基于改进SPEA2算法的给水管网多目标优化设计
Multi-objective optimization design of water distribution systems based on improved SPEA2 algorithm
摘要
Abstract
To solve the multi-objective optimization problem in water distribution system design, we consider three ob-jective functions-the cost of the pipe network and the sum and variance of the node surplus head. Then, we optimize the water distribution system in terms of economy and reliability. To obtain well-diversified and well-convergent solutions, we combine the concepts of domination and decomposition and introduce reference vectors into the Strength Pareto Evolutionary Algorithm 2 (SPEA2). The diversity and convergence of the algorithm are increased by the use of the dom-ination strength-based solutions selection method. We use the proposed algorithm to optimize the two-loop network and the New York Tunnels network, and the simulation results demonstrate its effectiveness in realizing the multi-objective optimization of water distribution systems design. Finally, we apply the algorithm to actual pipe network construction.关键词
