Robust plans need to be developed for rapidly evacuating victims from a nuclear disaster site. Although nuclear plants are constructed with multiple redundant safety features, the chances of a leak can never be zero. In the event of a nuclear disaster, there is a need for an efficient evacuation...

Shuttle-based compact systems are new automated multi-deep unit-load storage systems with lifts that promise both low operational cost and large volume flexibility. In this paper, we develop novel queuing network models to estimate the performance of both single-tier and multi-tier shuttle-based...

With growing worldwide trade, container terminals have grown in number and size. Many new terminals are now automated to increase operational efficiency. The key focus is on improving seaside processes, where a distinction can be made between single quay crane operations (all quay cranes are...

Due to a rapid growth in world trade and a huge increase in containerized goods, sea container terminals play a vital role in globe-spanning supply chains. Container terminals should be able to handle large ships, with large call sizes within the shortest time possible, and at competitive rates....

Order release policies such as card-controlled CONWIP policy aim at improving system responsiveness and minimizing system-wide inventory levels. It is not clear if order release policies (without card control) can be equally effective under certain settings of the production system design...

A Robotic Mobile Fulfillment System is a recently developed automated, parts-to-picker material handling system. Robots can move storage shelves, also known as inventory pods, between the storage area and the workstations and can continually reposition them during operations. This paper shows...

Well-designed and timely reminders can mitigate individuals’ limited attention by bringing the desirable activity (and its outcome) to the top of their minds. However, individuals may mentally switch off to such reminders if they are delivered repetitively in a monotonous fashion. Drawing from...
