The study of the method errors depending on the choice of numerical approximation of the linguistic variables used is proposed. It is obtained that the necessary condition for the absence of objective (independent from the opinions of experts) reasons for the inconsistency of paired comparison matrices is the closure of the numerical scale relative to the composition of estimates. . In particular, for the classical Analytic Hierarchy Process coming from the works of A. Saati, such a scale is not closed. When the criteria of one level of hierarchy are not the same in terms of priorities relative to the overlying goals (and this situation often happens), even one expert Advisor, in principle, cannot give a consistent matrix of paired ratings. What, in fact, is due to the great attention in the classical considered technology to the methods of estimating inconsistency of the matrix of paired comparisons and its minimization. As the number of experts increases, this effect increases. A closed evaluation scale can be obtained from successive degrees of one any number. For purposes of powers of a number is 1.5, although not ruled out another choice. Для таких шкал объективные причины возникновения несогласованности матицы парных сравнений отсутствуют, а субъективные, связанные с несогласованностью мнений эксперта, могут быть устранены в процессе формирования оценок. The proposed method is explained by a concrete example of the use of the hierarchy analysis method in the assessment of personnel risks in small non-commercial projects.

Currently, issues of development of power efficient hardware blocks for digital signal processing (DSP) devices gain special importance. This is due to the rapid flourishing of wearable electronics, the Internet of things (IoT), network and telecommunication systems. The key component of many DSP devices is a finite impulse response (FIR) filter. It is not surprising that currently a large number of scientific papers are devoted to the development of power efficient FIR filters. The article proposes an original approach to the issue solution. As a methodological basis, modular arithmetic was chosen, already proven as an effective mathematical apparatus for the development of high-speed DSP devices. Another solution was the use of the FIR filter transposed form and methods for constructing the reduced blocks of the multiconstant multipliers. The experimental part demonstrated the efficiency of the block reduction methods of the multiconstant multiplication from the point of view of the filter power consumption. The article also made recommendations for the use of the proposed methods for specific implementations of the FIR filters.

Energy costs for grain drying are about 30% of the total energy consumption for grain produc-tion. Reducing the energy consumption of drying is possible due to the use of a microwave field. In this case, it is necessary to develop a design of a convection drying zone with a microwave field which will provide uniform drying of the grain throughout the volume. For this purpose, it is advis-able to carry out the simulation of the process. The developed computer model of heat and moisture exchange in the grain layer allows to model one under varying parameters of the grain layer and the drying agent. A computer model implements a stepwise calculation method. According to this method, the grain layer is represented as a series of computer models of the elementary layer. The grain layer is divided into three sections. The specific power of the microwave field is set to con-stant throughout each part. In addition, the model takes into account the features of changing in the specific power of the microwave field in the drying zone from the moisture content of the grain and the distance from the magnetron. The air flow in the microwave convection zone can has an im-portant value for the energy intensity of the process. The paper presents the results of modeling grain drying with two variants of air distribution in the microwave convection zone. Graphs of changes in grain moisture in each of the sections of the layer are given. It is shown that when the air moves from the magnetron, the time and the non-uniformity of drying decrease.

Background: The quality of electricity is one of the main problems necessary for the normal functioning of responsible technological processes in which a slight distortion of the supply voltage can lead to a violation of the normal operation of enterprises. There are several solutions to this problem: uninterruptible power systems, fast automatic power reserve technology (FAPR), dynamic voltage distortion compensator (DVDC). The most interesting solution is the application of dynamic voltage distortion. Material and methods: The principles of constructing a dynamic voltage distortion compensator with multilevel voltage inverters are investigated. An imitation model constructed under the following assumptions is proposed: an ideal case of the main circuit system (without higher harmonics) is considered, the nonlinearity of the transformer is not taken into account, short-circuit currents are absent, only constant load power is used. Assumptions are justified by the fact that in practice their error is no more than 3-5%, which is permissible. The results are obtained by modeling the system in the MatLab 2016b package. Results: A fundamentally new structural and functional scheme of a dynamic voltage distortion compensator with a multilevel system is developed. The requirements for the dynamic compensator of voltage distortion, load, LC-filters, current-voltage transformers and a converter are determined. Simulation of the simulation model has shown that the system works and corresponds to the expected results. Conclusions: The proposed voltage compensation system will solve the problem of the normal functioning of technological processes. The simulation results showed that the declared functional of the DVDC provides compensation of the voltage level in a given range of voltage dips. The obtained results can be used to stabilize the power supply: in the power supply systems of medical institutions, electric transport, critical energy facilities of a high category.

Since users can have very different preferences, the personalization of surrounding devices is of paramount importance. Several approaches have been proposed for establishing such personalization in the form of machine learning or more specialized approaches to learning based on scientific knowledge and innovations. Despite great advances in optimization, evolutionary algorithms in this context have been little studied, mainly because they are known as elements that are slow to learn. Anyway, at present there are quite fast optimizers based on evolutionary algorithms. In this article, an analysis is made of the suitability of evolutionary algorithms for "ambient intelligence".

A research software complex was developed to form the behavior of a mobile robot in a nonstationary environment based on the e-puck robot. The complex includes the method of additional training of the robot, cluster analysis and the modified algorithm Q-learning, which ensures the robot's movement to the target. The recognition algorithm is based on the concept of ""similarity"" between images from the robot's camera and the standard marks of object clusters formed in the learning process. Standards are formed gradually from ""similar"" labels. If the label is ""similar"" to the existing standard, then the object has already met before and the corresponding action of the robot is also defined. Otherwise, a new cluster is created, so there is additional training. The number of objects is almost unlimited. To ensure the movement of the robot to the target, the Q-learning algorithm is used with reinforcement. It is based on the use of the matrix of the expected reward Q. Knowing the current state of the environment, the robot chooses an action that is expected to bring the maximum reward. The reward is given if the target label is in a certain area of the frame of the video camera and has a certain size. Initially, the matrix Q is given randomly. In addition, at each step the matrix values change in such a way that the matrix gives optimal control in any situation. In the case of the robot e-puck, the possible actions are rectilinear motion or turn (left / right). To overcome the problem with several targets, the algorithm uses several reward matrices Q. When a new goal occurs, the algorithm creates a new reward matrix. In this modification, all matrices Q are subjected, regardless of the target the robot is looking for. The final decision on the action of the robot takes on the basis of a matrix corresponding to the current goal. Despite the difficulties and problems that have arisen, it has been possible to implement a complex that can be relatively easily transferred to another physical platform and can be used to create more sophisticated intelligent systems.

The work is devoted to modeling the dependence of the temperature of the extrusion process in the melting zone on the composition of the feedstock and the rotational speed of the screw shaft. The quality of the finished product can not be determined in real time, but it depends on the values ​​of the technological parameters of the production process. Therefore, the quality of products can be controlled through the control of technological parameters. Therefore, the problem of determining the temperature dependence is an important problem. The model is obtained on the basis of experimental data from a number of alternative models. As parameters, the rotational speed of the screw shaft was used. As a criterion for the quality of the model, the sum of the theoretical model errors from the experimental data is used. As the speed of the screw shaft increases, the temperature of the extrusion process increases with a gradually decreasing rate. The resulting model of the extrusion process can be used in automatic extrusion control systems to control the quality of finished products.
