Abstract: Optimal allocation of water resources (OAWR) is a constrained multi-objective optimisation problem, which aims to allocate limited water resources to different water-use departments and maximise the economic, social, and environmental benefits. Multi-objective evolutionary algorithm based on decomposition (MOEA/D) is a well-known multi-objective optimisation algorithm, which has shown excellent performance on various benchmark and practical problems. In this paper, we try to use MOEA/D to solve the OAWR problem with two objectives and multiple constraints. A normalised method is used to handle the equality constraint. To deal with inequality constraints, a penalty strategy is employed. Simulation results show that our approach can obtain good spacing of solution points along the Pareto front. According to the preferences, the decision makers can choose different allocation strategies from the Pareto front.
