RESULTS OF STUDIES OF CHANGES IN OPERATING STOCKS OF WOOD IN THE PROCESS OF LOGGING OPERATIONS
The technological process of harvesting is the amount of operations performed in a specific sequence between which stockpiling of trees (longwoods, assortments) is required. In order to study the nature of changes in inventories and methods of operative management experimental studies were made. The studies were conducted by field observations of the work of machines in operations: roll-packaging (one ЛП-19), delimbing (two ЛП-33A), skidding (two ЛП-18, one ЛТ-154) and the change in inventory levels between adjacent operations in conditions of the Kirov and the Bryansk regions. Statistical data processing was carried out by methods of mathematical statistics. Analysis of the data showed that to find the number of the machine so that the volume of their production at all operations was the same is almost impossible. Usually either harvester (wood felling and packaging) machines are ahead, and on the cutting area there is impossibly large amount of felled trees, or skidding tractors do not have enough wood, and they begin to stand idle, followed by the stand idle of delimbing machines. To reduce downtime and increase production of sets of machines to a volume of the leading machine, it was decided to use the additional machines at lagging operations. Analysis of industrial research has given us the opportunity to prove the character of changes in inventories and prove the need to increase the number of equipment (setting extra equipment) and / or the number of shifts of the machines on the lagging operations.
