项目摘要

The sustainable development in water resources must handle all of feasible purposes as municipal use, industrial use, agriculture use, recreation, water level of reservoir, hydro power, ecology, fishery, ant so on. Then we define the planning purpose as minimizing the fuzzy grade where each one is represented with fuzzy membership function.Assuming the uncertain future water discharge and water demand due to global warming and population increase until 2100, we formulated the fuzzy linear optimization problem to maximize the fuzzy grade. The necessary capacities of reservoirs and pipelines can be decided with high grade of membership functions.Then the construction schedule of systems were formulated by using fuzzy dynamic programming. The objective was to minimize the total difference between water demand and supply under the condition of changeable water discharge and water demand at considered time stages. The state and decision variable in DP was represented as the combination of considerable facilities with numerical values of 0 and 1.The water quality for environmental investigation was analyzed with box-typed run-off and fetal prediction model.For the design operation with few monitoring data in the mountain regions, the run-off discharge was estimated by using the uncertain information such as reputation and human sense with fuzzy theory. The reservoir was controlled with uncertain input and fuzzy dynamic programming, too.

水资源的可持续发展必须处理好城市用途、工业用途、农业用途、游憩用途、水库水位、水电、生态、渔业、蚂蚁等各种可行用途。然后将规划目标定义为最小化模糊等级，每个模糊等级用模糊隶属度函数表示，假设到2100年，由于全球变暖和人口增加而导致的未来水量和用水需求不确定，我们建立了模糊线性优化问题，以最大化模糊等级。用隶属度高的函数确定水库和管道所需的库容，然后用模糊动态规划法确定系统的施工进度。目标是在考虑的时间阶段变化的水量和需水量的情况下，最小化供需之间的总差值。将DP中的状态和决策变量表示为大量设施的组合，数值为0和1。采用盒式径流和胎儿预测模型对环境调查水质进行分析；对于山区监测数据较少的设计调度，采用模糊理论，利用声誉、人情等不确定信息进行径流流量估算。对水库进行了不确定输入和模糊动态规划控制。
