A Method of Multi-Objective Optimization and Multi-Attribute Decision-Making for Huangjinxia Reservoir

The objectives of flood control, power generation, water supply and ecology for reservoir operation are neither completely coordinated nor opposed, its optimal decision-making is very complicated. This study proposed a method multi-objective optimization multi-attribute decision making (MODRO). correlation analysis was used to analyze the competitive relationship among extracted objectives, model constructed. NSGA-II-SEABODE algorithm applied solve MODRO problem. objective extraction, construction, solution scheme selection were coupled form with whole process “Objective-Modeling-Optimization-Selection”. Huangjinxia Reservoir, which located in Shaanxi, China, selected as case study. results show that: (1) Quantifying degree conflict makes construction more reasonable. (2) obtain scheme, provides basis managers. (3) For diversion negatively related generation ecology, positively ecology. can promote efficient utilization resources, improve comprehensive benefits reservoirs, provide support actual operation.
