Maintenance Scheduling: Issues, Results and Research Needs

Abstract

Productivity, based on estimated and actual hours, of most maintenance workers is only 30 to 50 per cent. Given the significance of maintenance to manufacturing competitiveness, it is surprising how little research is being carried out. Scheduling is a crucial component of maintenance management and is a focus of research. Identifies the areas of concern in maintenance scheduling and surveys representative work from the academic and practitioner literature. Specific points of practice and theory which need further investigation are pinpointed.

Production/maintenance cooperative scheduling using multi-agents and fuzzy logic

“…Paz and Leigh 1994). Their classi®cation may vary according to the chosen criterion, but the following categories are usually de®ned.…”

“…Scheduling maintenance activities is a problem on its own: the duration of the maintenance activities may be imprecisely known (Paz and Leigh 1994) and the beginning date of a preventive maintenance activity may be brought forward or postponed in comparison with the optimal date (Gits 1994). Many studies have been done on the composition of maintenance teams, like Basker and Husband (1982) and Barnett and Blundell (1981).…”

Maintenance Scheduling: Description, Status and Future Directions

“…However, simulation appears to be the most significant [45,57,75,83]. Furthermore, among the general MS studies is the work of Anily [1,2], Dillon [24], Contaxis et al [17], and others [26,30,62,65,68,80,88]. There are also numerous studies on simultaneous scheduling [40,44,66].…”

Spare Parts Planning and Control for Maintenance Operations

“…Furthermore, repair shops often perform repairs for many different repairable types. Consequently, repair and overhaul of spare parts is usually a labor intensive process (Paz and Leigh, 1994). Shops that deal with repairables are usually referred to as repair shops, whereas the shops deal with rotables are usually referred to as overhaul shops.…”

“…The objective is approximately met by formulating the problem as a binary integer program and using rounding procedures to find feasible solutions. Paz and Leigh (1994) give an overview of many different issues involved with maintenance planning and review much of the literature from before 1993. They identify manpower as the critical resource that has to be reckoned with in maintenance planning.…”
