HYGAR: a hybrid genetic algorithm for software architecture recovery
(ACM, 2022)
Genetic algorithms have been used for clustering modules of a software system in line with the modularity principle. The goal of these algorithms is to recover an architectural view in the form of a modular structural ...
Capacity planning for effective cohorting of hemodialysis patients during the coronavirus pandemic: A case study
(Elsevier, 2023-01-01)
Planning treatments of different types of patients have become challenging in hemodialysis clinics during the COVID-19 pandemic due to increased demands and uncertainties. In this study, we address capacity planning decisions ...
Multi-instance learning by maximizing the area under receiver operating characteristic curve
(Springer, 2023-02)
The purpose of this study is to solve the multi-instance classification problem by maximizing the area under the Receiver Operating Characteristic (ROC) curve obtained for witness instances. We derive a mixed integer linear ...
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 ...
The effect of few historical data on the performance of sample average approximation method for operating room scheduling
(Wiley, 2023-01)
We model the scheduling problem of a single operating room for outpatient surgery, with uncertain case durations and an objective function comprising waiting time, idle time, and overtime costs. This stochastic scheduling ...
Classification of hundreds of classes: A case study in a bank internal control department
(IOS Press, 2023)
The main function of the internal control department of a bank is to inspect the banking operations to see if they are performed in accordance with the regulations and bank policies. To accomplish this, they pick up a ...
Social media analytical CRM: a case study in a bank
(IOS Press, 2023)
The use of the social media (SM) has become more and more widespread during the last two decades, the companies started looking for insights for how they can improve their businesses using the information accumulating ...
Solving a new application of asymmetric TSP by modified migrating birds optimization algorithm
(Springer, 2023-07)
In this study, we first introduce a new application of the asymmetric traveling salesman problem which is about a small restaurant with one cook and a single stove. Once a meal has started cooking on the stove, the cook ...
Humanitarian relief distribution problem: an adjustable robust optimization approach
(Informs, 2023-07)
Management of humanitarian logistics operations is one of the most critical planning problems to be addressed immediately after a disaster. The response phase covers the first 12 hours after the disaster and is prone to ...
Healthcare inventory management in the presence of supply disruptions and a reliable secondary supplier
(Springer, 2023-12)
We study the inventory review policy for a healthcare facility to minimize the impact of inevitable drug shortages. Usually, healthcare facilities do not rely on a single source of supply, and alternative mechanisms are ...
