Графоаналитическое моделирование технологии поквартального освоения лесосек в нечетких динамических природно-производственных условиях

Abstract

В статье предложены принципы построения и расчета растянутых во времени графоаналитических мо-делей операционной сети, позволяющие обосновать последовательность освоения лесосек и выполнения технологических операций в нечетких динамических природно-производственных условиях освоения лесного квартала, сократить технологические простои и повысить эффективность лесозаготовительных работ предприятия. Для решения предложенной графоаналитической модели разработан алгоритм по-иска потока минимальной стоимости, обоснования величины характерных для него затрат и расчета максимальных пропускных способностей путей между фиктивным источником и стоком в структуре предложенных графических моделей. Модель отличается комплексным учетом двух основных характе-ристик технологического процесса лесосечных работ: производительности и трудозатрат, представлен-ных в качестве пропускных способностей дуг графа.

In this paper proposed the principles and calculations of stretched in time graphic-analytical models of the oper-ating network. They allow you to determine the sequence of logging operations at logging sites within the forest compartment, to reduce nonmechanical delay and increase technological efficiency of harvesting operations with fuzzy dynamic natural-production conditions. Search algorithm minimal cost flow developed to solve the pro-posed graphic-analytical model. It allows justifying the amount of expenses and calculating a maximum band-width of arcs between the fictitious source and drain of graphical model. The model differs complex use of two main characteristics of the process of logging operations: productivity and labor costs presented as individual capacities of graph arcs.
