基于粒子群优化算法的水分配网络系统综合的最优化研究(英文)

The problem of optimal synthesis of an integrated water system is addressed in this study, where water using processes and water treatment operations are combined into a single network such that the total cost of fresh water and wastewater treatment is globally minimized. A superstructure that incorporates all feasible design alterna-tives for wastewater treatment, reuse and recycle, is synthesized with a non-linear programming model. An evolu-tionary approach—an improved particle swarm optimization is proposed for optimizing such systems. Two simple examples are presented to illustrate the global optimization of integrated water networks using the proposed algorithm.
