This research is concerned with the study of bulk queueing models. A number of M/G/l queues with bulk-arrival and/or bulk-service are studied via the imbedded Markov chain technique to derive steady-state models. Results from these models are compared with simulation results after the appropriate numerical analysis, needed to implement these solutions, has been considered. Similar queueing models are considered from a time-dependent viewpoint. Because of the difficulties of obtaining time-dependent solutions, the emphasis is placed upon the development of approximations to the queueing results. Finally, to demonstrate the practicability of these models, two real-life problems are considered, namely the Gatwick Rapid Transit systems and the proposed Channel Tunnel freight shuttle operation. It is demonstrated that the former is an under-utilised system, while the latter is likely to operate very close to its capacity conditions.
