It is known that domestic and foreign machine building industry have been affected by serious structural changes over the past few years. Their main point is that the part of single piece and small-lot machinery production (multiproduct engineering manufacture, MM) is up to 25–30 per cent in the total amount of machine building industry products. However, the problems of automated technological process design and automated production control are solved in the indicated production types. This is due to the fact that multiproduct machinery production systems stand out for high acceleration capacity. Moreover, transfer of batch production experience leads to significant delay of a control action and its incorrectness, and designed technologies don’t count a production system state. The bailout plan is possible in the case of information integration of technological process design automation systems and automated technological process control systems. In this regard automated technological process control systems must provide a possibility to correct production plans at all levels quickly. The paper shows relevance of the proposed concept of information integration of automated systems of technological process design and control in a multiproduct manufacture. The research is based on the system theory framework and the product life cycle methodology. The authors examine the hierarchy of the systems and explain the principles of creating integrated systems and their subsystems. They also suggest the decision-making method for technological process design and control in hybrid systems.

The paper considers the problem of exact distribution of the variation coefficient, the statistical characteristic used for analyzing random variable measurements, the fluctuations in technological processes for production of materials, semi-finished products, machine parts and structural elements, as well as for studying scattering of mechanical properties, es-pecially under variable loads. The importance of the variation coefficient is also determined by the fact that it is one of the design parameters for justification of reliability, durability and life. Safe operation of machines and structures largely depends from the reliable determination of this coefficient. The exact distribution of the variation coefficient for normal population is obtained based on the well-known theorem on the distribution function of the ratio of two random variables. In this case, it is a sample mean square deviation having the chi-square distribution and the sample mean with the normal distribution law. The obtained exact formulas for the variation coefficient distribution were verified by multiple statistical modeling by the Monte Carlo method, which has confirmed the accuracy of analytical calculations. In order to simplify practical calculations, the authors consider an approximate model that has shown an error of no more than 1,5 % for observational volumes from 3 to 20. The paper considers the estimation examples of confidence limits, failure-free operation probability and other reliability problems based on the obtained solutions.

3. Tools for determining a linguistic-statistical affinity of languages using the turkic morpheme model [№1 за 2018 год]

The article proposes a new approach and tools for linguistic-statistical comparing of Turkic languages affinity using the Turkic morpheme model. This model is a structured description of Turkic morphemes, which consists of morpheme properties and their manifestation contexts at all language levels (phonological, morphological, syntactic and semantic) [3, 5]. The tools determining the linguistic-statistical affinity of Turkic languages is implemented as a web resource that processes information about the language represented in the morpheme model database. Comparing the affinity of languages by linguistic-statistical methods using the Turkic morpheme model can be made at different lan-guage levels: morphological, syntactic, lexical. The paper describes four following methods: comparing the number of affixational mor-phemes corresponding to a grammatical category; comparing the number of allomorphs in one morpheme; comparing the joined-up and separate writing of morphemes; comparing the order of affixational morphemes within the word form. Nowadays the model database is filled up for Tatar, Kazakh, Crimean Tatar, Turkish and Uzbek languages. It allows comparing linguistic-statistical affinity of the languages in pairs. The proposed method can be used to compare language morphologies to obtain information on the affinity of dialects to a literary lan-guage, as well as to detect the affinity of one language dialects to dialects and a literary language of other languages. Our methodology and tools can be used not only for Turkic languages, but for any closely related languages of the agglutinative type.

During information aggregation on highly dynamic objects in a collection and processing hierarchical system, calculations and of data flows asserts selection of aggregation algorithms relevant by characteristics to a state of the environment. In order to provide a selection it’s necessary to compare different algorithms not only by the characteristics, but also by the output. The article makes an analysis of the existing approach and proposes to compare aggregation results by comparison of fuzzy preference relations formed on the stage of revealing object allocation in a feature space. There is a formalization of the approach to comparing algorithms output and the requirements to the index which forms its basis. The idea of the approach is in calculation of the distance between reflections of fuzzy binary preference relations in multidimensional space, which are formed by the basic algorithm and the algorithm under comparison. The paper provides the order of implementation of this operation. The implemented design ratios are justified. The paper presents the composition and the structure of aggregation algorithms comparison software tools. It also shows the possibility of applying the index from the approach as the specification of functional quality of the variant of the aggregation algorithm when comparing it with the reference variant.

The purpose of the work is to develop a software system for assistance in experimental research on a new out-of-roundness measurement method. One of the important aims of the research is to learn the main measurement error of this method. The Samara branch of the Lebedev Physical Institute of the Russian Academy of Sciences has developed a laboratory layout of the device. Now the Samara University uses it in the training process and updates it further. The method assumes that a focused laser beam scans the controlled surface, while a mirrored laser beam position is determined (Patent RF 2109250). Its practical application is controlling the deviation of a bearing inner ring tread form. The functions of the research software system are the following: acquiring pre-processed data from external files; calculating a radial profile, out-of-roundness and waviness after a single scan; statistical analysis of these measurement results by rescans series data and estimation of the coordinate measurement error in each point of a profile. According to the preliminary results of the measurement series analysis, its estimated basic error is 0.07 m for out-of-roundness and 0.05 m for waviness without considering the cinematic error during scanning. These results compare well with ones that currently used instruments give, such as interferometers and contact circular meters, in the practical application considered here. Measurement error is mainly caused by kinematic inaccuracies during operating a turning sub-unit for the controlled object. The conclusion implies that the device laboratory layout still needs updating and its metrological characteristics can be improved. Taking into account the lack of funding in the research, it is suggested to acquize and pre-process data in places where it is possible to do, whereas perform further calculating in the cloud.

The paper presents a conceptual basis for developing training prototypes of an interactive assembling system for automatic building of application software systems. This basis was obtained during practical works in such courses as “Software systems design and architecture” and “Object-oriented analysis and design”. Software systems generation is based on the Theory of program schemes concepts, its standard structural schemes and program engineering methodologies. Assembling occurs in user interaction on a professional language. The professional dialogue language is based on the concept of intellectual interface and comprises a combination of a strictly programmed dialogue and a free scripted dialogue. The purpose of the system is practical demonstration of basic stages and operations when developing complex software according to a layout-modelling approach to software engineering briefly summarized in the paper. The paper also includes formulations and solutions for some important problems of complex software systems generation, such as program module compatibility, formalization of computer interaction and choosing formal models for human-machine interface. The authors propose a specific system architecture that allows expanding the system with process plugins when collecting incompatible software modules, which are written in different languages and require diverse libraries, to make them compatible. The paper presents systemized formal and informal models of human-computer interaction. In addition, there are three training prototype implementations for selected models: model based on the game theory, a tensor network model and a graph-based model.

The paper presents a developed automated system for construction and geodynamic visualization of virtual tourist routes. The system is designed to increase the effectiveness of the decision support process when planning a tourist trip. The route in the software system is presented as a virtual tour containing an equidistant projection of panoramic video records with ref-erence to the terrain coordinates on an electronic map. The system provides dynamic 3D-visualization of a route in a web-oriented applica-tion with the SaaS architecture. The addition to the tourist dynamic video route on an electronic map displays static tourist (historical) ob-jects, also attached to map objects and equipped with a semantic characteristic (text, photos, links to Internet resources, audio recordings). The paper describes the concept of development of a system logical model based on a domain, a general structural system scheme, ap-plied interface modules, tools of connected libraries, software tools and algorithms of functioning. Interaction with the main loaded data in the system occurs using software functions implemented based on computer vision algorithms and image processing using the OpenCV li-brary. The system is based on the ITSGIS geoinformation platform and uses the specialized WayMark software to process the initial data received from mobile geo video laboratories: navigation coordinates, images and video from several cameras. The functionality of the system solves direct tasks of numerous tourist organizations. However, potential consumers of the system should be not only them, but also individuals who travel independently. The developed system provides the formation and visualization of a virtual tourist route and enhances the information mobility of tourists. The system provides search functions for geo video routes according to the following criteria: a minimum route time, a number of points of interest, a minimum or maximum distance.

The system is intended for organizations authorized to initiate and examine cases of administrative offences. The paper describes the developed information-logical project, the architecture, program modules and functional capabilities of the developed system. The system provides the formation of documents and reports necessary to keep records of administrative cases. The system controls the procedural terms of production, forms a task calendar for each user of the system. The system provides decision support in the proceedings on administrative offenses. The paper describes an integrated mathematical model of decision support based on the ontological knowledge representation model and Case-based reasoning technology. It describes the use of precedents (patterns) to solve similar problems in knowledge bases. The approach to pattern reasoning implemented in the system uses both general knowledge of the subject area, the same sort of situations and solutions, and specific data and conclusions from concrete situations (patterns). The decision on the task is made by finding a similar situation in the past and using the taken decision. It is expected that the application of scientific and practical results based on the results of the work will increase the effectiveness of organizations involved in the process of proceedings in administrative cases.

The balance between duration of open and traditional training depends on the adequacy of computer training systems and telecommunication capabilities. It is important to note that technical costs of telecommunication means can reduce the adequacy of computer training systems in network performance. The main reason of the conflict between the as-sessments of proficiency levels of operators who trained at computer training systems and at standard equipment are unaccounted skills caused by the inadequacy of computer training systems in relation to standard equipment, which leads to a conflict of determining curricula. Consequently, the paper presents software for an automated training control system for operators of ergotechnical electronic equipment. The software consists of separate modules. There is a possibility of their expansion and modernization. The software for operators’ training planning and evaluation of equipment adequacy allow creating individual training curricula for electronic equipment operators by the minimum cost criterion. The program of defining a system relations structure (Schedule TR) allows automating the analysis of application conditions of systems for various purposes and identifying individual learning plans for a particular specialist. The program of evaluating the adequacy of the automated information system of developing an ergotechnical complex, which has the Adequacy TR hierarchical structure, is based on the remote survey using telecommunication means for trainees who completed the training course, which included computer training systems and standard equipment. The program of defining meaningful components of training exercises and training plans is developed to automate the correction for selected operations and specified RF conditions of operating radio electronic means of appropriate curriculum meaningful components. According to selected training means and the number of trainings on each training tool, it corrects appropriate meaningful components of a curriculum during training of operators. The program “The system of objective operating control of actions of DIA information system operators” provides an operational objective control of operators’ action. The training planning control program for specialists of ergotechnical systems (“Information conflict-proof automated system for rational planning of practical training for operators of DIA radio electronic objects”) allows automating operators’ training management using the computer training systems.
