  • Team planning under an electricity failure for a GSM operator 

    Üney-Yüksektepe, Fadime; Çakır, Kübra; Yılmaz, Nur; Bayrak, Meltem (2019)
    Base stations are very important for all GSM operators. Efficient base stations prevent income loss while bringing prestige to the company. This study deals with the problem of transportation planning of portable generators ...
  • A novel fuzzy TOPSIS method using emerging interval-valued spherical fuzzy sets 

    Kutlu Gündoğdu, Fatma; Kahraman, Cengiz (2019-06-03)
    All the extensions of ordinary fuzzy sets with three-dimensional membership functions such as intuitionistic fuzzy sets, second type intuitionistic fuzzy sets (or Pythagorean fuzzy sets) and neutrosophic sets aim at defining ...
  • The r-interdiction selective multi-depot vehicle routing problem 

    Sadati, Mir Ehsan Hesam; Aksen, Deniz; Aras, Necati (WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ USA, 2020)
    The protection of critical facilities has been attracting increasing attention in the past two decades. Critical facilities involve physical assets such as bridges, railways, power plants, hospitals, and transportation ...

    AKBURAK, DILEK; Şenvar, Özlem; Yel, Necla (2019-11)
    In the digitalization era, enterprises are required to proactive customer relationships via analytical techniques to execute customer treatment strategies based on predictive analytics drawing on a wealth of data about ...
  • Wind farm layout optimization to maximize total power production 

    ÜLKÜ, ILAYDA; Alabaş Uslu, Çiğdem (2018-05)
    With the rapid increase in energy demand, renewable energy has been considered as an alternative energy resource around the world. A new nonlinear mathematical model is developed in the presented study and a comparison is ...
  • Intellegent Sytems for Disaster Management : Anmanned Aerial Vehicles 

    DÜNDAR, Uğurcan (2019-07)
    This paper formulates the UAVs' surveillance problem as a location-routing problem, where limited energy capacities of UAVs are modeled explicitly as constraints that account for their different flight statuses. The ...
  • An Integrated Pythagorean Fuzzy AHP & TOPSIS Method for the Selection of the Most Appropriate Clean Energy Technology
