Mathematical model for determining the total cost of forest land resources taking into account the level of development of the forest transport network

In modern economic conditions the principles of sustainable development of forest fund territories impose the industry to ensure multi-purpose, rational, continuous, inexhaustible forest management. It is obvious that one of the key factors in achieving sustainable forest management is the efficiency of managing the value of forest benefits as objects of national wealth. This circumstance makes it necessary to determine the value of a forest resources total cost indicator. The transport network on the territory of the forest fund (TNFF) is of decisive importance as it provides both forest use and converts the value of forest resources into a part of the gross proceeds from their sale. Consequently, the transport accessibility of forest lands is the main factor in assessment of the resource potential of the forest fund territories. Thus, one of the key tasks is to develop models to determine the value of the total value of forest benefits basing on an integrated approach in the context of multipurpose forest management and taking into account the level of the forest transport network development. This article analyzes the main methodological approaches to the general economic assessment of forest resources. The analysis revealed that the existing methods for assessing the total value of forest benefits are mainly focused on the use of mature and overmature forests. Other types of forest use and the so-called "insignificant benefits of forests" are either not taken into account, as well as the level of development of the transport network, or the methods of their accounting are not sufficiently developed. Therefore the resource potential of forest areas might be underestimated, which in turn may lead to the loss of forest areas that are valuable both economically and ecologically. In this regard, the development of a complex model for calculating the total economic value of forest benefits in a dynamic setting, which takes into account the level of development of the transport network on the territory of the forest fund and is based on the ecological and economic criterion, is becoming an urgent scientific direction. The methodological apparatus presented in the article is based on economic and mathematical modeling in the context of the combinatorial approach taking into account the dynamics of input parameters. The model is presented with a detailed description of all dependencies included; the advantages of its use are noted.
