Throughput matching algorithm and stochastic models for analysis of open and closed manufacturing systems
(SSRN, 2016-02)
Order release policies such as card-controlled CONWIP policy aim at improving system responsiveness and minimizing system-wide inventory levels. It is not clear if order release policies (without card control) can be equally ...
Stochastic modelling of unloading and loading operations at a container terminal using automated lifting vehicles
(SSRN, 2015-04)
With growing worldwide trade, container terminals have grown in number and size. Many new terminals are now automated to increase operational efficiency. The key focus is on improving seaside processes, where a distinction ...
Inventory allocation in robotic mobile fulfillment systems
(Taylor and Francis, 2020)
A Robotic Mobile Fulfillment System is a recently developed automated, parts-to-picker material handling system. Robots can move storage shelves, also known as inventory pods, between the storage area and the workstations ...
Location identification for rapid evacuation from a disaster site: a case study from KAPS
(Indian Institute of Management, Ahmedabad, 2014)
Robust plans need to be developed for rapidly evacuating victims from a nuclear disaster site. Although nuclear plants are constructed with multiple redundant safety features, the chances of a leak can never be zero. In ...
Modeling and design of container terminal operations
(IIM Ahmedabad, 2014-06)
Design of container terminal operations is complex because multiple factors affect the operational performance. These factors include: topological constraints, a large number of design parameters and settings, and stochastic ...
Planning the activities of doctors in a teaching hospital
(2013-11-26)
Doctors in a teaching hospital perform a variety of teaching, research, seminar, and
in-patient care activities in addition to managing outpatient volumes. In this paper,
we study the weekly activities of a doctor in a ...
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 ...
Worth the wait? How restaurant waiting time influences customer behavior and revenue
(ScienceDirect, 2018)
In many service industries, customers have to wait for service. When customers have a choice, this waiting may influence their service experience, sojourn time, and ultimately spending, reneging, and return behavior. Not ...
Performance analysis of batching decisions in waveless order release environments for e-commerce stock-to-picker order fulfillment
(International Transactions in Operational Research, 2020-12-14)
Warehouse automation is increasingly adopted to manage throughput fluctuations in e-commerce order fulfillment. This work develops queuing network models and solution methodologies for performance analysis of a stock-to-picker ...
Stochastic modeling of parallel process flows in intra-logistics systems: applications in container terminals and compact storage systems
(European Journal of Operational Research, 2020-08-08)
Many intra-logistics systems, such as automated container terminals, distribution warehouses, and cross-docks, observe parallel process flows, which involve simultaneous (parallel) operations of independent resources while ...
