Preface With the social and economic development, rapid population growth, the contradiction between supply and demand of water in many regions has become increasingly prominent, and water quality has been deteriorating. These factors have increasingly shown the restrictive effect on the economic and social development in these regions. To this end, various localities and departments concerned have proposed various measures and programs in various aspects such as opening up, saving money, water management, water pricing and protection of water bodies in order to solve this problem. How to systematically and scientifically evaluate these programs, select the best programs and determine the optimization order of various programs are the problems that this paper tries to solve.
