摘      要：In Vietnam as well as many countries which apply the irrigated agriculture over the world, the process of promoting thesocialization trend in irrigation for the basic irrigation organizations, of which the main factor is water users, is very important. Thispaper aimed to optimize the decentralization of management and exploitation of irrigation works for water users, organizations inQuan Lo-Phung Hiep irrigation system of Mekong River Delta. The research has implemented a survey on 384 water users alongfour canals of level 2 of Quan Lo-Phung Hiep irrigation system under two sets of index： （1） water users＇ perception assessment of theirrigation works （14 indicators） and （2） assessment of the management efficiency in the irrigation works （six indicators）. Theresearch proposes the decentralization process from building, After determining the correlation coefficients, the multi-objective linearregression equation will be shown on six single objective functions. With the aim at achieving the highest efficiency in themanagement and exploitation of the irrigation works, there should be a shift in terms of the water users＇ perception of the irrigationworks. These study results also demonstrate that about 65%-68% of the change in the indicators of the exploitation efficiency in theirrigation works is explained by some water users＇ perception indexes of irrigation works, including the quality of irrigation service andthe output efficiency in agricultural production. By using the algorithm for multi-objective optimization problem, the optimal results inperception are determined. The input data is generated for the matrix supporting the decision making, and the decentralization ofmanagement and exploitation of irrigation works meets the three criteria, i.e., effectiveness, sustainability and flexibility.
