A simulation framework for studying blocking effects in warehouse systems with autonomous vehicles
(European Journal of Industrial Engineering, 2016-04-02)
Autonomous vehicles-based storage and retrieval systems (AVS/RS)
have been shown to offer greater flexibility to improve cycle time and
throughput capacity in the transfer of unit loads in high-density storage areas ...
Design, modeling, and analysis of vertical robotic storage and retrieval systems
(Transportation Science, 2018)
Autonomous vehicle-based storage and retrieval systems are commonly used in many fulfillment centers (e.g., e-commerce warehouses), because they allow a high- and flexible-throughput capacity. In these systems, roaming ...
Robotized and automated warehouse systems: review and recent developments
(Transportation Science, 2017)
Robotic handling systems are increasingly applied in distribution centers. They require little space, provide flexibility in managing varying demand requirements, and are able to work 24/7. This makes them particularly fit ...
Review of green supply chain processes
(IFAC-PapersOnLine, 2015)
In the last few decades, environmental concerns of manufacturing operations have motivated the organisations to implement green principles in different processes of the supply chain. In this paper, literature in green ...
An analytical modeling framework for determining the optimal table mix in restaurants
(IFAC-PapersOnLine, 2015)
We present a queuing theory based optimization model for determining the optimal table mix in a restaurant. The optimal table mix problem is formulated for an allotment policy in which the largest available group is allotted ...
A cooperative quay crane-based stochastic model to estimate vessel handling time
(Springer, 2017)
Having a good estimate of a vessel’s handling time is essential for planning and scheduling container terminal resources, such as berth positions, quay cranes (QCs) and transport vehicles. However, estimating the expected ...
Solving semi-open queuing networks with time-varying arrivals: an application in container terminal landside operations
(Elsevier, 2018-06-16)
Semi-open queuing networks (SOQNs) are widely applied to measure the performance of manufacturing, logistics, communications, restaurant, and health care systems. Many of these systems observe variability in the customer ...
Sea container terminals: new technologies and OR models
(Palgrave Macmillan, 2015)
Owing to a rapid growth in world trade and a large increase in the flow of containerized goods, sea container terminals play a vital role in globe-spanning supply chains. Container terminals should be able to handle large ...
An utility-based storage assignment strategy for e-commerce warehouse management
(2019 International Conference on Data Mining Workshops (ICDMW), 2019)
Order picking is one of the most labor intensive and time consuming parts of e-commerce warehouse order management. An effective solution to the item storage assignment problem can significantly improve the efficiency of ...
A stochastic model for interterminal container transportation
(INFORMS, 2017)
We propose a novel semiopen queuing network (SOQN) model for the interterminal transportation (ITT) problem where multiple container terminals use a common
fleet of vehicles (automated lift vehicles, automated guided ...
