Interoperational preparatory works in through processes of forest logging

A set of credible ways increasing productive efficiency of the forest logging process by means of optimization of interoperational methods are presented in the article. The operation of each machine enabled in the chain process of forest logging consists of the main and additional methods. The main methods are those that are obligatory to execute in order to reach the goal of the operation. The additional methods are those that are intended to increase efficiency of either the machine under consideration or the following machine employed in the through process of forest work. The article gives examples of the main and additional methods for the through process of short log operations by the system of machines represented by a harvester and a forwarder. Modeling of each method from the main and additional groups will allow receiving recommendations on the most optimal organization of the whole technological process of forest logging works.
