ВИЗНАЧЕННЯ ЗУСИЛЬ ПРИ ПРОКОЛЬНІЙ НАДВИЖЦІДВОПРОЛІТНОГО НЕРОЗРІЗАНОЇ ПРОЛІТНОЇ БУДОВИ

Variations of stresses in cross-sections of a launching girder and a span at all stages of its longitudinal shifting are investigated in the paper.В статье отслеживаются изменения усилий в сечениях аванбека и пролётного строения на всех этапах его продольной надвижки.В статті відслідковуються зміни зусиль в перерізах аванбека та прогонової будови на всіх етапах її поздовжнього насування

Mathematical modelling of professional risk at Ukrainian metallurgical industry enterprises

Purpose: To develop a more advanced methodology, the application of which will provide an informational and computational and analytical basis for planning and implementing effective preventive measures aimed at minimizing occupational risks with limited resources, as well as in the absence of organizational and technical capabilities to create absolutely safe working conditions. Design/methodology/approach: For the study, statistical data were used that obtained from enterprises of the metallurgical industry of Ukraine. Research methods: analysis and generalization of known scientific results, methods of statistical analysis, mathematical modelling, expert assessments and decision theory. Findings: The results of experimental studies have confirmed the possibility of an objective assessment of various options for the OSH management strategy, which allows justifying the allocation of funds for OSH in the required amounts. It is shown that professional risk management strategies are characterized by different efficiency in the use of available financial resources, and the most effective strategy is one that allows you to minimize the level of risk (in comparison with other strategies) with the same amount of funding. Research limitations/implications: The study focuses on enterprises of the metallurgical industry in Ukraine. Practical implications: The application of the developed mathematical models demonstrates the effectiveness of financing certain preventive and protective measures, and stimulates the head to ensure industrial safety. Originality/value: The developed mathematical models allow justifying the allocation of funds for OSH in the required amounts
