实例来具体说明方法的使用。
In this paper, we propose a non-inferior solution generation technique for multi-objective hierarchical analysis of large systems - the ”decomposition-aggregation" approach. This method can not only generate non-inferior sets or subsets in multi-objective decision analysis of large-scale systems, but also has the functions of sensitivity analysis on the main decision variables. This method is suitable for both deterministic and stochastic systems. The second half of this article also uses two pairs of contradictory multi-objective risk analysis in Danjiangkou reservoir operation to illustrate the use of the method.
