Abstract. 

The formation of raw material supply chains is closely related to production problems at a timber processing enterprise. This article examines a forestry enterprise without its own sources of raw materials - allotments, which sets itself the goal every day of solving the problem of forming supply chains for raw materials from the exchange and the optimal loading of production workshops. A commodity exchange is considered as a source of raw materials, where lots appear every day in different regions in a random order. The paper considers a mathematical model, which represents a mechanism for making decisions on each individual day over the entire planning horizon and is distinguished by the fact that it allows taking into account cutting technology, lot travel time under conditions of uncertainty. An additional difference is that the search for a solution is based on the calculated optimal trajectories of raw material inventories in the warehouse for similar previous planning periods. The model was tested on data from the Russian Commodity and Raw Materials Exchange and one of the Primorsky Territory enterprises. Analysis of the solutions obtained showed that even with a rather complex scenario for the development of events, the model shows qualitatively high results.
