Abstract In this article the present approach to inter-preting failure density function was considered. There was determined the value of the gamma-percentile life in case of independent failures, which are described by normal distribution. The conclusion of the article is that the best way to get the value of failure density function when gamma-percentile life is constant is using the Pearson distribution. Accuracy of the results of Pearson distribution is high, and calculations are rather simple.
Keywords resources, failure, function, prognostication, value, repair of cars.

Abstract The article examines algorithmic and techno-logical problems of server-smartphone distributed system to collect and process information about maintenance of motor roads.
Keywords distibuted systems, information processing, smartphone.
Abstract We describe a modification of the algorithm of ant colonies with parallel, enabling a search for the optimal trajectory of movement of the cargo hoisting machine of arbitrary shape in three-dimensional space with arbitrary constraints, as defined in discrete form, taking into account the angular orientation of cargo.
Keywords swarm algorithm, ant colony algorithm, parallelization, planning the optimal trajectory
Abstract In article questions to qualitative and timely clearing of an asphalt covering from the snow helping optimum to pick up necessary quantity of units of the snow-removing technics are considered. Depending on conditions of works, the optimum weight of a snowplow is defined. Analyses of existing methods of definition of quantity of cars for cleaning of city territories are resulted. The technique of definition of opti-mum quantity of units of snow-removing technics is presented.
Abstract The article gives definitions of supply chain, adaptation and adaptive-operational activities. The most promising ways to improve the operation of distribution system during the stage of transport-logistics hubs are considered. A simulation model of adaptive-operational activities is generated.
Keywords transport-logistics hub, supply chain, model of adaptive-operational activities, freight transportation, logistics.
Abstract The given work is devoted problems which are shown today by a modern civilization and are realized to some extent in a context of existence of a modern megacity. Work is as a matter of fact a certain short filosofsko-cultural exposition of human existence in a modern megacity where safety of citizens, both in a life, and in a traffic context directly depends on cultural level of each separate person, from its skill to communicate, responsiveness, possibilities to come to the aid and to love on kindness.
Abstract Car accidents are the independent object of social and economic research, which requires a statistical estimation. However, current statistical reporting of car accidents in our country has departmental character. The content of the statistical reporting shows the blind spots and gaps of the methodological character, which keep from collecting reliable information and receiving accurate estimates of real situation with road accidents and their consequences.
Keywords car accidents accounting, statistical analysis of car accidents, indicators of car accidents, amount of car accidents, death rate in car accidents.
