Research on Hedging Rules Based on Water Supply Priority and Benefit Loss of Water Shortage—A Case Study of Tianjin, China

摘要: When a city’s water demand cannot be fully satisfied, the hedging rule can reduce loss by limiting supply in advance. Based on priority and benefit of shortage for different users, this paper improved objective function rules considering shortage. At same time, according to idea restricting users turn, (IHR) are applied urban Tianjin. The conclusions achieved from study as follows: (1) IHR increased assurance rates domestic with high-priority avoided destructive shortages agricultural low-priority. (2) better caused large number production small numbers than traditional rules, which ensures high efficiency during dry period. results show that improve operational performance supply.
