Different variants of technological chain can be organized in logging process. Water or land types of transport can be used for transportation of timber. The use of timber landings where wood can be processed also increases the number of multiple variants of technological process. Performance of operations in various natural and production environment differs in productivity and material costs. Production efficiency depends on the choice of technology of logging operations in dynamic natural and production environment. The given research suggests the variant of the grapho-analytical model for solution of the set task. Detailed graphic models of transportation of wood from logging unit to consumer, loading /unloading and processing operations at the intermediate and lower timber landing are developed. They show possible options of technological chains of logging process. Mathematical dependences are shown on the basis of the problem of finding the maximum flow of minimum cost in the suggested dynamic network. They define the conditions for solution of the set problem.
