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 ...
Integrated storage-order picking systems: technology, performance models, and design insights
(Elsevier, 2018-11)
In many warehouses shuttle-based technologies have replaced the traditional AS/R system based storage
technologies. The impact these systems have on downstream order picking performance is largely
unknown. To study the ...
A stochastic model for the throughput analysis of passing dual yard cranes
(Elsevier, 2017-11-14)
New container terminal technologies such as passing dual yard cranes per stack promise increase in stacking throughput capacity. However, dual yard cranes can interfere, which reduces the cranes’ throughput capacity. Using ...
Stochastic modeling of unloading and loading operations at a container terminal using automated lifting vehicles
(Elsevier, 2018-05-01)
With the growing worldwide trade, container terminals have grown in number and size. To increase operational efficiency, many new terminals are now automated. The key focus is on improving seaside processes, where a ...
Carbon footprint analysis of pallet remanufacturing
(Journal of Cleaner Production, 2016-07-10)
This research is the first attempt to characterize the carbon equivalent emissions associated with pallet remanufacturing operations for two repositioning scenarios (cross-docking and take-back), and under multiple levels ...
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 ...
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 ...
