Optimal preventive maintenance with repair

Risk-based maintenance modeling. Prioritization of maintenance importances and quantification of maintenance effectiveness

“…Table 2. 5 shows the top 55 basic events prioritized by their risk reduction importance. Table 2.9 contains the more complete prioritization.…”

Availability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval

“…Preventive maintenance (PM) is the scheduled maintenance that includes actions such as; adjustments, inspection, lubrication and replacement of components (Sim and Endrenyi 1988). Ahmad et al (2011) proposed a maintenance decision model for PM application.…”

Techniques for Optimal Maintenance Scheduling

“…It is therefore important to study the particular situation under operation. It is evident from the above that there are two main categories of jobs, that is, emergency and scheduled maintenance [1,2,6].…”

“…Their responsibility is to perform unscheduled (emergency) repair work anywhere in the system and scheduled preventive maintenance of the components of the system. The two actions may be grouped as on-site maintenance [2]. The objective of work scheduling is to ensure that the maintenance operations are carried out at an optimum level [3].…”

“…The maintenance of any engineering system consists of performing three main functions which include [1,2]:  Corrective maintenance, consisting of recognition or detection, location or diagnosis, correction or repair/replacement, and verification or checking of scheduled, emergency failure of components or equipment.  Setting up and performing scheduled periodic preventive inspections, replacements or repairs.…”
