Abstract Article is devoted a problem of minimisation of costs of the road-building enterprise at the expense of introduction and correct operation designed ASUP. Comparison existing ASUP with ASUP the road-building enterprise is spent. Economic indicators for 2007 and 2008 on an example of state unitary enterprise "Orenbur-gRemDorstroy", and also calculations of eco-nomic indicators from the decision of problems of logistics are presented.
Keywords ASUP, the road-building enterprise, a transport problem, a storekeeping problem.
Abstract The paper deals with the problems relating to the limiting task set while developing integration infrastructure. The term technological information is being introduced. Examination of integration architecture is guided in terms of technological information transmission system between automated management applications.
Keywords integration, technological information transmission system, algorithmization, management.
Abstract Summary Descriptions of structures of distributed industrial automated control system with included systems of vital functions are presented in article. The methods and models descriptions of the control of system functio-nality are described.
Abstract The present article considers the mechanism of processing of queues FIFO in the distributed systems is considered, taking into account their features and the proof of efficiency of the given mechanism in comparison with known methods of processing is resulted.
Keywords Distributed systems, queue FIFO, service desk, demand processing, queue with priority.
Abstract In work results of working out algorithmic and the software for automatic detection of the person and its characteristic large elements (eyes, a mouth, eyebrows, a nose), trackings these objects and their subsequent display in real time on the personal computer of type IBM PC are presented .As an input equipment the web-chamber is used. Results of allocation of borders of eyebrows, a nose and a mouth are approximated by splines or several characteristic points. All information allocated thus is represented in the form of vector graphic elements for the transfer on networks or the further visualization by means of a machine drawing in real time.

Abstract We consider the fluctuation of band multilayer structures of roads. General statement of roads forced oscillations problem is suggested, allowing equations are formed the problem of its own heterogeneous structures elastic oscillations is solved.
Keywords vibrations, band structure, multi-layered, heterogeneous structures of the roads.
Abstract The active development of the underground areas of modern metropolises sets the task of ensuring radiation safety for construction and maintenance operations within the underground transportation objects. Reliable methods of forecasting of the concentration of radon in the underground areas will enable to decrease the cost of ecological radiation investigation and to increase its efficiency. Implementation of such methods is slowing down because of the lack of data regarding diffusion coefficients of the materials used.
Keywords radioactive ecologic safety, Radon, equilibrium equivalent concentration of Radon, diffusion coefficient of Radon.
