The article deals with the formation and optimization of the technological transport system of a timber enterprise. Problems were identified in the formation of cargo flows of forest material. These include poor development of methods for designing transport systems in the timber industry and disunited transport links in the operation of the enterprise. Computer simulation allows the operator to change the parameters of the designed system to optimize it. A multi-level algorithm for designing the transport system of the LPC is also proposed, including: determining the initial parameters for the design; calculating the number of vehicles; developing a simulation model of the production process in the LPC; calculating the technical characteristics of the transport system; developing an algorithm for managing the transport system; selection of the transport system option. An analytical calculation of the use of different quantities of trucks when loading vehicles is made in order to find an economically profitable number of them. As a result, calculations were made to compare the performance of the transport system with different quantities of loading equipment. When we received them, we saw that changing the number of loaders affects the capacity of the entire transport system.
