水资源系统模拟中的自优化问题

The selfoptimization of water resources systems simulation

水资源系统由于自身复杂性，数学规划方法难以推广，而模拟方法在许多领域得到成功应用。根据近年来人们期望模拟模型具有自优化功能的思路，提出一种模拟自优化的新方法，即根据控制论的反馈原理和方法，在模拟中引入反馈系统，通过对它的调整实现模拟模型自优化。实际应用表明反馈自优化方法大大扩展了模拟方法的功能，能够推广应用于水资源系统的其他领域。

ecause of the complexities of water resources systems,mathematical programming optimization techniques can not be widely useful,but simulation models have been successfully used.by various practitioners.Recently,it would be desirable for the simulation model to have some capability of selfoptimization.On the basis of feedback control theory and method,this paper presents a new method of selfoptimization,which incoporates optimization into simulation.The application shows the feedback selfoptimization method has improved greatly simulation function and can be used widely in the other fields of water resources systems.
