The paper presents a solution for the problem of choosing a method for analytical determining of weight factors for a genetic algorithm additive fitness function. This algorithm is the basis for an evolu-tionary process, which forms a stable and effective query population in a search engine to obtain high-ly relevant results. The paper gives a formal description of an algorithm fitness function, which is a weighted sum of three heterogeneous criteria. The selected methods for analytical determining of weight factors are described in detail. It is noted that expert assessment methods are impossible to use. The authors present a research methodology us-ing the experimental results from earlier in the discussed project “Data Warehouse Support on the Base Intellectual Web Crawler and Evolutionary Model for Target Information Selection”. There is a de-scription of an initial dataset with data ranges for calculating weights. The calculation order is illustrat-ed by examples. The research results in graphical form demonstrate the fitness function behavior dur-ing the genetic algorithm operation using various weighting options. The analysis of the results implies that it is more preferable to calculate fitness function weight fac-tors for this query population then using the results of all population queries. The conclusion is based on the presence of successive improvements in query populations which reflect the correct operation of genetic algorithms, as well as on the obvious detection of local and global maxima in the fitness function during experiments. When using other methods of calculating weighting factors there is no such thing. Thus, a method for determining weight factors for an additive optimality criterion can improve ge-netic algorithm quality to generate effective search queries. In particular, the probability of rapid detection of fitness function local extremes is increased and this local extreme can become the optimal solution the function domain.

This paper appoints the problem actuality of the holding capacity assessment with dangerous freight. The holding capacity transcendence of such hoarder is connected with the large environmental or fi-nancial loss; accordingly, it is a remote contingency. Legally the drive loading is a service operation of the received application. The machinery of the theory congestion system is for modeling of the received application process. The authors showed that it is necessary to take into account the stream no uniformity of orders in service operation modeling. The input and output stream orders are vary wildly in the extent of incoming and out coming freight from it. In the input stream, the orders come by batches, but the output stream has unicast orders. The authors offer to use the analytico-statistical method of the extreme values and the behavioral model of the sequence in the buffer with the limited capacity for solving the original problem. The analysis of the order losing process in the overcrowded buffer of the terminal capacity by the station-ary system of mass service is reduced to the analysis of the sequence build-up and build-down on the refresh interval. The authors got the expression for the low value calculation of the discard probability in the termi-nal capacity buffer in the form of the analytico-statistical value. The authors offered the acquisition and computing technique of the sampled data. Performing sequential steps it makes possible to estimate the required capacity of the final buffer according to the waste tolerance probability.

Chemical reaction is a complex system by a number of factors determine its effectiveness. Assessing the effectiveness of XP in various conditions is an important task. It allows to search for effective con-ditions and to predict the possibility of the reaction under certain conditions. In this paper, there are neural networks to assess the condition effectiveness of the chemical reac-tion course. The author analyzed in detail the conditions that the most significantly affect the chemical reaction course. The author proposed the methods for encoding information about the reaction condi-tions. The author proposed to divide the reaction conditions into two groups – data that can be encoded in binary form and data that must be considered in numerical form. As a prediction tool, the author used the neural networks with perceptron architecture, requiring training with a teacher. As data for teaching neural networks, we can use as experimental data on the сhemical reaction course, as well as the results of the computer simulation reactions. The paper considers two approaches for predicting the chemical reaction effectiveness. The first approach involves the neural network use for the direct prediction of product yields, considering the product yields of chemical reactions as a function of the input set parameters. Another approach to the building a neural network model of сhemical reaction is to build a classification of the conditions for conducting chemical reactions, dividing the input parameters into pre-formed groups based on expert knowledge. The authors tasted this procedure on the industrially important olefin carbonylation reaction, the industry widely use it. For modeling, the author developed the software that allows importing data on сhemical reaction, to carry out training and forecast.

The article discusses the development of algorithmic and software for an intellectual control system for the development of the synthesis of active pharmaceutical ingredients. Based on the analysis of the scheme of the quality control system, the efficiency and safety of medical products, the authors showed that the only non-certified stage in the life cycle of the development and production of medi-cines is the pharmaceutical development stage, which includes the APIs synthesis and the GLF compo-sition development. The authors showed the advantage of the continuous synthesis scheme for the production of active pharmaceutical ingredients over the periodic synthesis scheme. The authors gave a systematic ap-proach to the proposed development based on the implementation of the QbD principle. They devel-oped a scheme for the formation of a global criterion. The authors formulated a range of conditions in which the research is to be performed, while with respect to each condition, the quality of functioning is evaluated by an independent criterion. There are the information models for the control system for the continuous synthesis of diphenhydramine APIs in the IDEF0 notation. The authors proposed an approach to the development of information and software and algorithmic support for the continuous synthesis of drugs. The authors developed the mathematical models based on regression analysis to control the process of continuous synthesis using an intelligent control sys-tem. There is the algorithmic and software based on the freely available Scilab software package for managing the process of developing API synthesis using multi-regression regression models and the Hook-Jeeves optimization algorithm. There is a graphical interpretation of some of the process study results of obtaining the API of di-phenhydramine (diphenhydramine) in an experimental continuous synthesis plant. The authors ob-tained a set of graphic solutions that allows to optimize a number of the synthesis process quantitative indicators of the active pharmaceutical ingredients.

The paper describes the software, which the authors developed. It is for solving the problem of finding the kinetic parameters of chemical reactions. In the conditions of modern industrial production, meth-ods of mathematical modeling of chemical-technological processes are widely used, which allow solv-ing the problems of forecasting and optimizing production at the stage of a computational experiment. To solve these problems, we need the mathematical description of the chemical process, which relies on the construction and observation of the kinetic model of the chemical reaction. The relevance of software development for solving the problem of searching for kinetic parameters of chemical reactions is due to large computational and time costs. The software developed by the au-thors uses the differential evolution method and allows calculating the values of preexponential factors and activation energies of the user-entered reaction from the experimental values of the concentrations of substances. Based on the found kinetic parameters, the authors construct a kinetic reaction model and solve the direct kinetic problem. The calculation results are in numerical and graphical form. For appraisal the proximity of the obtained solution of the direct problem with the experimental results, there are the experimental and numerical values of the concentrations of substances, as well as the val-ues of the relative errors of the concentrations on one graph. Software package approbation of the kinetic parameters calculation was the case of the phthalic an-hydride reaction. In view of the results, there were implications about the satisfactory agreement of the experimental data with the concentrations calculated because of the calculated kinetic parameters. We can use the software tool during the computational experiments in scientific and production la-boratories at the design and modernization stages of chemical processes.

Information technologies are in all spheres of society. They are effectively takes root in the work of fo-rensic experts and criminologists. The use of specialized software can significantly improve the effi-ciency of solving practical problems, and the scientific validity of the conclusions obtained because of examinations. This article contains the algorithm description and the software complex FFRACE, intended to the individual race diagnostic on externally – the head identifying characteristics. The proposed diagnostic algorithm consists of three stages: fixing the basic values externally – identifying features of the indi-vidual head and their numerical score; the probability calculation of belonging to a particular race based on iterative Bayesian Procedure in the modification of A.A. Genkin; establishing racial identity of the individual, taking into account the critical rules. Using the algorithm, the authors developed the unique program complex. This program complex consists of three modules: module for entering basic information; module fixing externally – head identifying signs; module for the race diagnostic. The result of the race diagnostic in the program complex is an expert opinion, which contains a ta-ble of the individual personal information; development variants of each fixed feature; the occurrence probability of this option at the caucasian and mongoloid; the calculated probability of the investigated individual race at each step; final conclusion about the race. If the individual’s race is indescribable, the expert, analyzing the data in the table, can determine the predominance of mongoloid or caucasoid appearance. The software package is for use in laboratory studies, and the location of emergency inci-dents.

There is a developed software to assess the status and the region management efficiency. Management efficiency is a topical problem of modern global management. The software package uses the tool "polar indexes" for work. It offers 3 basic calculations: the current state as-sessment of the region as a whole and separately for sub-systems (economic, social, ecological); assessment of re-gion management efficiency, when there are only those indicators whose values can be changed by management decisions; modeling the state change of the region with minimal financial costs. In contrast to the existing software systems, this complex uses the polar indices tool, which allows to take into account not only the "positive" indicators, i.e. directly proportional to the overall index, but also the "negative" ones, which affect the index inversely. The authors repeatedly used this tool in solving the problems of assessing the dynamics, building a rating, evaluating the effectiveness. The testing results by Fisher's axioms confirm the proper use of polar indexes. The software package is an application Microsoft Excel, which has the most user-friendly interface and has the ability to save the obtained and structured results in accdb-file. The app only uses official statistical data on the official website of the Federal service of state statistics, and, in spite of there is a standard set of the estimated parameters, the user can change it manually, putting the focus system and the cost of one unit of the indicator. The simulation results, which are in satisfactory agreement with the experimental data, confirm the perfor-mance of the software complex.

To complete problems of the Earth remote sensing (ERS), apply panchromatic and multispectral imaging systems for observing visible and near-infrared optical ranges. They have more than half of resolving problems. As hard-ware components go forward and rocket and space equipment improves, an increasing role is to the study of fac-tors determining the quality of the information (images) received. These factors include both technical characteris-tics of optoelectronic devices and image information parameters. There are the main directions of creating a software suite for assessing the factors affecting the quality of re-mote sensing information based on the characteristic analysis of ERS spacecraft optoelectronic devices. These in-clude signal-to-noise ratio (s/n) and the spectral channels informativeness of the spacecraft onboard equipment. The article presents the software suite for assessing the factors that determine the quality of the Earth remote sensing information. The software suite is in the cross-platform framework Qt to develop the software in the C ++ programming language. The software suite implementation contains the appropriate modules, in accordance with the program logic. The calculating module of the s/n ratio of the spacecraft optic-electronic equipment taking into account the param-eters of the optical system and the noise of the electronic path of the spacecraft optic-electronic system determines the s/n ratios in every spectral channel and in the whole equipment. The second software module allows you to calculate the optimal set of spectral channels for display using the Optimum Index Factor (OIF). For users’ convenience, the program has a graphical interface and supports conducting research with the mem-orization in a file.

Metal forming is widely used in the manufacture of products for various purposes. There are crimping operations with the help of a technological tool of crimping matrices to reduce the transverse dimen-sions of the end part of hollow thin-walled cylindrical parts. Receive a crimped cap of cylindrical cans, aerosol containers packaging, different adapter pipes and other products. The high costs of experi-mental work and production of pilot batches lead to the relevance to create automatic engineering sys-tem of the crimping operation techno - process. The article presents a business processes sequence UML-diagram of the designing crimp matrices. The purpose of setting up the production technology, of course, is to get such sequence in which the product information will be the least time to get to the work department with the customer without re-turning to the design stage. This, in particular, requires fast and accurate automated control at the key stages of production. The authors describe in detail the interface and the operation principle of the computer-aided design software module of the crimping technological process. There are the formulas for calculating the number of crimping operations, the presentation structure of the basic data. The de-scribed algorithm allows the flexibility to assign the processes parameters of the deformation and to control the strength characteristics of the functional products. The developed software for the design of the crimping process allows the calculation of parameters such as the operation number and the sys-tematic diameters of the crimp dies. For modeling in finite element analysis system, we can use the program output data. The authors made a conclusion that the combination of the developed application software and systems of finite el-ement analysis will significantly reduce the production time and cost by reducing the time required for the design of the crimping process, reducing the sets of experimental technological tools.

The paper proposes the structure and the main automated system modules for calculating the annealing modes of glass products. There is the problem of modeling temperature fields for cylindrical products with asymmetric con-vection-radiation heat exchange with the environment and enclosing surfaces of technological equipment. The au-thor formulated the possibility of solving the two-dimensional temperature problem in the Matlab programming environment. There was the parabolic function in the performance of the temperature field-modeling problem in cylindrical glass products. This is one of the Matlab tools for solving differential equations of parabolic type with complex boundary conditions. There are the programs based on the standard fmincon function in Matlab that allow to identify the coeffi-cients of artificial convective heat exchange between the air and the product surface in each of the zones by using the determinate thermal material characteristics and the temperature-time regime parameters in the annealing fur-nace. There is a parameter identification example of the convective-radiation heat transfer in the sort glassware (glasses) annealing furnace based on the temperature field-modeling program in Matlab. The author considered the program development features associated with the need to take into account the changing initial and boundary conditions at each temperature-time stage annealing of the product. There are the program codes of the main program, the modeling temperature field functions the CilinderHolParabolic1 and the boundary conditions boundaryFileHolParabolic1. The author studied the program results and demonstrated a good match of the convective heat transfer coefficients with their physically reasonable values in artificial convec-tive heat exchange in annealing furnaces of glassware. The attained condition identification results of the convec-tive-radiation heat exchange with the environment and enclosing surfaces we can use to optimize the heat treat-ment of cylindrical products.
