Hut T. Scientific and technical bases of metrological risk management of the calibration laboratory

In the context of growing customer requirements for the quality of metrological services, the main direction of development and improving the image of calibration laboratories is to expand the scope of metrological services and modernise measurement processes in science and industry. Studies have shown that measuring and calibration laboratories face several risks that can affect the achievement of goals in the quality and accuracy of measurements. The risk management process covers various aspects of risk management, from identifying and analysing risks to assessing their acceptability and identifying potential risk mitigation opportunities through selecting, implementing and monitoring appropriate management actions. Of particular relevance is the issue of managing metrological risks as the main risks that determine the degree of controllability of measurement processes, the level of control over the accuracy of the results of these processes, and, consequently, the costs of their provision. The object of research is the processes of calibration of measuring instruments in calibration laboratories. The subject of the study is the scientific, methodological, scientific and technical principles of assessing the metrological risk of calibration laboratories. The thesis uses theoretical aspects of information and measurement technology and metrology, modelling, programming, development, research and standardisation, including in the field of metrological support of calibration laboratories. The mathematical modelling is based on solving problems of optimising the structure and functions of the control system of a calibration laboratory. The provisions of the modern theory of risk assessment, as well as the theory of measurement process control were used. The scientific novelty of the results obtained is the development and optimisation of the theoretical regulatory and technical foundations for assessing the metrological risk of calibration laboratories. The research results were used to improve the activities of the calibration laboratory. This makes it possible to increase the accuracy of calibration (reduce uncertainty) of measuring instruments and equipment.
