Maintenance Scheduling of Educational Transport Buses: A Case Study
Scheduling maintenance activities play an important role in the bus transportation system. Nowadays there is the use of the bus for transportation purpose has increased in the decade. In this paper, a case of Sinhgad Institute, Korti campus which is having more than 2000 student uses bus facilities, for coming from nearby 250 villages, 8 Talukas. There are about 32 buses used for transportation. It is one of the important facility provided by the institute. The reliability, availability, and maintainability(RAM) of buses is important for costumers satisfaction & healthy education. It can be achieved by better scheduling of maintenance of buses. It is challenging to schedule the preventive maintenance of 32 buses because of the time limit, labor cost, and management policies. In this paper, for scheduling of buses five types of inspections considered, and constraints as follows, three bays, time to failure (TTF), Time to repair (TTR) and time slot of maintenance. Maintenance data available from past 2–3 years has been considered & TTF and TTR calculated by using the statistical tool. In literature LPP, LIP and branch and bounds methods have been considered for solving more complex problems, but for this problem, Gantt chart is appropriate for scheduling the maintenance of buses. Here 25 buses were scheduled average 6 buses per day for 4 h for 1 week (5 days). This method produces the very close optimal solution for maximum utilization of maintenance facilities.
