Title: Study on Water Engineering based on Mathematical Models
Abstract: Fresh water is the limiting constraint for development in much of the world.As we know, China is a water-shortage country, where the water available for each person is only a quarter of the world's average level.Author put forward five water strategies to help the government meeting the water demands in the future.First, a water transport and storage model is proposed to cope with the unbalanced distribution of water resources, in which fuzzy optimization approach is taken to achieve the water allocation.A case study shows Tianjin has the largest amount of water rights within the four cities.Then, a Sewage Treatment Plant Location optimization model, which considers environment protection, the total investment, the local governmental planning, and the operation costs simultaneously, is established.A hybrid genetic algorithm with simulated annealing strategy in the generation gap is employed to solve the proposed model.
