On the method of forming regular container lines on the inland waterways of the European part of the Russian Federation

According to Goldratt's theory of constraints, it is proved that the capacity of the water transportation system for the European part of Russia is determined by the capacity of the locks of the cascade of reservoirs on the Volga River from Yaroslavl to Astrakhan, on the Kama River from Perm to the Kama Estuary. When forming a cargo transportation scheme, a solution of multi-section pushed trains is proposed, ensuring maximum use of the lock chamber space and compliance with the approach schedule to the gateway, accordingly, minimizing fleet downtime while waiting. The solution to the problem is the formation of regular container lines of barge-tow trains, a method is proposed for dividing the waterway into sections connected through the raids of nodal ports and the raid of the reformation of trains. The rational way of servicing non-self-propelled cargo vessels is determined by the choice of the form of tonnage traction for the main transportation routes, the type of tonnage traction maintenance – route or section, in which the expediency of routes and usage patterns are determined by the technology of combined shipments. The increase in productivity and carrying capacity of the fleet is achieved by eliminating the waiting time for the pusher tug to complete loading and unloading operations and the waiting time for the pushers to arrive at each other. Similarly, the formation of container lines is considered as a prerequisite for the connectivity of each port of departure with each port of arrival. Compliance with the schedule requires the use of regulation of the vessel's speed regime. The article discusses the generally accepted option of adjusting the time through additional stops. The travel time with cargo is calculated according to the rational and economical speed of movement, and the lock-in time does not include waiting time, since the arrival of the train takes place at a pre-agreed time.
