An interval-parameter multiobjective programming model for waterresources management with an interactive algorithm

摘要

Water shortage emerges and restricts the urban construction and the socio-economy development due to the rapid expansion of the cities throughout the world. A practical water resources system has complexities among social-economy, natural resources, and environment, which leads to multi-objective and significant uncertainties exist in system parameters, objectives, and their interactions. A number of optimization methods have been proposed for supporting system planning under uncertainty and multi-objective. As an extension of the previous efforts, an interval-parameter multi-objective programming model will be developed and an interactive compromising solving algorithm will be introduced. Through interactive compromising conflicts among multi-objectives, a feasible solution can be obtained. The developed model has been applied to allocate multi-source water with different water qualities to multi-users with different water quality requirements for the Dalian City in China, where water resources shortage is a challenging issue. The results indicate that the allocation of multi-source water for multi-user is more reasonable and efficiency.
