Effective interaction of society, government and business in a market economy is one of the main factors affecting the sustainable development of all sectors of the economy, including the forest industry. The aim of this work is to develop a concept and tools for assessing the impact of management decisions of individual economic entities of the forest industry on the sustainable development of the region as a whole. All economic management decisions are essentially divided into three groups: operational and production decisions, decisions on wages and decisions on profit distribution. The authors propose a tool to assess the impact of management decisions of forest industry enterprises on the sustainable development of the region using an integral indicator calculated as a result of summation of indicators characterizing the impact of management decisions of enterprises operating in the municipalities of the region.

Mathematical modeling in optimization problems of management of urban passenger transport in large cities is considered. The simulation of route of transportation network of large cities is determined by a relatively large number of their specific and individual properties which, in the process of their functioning, become more complex and interdependent ones. Algorithm of rational route network taking into account annular and circular routes in the schemes of organization of urban passenger transport is proposed.
