The problem of reducing the costs associated with the performance of work at the construction site, is relevant in view of the ever increasing cost of special equipment and materials used in con-ment, the tightening competition in the construction market. One of the ways to reduce these losses is the search of an optimal variants of the organization of the construction process, in particular for road construction equipment and above all Conveyor (TCP). That this problem is devoted to this work. In the formalized problem of minimizing the losses and costs associated with the delivery with the implementation of various support accompanying PTS use processes. Accounted for a large set of facts which could have a negative impact on the process uses the TCP-tion. These expressions include seven support functions, which in turn depends on a number of constants and simple functions. We studied two of the seven auxiliary functions on demand-built bathrooms in models obtained analytical expressions for calculating the values ​​of these functions.

The article describes the solution of the problem of mobile robot ultrasonic positioning in a confined space. The solution of this task is overdue, if necessary, calculate the coordinates of a moving object in an enclosed area of ​​a small size. Most available technology in this case is ultrasonic technology, since it provides sufficient accuracy and more simple to implement. Methods for solving the problem is using a triangulation system, consisting of an object with an ultrasonic emitter and four sensors located at the corners of the permissible area. The mathematical model of the system is a system of nonlinear equations, numerical method can be applied to solve a. The authors compare two numerical methods for solving the ultrasonic positioning tasks: the simplest gradient method and the Levenberg-Marquardt method. The final choice was made in favor of the Levenberg-Marquardt.

In article the factors defining efficiency of roadheader technology application of transport tunnels construction are considered. As one of the factors containing growth of carrying out speed of tunnels is the loading part of the combine, in article the analysis of the factors influencing efficiency is made. Stochastic process of interaction with the destroyed mountain weight is considered. The analysis of the developed approaches to determination of executive body loadings productivity with loading paws with a destroyed mountain weightstack is made. Influence of a form of the immersed material particles and geometrical ratios of loading body and average fineness of material particles is analysed. It is revealed that extent of influence of a particles form doesn't exceed the statistical errors arising at research of loading process of lump mountain weight, and geometrical ratios have significant effect on loadings and productivity. When determining loadings it is offered to apply model taking into account linear proportions coefficient, and it is necessary to apply the model considering influence of active volume on formation of system output characteristics to calculation of loading part productivity. Taking into account influence of the described factors, the calculated value of productivity and loadings increases in comparison with the generalized models that confirms expediency of use of the described dependences.

In this article we consider technique of determination of degree of homogeneity of heterogeneous mixtures by using tool contactless method. This method uses optoleptical information of mixture surface. This method can be used in automatic control systems. An optoleptical information may be obtained using standard devices of photosensitive scanning. The value of entropy of otptoleptical information is used to estimate the degree of mixture homogenization. Operations of component mixing are widely used in technological processes. The degree of homogenization of mixture is the one of quality indicators of mixing process. The degree of homogenization is usually determined by laboratory method, which requires additional time for analysis. The degree of homogenization can also be determined by using the senses. In this case, the results of determination depends on the experience of the expert. In this article we looked at an example for the paint industry. The method can be applied to a wide range of heterogeneous composition.

The technique of the multidimensional analysis of socio-political attitudes is shown on a concrete example. The results of questioning which was carried out in the spring of 2014 among the Rostov region population participating in the work of election commissions of the lower level are the basis for work. In total 144 persons were surveyed. On gender and age distribution, and also on socio-economic indexes our sample was typical for the above mentioned population. About 29 characteristics were used as input parameters in model. They were levels of affective and cognitive perception of the local and central authorities, cognitive estimates by respondents of the relation to various parties of socio-political life, the characteristic of a social portrait of respondents. The affective components were determined by technology of semantic differential, with the subsequent calculation within nonlinear approach. All cognitive components were computed by results of direct poll. Entrance sizes were unwrapped a multidimensional cube on a platform of a package of the multidimensional analysis by IBM Cognos. The functions of respondent’s distribution were computed both for separate components, and for various sections of a cube at the exit of model. The analysis for social and economic, national, confessional, territorial, gender profiles is carried out. It was discovered, in particular, the essential peculiarities in the territorial plan for the main leading factors of a conflictogenity (an affective component of political attitudes). Hierarchy of factors of social tension was created It is shown that the presented technique allows to conduct comprehensive investigation of a socio-political condition of any audience.
