应用多目标多功能模糊模型优选水利枢纽工程参数

本文应用系统工程的观点与概念，论述枢纽工程系统是河流系统的子系统，是流域系统的子子系统。在治理开发，利用该系统的水利水能资源时，需满足多目标多功能综合效益整体最优与总费用最小的要求；规划设计中所用的比较方案或替代方案与原方案应基本等价，使他们具有可比性的基础。为了确切反映多目标多功能整体最优，运用了多因素模糊综合评判的理论与方法来优选枢纽工程在数。为使选择正常蓄水位所用数据具有一定的理论依据，首先

Selecting optimal Parameters for Water Conservancy Projects by Means of a Multiobjective and Multipurpose Fuzzy Model

According to the Theory of system engineering,a water conservency project system is a subsystem of the river system and a sub-subsystem of the river basin.The global optimization must be satisfied with the comprehensive efficiency of the multiple objective and multiple purpose and the total cost minimum for improvement,development and utilization of water resources in the water preject.All the comparative or alternaive schemes must be basically equal in value with the primary scheme during the planning design process.Therefor,for the sake of achieving the global optimization of the multiple objective and multiple purpose,not of the dividual objective and purpose,we must use the theory and method of the Fuzzy multifactor synthetic judgment to the selection of water conservancy project parameters.It is advisable that,first of all,we must select an optimal dead storage level for a given normal water level,then,an optimal normal reservoir level will be determined.An illustrative example is given and the results o calculation are in agreement will the prime design on the whole.
