Improving the Methodology for Calculating the Average Turnover of Gondola Cars of an Iron and Steel Plant

Abstract

The average daily mileage of a wagon, its productivity and turnover determine the level of efficiency of rolling stock use. The car turnover is calculated and normalized not only for the fleet as a whole, but also for each type of rolling stock, for a particular region and road, depending on the nature of the transportation work. Accelerating car turnover increases its productivity and increases profit of an operator company. At the same time, its decrease negativ ely affects the capacity of the infrastructure, entails an increase in the cost of shunting and train work, which means that it will increase the cost of transportation. In modern conditions, turnover is determined for each participant in transportation in accordance with his area of responsibility. For an iron and steel plant, the use of an optimal methodology for recording the time spent by a wagon on its tracks allows us to adequately assess this important quality indicator, as well as to monitor its change as a result of introduction of new technologies for transport maintenance of workshops, reconstruction of station layout and optimization of the transportation process. The objective of the study is to improve the methodology for determining car turnover on access roads of a metallurgical enterprise for universal rolling stock in the context of dual operations. The authors use general scientific methods, mathematical methods, comparative analysis. This article presents the main provisions of the methodology, which will allow determining turnover of gondola cars subject to a single or dual operations in the form of a single indicator which is average weighted car turnover.
