The article proposes a qualimetric method for assessing the quality of such hazardous production facilities of a metallurgical enterprise as special bridge metallurgical cranes. The supporting structure of the crane is investigated, structurally divided into four main groups of structures and fifteen elements, which carry all the information about the dominant properties of the operation of the crane. Two indicators of the quality of the crane structure were introduced: complex and integral. For a complex function, the probability density function of the reliability levels of structural elements in the form of a uniform law is taken. For integral - an indicator of the risk of an accident, since most of the cranes under consideration are operated outside the warranty period. The obtained quantitative data on the reliability levels that structural elements should have is valuable. The investigated qualimetric method will allow experts to make the right scientific and technical decisions and, ultimately, will bring a significant economic effect that can be comparable to the price of a new crane and its commissioning. Special cranes of the Magnitogorsk Metallurgical Combine were considered. The article continues to develop studies of qualimetric science for assessing the quality of products and various objects of a metallurgical enterprise of the scientific school of the Magnitogorsk State Technical University named after V.I. G.I. Nosov.

Risk assessment is an integral part of an enterprise's quality management system. The risk of low quality products is the most significant risk, as it is directly related to the concept of enterprise competitiveness. The paper analyzes the scientific papers related to the assessment of the quality of products, processes and services, their disadvantages, possible limits of application. It is proposed to use mathematical dependences to obtain estimates of product quality indicators on a dimensionless scale. Knowing the density function of random variables of product quality indicators and knowing the mathematical dependence of their estimates on a dimensionless scale, it is proposed to obtain the density function of estimates. Knowing the function of the density of estimates of quality indicators, it is proposed to find the probabilities of risks of the assessment of quality indicators in any given interval on a dimensionless scale. A method for assessing the risks of low quality products has been developed

In connection with the growing use of polymer composite materials all over the world and in domestic aircraft construction in civil aircraft of the transport category, the analysis of forecasting methods of their application at the main stages of the life cycle of this class of structures becomes an urgent problem.Efficiency, as the ratio between the achieved result and the resources spent on its achievement, can be interpreted as the ratio between the total quality indicators of the created object and the total costs.However, quality indicators are such metrological characteristics, the quantitative measurement of which in most cases is difficult or almost impossible. In this regard, the qualimetric quality indicators acquire the qualimetric form of qualitative characteristics. Qualimetric characteristics make it possible to operate during their analysis by a productive method of expert assessments of criteria for the implementation of any object, including composite structures of aircraft aggregates. As a criterion for predicting the effective volume of use of composite structures, an analogue of D.L. quality at the stages of their life cycle. The numerical values of each level of the stages of the life cycle are assessed by an expert according to the proposed five-level general identification tables with the subsequent summation of the criterion indicators by stages of the life cycle, making it possible to determine both the efficiency of using composites at individual stages and its integral value for all main stages. The relative value of the efficiency criterion can be represented in monetary terms by multiplying it by an equivalent established on the basis of metrological (qualimetric) methods and means of assessing the results of a particular production.

Нарастающие катастрофические сценарии последствий глобального потепления определяют актуальность оценки углероддепонирующей способности планетарной растительности. Поэтому исследование структуры и квалиметрии биомассы древесных и кустарниковых растений имеет важное значение. Проанализировано несколько методов неразрушающего контроля древесины, каждый из которых имеет свои ограничения, и представленный краткий их анализ может способствовать выбору вари- анта, наиболее пригодного для того или иного метода неразрушающего контроля. Дан анализ состояния проблемы квалиметрической оценки фитомассы деревьев как сырья в промышленном производстве, так и в селекционных программах. Показаны возможности квалиметрической оценки древесины путем лазерного зондирования. бортовое и наземное лазерное сканирование дает с высокой точностью характеристики структуры дерева и древостоя, которые связаны с плотностью древесины. Разработка картографических продуктов по географическим градиентам в сочетании с возможностями дистанционного зондирования локальных структурных показателей древостоев обеспечивает поддержку мелкомасштабного картографирования плотности древесины. Дана характеристика впервые составленной базы данных о квалиметрии биомассы лесообразующих пород центральной Евразии и показаны перспективы ее использования. The increasing catastrophic scenarios of the consequences of global warming determine the relevance of the assessment of the carbon-depositing ability of planetary vegetation. Therefore, the study of the structure and qualimetry of the biomass of woody and shrubby plants is important. Several methods of non- destructive testing of wood are analyzed, each of which has its own limitations, and the presented brief analysis of them can contribute to the choice of the option most suitable for a particular method of non-destructive testing. The analysis of the state of the problem of the qualimetric assessment of the tree phytomass as raw materials in industrial production and in breeding programs is given. The possibilities of qualimetric assessment of wood by laser sensing are shown. Airborne and ground-based laser scanning provides high-accuracy characteristics of the structure of the tree and the stand, which are related to the density of the wood. The development of cartographic products based on geographical gradients, combined with remote sensing capabilities of local structural indicators of stands, provides support for small-scale mapping of wood density. The characteristic of the first compiled database on the qualimetry of the biomass of forest-forming species of central Eurasia is given and the prospects for its use are shown.

Full textAbstract:
Дипломна магістерська робота присвячена питанням щодо розроблення системи кваліметричного оцінювання складних технічних систем з урахуванням вимог міжнародних стандартів стосовно її якості та безпеки. В роботі проаналізовано методи кваліметричного оцінювання, показано різницю між поняттям "вимірювання" та "оцінювання". Доведено, що ці два поняття доцільно використовувати для процедур кваліметрії, які теоретично кваліметричні вимірювання складаються з двох етапів: вимірювання показників (властивостей) та оцінювання рівня якості. До основних характеристик складних технічних систем віднесено якість та безпеку, які обумовлюються як вимогами нормативних документів, так і задоволеністю потенційних споживачів. Тобто вимагають як якісного, так і кількісного оцінювання. Доведено, що поєднання методології кваліметрії та метрології суттєво розширює можливості щодо забезпечення єдності вимірювань, підвищення точності та достовірності отриманих результаів. Запропоновано класифікацію методів кваліметрії за такими ознаками, як показникики якості та джерело отримання інформації. Згідно даної класифікації методи поділено на об’єктивні еврестичні, комбіновані. Для досягнення умов ефективності безпеки складної технічної системи запропоновано використовуати матрицю розгортання функції безпекового показника якості. Для його визначення наведено методику оцінювання невизначеності результатів експертних вимірювань, в основу якої покладено професійну та кваліметричну компетентність експерта.The master's thesis is devoted to the development of a system of qualimetric evaluation of complex technical systems, taking into account the requirements of international standards for its quality and safety. The paper analyzes the methods of qualimetric evaluation, shows the difference between the concept of "measurement" and "evaluation". It is proved that these two concepts should be used for qualimetry procedures, which theoretically qualimetric measurements consist of two stages: measurement of indicators (properties) and quality level assessment. The main characteristics of complex technical systems include quality and safety, which are determined by both the requirements of regulatory documents and the satisfaction of potential consumers. That is, both qualitative and quantitative evaluation are required. It is proved that the combination of qualimetry methodology and metrology significantly expands the possibilities for ensuring the uniformity of measurements, improving the accuracy and reliability of the results. The classification of qualimetry methods according to such features as quality indicators and source of information is proposed. According to this classification, the methods are divided into objective heuristic, combined. Proposed to achieve the safety conditions of a complex technical system, it is proposed to use a deployment matrix of the safety quality function. To determine it, the method of estimating the uncertainty of the results of expert measurements is based on the professional and qualimetric competence of the expert.

Full textAbstract:
The article presents the results of research for the mathematical model for estimating the probability of risk of incompetent specialist graduation. The mechanisms and tools to determine the probability of risk of incompetent specialist graduation have been developed in the course of the research. The goal tree method has been used as a mechanism to determine the relationship between the structural components of the educational process and the educational program. Using this method, the structuring of 9 criteria by which the educational program quality is evaluated has been carried out. That is, its strengths and weaknesses have been identified. In turn, as a tool for estimating the probability of an educational process (educational program) risks and the graduation of an incompetent specialist, it has been proposed to use a regression mathematical model. To build a mathematical model, an active experiment, a qualimetric approach, a method of regression analysis, and 16 conditional educational programs that met the "Standards and Guidelines for Quality Assurance in the European Higher Education Area" (ESG) have been used. The construction of the model has been carried out according to a specially designed scheme, which included 5 stages. In the first stage, a group of experts was formed and their consistency was determined with the help of the "HEI Experts" software. In the second stage, six groups of indicators were identified, which further estimated the educational process (educational program) quality. For this purpose, the experts used the method of pairwise comparison to select 9 unit indicators, which further estimated the levels of compliance of 16 conditional educational programs. The estimation was conducted according to standardized quality indicators that are inherent in the real educational process (educational program). In the third stage, a robust plan of the experiment was constructed using the method of pseudo-random LP-τ numbers uniformly distributed in multidimensional space. According to the plan, a working matrix of the experiment was formed. Then, the group of experts formed in the first stage carried out the percentage estimation of the probability of risk of incompetent specialist graduation. In the fourth stage, a mathematical model was built using the PRIAM (planning, regression, and model analysis) software. This model allows us to assess nine factors that affect the probability of risk of incompetent specialist graduation. In the fifth stage, the statistical characteristics of the model were tested. According to the test results, it was proved that the model is informative, adequate, and stable, both in terms of structure and calculations. At the same stage, the marginal surfaces were constructed and the forces of influence of regressors (indicators) on the probability of risk of competent/incompetent specialist graduation were determined. According to the results of research, it has been proved that such indicators as compliance of the applicants (bachelors) level with the second Master's level and the level of considering labor market employers (stakeholders) requirements have the strongest impact on the competence of the future specialists. The proposed model allows us to estimate the factors influencing the efficiency (effectiveness) of the educational process and to determine the probability of the risk of competent/incompetent specialist graduation.

Full textAbstract:
The problem of the safe interaction between a Nuclear Power Plant (NPP) and a Power Grid (PG), considering the Fukushima nuclear accident, is becoming topical. There are a lot different types of influences between NPPs and PG, which stipulate NPPs’ safety levels. To evaluate the influences, two metrics are proposed: linguistic and numerical. The approach to the NPP-PG safety assessment is based on the application of Bayesian Belief Network (BBN), where nodes represent different PG systems and links are stipulated by different types of influences (physical, informational, geographic, etc). It is suggested to evaluate criticality of the PG system considering the change of criticalities of all connected systems. The total criticality of each node in BBN is assessed considering particular criticalities caused by different types of influence. The complex nature of NPP and PG mutual interaction calls for the need for integration of different methods that use input data of different qualimetric nature (deterministic, stochastic, linguistic). Application of one specified group of risk methods might lead to loss and/or disregard of a part of safety-related information. BBN and Fuzzy Logic (FL) represent a basis for development of the hybrid approach to capture all information required for safety assessment of NPP – PG under uncertainties. Integration of FL-based methods and BBNs allows decreasing the amount of input information (measurements) required for safety assessment, when these methods are used independently outside from the proposed integration framework. An illustrative example for the NPP reactor safety assessment is considered in this chapter.
