Abstract

The aim of this research is to propose optimization models for repairs’ scheduling and sequencing of different failure types to multi-skill technicians in maintenance shops over multiple periods. The objective of scheduling model is to minimize the total delay time, idle time, and overtime in all maintenance shops, as well as maximizing the number of scheduled repairs and satisfaction levels on shops’ utilization. On the other hand, the sequencing model seeks to minimize the total of shops’ overtime, minimize the sum of actual repairs finish times, and maximize satisfaction on repair finish times. A real case study was provided for illustration of the proposed models for which the results revealed that the proposed scheduling and sequencing models efficiently minimized maintenance costs while maximizing the number of failure repairs and shops utilization. Finally, sensitivity analyses were conducted on both models. In conclusion, the proposed models can be applied to maintenance scheduling and sequencing in a wide range of business applications to obtain effective plans of maintenance activities that achieve the desired goals of maintenance department and/or save costly maintenance resources. Finally, this research contributes to theory of maintenance planning by considering varying failure types that require distinct technician’s repair skills.
