Abstract
Complexity of engineering problems, especially in the field of water resources, makes traditional optimization tools less efficient and enhances the popularity of evolutionary algorithms. Traditional optimization methods present just a single point as the optimal solution even in multi-objective problems. Thus, the main necessity to apply evolutionary algorithms is to present a set of nondominated solutions/Pareto-fronts as the optimal/near-optimal solutions, whereas most of problems in the field of water resources management are considered as a compromise between several objectives. In this paper, the Multi-Objective Particle Swarm Optimization (MOPSO) is applied to the operation of a multipurpose reservoir system. The objectives are: (1) maximization of reliability; (2) minimization of vulnerability; and (3) minimization of resiliency of the reservoir system, satisfying the downstream demand. The proposed algorithm is compared to a traditional method (weighting method). Results show that the MOPSO algorithm is successful in finding near-optimal, Pareto-front solutions.
