Optimising M/G/s queues in RTA motor registries

This paper describes a joint study by the Roads and Traffic Authority and the CSIRO, of the behaviour of the queuing systems used in motor registries in New South Wales. The registries operate with multi-queue, multi-service M/G/s queues. The aim of the first stage of the study was to identify the factors that would result in good performance, defined using overall queuing time as the measurement criterion, in these queues. The second stage of the work involved the development of a suitable algorithm that could be used to implement a computer program designed to give an optimal queue arrangement based on the particular customer arrival rates and service times for the transactions carried out in the registry.
