Article considers problems of an assessment of efficiency of company’s activity on the basis of complex indicators of production results and resources. Tools of complex-valued economy – the new scientific direction having the theory of functions of complex variables as the basis – are used to modeling of economic dependences. The properties of exponential production function of complex variables with the real exponent are studied in the work. The function describes the interrelation between complex variable profit and costs of production and a complex labor and capital factor. Elasticity coefficients of complex-valued production function are investigated.

Practical application of the model for forecasting the efficiency of industrial production is considered on the example of " Erdenet Enterprise" (Mongolia). Construction of Kobb-Douglas production function for the analysis of activity of this enterprise was impossible. However the analysis of economic indicators of the enterprise by means of complex-valued production function yielded positive results. Calculation of elasticity coefficients for the function modeling activity of the enterprise, and also their interpretation are given in the article. The conclusion is made about the need of considering such problems as work organization by the company’s management for the purpose of increasing the production efficiency of the enterprise.

The article compares efficiency of sequential and parallel approaches to digital image zooming in software implementation. The method of bilinear interpolation is chosen as a sample. For the study purposes, a test routine was written in С# language. In the tests the operate time of sequential and parallel processing of the same images was compared. To have broader picture, images of various resolution (size) were tested. The article presents plots to describe dynamics of time consumption by accomplished zooming operations in the sequential and parallel approaches versus the original image resolution. The test routine results have confirmed potential speedup of the operation in case of multisequencing. The speedup limitations of multistream implementation of the zooming algorithm have been defined. The article gives suggestions on candidate memory formation for the parallel processing and induces on the best suited operation of the memory, which is the shared memory chart. The presented studies serve as the basis for development of an effective algorithm for large-scale parallelism and parallel-stream pipeline processing in the module of zooming for hardware–software implementation.

Key words: zooming, parallel processing, bilinear interpolation.

This article deals with digital image scaling and optimizing of calculations by means of parallel processing. It is argued that the most efficient structure for this task is that of many-staged processing. Ii proposed to use FPGA as the hardware basis. The main velocity advantage of pipelined approach as compared with one-pass processing is the merit of fast zooming algorithms with a certain factor (in our case, 2) where majority of preliminary image analysis algorithms belong. Combination of targeted interpolation algorithm and pipeline mode allows elimination of consuming multiplication and division processes, using exclusively fast integer addition, diminution and shift operations of modern PLD equal in fast performance to VLSI. With modern PLD-aided scaling, higher response rate as compared to software-only approach is achievable along with the option of system modification.

Key words: image scaling, parallel processing, FPGA.

The rebellious features connected with the implementation of the application of texts and digital images on a surface of bodies with use of the industrial robot are considered. Developed application solves the problem of drawing the image without distortions on the lateral surface of the body using OpenCV library in stages and was written function that calculates and modifies the original image. For development of the program used Irrlicht Engine, creation of a 3D scene and 3D model of the cylinder, and the OpenCV library for image processing. The algorithm of the PrepareImage function is developed. Another application CylPrintModel is developed, demonstrating the painting process of the lateral surface of the cylinder without distortion proportionally on both axes using prestaged flat image using PrepareImage. Both applications are designed to support the model of painting the lateral surface of the cylinder with digital image quality. Keywords: the digital image, preliminary processing of the image, distortion of the image, image simulation of the surface coating

Energy auditing is the primary element for realization of the state policy of the energy effectiveness. The goal of energy auditing is to determine (find out) initial condition (situation) of the energy (power) complex, to take strategic management decisions and to develop complex (composite) programs for energy conservation (energy saving) and energy effectiveness of the enterprises, but the key points are realization of the energy conservation measures and monitoring of energy consumption at the determined level after recommendations’ introduction. Such serious measures are taken by developed countries. Developing of the energy conservation programs is the final stage in Russian practice, it connected with the high costs on program realization and absence of company’s own funds and opportunities to attract borrowed funds. There is no aid from the state assistance in order to take such compulsory high budgetary measures, at the same time there is no determination of the finance source.
