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 ...
Optimal stack layout in a sea container terminal with automated lifting vehicles
(Taylor and Francis Ltd., 2017)
Container terminal performance is largely determined by its design decisions, which include the number and type of quay cranes, stack cranes, transport vehicles, vehicle travel path and stack layout. We investigate the ...
Cost-effective pallet management strategies
(Elsevier Ltd, 2016)
The existing industry strategies for managing pallets, (single-use expendable pallets, buy/sell programs, and leased pallet pooling programs), are analyzed and compared using push and pull inventory control policies. A ...
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 ...
Estimating performance in a robotic mobile fulfillment system
(Elsevier B.V., 2017)
This paper models Robotic Mobile Fulfillment Systems and analyzes their performance. A Robotic Mobile Fulfillment System is an automated, parts-to-picker storage system where robots bring pods with products to a workstation. ...
Fleet sizing for transporters with seasonal demands
(International Journal of Automation and Logistics, 2013, 2013)
We develop a quick and approximate way to address the fleet sizing problem for transporters with non-stationary demands and uncertain trip times. Non-stationary demands are modelled using Markov-modulated Poisson process ...
Modeling emergency evacuation with time and resource constraints: a case study from Gujarat
(Elsevier Ltd, 2015)
This study develops an off-site emergency response plan for a nuclear power plant in Gujarat, India subject to time constraints with resource limitations and risk of radiation exposure to victims. We formulate an optimization ...
A constrained nash bargaining approach to the stock rationing problem in multi-echelon supply chains
(International Journal of Advanced Manufacturing Technology, 2014)
In order to survive in the global volatile market place, supply chain analysts are brainstorming to arrive at robust inventory control policies that prevents inventory worth of millions of dollars to get tied up in the ...
