APPLICATION OF THE INTEGRATION METHOD TO OBTAIN A COMPLEX INDICATOR OF LABOR SAFETY

Abstract

The current state of quantitative assessment of the quality of qualimetry objects of different nature, which have different quality indicators and different measurement scales, is considered. Existing studies and publications with quantitative assessment related to occupational safety are analyzed. Harmful and dangerous factors that affect human health and performance have their own indicators and scales of different assessments. At present, there is no single approach to assessing these indicators, and a large number of qualimetric methods require in-depth scientific research on their optimality and effectiveness. The analysis proves the relevance of the topic and identifies the need to develop a methodology for obtaining a comprehensive assessment of labor safety that will be suitable for assessing working conditions at any production facility. To obtain a comprehensive indicator of occupational safety, it is proposed to determine the assessment for each harmful production factor, and then to determine a single assessment, taking into account all the characteristics. To determine the complex indicator of a harmful production factor, it is proposed to apply the integration method. The trapezoidal method is one of the methods of numerical integration. It allows calculating certain integrals with a predetermined degree of accuracy. A step-by-step algorithm for determining a complex labor safety indicator using the trapezoidal integration method is proposed. An approbation of the methodology for determining a comprehensive indicator of labor safety is proposed. The harmful factors at work are identified, the actual indicators are obtained and their estimates are determined on a dimensionless scale. A time series of changes in the indicators of harmful factors over time is graphically constructed. A comprehensive indicator of labor safety at work has been determined, which makes it possible to make managerial decisions on further actions to improve working conditions and improve the labor safety management system. The proposed methodology can be considered universal, since it can be applied to any premises and enterprise.
