A stochastic optimization model for designing last Mile relief networks
In this study, we introduce a distribution network design problem that determines the locations and capacities of the relief distribution points in the last mile network, while considering demand- and network-related ...
Pricing decisions in a strategic single retailer/dual suppliers setting under order size constraints
(Informa Group, 2016)
In this paper, we study a duopolistic market of suppliers competing for the business of a retailer. The retailer sets the order cycle and quantities from each supplier to minimize its annual costs. Different from other ...
A profit-driven Artificial Neural Network (ANN) with applications to fraud detection and direct marketing
The rapid growth in data capture and computational power has led to an increasing focus on data-driven research. So far, most of the research is focused on predictive modeling using statistical optimization, while profit ...
A chance constraint based multi-item production planning model using simulation optimization
We consider a single stage multi-item production-inventory system under stochastic demand. We had previously proposed a production planning model integrating ideas from forecast evolution and inventory theory to plan work ...
Selective routing for post-disaster needs assessments
(Springer International Publishing, 2016)
In the immediate aftermath of a disaster, relief agencies perform needs assessment operations to investigate the effects of the disaster and understand the needs of the affected communities. Since assessments must be ...
Production planning with price-dependent supply capacity
(Taylor and Francis, 2016)
We consider a production planning problem in which a producer procures an input component for production by offering a price to suppliers. The available supply quantity for the production input depends on the price the ...
Mitigating the impact of drug shortages for a healthcare facility: An inventory management approach
Despite the importance and value of the pharmaceutical market, a significant portion of procurement spending including pharmaceuticals are lost. Coupling poor and reactive management practices with the inevitable national ...

Robust dual response optimization
(Taylor & Francis, 2016)
This article presents a robust optimization reformulation of the dual response problem developed in response surface methodology. The dual response approach fits separate models for the mean and the variance, and analyzes ...
