Abstract
An analysis of existing methods for optimizing the transportation work of locomotives in operation is presented, based on a refined formulation and criteria for the problem of optimal control of train movement by locomotives of different types of traction. The advantage of the dynamic step-by-step programming method proposed by the author, based on the principle of parametric optimization, is substantiated, which makes it possible to calculate optimal train driving modes in areas of locomotive circulation and locomotive crew work with savings in natural diesel fuel consumption of up to eight to ten percent per trip. The analytical dependence of the stepwise optimization of the process, which determines the sequence of solving the optimization problem, is recommended to be used in the development of optimized train driving modes maps on sections of the Uzbek railways of varying difficulty.
