Şebeke kaynaklı müşteri şikayetleri için akıllı teşhis ve çözüm sistemleri
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. ...
A literature review on inventory management in humanitarian supply chains
In this paper, we present a review and analysis of studies that focus on humanitarian inventory planning and management. Specifically, we focus on papers which develop policies and models to determine how much to stock, ...
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 ...
Intelligent classification-based methods in customer profitability modeling
(Springer International Publishing, 2015)
The expected profits from customers are important informations for the companies in giving acquisition/retention decisions and developing different strategies for different customer segments. Most of these decisions can ...
The effect of multiple operating room scheduling on the sterilization schedule of reusable medical devices
We study scheduling problems of operating rooms (ORs) and sterilization of reusable medical devices (RMDs) where RMDs are the tools that have to be sterilized in order to be reused in the other surgeries. During their ...
Solving the steiner tree problem with revenues, budget and hop constraints to optimality
We investigate the Steiner tree problem with revenues, budget and hop constraints (STPRBH) on graph, which is a generalization of the well-known Steiner tree problem. Given a root node, edge costs, nodes revenues, as well ...
Economic lot sizing problem with inventory dependent demand
(Springer Nature, 2020-11)
We consider an economic lot sizing problem where the demand in a period is a piecewise linear and concave function of the amount of the available inventory after production in that period. We show that the problem isNPhard ...
Preface: 13th cologne-twente workshop on graphs and combinatorial optimization (CTW 2015)
A robust optimization approach for production planning under exogenous planned lead times
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 ...
A robust optimization approach for humanitarian needs assessment planning under travel time uncertainty
We focus on rapid needs assessment operations conducted immediately after a disaster to identify the urgent needs of the affected community groups, and address the problem of selecting the sites to be visited by the ...
