The necessity of using a systematic approach in constructing a working model of the economy is shown. The need to improve the system level of the economy is discussed. The main reason, «the financial and economic» crisis, which disturbs the balance between the supply of goods and effective demand for them is called the category of «profit». Reference is made to the Institute developed a “model of high performance of the national economy”, which will eliminate all negative phenomena inherent in the modem model of economic activity and GDP increase several times.

The mathematical formulation of solution algorithm for a vector optimization problem on two indices with regard to scientific substantiation of a flexible line of car repair is presented in the paper

Negative aspects of traditional production-and-conveyer lines for wagon repair are shown. Advantages of a new type of wagon-repair flow – asynchronous flexible one – are considered. An aggregative system is suggested as a mathematical model of functioning of the asynchronous flexible flow. Peculiarities of interaction between aggregative subsystems are demonstrated.

A critical analysis of existing methods for repair of freight wagons is presented. The conclusion, that with probability nature of repair activities the “classic” type of a “rigid” production line with regulated step in long-term outlook is inexpedient, has been done. The further development of production-line wagon repair activities is seen in the creation of advanced enterprises equipped with multi-object flexible asynchronous systems with high level of mechanization and automation of technologic processes.

Advantages of stream methods of production are demonstrated. Causes affecting their insufficient use in existing repair of wagons are considered. Further ways of realization of stream idea in wagon repair activities are suggested. Main notions of asynchronous flexible stream of repair of freight wagons are given. Configuration solutions of the flexible stream organization are presented. The calculation procedure of basic parameters of such a stream is given.
