Load dependent lead time modelling: a robust optimization approach
(IEEE, 2018-01-04)
Although production planning models using nonlinear CFs have shown promising results for semiconductor wafer fabrication facilities, the lack of an effective methodology for estimating the CFs is a significant obstacle to ...
Solving the integrated shipment routing problem of a less-than-truckload carrier
(Elsevier, 2017)
We study a less-than-truckload (LTL) transportation network and investigate the potential benefits of implementing an integrated solution approach for shipment routing throughout this network. In LTL transportation, shipments ...
A branch‐and‐cut approach for the least cost influence problem on social networks
(Wiley, 2020-07)
This paper studies a problem in the online targeted marketing setting called the least cost influence problem (LCIP) that is known to be NP-hard. The goal is to find the minimum total amount of inducements (individuals to ...
Modeling influenza pandemic and planning food distribution
(Informs, 2014)
Based on the recent incidents of H5N1, H1N1, and influenza pandemics in history (1918, 1957, and 1968) experts believe that a future influenza pandemic is inevitable and likely imminent. Although the severity of influenza ...
Supplier selection for framework agreements in humanitarian relief
(Wiley, 2014-06)
In this study, we consider the supplier selection problem of a relief organization that wants to establish framework agreements (FAs) with a number of suppliers to ensure quick and cost-effective procurement of relief ...
Benchmarking nonlinear optimization software in technical computing environments
(Springer Science+Business Media, 2013-04)
Our strategic objective is to develop a broadly categorized, expandable collection of test problems, to support the benchmarking of nonlinear optimization software packages in integrated technical computing environments ...
Optimization of ATM cash replenishment with group-demand forecasts
(Elsevier, 2015-05-01)
In ATM cash replenishment banks want to use less resources (e.g., cash kept in ATMs, trucks for loading cash) for meeting fluctuated customer demands. Traditionally, forecasting procedures such as exponentially weighted ...
VRP12 (vehicle routing problem with distances one and two) with side constraints
(Elsevier, 2013-08)
The problem undertaken in this study is inspired from a real life application. Consider a vehicle routing problem where the distances between the customer locations are either one or two. We name this problem as VRP12 in ...
Migrating birds optimization: a new metaheuristic approach and its performance on quadratic assignment problem
(Elsevier, 2012-12-25)
We propose a new nature inspired metaheuristic approach based on the V flight formation of the migrating birds which is proven to be an effective formation in energy saving. Its performance is tested on quadratic assignment ...
Dynamic facility location with supplier selection under quantity discount
(Elsevier, 2019-08)
Retailers have to consider several factors when making facility location decisions including suppliers' and customers' locations, customer demand and price offered by suppliers. In this study, we analyze the multi-period ...
