Оценка вариантов методики определения баланса парка полувагонов с помощью регрессионно-корреляционного анализа
Annotation. The article discusses the results of calculating the balance of the gondola car fleet using four alternative methods and shows how the dynamics of the rates of rolling stock operators are related to the surplus level. A method for assessing the correctness of various methods for calculating the surplus using regression-correlation analysis based on the relationship between the dynamics of the surplus and the dynamics of the gondola car rental rate is proposed.
Key words: surplus of wagons (open wagons), rates of rolling stock operators, balance of wagon fleet
