RELIABILITY AND SAFETY OF RESTORABLE SYSTEM FOR MAINTENANCE RESOURCES PLANNING

A model of a three-state technical system has been considered in the paper. The system can pass from the state of full ability into the state of safety unreliability (irreversible state) or into the state of efficiency unreliability (reversible state). The system has been described by the Kolmogorov-Chapman differential equation set. On the base of obtained equations analysis of the technical system has been done, and examples of the model testing have been presented. Obtained results and developed approach is possible to use to maintenance resources planning, optimization and management of any technical system under exploitation.
