    A New Network Flow Model for Determining the Assortment of Roll Types in Packaging Industry
    (IEEE, 2010) Tombus, Onder; Ertek, Gurdal; Atay, Ceren; Kokten, Gizem; Tombus, Ayse Cilaci
    This paper reports work motivated by a real world assortment problem in packaging industry. A novel network flow model has been developed to solve the problem of selecting the optimal set of roll types for use in production. The model can incorporate fixed costs that depend on the number of elements in the assortment as well as the selected roll types. While the trade-off between inventory cost and cost of waste is resolved optimally through the model, graphical understanding of the trade-off can bring insights into the decision making process. This graphical analysis has been demonstrated on a computational example.

    Optimizing the electric charge station network of ESARJ
    (ELSEVIER SCIENCE BV, 2014) Gavranovic, Haris; Barut, Alper; Ertek, Gurdal; Yuzbasioglu, Orkun Berk; Pekpostalci, Osman; Tombus, Onder; Shi, Y; Lepskiy, A; Aleskerov, F
    In this study, we adopt the classic capacitated p-median location model for the solution of a network design problem, in the domain of electric charge station network design, for a leading company in Turkey. Our model encompasses the location preferences of the company managers as preference scores incorporated into the objective function. Our model also incorporates the capacity concerns of the managers through constraints on maximum number of districts and maximum population that can be served from a location. The model optimally selects the new station locations and the visualization of model results provides additional insights. (C) 2014 Published by Elsevier B.V.
