“…When a breakdown occurs [50] (criteria DR 131 , DR 121 , DR 122 , DR 123 , DR 124 , and DR 124 ), reinstating the equipment depends on the competence of the workforce [51,52] (criterion FR 143 ) and the maintenance resources [53,54] (criteria DR 111 , DR 112 , DR 113 , DR 114 , and FR 123 ) available to the maintenance team. Encouraging a philosophy of reliability (criterion FR 134 ) among team members assists to establish the measures [55,56], for instance, mean time to restore (criterion FR 121 ), mean time between maintenance (criterion FR 124 ), mean time between failures (criterion FR 122 ), the number of defective products (criterion DR 132 ), maintenance workforce cost (criterion FR 111 ), spare parts cost [53,54] (criterion FR 112 ), overhead cost (criterion FR 113 ), and consultancy cost (criterion FR 114 ) are constantly tracked and enhanced while adopting the most appropriate maintenance strategy for the rolling mill plant [53,54]. Furthermore, the decision-maker needs to implement strategies to minimize maintenance time [57,58] (criteria DR 113 , DR 121 , DR 122 , DR 123 , DR 124 , and DR 133 ) and permit the plant to function at the uppermost efficiency (criterion FR 123 ) that it can.…”
