With the growth of ocean transport and with increasing vessel sizes, managing congestion at the landside of container terminals has become a major challenge. A terminal landside handles containers that arrive or depart via train or truck. Large terminals have to handle thousands of trucks and...

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...

Many intra-logistics systems, such as automated container terminals, distribution warehouses, and crossdocks observe parallel process flows, which involve simultaneous (parallel) operations of multiple independent resources while processing a job. Due to the unknown service time of the job,...

Design of container terminal operations is complex because multiple factors affect the operational performance. These factors include: topological constraints, a large number of design parameters and settings, and stochastic interactions that interplay among the quayside, vehicle transport, and...

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....

In the future, vehicle sharing systems will be unmanned, autonomous, and electric. In this paper, we design operating policies for sharing platforms with such vehicles. These platforms must decide which vehicle with which battery level should pick up which type of customer and which vehicle...

Platforms sharing autonomous electric vehicles have to decide which vehicle should pick up which type of customer and when vehicles should be recharged, based on remaining battery level and proximity to the charging station. We model and analyze this problem. To guarantee maximum service and...

The facility layout problem (FLP) is the problem of determining non-overlapping positions of departments on the shop floor to minimize material handling costs. Traditional methods for solving FLPs consider pairwise (from-to) flows to optimize layouts. This paper shows that these traditional...

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...
