Study on digraph of tree length measuring design

Abstract

Rational measuring design of the tree length is a course to optimize all position of it before bucking. This paper offers the weighted digraph in the digrams and theories to solve the optimal problem of rational measuring of tree length based on experts’ researches in home and foreign. Sawlines are defined as apexes x_d, log between two sawlines as a side y_n, the price of log as weight W_ij. It can describe the digraph of the rational measuring design of the tree length T = (X, Y, W_ij), which consists of point-set and side-set. Oweing to W_ij> 0, using Mr. E. W. Dijkstra’s theory, we can obtain the “path” of maximum profit of the tree length under the best availability of the tree length.
