عنوان مقاله [English]
Today, water scarcity has become one of the most important concerns of the country's agricultural sector, a problem that has affected not only the agricultural sector, but also the industrial sector and even the drinking sector in some parts of the country. In recent years, following climate change, population growth and increasing needs, the method of water distribution is expected to change and redistribution to be seriously considered. The irrigation network of Qazvin plain was about 255 million cubic meters per year at the beginning of its establishment, but in recent years, the water allocated to this network has decreased to about 120 million cubic meters per year. Due to this sharp decline, there has been no change in the network's stakeholder allocation program and the ratios allocated to them are the same as before. In this research, using fuzzy multi-objective optimization method, the optimal redistribution of water among the stakeholders of Qazvin plain irrigation network has been done with the aim of increasing the utility of the whole system, including increasing the income of users and
equity in distribution. The results showed that after redistributing water according to the proposed method, the total revenue of the network increased by 40.7% and the justice index reached 54.5%.
