• Optimization of Multi-token circulation with master UAV method in multi-UAV systems for location information sharing 

  Ülkü, Eyüp Emre; Ülkü, ilayda (2019)

  In order to perform smooth and coordinated flights in multi-UAV systems, UAVs (Unmanned Aerial Vehicle) need to know each other's location information. Multi-token circulation method allows UAVs to learn each other's ...
• Intelligent systems for disaster management: Unmanned aerial vehicles’ surveillance problem with energy consumption constraints 

  Angün, E.; Dündar, U. (2020)

  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 analytical approach for analysing the impact of risks on production planning: Case of Öztiryakiler 

  Telatar, E.; Bekeç, T.; Başaran, A.; Balıkçı, N.; Bilgin, B.; İlbay, E.; Aktin, T. (2020)

  Accurate and applicable production plans are a must for manufacturing companies. Although companies tend to prepare ideal production plans, some exogenous factors can affect their validity. These risks, which occur ...
• Fuzzy C-Means Algorithm with fixed cluster centers for uncapacitated facility location problems: Turkish case study 

  Esnaf, Şakir; Küçükdeniz, Tarık (2014)

  In this study, a new algorithm to solve uncapacitated facility location problems is proposed. The algorithm is a special version of original fuzzy c-means (FCM) algorithm. In FCM algorithm, unlabeled data are clustered and ...
• A novel VIKOR method using spherical fuzzy sets and its application to warehouse site selection 

  Kutlu Gündoğdu, Fatma; Kahraman, Cengiz (2019)

  The extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets (IFS), Pythagorean fuzzy sets (PFS), and neutrosophic sets (NS), whose membership functions are based on three dimensions, aim at collecting experts' ...
• 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 ...
• Anticipation for Customer Analytics 

  AKBURAK, DILEK; Şenvar, Özlem; Yel, Necla (2019-11)
