A PLANNING MODEL FOR OPTIMUM USE OF TIMBER TRANSPORT ON THE ROAD NETWORK
The main phases of timber production, transport and process streams, the number and nature of these processes, place, order and means of implementation, and the types used in each case, raw materials and derived products are a difficult fundamental problem whose solution is impossible without the improvement of methods, models and algorithms for solving problems of governing in multi-level transport and production systems in forest sector. The relevance of the research problem in transport development and increase of economic efficiency of available resources use is really important because the existing transport systems are not exploited to the full (a large number of inefficient transport for timber, not enough reasonable distribution of traffic volumes by mode of transport, rolling stock, etc.) that results into increase in transport costs. The research was carried in the field of development of methodological approaches to the construction of complexes of interrelated models of analysis of the transport development and its functioning. If transport is an element of the national economy then the analysis of the links in this sector with other sectors of material production is based on the study of the proportions between the volumes and structure of forest products and the products of all other industries. The problem of multi-level management of transportation and production systems is very vital but poorly covered in the literature on the forest complex specialties. The main phases of timber production, their production sites and technological streams include sequential or concurrent operations. The number and nature of these processes, place, order and means of implementation, and the types used in each case are determined by the timber production process. The analysis in this part is suggested to do on the basis of mathematical models of inter - sectoral balances, in particular, for the analysis of quantitative relationships of the production process, assess the impact of various factors on the dynamics of economic development, to analyze the prospects of their development. Methods and models of work distribution between modes of transport are based on the analysis of network models. These models were tested on conditional data, so they need further studies on specific practical information.
