在水资源规划利用中,经常要遇到供水量分配优化和工程投资等问题,这些都属于动态规划的范畴,是一个多阶段的决策最优化问题。这类问题的一般解法是:首先建立动态转移方程,再根据贝尔曼最优化原理,把问题分成若干阶段,分段寻优找出各个阶段的最优的结果。这种方法要用到较深数学知识,动态转移方程不容易建立,因而使其推广和应用受到很大的限制,影响了它的实用价值。本文介绍的表格纸带对位计算法,则是把复杂的数学模型转化成表格纸带的形式,避开了建立动态转移方程的难点,使其计算方便简捷,操作简单
In the planning and utilization of water resources, we often encounter such problems as the optimization of water supply allocation and project investment. All these belong to the category of dynamic programming and are a multi-stage decision optimization problem. The general solution of this kind of problem is as follows: Firstly, the dynamic transfer equation is established, then the problem is divided into several stages according to the Bellem optimization principle, and the optimal result of each stage is found by sub-optimization. This method requires deep mathematical knowledge, dynamic transfer equation is not easy to establish, thus its promotion and application are greatly limited, affecting its practical value. In this paper, the table paper tape alignment method is to transform the complex mathematical model into the form of paper form, avoiding the difficulty of establishing dynamic transfer equation, making it easy to calculate and simple to operate
