ABSTRACT
Water scarcity poses a real crisis for decision makers of water supply system because satisfying growing demand and, as a result, achieving full consumer satisfaction in different sectors of the system remains a major problem. Therefore, this study develops a dynamic multi-objective model of water supply optimization under different scenarios to improve multisectoral consumer satisfaction. To diminish the negative effects of the water crisis on long-term consumer satisfaction, the performance of the dynamic water supply system is evaluated and optimized, which can change the situation from a state of dissatisfaction to satisfaction. In this regard, to analyze the developed model, a real case study of the Hamoun wetland in southeastern Iran is considered. According to the proposed model, various strategies are performed along with the analysis of two scenarios related to runoff uncertainty in order to investigate the consumer satisfaction status in detail. However, given to the final results, which show the greater impact of the two sensitive factors of reliability and vulnerability on consumer satisfaction, the highest level of dissatisfaction is related to the agricultural sector because it has less reliability and higher vulnerability compared to other sectors. In this regard, by proposing policies such as weight scenarios and demand reduction scheme, the situation of consumer satisfaction has improved much more desirable.
