Samenvatting
We present a new model for determining the optimal block-size under block-queuing in a simple, single-channel queue at a drive-through service facility. With block-queuing, a queue is partitioned into an active section and a passive section, where drivers are asked to turn off their engines until the active section clears. Our model prescribes a block-size, i.e., a maximum number of vehicles in the active section, that minimizes the expected amount of fuel consumed in the queue. It can assess the effects of the traffic intensity, the service-time variance, and the proportion of compliant drivers in the passive section on the optimal block-size and on fuel consumption in the queue.
