Inventory allocation in robotic mobile fulfillment systems
(Taylor and Francis, 2020)
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 ...
Performance analysis of batching decisions in waveless order release environments for e-commerce stock-to-picker order fulfillment
(International Transactions in Operational Research, 2020-12-14)
Warehouse automation is increasingly adopted to manage throughput fluctuations in e-commerce order fulfillment. This work develops queuing network models and solution methodologies for performance analysis of a stock-to-picker ...
Stochastic modeling of parallel process flows in intra-logistics systems: applications in container terminals and compact storage systems
(European Journal of Operational Research, 2020-08-08)
Many intra-logistics systems, such as automated container terminals, distribution warehouses, and cross-docks, observe parallel process flows, which involve simultaneous (parallel) operations of independent resources while ...
AGV or Lift-AGV? Performance trade-offs and design insights for container terminals with robotized transport vehicle technology
(IISE Transactions, 2020-08-13)
New container terminals are embracing robotized transport vehicles such as lift-automated guided vehicles (LAGVs) and automated guided vehicles (AGVs) to enhance the terminal throughput capacity. Although LAGVs have a high ...
A new solution approach for multi-stage semi-open queuing networks: an application in shuttle-based compact storage systems
(Computers & Operations Research, 2020-08-20)
Multi-stage semi-open queuing networks (SOQNs) are widely used to analyze the performance of multi-stage manufacturing systems and automated warehousing systems. While there are several methods available for solving ...
Modeling and design of container terminal operations
(Informs, 2020-04-23)
The design of container terminal operations is complex because multiple factors affect operational performance. These factors include numerous choices for handling technology, terminal topology, and design parameters and ...
