Abstract

We consider the problem of empty tank cars relocation in a railway petroleum transportation. Biggest petroleum carrier in Kazakhstan railway network provides transportation service to the customers. The majority of its expenses consist of an empty run of the cars, as they move to the load stations. Given the demand for empty tank cars, the company seeks to reduce total costs to satisfy all the demand within a planning period. We provide a mathematical model for this problem in terms of integer programming and perform an experimental study with LP solver. Numerical calculations show that new model allows to significantly reduce empty run of the tank cars on the railway petroleum logistics market lowering the total expenses of the company by more than 10% level.
