the formulated problem is a special case of the transportation problem with xed surcharges in which the value of the objective function affect only the time spent on the delivery of resources by the affected routes and do not affect the volumes of transported resources. A solution based on the linearization of the objective function is appropriate in cases of time constraints on finding a solution. Second, because of its relative simplicity, this solution can be used as a duplicate procedure (to determine the lower limit) to more complex, such as, combinatorial, algorithms for finding exact solution of the problem. Modification of the method of Balinsky is the sequential reduction of dimensionality of the original problem by eliminating rows or columns of the matrix of transportation in which the true costs match the costs of these tasks
Keywords: transportation problem, the minimum total time, linearization of the objective function, the method of Balinsky
The model of a numerical estimation of information contents of the Internet sites, based on the thematic analysis of texts is considered.

In the article elements of the distributed systems using the principle of scanning for analog digital conversion and a data interchange are considered. The main attention is paid to the unrolling analog digital conversion of signals with further restoration of analog data with the given accuracy. Distinctive feature of the unrolling conversion is that value of counting of a signal contains information on time from the beginning of conversion. The formulas connecting value of counting of an analog signal over time of counting taking are given in article. This feature is used further for upgrade of formulas of Lagrange. In operation restoration of analog signals with use of formulas of Lagrange after their sampling on time using the unrolling analog digital conversion is considered. It is shown that use of the upgraded Lagrange's formulas doesn't lead to increase in computing expenses, but requires for restoration only value of counting.

Now risks associated with the violation of information security properties become especially relevant, including for medical institutions. This article describes the technique of assessment of information risks, including the algorithm of assessment of the acceptable risk, fuzzy cognitive model and the algorithm of expert assessment of the current risks. The proposed model and algorithm of assessment of current risks allows defining of multiple points that characterize the current level of information risks on a coordinate plane "damage - probability". The main difference between the described method and already existent ones – is determination of asset significance for company that allows making reasonable management decisions in the end. The offered technique has been applied in the state budgetary healthcare institution of Astrakhan region "Medical prevention center": curve of acceptable risk is constructed; the current (relevant) information risks are estimated. Then results of assessment were used for making management decisions on lowering the risks to acceptable values.

The use of water resources to economic activity that is determined a necessity in human existence, all living beings and in almost all technological processes of industrial and agricultural production, fuel and energy complex and other industries, and other activities. At the modern stage of society development at the global level of the system ""Nature–Society–Man"" and the local level of basin geosystems, within which are formed the water resources, there is a strong tendency of the limited water resources within the bounding conditions for further development. Use of water within the local basin geosystems of the southern and Northern Caucasus the river Kuban, Terek and the Upper don, where more than 23 million people. (16.3 per cent of the total population of the Russian Federation)provided by the existing and newly built water system (WS) that in-basin and inter-basin regulation, redistribution of runoff (surface, underground), the selection of a water source and transportation of the estimated costs of water to a particular water user. The aim of the study is to develop a methodology basics of technical theory title of ""environment – Object of activity – Population"" existing in the composition of the WS, in which the main component is man-made hydraulic structures (HS), amending the natural processes of interaction between biotic and abiotic components, requiring a system of quantitative and qualitative assessment.

The article presents a summary of the global positioning systems and their application in the transport sector. The authors offer new opportunities for their effective integration into the traffic control system. In particular, information about the coordinates and speed of vehicles, transmitted to the traffic control system server can be used for adaptive control of traffic lights to control the traffic on dedicated lanes to detect speeding and parking in the wrong place, and many other violations of the traffic Rules. It is also possible extension of the information features car navigator. It is possible to add a "button" for sending location coordinates traffic accident or emergency road section. The main problem, which does not allow is to introduce authors' proposal lies in the fact that the proposed applications of navigation systems suggest a navigator in all or most vehicles. Moreover, these navigators must have access to the Internet. Now these navigators are on the market , but not all drivers have them. Not always navigators work in car. The authors suggest law requires drivers to use navigation systems both in motion and during stops for information on the location of the vehicle and its mode of motion.
