MULTI-CRITERIA OPTIMIZATION OF REPAIR AND MAINTENANCE WORK OF COMPLEX TECHNICAL EQUIPMENT BASED ON THE UNSTEADY PARETO FRONT
An approach to solving the problem of multi-criteria optimization of maintenance (repair and preventive maintenance)is proposed Based on the application of a non-stationary Pareto front, the classification of multi-criteria optimization problems is proposed: with a critical time, with a point of no return, according to the scenario of missed opportunities, which made it possible to obtain service scenarios. The results of modeling are presented, reflecting the possibility of making decisions on the choice of quasi-optimal variants of the composition of repair and maintenance work of complex technical equipment. The aim of the work is to formulate the principle of solving the problem of multi-criteria optimization of the presentation of a complex of repair and maintenance works of complex technical equipment based on the use of a non- stationary Pareto front, which will allow taking into account cases of significant changes in the conditions for the implementation of the service process during specified time intervals.
