Condition-based maintenance policies for a combined wear and shock deterioration model with covariates

Preventive maintenance policy of single‐unit systems based on shot‐noise process

“…It would be of interest to investigate the optimal maintenance policy for multiple failure-mode systems with imperfect inspections or imperfect repair, eg,. [29][30][31][32] Because of the rapid development of sensing technologies, a condition-based maintenance schedule, eg, [33][34][35] should be more effective but more complex. Combining maintenance programs with the economic manufacturing quantity (EMQ) or inventory decision is another interesting extension for future study, since an effective maintenance policy heavily relies on the normal production process and the availability of spare components, eg,.…”

A condition-based maintenance policy for multi-component systems with Lévy copulas dependence

“…Gamma process [1,2], Wiener process [3] and Markov chains [4], to name a few. Some recent works take account for the impact of the system environment [5,6] or heterogeneity among components regarding their parameters within a population sharing the same degradation model [7,8]. However, the results of single-unit systems can be hardly extended to multi-component systems, since the existence of various types of dependences (economic, stochastic and structural [9]) affects the global optimization of system.…”

A cost effective degradation-based maintenance strategy under imperfect repair

“…In recent years, condition-based maintenance (CBM) has been widely accepted as the most efficient maintenance strategy [1][2][3][4]. Under the CBM philosophy, a system is maintained only when there is an objective evidence of impending failures.…”
