Technology for Redesigning and Enacting Logistics Management Practices . Sponsored by the US Defense Logistics Agency. Steady State Cyclical Queues.
Most queues are cyclical, in that they exhibit clear daily, weekly or seasonal patterns.
This research first seeks to develop equations that can readily be used to describe the behavior of such queues. Next, we demonstrate how to apply these equations to attain a better understanding of common transportation problems. Planning and Control of Transportation Systems. Today, this lack of ability to re-plan in light of disruptions results in major discrepancies between planned and actual operations.
