Abstract
Aim. The paper aims to develop and test a methodology for quantifying the risk of equipment damage due to operator errors whose frequency depends on their work experience. Methods. The authors use applied methods of sociology (questionnaires, expert assessment) and risk analysis to obtain quantitative dependences of the risk of damage on the work experience. The above methods involve classifying the possible operator errors in the form of equipment operation violations, an expert assessment of the frequency of such violations depending on the operator’s work experience. By decomposing the equipment we define a set of components, for which expert assessments are obtained of the risk of damage for classified operation violations. Ultimately, the risk is assessed as the product of the frequency of operator errors (classified violations of the rules) and the probability of damage to the equipment components. Results. The method was tested by collecting expert information and quantifying the risk of damage to the components of the power structures of working equipment of mining excavators in case of violations by the operator of the rules of operation. Conclusions. It is proposed to use expert assessments of the effect of an operator’s work experience on the risk of equipment damage to solve a number of applied problems, i.e., substantiation of the frequency and scope of scheduled and emergency diagnostics and maintenance operations, identification of the operator errors to be – above all else – eliminated by improving the quality of professional training.
