Optimization of track distribution of industrial railway stations between car designations

Purpose. To improve the method for distributing tracks of industrial railway stations accumulation car groups between separate assignments. The optimization problem is to find such a distribution classification work marshalling yard and freight stations, as well individual destinations, which ensures minimum time expenditures on shunting work. Methodology. studies were carried out using methods theory operation, simulation modeling dynamic programming. Findings. sorting an enterprise, searching work, has been solved. Originality. paper proposes formalizing solving destinations programming problem. Unlike existing methods, where number considered constraint, in proposed method, objective function argument minimizing duration operations, improves quality solutions obtained. Practical value. paper, due rational track arrangement makes it possible reduce making- breaking-up trains transfers and, this, increase carrying capacity cost production enterprises.
