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。 Due to its complexity, water resources system is difficult to popularize mathematical programming methods, and simulation methods have been successfully applied in many fields. According to the expectation that the simulation model has the function of self-optimization in recent years, a new method of simulation self-optimization is proposed. According to the feedback theory and method of control theory, a feedback system is introduced into the simulation. optimization. The practical application shows that the feedback self-optimization method greatly expands the function of the simulation method and can be widely applied in other fields of water resources system.
