Priority dispatch scheduling in an automobile repair and maintenance workshop

This research work applied a simulation model in determining the optimal number of artisans to employ to carry out routine checks on vehicles on a waiting line. the waiting line under consideration is that of an automobile repair and maintenance workshop in south- western nigeria. the data collection was based on arrival pattern of vehicles and service pattern of artisans in the maintenance workshop. a discrete distribution was assumed for both the inter-arrival and service time patterns. an optimal number of 7 servers serving one queue were obtained as against 4 servers and 1 queue in the system in use. there was also a savings in cost of n2.45 million per month when compared to the system in use. the results of this research work will be significant and important for decision making. © school of engineering,taylor's university.
