摘　　要：为了有效描述和求解跨流域水库群最优调供水过程,本文建立了基于0-1规划方法的水库群最优化调度模型,统一考虑并最终确定了最优调供水过程。为减少模型单次求解的变量数目,同时增加算法全局搜索的能力,本文借用逐步优化算法思想,对传统粒子群进行改进,提出了逐步优化粒子群算法(PRA-PSO)对模型进行求解。最后,通过中国北方某大型跨流域调水工程的实例研究分析了模型的合理性和有效性。最优调供水过程的确定不仅可为采用隐随机优化方法确定跨流域水库群调水规则和供水规则提供最优化样本过程,而且对跨流域调水工程调度运行评价具有重要意义。For delineating and solving water transfer and supply processes of inter-basin water-transfermulti-reservoir system,the 0-1 programming method is employed in this study to determine the optimal wa-ter-supply and water-transfer progress,which need to be considered together in the joint operation process.For reducing decision variables in single optimization and improving the global search ability,the principleof Progressive Optimization Algorithm is adopted to develop the traditional Particle Swarm Optimization algo-rithm into a Progressive Reservoir Algorithm-Particle Swarm Optimization（PRA-PSO） to solve the optimiza-tion model. Finally,an inter-basin water transfer project in North China is taken as the case study to veri-fy the reasonability and efficacy of the model. The optimal operation process not only can provide the datasamples for stochastic optimization operation, but also can be used to evaluate the operation result ofmulti-reservoir system.
