Abstract Is developed model of management by сompetitiveness of the motor transportation enterprise, based on comparative consecutive estimations of сompetitiveness of the services, competitive potential and competitiveness of the enterprises. The example of application of three-stage model in practice is resulted.
Keywords competitiveness, the model of management, motor transportation enterprise.
Abstract In article the basic postulates of the developed theory of equilibrium dynamic systems as formal analogue of real market systems are considered. The offered theory has allowed to develop set of mechanisms of decision-making which with a sufficient degree of reliability predict behavior of market systems. It formed a basis for lines of the strategy providing a positive prize. The mentioned mechanisms of decision-making and the strategy developed on their basis have been put in a basis of the program complex.
Keywords auto transport, bringing in of capital, promissory financing, debt funds.
Abstract In article development and introduction problems of the mechanism of increase of efficiency of functioning of a control system of the auto-transport enterprise working in area of the international automobile transportations are investigated. The basic directions and the tasks of the program on introduction and functioning of the given mechanism are considered. The technique of an estimation of influence of a control system on results of industrial and economic activity of the enterprise working in area of the international automobile transportations is presented.
Keywords international transportations, competitiveness, management system, mechanism model.

Abstract The article considers the issues of using simulation models of inventory management processes at the maintenance enterprises. The above models serve for improving the efficiency of planning and, hence, minimizing the costs of storage. In his article, the author also describes the possibility of converting the inventory management process into the regenerating process. This allows obtaining statistically substantiated results.
Abstract The article analyses methods of technical and economical substantiation of the reliability of production systems. It is shown that the operability restoration, as well as any other measures aimed at increasing reliability of equipment, require significant one-time investments, as well as the investments on a regular basis. These investments, in turn, decrease the expected economic performance of the system. This inter-dependency is analyzed in the article, and the main calculation models are presented.
Keywords reliability of the production systems, coefficient of efficiency, coefficient of readiness.
