Improvement of technological solutions of wood processing based on cybernetics and automation methods

Abstract

The urgency of the task of rational wood processing is, on the one hand, a shortage of timber resources and, on the other hand, an increase in consumer demand for the nomenclature of forest products in conditions of the preservation of a normal ecological situation. Resource conservation is possible under the condition of proper operations, ranging from felling of trees and ending with bucking of logs and the production of other wood products. Among the measures aimed at the effective use of wood of round wood in the conditions of the modern market, one of the main ones is the optimal cutting of logs. The purpose of this study was to develop a method and algorithm for maximizing a cylindrical volume during dumping by identifying the optimal pattern of cutting a whip by the method of successive approximations to the optimal solution. The whip model is justified and the input parameters are listed. Taking into account the limitation of the cutting zone and the possible number of logs, the procedure for forming trial cutting patterns and the principle of choosing the optimal scheme are described. The presented algorithm reduces the number of calculations by orders of magnitude compared with the sequential enumeration of all possible options for cutting, so it can be considered as one of the links of promising systems for automated management of the process of bucking and accounting of timber volumes.
