【摘要】：针对多目标非劣解集非凸时均衡解不唯一的问题,本文将均变率法和逼近理想点法耦合,形成一种新的多目标决策方法—理想均变率法,同时对该方法的最佳均衡解的存在性及唯一性进行了严格的理论证明。以雅砻江流域锦官电源组的多目标调度决策为例,分别对均变率法、逼近理想点法和理想均变率法进行了分析比较。结果表明理想均变率法不仅能得到满足多目标调度需求的最满意方案,而且可以定性、定量地描述防洪、发电与生态三目标间的相互转换关系。该方法理论证明完备,且兼顾冒险型和保守型的决策方式,在实际工作中更易被决策者接受,为多目标决策提供了一种新的有效的方法。
[Abstract]:In order to solve the problem that the non-convex equilibrium solution of multi-objective noninferior solution set is not unique, a new multi-objective decision method, ideal average variable rate method, is formed by coupling the mean variable rate method and the approximate ideal point method. At the same time, the existence and uniqueness of the optimal equilibrium solution of the method are proved in strict theory. Taking the multi-objective dispatching decision of the Jinguan power supply group in the Yalong River basin as an example, the average variable rate method is used respectively. The results show that the ideal average rate method can not only obtain the most satisfactory scheme to meet the needs of multi-objective operation, but also can describe the flood control qualitatively and quantitatively. This method has been proved to be complete in theory and has been accepted by decision makers in practical work by taking both risk and conservative types into account. It provides a new and effective method for multi-objective decision making.
