针对水库多目标调度模型生成的众多Pareto可行解,决策者往往面临方案优选决策困难的问题。提出利用可视化展示工具,结合边际效益分析及模糊优选方法,对可行方案进行逐步决策的优选决策方法。结果表明,利用不同的分析工具与决策方法,使众多可行方案得到形象可视化展示的同时,能够融入决策者的主观偏好等信息,得到具有不同决策需求的满意方案。通过不同决策方法的层层决策,逐渐减少备选方案的数量,降低了多目标决策问题的复杂性,为决策者的方案优选提供一定的参考。
In view of many Pareto feasible solutions generated by the reservoir multi-objective scheduling model, decision-makers often face the problem of difficult decision making. This paper proposes a method of decision-making for the step-by-step decision-making of feasible solutions by means of visual display tools, combined with marginal benefit analysis and fuzzy optimization methods. The results show that, with the help of different analysis tools and decision methods, many feasible solutions can be visualized and visualized. At the same time, this method can incorporate the subjective preferences of decision-makers and so on, and get satisfactory solutions with different decision-making needs. Through the decision-making at different levels, the number of alternatives is gradually reduced, the complexity of the multi-objective decision-making problem is reduced, and a certain reference is provided for the decision makers’ optimization.
