Summary: For the automated planning of timber rafting based on improved flat rafts software has been developed to take into account the design features of flat rafts, raft section lines formed from these flat rafts, and rafts based on them. The software is used to calculate the transport and operational performance of improved flat rafts, as well as lines and rafts based on them, depending on the values of the factors influencing these indicators of improved transport units. The presented software also makes it possible to study the dependence of transport and operational parameters of improved flat rafts on the main factors affecting the efficiency of rafting operations. Computer planning of timber rafting in rafts was performed on the basis of improved flat rafts by calculating their transport and operational indicators for the spring, summer and autumn periods of the year, taking into account the accepted conditions for the performance of rafting operations. It has been established that in the spring period raft section lines and rafts should be formed from flat rafts, the design of which corresponds to RF Patent no. 2777676. For the summer period, it is rational to use a raft section line formed from flat rafts made according to RF patent no. 2777676, and rafts should be formed from raft section lines comprising flat rafts which are manufactured according to RF patent no. 210485. At the same time, in the autumn period, it is advisable to use raft section lines and rafts formed from flat rafts made according to RF Patent no. 2777676. Since the main purpose of timber raft is to transport the maximum volume of wood on the initial timber raft, in the spring, summer and autumn periods of the year it is recommended to use flat raft units made under RF Patent no. 2777676, as well as raft section lines and rafts manufactured in accordance with RF Patent no. 2811178.
