The dependence of the demographic situation of migration flow showed by the example of the three simulated countries with different social and economic indicators

Pyrov P.V., Butusov O.B., Nikoforova O.P.


The authors developed the mathematical and computer models to simulate migration flows between countries. The main control parameters of the model are the following socio-economic indicators: levels of health care, education and environment, as well as the level of technological development. The model can be offered for monitoring, forecasting and management of migration flows.

System of decision making support based on the fuzzy algorithm for selection of a supplier in the supply chain

Butusov O.B., Dubin M.E., Meshalkin V.P., Nikoforova O.P.


The authors developed the system for support of decision making for the rational selection of the supplier in the supply chain, using the analytic hierarchy process and the algorithm based on the operations of fuzzy sets theories. The functioning of the decision making support system has been verified experimentally on the real accounting and statistics data. The results of numerical experiments confirm the efficiency of the algorithm for making logistics management solutions.

Mathematical model of heat network and development of recommendations for calculation of the efficiency for arbitrary temperature graphics

Sister V.G., Yamchuk A.I., Polivoda F.A.


The authors offer a generalized heat network mathematical model, on which basis it is possible to study the heat network for various methods of regulation, including quantitative and qualitative regulation of heat load. The work allowed to obtain the equation for calculating the efficiency of thermal network in analytical form which gives the opportunity to design organizations optimize the length of transmission of a heat-carrier, to determine the optimum flow of hot water in the pipeline and its diameter.

System of optimal control the cellulases biosynthesis

Zubov D.V., Paramonov E.A., Tolchenov A.A.


The production of enzymes from the waste of food production is of great ecological importance, but there are some difficulties connected with the instability of the raw materials used and the difficulty of operational control of the fermentation process. The paper proposes to use periodically updated mathematical biosynthesis model of the enzyme to determine the best moment of the process cessation.

Water supply system regulation in towns of England in the Tudor period

Bashmakova E.V.


This article considers the methods and techniques of urban water supply regulation in England in the late XV - beginning of the XVII centuries, as one of the most important aspects of municipal infrastructure development. Changes that have occurred in the field of water supply system in the Tudor period, make a new look at the question of the role and place of municipal authorities in the formation of public utilities.
