Optimal partitioning of vertical zones in vehicle-based warehouse systems
(International Journal of Production Research, 2014)
New innovations in warehouse automation systems such as autonomous vehicle-based storage and retrieval (AVS/R) system offer greater flexibility and responsiveness in processing unit-load storage and retrieval transactions ...
Improving service system performance using estimates of waiting time probabilities
(International. Journal. of Automation and Logistics, 2014)
Queue length distributions provide insight into the impact of service
system design changes that go beyond simple performance measure averages;
however, such distributions are difficult to estimate when service times are ...
Queuing models to analyze dwell-point and cross-aisle location in autonomous vehicle-based warehouse systems
(Elsevier, 2015)
Technological innovations in warehouse automation systems, such as Autonomous Vehicle based Storage and Retrieval System (AVS/RS), are geared towards achieving greater operational efficiency and flexibility that would be ...
Stochastic models for unit-load operations in warehouse systems with autonomous vehicles
(Springer Science+Business Media, 2015)
This paper presents stochastic models for multi-tier warehouse systems that handle unit load transactions using autonomous vehicle-based technology. In this system, self-powered autonomous vehicles carry out unit-load ...
A non-linear traffic flow-based queuing model to estimate container terminal throughput with AGVs
(Taylor & Francis, 2016)
Efficient handling of containers at a terminal can reduce the overall vessel sojourn times and minimise operational costs. The internal transport of containers in these terminals is performed by vehicles that share a common ...
Determinants of safe and productive truck driving: empirical evidence from long-haul cargo transport
(Elsevier Ltd, 2017)
Using GPS data of 370 long-haul trips in India, survey data of 49 truck drivers, and ERP data, this study examines the role of driver personality characteristics in predicting risky and productive driving. The results show ...
Selection of pallet management strategies based on carbon emissions impact
(Elsevier, 2015)
This work describes the lifecycle of wood pallets as they move through the supply chain and compares the environmental impacts of the three predominant pallet management strategies: single-use expendable, reusable buy/sell, ...
A nested semi-open queuing network model for analyzing dine-in restaurant performance
(Elsevier Ltd, 2016)
Low customer wait times at restaurants can improve both customer walk-ins and satisfaction levels. To manage customer wait times, the operators need a thorough understanding of how restaurant design parameters such as the ...
A novel approach for designing rental vehicle repositioning strategies
(IIE Transactions, 2014)
An important tactical decision for vehicle rental providers is the design of a repositioning strategy to balance vehicle utilization with customer wait times due to vehicle unavailabilities. To address this problem, this ...
A multi-tier linking approach to analyze performance of autonomous vehicle-based storage and retrieval systems
(Elsevier Ltd, 2017-06-23)
To improve operational flexibility, throughput capacity, and responsiveness in order fulfillment operations, several distribution centers are implementing autonomous vehicle-based storage and retrieval system (AVS/RS) in ...
