The article considers the issue of establishing a mathematical dependence in the form of an S-shaped curve for quantifying the quality of buildings and structures at hazardous production facilities with subsequent automation of the quality assessment calculation mechanism based on the obtained mathematical model. It is proposed to take a piecewise nonlinear dependence described by a polynomial of odd degree as the basis of an S-shaped curve. Using the least squares method, the equation of the S-shaped curve of the quality assessment M from the value of a single quality indicator p_(i ) is obtained. The software «Qualimetric Unit Quality Estimation» has been developed, which allows to carry out a quantitative assessment of the quality of a single indicator by the method of qualimetry, as well as to give a direct visual representation in the form of a graph. The process of calculating the quality assessment of the selected single indicator reduces the time for calculating and analyzing the results, increases the efficiency of the procedure for assessing the quality of materials, products, structures of buildings and structures at hazardous production facilities.

The paper presents the results of the study aimed at improving the quality of specialists training in higher educational institutions who will fork for industrial enterprises where hazardous production facilities are operated. The quality of training depends on the level of industrial safety of hazardous production facilities and as a consequence the likelihood of accidents. At the moment, despite the general trend of reducing accidents at hazardous production facilities over the past ten years, their number remains quite significant. At the same time, social and economic damage from accidents can be estimated at 600-700 billion rubles per year, which will have a negative impact on the economic stability of the Russian Federation. The obligations of industrial enterprises where hazardous production facilities are operated and its employees are defined by the legislation. The content of education should take into account these basic requirements, which should be formed into separate themes. Accordingly, the modular principle is used in the design of the training content. The development of content in the form of modules will ensure the organizational and substantive unity of students training. We accept lectures and practical classes, as well as group and individual ones as the main methods of the educational process. Learning the material based on the results of lectures, practical training and self-training should allow students to form the qualities specified in our profesionogram. How the educational material proposed for study is learned should be checked during the control activities, starting from the initial-input control and ending with the final control.

Introduction. The article considers the problems of industrial injuries and accidents at gas supply facilities. Hazardous production facilities are characterized by an increase in accidents and injuries among workers. The article considers the peculiarities of occurrence of accidents and injuries in the operation of hazardous production facilities. Problem Statement. The purpose of the study is to analyze the statistics data and the materials of investigation of accidents and emergencies in hazardous industries, to determine the characteristic causes of injuries at work. Theoretical Part. The statistics on accidents and injuries during operation of gas facilities provided by the Federal State Statistics Service are used as basic information. Conclusion. The results of the analysis show that the main causes of accidents and emergencies are the causes associated with the human factor and equipment malfunctions. In order to improve safety and prevent injuries among workers, it is necessary to introduce an integrated approach and risk assessment, which will take into account all the factors and conditions that contribute to the occurrence of accidents and injuries at gas supply facilities.

Maintenance is a complex, extensive and important issue in terms of its impact on the quality of manufactured products or services provided in all areas of industry. The importance of predictive maintenance for the industry in the 21st century is crucial. However, the right approach to maintenance management is often underestimated in many companies today, although it can have a very positive effect on the company’s efficiency. Using the example of a practical application, the paper includes a comparison of three main maintenance concepts – classical (reactive), planned, predictive through the simulation software Witness. Maintenance concepts are compared in terms of their ability to solve and eliminate failures that occur in production facilities during operation.
