Application of the method of the principal components at the analysis of bearing ability of the wheel pair of the car. In this article it is given proof of the method of the principal components to the analysis of calculation of the stress-deformed condition of the wheel pair of the freight car. The statistical result estimation method allows to get mathematical models for researching parameter...

In the freight car dispatching problem empty freight cars have to be assigned to known demands respecting a given time horizon and certain constraints. The goal is to minimize the resulting transportation costs. One of the constraints is that customers can specify the type of cars they want. It is possible, however, that cars of certain types can be substituted by other cars, either in a 1-to-1...

Abstract Rail freight transportation is involved with highly complex logistical processes and requires a lot of resources such as locomotives or wagons. Thus, cost-efficient strategies for routing cars in cargo network are great interest railway companies. When it comes to single wagon load traffic, trains usually formed by collecting individual into batches at shunting yards, order transport t...

Freight transportation is characterized by highly dynamic information processes: customers call in orders over time to move freight; the movement of freight over long distances is subject to random delays; equipment failures require last minute changes; and decisions are not always executed in the field according to plan. The highdimensionality of the decisions involved has made transportation ...

A fair cost allocation scheme is critical for forming and sustaining horizontal cooperation that leads to cost reductions. In order to incentivize suppliers to cooperate in freight consolidation, we design a cost-sharing mechanism to solve a cost allocation problem arising in freight consolidation among small suppliers: that is, suppliers whose total demand fits into one truckload. This cost-sh...
