一、应用动态规划确定林分最佳密度一个整体系统的最佳决策往往包括几个阶段的决策。动态规划就是通过多阶段决策最终使整体系统达到最佳状态的一种数学方法。动态规划用来决策林分密度时,按其基本原理,将林分生长过程划成几个阶段,确定状态变量和决策变量,以及目标函数,然后据此建立求解最佳方案的递推方程。
First, the application of dynamic planning to determine the optimal density of the forest The best decision-making of an overall system often includes several stages of decision-making. Dynamic planning is a mathematical approach that ultimately leads to the best overall system through multi-stage decision making. When the dynamic programming is used to determine the stand density, according to its basic principle, the stand growth process is divided into several stages, the state variables and decision variables and the objective function are determined, and then the recursion equation for solving the optimal plan is established.
