В статье рассматривается проблема создания автоматизированных систем, удовлетворяющих требованиям современного производства (универсальность, многофункциональность и комплексность), прежде всего, должны быть созданы специальные методология и теория, раскрывающие процессы проектирования, представляемые в математическом, формализованном и программном виде. Авторами предлагается формализация процесса проектирования и технологии, на основе которой создана система автоматизации проектирования, что позволит проектировать технологические процессы (ТП) для разнообразных изделий, в том числе ранее не производившихся. Разработка математических моделей ТП механической обработки деталей обеспечит объективное принятие технологических решений и будет отражать динамику качественного и количественного преобразования заготовок в процессе производства. Практической значимостью работы является создание и апробация ПО «Система автоматизированных рабочих мест машиностроительных предприятий», в которой разработаны АРМ технологических служб и подразделений, а именно АРМ отдела технолога. Для реализации цели, разработанный АРМ обеспечивает выполнение двух основных направлений деятельности. Во-первых, обеспечивает возможность разработки и внедрения ТП, средств автоматизации и механизации, оптимизации режимов работы универсального оборудования, и оборудования с числовым программным управлением. Во-вторых, реализует своевременную разработку технических заданий для обеспечения структурных подразделений (цехов, участков) специальной оснасткой, инструментом и приспособлениями, предусмотренными технологией, нестандартным оборудованием средствами автоматизации и механизации. В результате проведенных исследований, получены: 1. Методика проектирования основных этапов ТП изготовления деталей, основанная на объективных критериях выбора технологических параметров, что обеспечит исключение ошибок на начальном этапе. Разработан общий алгоритм решения технологической задачи. 2. Методика назначения переходов и составления планов обработки, в основу которой положен принцип выполнимости определенным методом текущего перехода, а именно, выполнение характеристик. 3. Методика оснащения ТП позволяет учитывать геометрические и точностные параметры, дополнительные требования к поверхности на конкретных стадиях с учетом текущей производственной ситуации. The problem of development special software for the automation for design of technological processes that meets the requirements of modern production – universality, multifunctionality and complexity are considered.

The issues of failure risk diagnosing were actualized in Ukraine against the background of transformation processes in the economy. Enterprises are particularly vulnerable due to the forced reorientation to new markets and changes in permanent business relations. Therefore, it is now important to identify in insolvency problems and the risk of enterprises’ failure of this industry. The purpose of the research is to substantiate the method of selection and form a system of indicators that will provide diagnostics of the failure risk based on the financial statements of the company. The subject of the research is the Ukrainian machine-building enterprises and the process of forming a system of indicators, which will determine the failure risk of business entities. The methods of the research: methods of scientific knowledge, such as analysis and synthesis, induction, measurement, observation, formalization, logical and analytical techniques, as well as the methodological apparatus of financial analysis and mathematical statistics. The hypothesis of the research is the assumption that the process of selecting indicators based on the methods of mathematical statistics will avoid bias of other shortcomings that reduce the quality of enterprises’ failure diagnosing. The statement of basic materials. The existing models of failure diagnostics have serious shortcomings in terms of the approach to the selection of indicators and the number of classes, which the enterprise may belong to, depending on the existing risk of bankruptcy. Therefore, the authors proposed their own approach to the selection of diagnostically significant financial ratios based on the Student's t-test, the Mann-Whitney U-test and the correlation coefficient. A system of indicators of failure diagnosing has formed based on this approach. The originality and practical significance of the research is that a system of indicators is mathematically substantiated, what corresponds to the modern principles of evidence-based research and maximally emphasizes that the machine-building enterprise belongs to a particular failure risk class. Conclusions and perspectives of further research: the researchers are going to build a failure diagnostic model for Ukrainian machine-building enterprises based on the determined system of indicators.

Relevance of research. The actualization of the assessment of the financial condition of the enterprise from the standpoint of possible bankruptcy is indisputable, taking into account the impact of both external and internal factors on the work of the enterprise. The purpose of the study: to develop a methodological approach to preventive assessment of the financial condition of the enterprise, taking into account internal and external factors influencing its economic activity from the standpoint of possible bankruptcy. Methodology and scientific methods: methods of comparative analysis, economic-mathematical modeling, system approach are used. Research results: the article considers scientific trends and problems of assessing the financial condition of enterprises using different methodological approaches. The most well-known formed discriminant models of foreign and domestic scientists are characterized, taking into account their advantages and disadvantages in conducting economic assessment of the financial condition of enterprises. Features and possibilities of application of these models at the domestic enterprises of a machine-building complex are stated. The necessity to develop a dynamic operational model of preventive management is substantiated, which makes it possible to take into account both internal and external national factors and foreign indicators. Unlike the existing ones, this model considers not only financial indicators (profitability ratio, current liquidity ratio, asset turnover, autonomy ratio), but also their importance in the dynamics, as well as taking into account external factors of the country in which the company operates. A new methodological approach for assessing the financial condition of the enterprise with the inclusion of national factors of enterprises and performance indicators of foreign economic entities is proposed. The proposed method of assessing the company in the dynamics in relation to each time to the previous year in terms of bankruptcy characterizes the effectiveness of management and is a signal to take precautions regardless of the stage of the life cycle of the enterprise or its products. The information support of this model serves as a basis for the formation of the company's self-management system. Research framework / possibility of using the results: the proposed methodological approach has an international character and can be used by single-industry enterprises of different countries to assess their financial and economic, marketing, organizational, production, logistics activities, especially when looking for business partners. Practical significance: assessment of the bankruptcy probability index at 12 machine-building enterprises of Ukraine was carried out, conclusions were made on the location of enterprises in the bankruptcy zone. Social consequences: the results of this assessment lead to management decisions by the management of machine-building enterprises on the optimization of jobs, labor movement, internal and external staff rotation.

The article is devoted to reengineering of technological processes - a method of their qualitative transformation on an innovative basis, which in turn assumes the availability of tools that make it possible to establish the economic efficiency and technical capability of such transformations of construction production, to identify the effect of their implementation. In this regard, the problem of forming a parametric model of reengineering of construction technological processes, which involves four enlarged groups of indicators that reflect the quantitative and qualitative characteristics of the processes: materials used, working time, machine time, spatial organization, is considered. It is established that parameters can have either an absolute (physical, cost) or relative (point, percentage) expression and also make their own decomposition. The practical significance of the provisions given in the article is determined by the development of methods of technical rationing, which leads to a reduction in the cost and duration of construction.
