The effect of multiple operating room scheduling on the sterilization schedule of reusable medical devices
(Elsevier, 2020-09)
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
(IEEE, 2013)
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 ...

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 ...
A robust optimization approach for humanitarian needs assessment planning under travel time uncertainty
(Elsevier, 2020-04-01)
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 ...
Allocating cost of service to customers in inventory routing
(Informs, 2013)
Vendor-managed inventory VMI replenishment is a collaboration between a supplier and its customers, where the supplier is responsible for managing the customers' inventory levels. In the VMI setting we consider, the supplier ...
Polarity classification of twitter messages using audio processing
(Elsevier, 2020-11)
Polarity classification is one of the most fundamental problems in sentiment analysis. In this paper, we propose a novel method, Sound Cosine Similaritye Matching, for polarity classification of Twitter messages which ...
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 ...
An effective formulation of the multi-criteria test suite minimization problem
(Elsevier, 2020-10)
Test suite minimization problem has been mainly addressed by employing heuristic techniques or integer linear programming focusing on a specific criterion or bi-criteria. These approaches fall short to compute optimal ...
