On the practical scientific approach to transport service for a metallurgical works

The theoretical, methodological and practical approaches to the scheme of transport service of the metallurgical works are discussed in this paper. Some crucial factors of the delivery of material resources (MR) and pickup of the finished product have been taken into account, in particular, the loss of profits due to blockage of use of the fixed and circulating assets invested into MR during the delivery period, the compensation of environmental and aerial pollution caused by the MR delivery, and also the loss of profits caused by the delays in delivery.

On the improvement of the organizational structure of temporary stores

The decision of systemic engagement with the market of customs is made by the public corporation "Russian Railways" in order to increase its part in the imported and exported freight treatment. The project of development of the temporary stores system (TSS) is initiated and currently realized in connection with this decision. The existing approaches to the TSS control and possibilities of optimization are analyzed in this paper.
