Optimization of Maintenance Service Parameters on the Example of Motor Transport Company Located in the North-West Region of the Russian Federation

In the paper, based on the analysis of the consumption of spare parts for internal combustion engines made by the Cummins Company and used by the LLC PITERAVTO motor transport company, the necessity of quite a substantial reorganization of maintenance and logistics services is justified. Such reorganization would certainly improve the economical performance of the service. It is noted that a poorly developed system of technical service and rolling stock utilization, such as logistic service, leads to higher costs of component materials, spare modules and units, and also increases the downtime of equipment due to unproductive reasons. As a method of optimizing the maintenance service parameters for the area covered by transport services, the center-of-mass method is used. The paper formulates the goal function and considers the constraints set to ensure the practical application of this method. Using the method would allow to optimize such parameters of managing technical service and rolling stock utilization in a motor transport company as the optimal number of service centers, their locations, staff and equipment, as well as to define requirements for the organization of warehouse services in terms of the spare parts nomenclature, periodicity of supplies, etc., which, in turn, could reduce the expenditures on spare parts and components and improve technical-and-economical performance of the whole company.
