摘要
针对实现江湖两利的长江中游健康江湖关系水库群优化调度需求,以洞庭湖健康、鄱阳湖健康及水库蓄水为目标建立了健康江湖关系的长江中游水库群多目标优化调度模型。提出了一种改进的多目标猫群算法(IMCSO),该算法通过引入外部归档集来储存进化过程中的精英个体,并对结合率进行改进,同时设计了精英变异策略防止算法陷入局部解。通过IMCSO算法对模型进行高效求解,得到不同偏好下的水库群联合调度方案。同时,构造了一种适用于系统方案优选的基于主观偏好和改进熵权的Vague集多属性决策方法。该方法通过多属性决策中专家群体偏好的集结,得到了综合反映专家群体主观偏好的主观权重向量,并结合改进熵权法计算出的客观权重可得到综合权重,最后根据所提出的排序函数对各方案的综合Vague值进行打分,获得方案的优劣排序。实例研究表明,所提出的方法合理有效,具有较强的工程实用性,可为改善长江中游洞庭湖和鄱阳湖的生态环境提供理论依据。
An improved multi-objective Cat Swarm Optimization（IMCSO） cat is proposed to improve the combination ratio while the design elite mutation strategy prevents algorithm from entering local solution through IMCSO algorithm to solve the model effectively. At the same time,a suitable system optimization is constructed based on subjective preferences and the entropy weight of Vague set multiple attribute decision-making method has been improved. The comprehensive reflection expert group subjective preference subjective weight vector,and combining the improved entropy method of calculating the objective weight of comprehensive weight can be obtained. According to the proposed sorting function comprehensive Vague values of each scheme. The solution shows that the presented method is reasonable,effective and highly practicable. It can improve the ecological environment of Dongting Lake and Poyang Lake in the middle reaches of the Changjiang River.
