OPTIMISATION OF THE TECHNICAL OBJECT MAINTENANCE SYSTEM TAKING ACCOUNT OF RISK ANALYSIS RESULTS

The article presents the author's original method of optimisation of the technical object maintenance system taking account of risk analysis results. An original form of the objective function was formulated, in which a risk measure model based on two criteria was used. RBM methods were discussed and technical object maintenance methods/strategies were reviewed, with their most important characteristics pointed out. The process of making maintenance-related decisions is armed with procedures based on a risk valuation pattern. The author's original risk valuation pattern was presented and special cases resulting from the use of such patterns were discussed. Dynamic programming was used to solve the problem of optimisation. The author's original mathematical model of the method of optimisation was developed and presented, and its four-stage calculation algorithm was presented in detail. Based on the collected statistical data on damage, hazard analysis and risk assessment procedures were carried out. Using computer implementation of the optimisation model, an experiment in planning the maintenance of the technical objects examined was carried out and the results of the optimisation experiment were presented.
