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 ...
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 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 ...
Queuing models to analyze dwell-point and cross-aisle location in autonomous vehicle-based warehouse systems
(European Journal of Operational Research, 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 ...
Blocking effects in warehouse systems with autonomous vehicles
(IEEE Transactions on Automation Science & Engineering, 2014)
Autonomous vehicle-based storage and retrieval system (AVS/RS) offers considerable flexibility with respect to throughput capacity in the transfer of unit loads in high density storage areas. AVS/RS relies on autonomous ...
State of the practice: a review of the application of OR/MS in freight transportation
(INFORMS, 2014)
Freight transportation is an important part of the global supply chain. As distances shipped grow and supply chains become more complex and fragile, operations research (OR) can play an important role in improving the ...
Analyzing rental vehicle threshold policies that consider expected waiting times for two customer classes
(Elsevier, 2015)
Vehicle rental providers, which operate in an uncertain environment, offer differentiated services to priority and non-priority customers. In this research, we study one such service differentiation strategy, a vehicle ...
