Improving the delivery of wagon shipments by mathematical-statistical methods

The results of the analysis of the delivery time of loaded wagons were determined by mathematical-statistical methods. The delivery time of the wagon shipment was considered in the example of a shipment with a transport distance of 200, 650, 1000 km of the processing process based on the mathematical-statistical method. According to the law of normal distribution, the accuracy of the approximation of the delivery time is determined by V.I. In an examination using the Romanovsky criterion, it was proved that it would be taken into account in the future. The proposed time delivery technology is based on illustrative data on the completion of a specific delivery time provided to the team by determining a coefficient that considers various factors for the next period, i.e., this coefficient determines the daily distance traveled by the wagon for the next period.
