The current great expansion of automation and robotics affects a multiplicity of various fields. A prominent example is industry, where the different manufacturing processes and technologies embrace a certain level of automation and robotics. Thus, the use of robotics and automation implementation is part of a rapidly rising trend in industry. The presented paper deals with the manufacturing segment in the context of automation. The main subject is data analysis, with our own subsequent model building and final realization of the prediction corresponding to the machinery and electrical machinery sector as a highly relevant automation driver through the use of mathematical modeling. The design of the model is accompanied by optimization of the particular weights. Determination of the most suitable model is preceded by creating and testing a number of models to decide upon the final one. The construction of the mathematical model pursues the aim of making predictions relating to the machinery and electrical machinery sector for the specific national economy as the concluding investigation step. We apply a polynomial approximation as the research method. The software selected for our purposes is Matlab.

“…Taking into account the above in the development process of observation project can significantly influence the technology of field measurements. In articles [2][3][4][5][6][7][8][9][10][11][12][13] consider some methods for deformation observing and as conclusion is taken that the polar method of determining coordinates (spatial polar intersection) is best. There some options for its implementation.…”

The article presents the observation and evaluation method for deformations based on the use of spatial polar intersection, which is implemented by tacheometers. In the classic version, observations are carried out from fixed stations to determine the coordinates of the deformation marks, while the instrument is centered, leveled and oriented. The proposed methodology is based on two technologies for performing work: from fixed points and from free stations. When using fixed points in the first version, the total station is centered, leveled and oriented to a remote target that is the same for all stations. In the second variant, in the absence of a common remote target, measurements are made of the magnetic azimuths of the directions used to orient the instrument. In both cases, it is not necessary to have change points between stations. The option of transit traverse is possible. When observing from free stations without using change point and reference marks, it is proposed to proceed to invariant values for estimating deformations. Such invariants, in particular, are the distances between marks. The results can be used to observe the deformations of various buildings and structures.

The article considers the definition of absolute types of deformations, such as transfer and rotation of a building, using linear spatial intersection. In particular, knowing the distances between strong points and deformation marks, the coordinates of the marks located on the building in the initial and current observation cycles are obtained. Knowing the coordinates of the marks, calculate the displacement vectors of the marks for a certain period of time. The definition of absolute deformations is based on the estimation of the projections of the displacement vectors on the coordinate axes, as well as the direction cosines of the vectors with the coordinate axes. The determination of the direction of displacement is shown for the transference deformation. And how to determine the axis, the distance to this axis and the angle of rotation is shown for rotation deformation. We show for joint deformation of the transfer and rotation how divide it into components and then determine the direction of displacement and the axis of rotation. The results can be used in assessing of absolute deformations buildings of monuments of cultural heritage.
