Integrated blood collection and appointment scheduling
(Institute of Industrial Engineers, 2012)Considering the processing requirements of donated blood, we study an integrated blood collection and appointment scheduling problem. We develop a mixed integer programming model to maximize the amount of donated blood ... -
International roaming traffic optimization with call quality
(SciTePress, 2019)In this study we focus on a Steering International Roaming Traffic (SIRT) problem with single service that concerns a telecommunication’s operators’ agreements with other operators in order to enable subscribers access ... -
IP-based energetic reasoning for the resource constrained project scheduling problem
(Elsevier, 2010-08-01)In this paper, we consider the Resource Constrained Project Scheduling Problem (RCPSP). New feasibility tests for the energetic reasoning are introduced based on new integer programming (IP) formulations. Experimental ... -
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 ... -
A longitudinal model for song popularity prediction
(SciTePress, 2021)Usage of new generation music streaming platforms such as Spotify and Apple Music has increased rapidly in the last years. Automatic prediction of a song's popularity is valuable for these firms which in turn translates ... -
A Markovian approach for time series prediction for quality control
(Elsevier, 2019)In this work we aim to predict quality levels of incoming batches of a selected product type to a white goods manufacturer from a third party supplier. We apply a Markov Model that captures the quality level of the incoming ... -
A math-heuristic approach for two echelon vendor managed inventory routing problem
(IEOM Society, 2021)This paper studies a two-echelon vendor managed inventory routing problem of a honey packager company that delivers packaged products from a single facility to multiple retailers and customers. The objective is creating a ... -
A mathematical model for customer lifetime value based offer management
(Springer, 2018)Customers with prepaid lines possess higher attrition risk compared to postpaid customers, since prepaid customers do not sign long-term obligatory contracts and may churn anytime. For this reason, mobile operators have ... -
Next-day operating room scheduling with time-dependent stochastic surgery durations
(Springer, 2022)Operating rooms (ORs) are the most costly part of hospitals, thus a priority for hospital administrations. In this paper, we consider the next-day OR scheduling problem for multiple operating rooms. We assume that surgeries ... -
A novel and successful credit card fraud detection system Implemented in a Turkish Bank
(IEEE, 2013)We developed a credit card fraud detection solution for a major bank in Turkey. The study was completed in about three years and the developed system has been in use since February 2013. It had a great impact in the rule ... -
Optimizing steering of roaming traffic with a-number billing under a rolling horizon policy
(Springer, 2020)In this study, we focus on single service steering international roaming traffic (SIRT) problem by considering telecommunication operators’ agreements and “a-number billing” while keeping service quality above a certain ... -
Profit-based artificial neural network (ANN) trained by migrating birds optimization: a case study in credit card fraud detection
(World Academy of Science, Engineering and Technology, 2015)A typical classification technique ranks the instances in a data set according to the likelihood of belonging to one (positive) class. A credit card (CC) fraud detection model ranks the transactions in terms of probability ... -
Robust aircraft routing and flight retiming
(Elsevier, 2010-08-01)In this paper, we propose an integrated model for the robust aircraft routing and flight retiming problem. The model optimizes a slack-based robustness measure that explicitly takes heed of passengers in connection and ... -
A robust optimization approach for production planning under exogenous planned lead times
(IEEE, 2019)Many production planning models applied in semiconductor manufacturing represent lead times as fixed exogenous parameters. However, in reality, lead times must be treated as realizations of released lots' cycle times, which ... -
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 ... -
Solving credit card fraud detection problem by the new metaheuristics migrating birds optimization
(Springer Science+Business Media, 2013)Statistical fraud detection problem is a very difficult problem in that there are very few examples of fraud. The great majority of transactions are legitimate. On the other hand, for this binary classification problem the ... -
Stochastic production planning with flexible manufacturing systems and uncertain demand: A column generation-based approach
(Elsevier, 2022)The ongoing pandemic, namely COVID-19, has rendered widespread economic disorder. The deficiencies have delayed production at manufacturers in several industries on the supply side. The effects of disruption were more ... -
Strength of three MIP formulations for the prize collecting steiner tree problem with a quota constraint
(Elsevier, 2010-08-01)This paper investigates the quota version of the Prize Collecting Steiner Tree Problem (PCSTP) on a graph as a generalization of the well-known Steiner tree problem. For this challenging network design problem that arises ... -
Summary of an effective formulation of the multi-criteria test suite minimization problem
(IEEE, 2022)This is an extended abstract of the article: Okan Orsan Ozener and Hasan Sozer, 'An Effective Formulation of the Multi-Criteria Test Suite Minimization Problem', published in the Journal of Systems and Software, Vol. 168, ... -
Şebeke kaynaklı müşteri şikayetleri için akıllı teşhis ve çözüm sistemleri
(IEEE, 2016)In the telecommunication sector, there exists a vast variety of protocol data (Such as ADR, IUCS, GB, IUPS, GN) produced by signaling systems. The data contains various information regarding network quality and performance. ...
