《江苏水利科技》八七年第一期,发表了摹矩阵在水利工程技术中的应用,它是将矩阵的概念加以推广和扩充建立一套适用于多阶段决策问题的运算规则,利用摹矩阵的摹乘积来获得问题的最优的结果。本文则参照网络方法的思路和图论中的知识提出解决多阶段决策问题的另一种演算方法。这种方法称之为结点标记推算法,比摹矩阵方法更加简单,更容易掌握,更便于推广应用。
The first phase of “Jiangsu Water Conservancy Science and Technology” published in 1987 the application of G matrix in water conservancy engineering. It extends the concept of matrix and expands it to establish a set of arithmetic rules applicable to multi-stage decision-making. Using G matrix Of the product of G to get the best result of the problem. In this paper, another approach to solving multi-stage decision-making problems is put forward according to the idea of network method and knowledge in graph theory. This method is called the knot mark extrapolation method, which is simpler and easier to grasp than the matrix method, which is more convenient to popularize and apply.
