Locating emergency vehicles with an approximate queuing model and a meta-heuristic solution approach Akdoğan, Muharrem Altan; Bayındır, Zeynep Pelin; İyigün, Cem (Elsevier BV, 2018-05-01) In this paper, the location of emergency service (ES) vehicles is studied on fully connected networks. Queuing theory is utilized to obtain the performance metrics of the system. An approximate queuing model the (AQM) is proposed. For the AQM, different service rate formulations are constructed. These formulations are tested with a simulation study for different approximation levels. A mathematical model is proposed to minimize the mean response time of ES systems based on AQM. In the model, multiple vehicl...
Locating emergency vehicles with an approximate queueing model and a meta-heuristic solution ap- proach Akdoğan, Muharrem Altan; Bayındır, Zeynep Pelin; İyigün, Cem (2016-07-05) In this study, the problem of optimal location decision of Emergency Service (ES) vehicles such as ambulances, fire trucks and patrols as a server-to-customer service is discussed. Hypercube queueing model (HQM) are employed to achieve performance measures that are sig- nificant to the location decision of ES vehicles. As an extension of this model, Spatial Queueing Model (SQM) is introduced for spatial networks. This study proposes a generalization of SQM for complete networks. Districting of the demand re...
Locating EMS vehicles in general networks with an approximate queueing model and a metaheuristic solution approach Akdoğan, Muharrem Altan; Bayındır, Zeynep Pelin; İyigün, Cem; Department of Industrial Engineering (2015) In this study, problem of optimal location decision of ambulances as an server-to-customer Emergency Medical Service (EMS) vehicle is discussed. Hypercube queueing models (HQM) are employed to achieve performance measures significant to the location decision of EMS vehicles in spatial networks. Geroliminis et al(2009) extends HQM and propose Spatial Queueing Model(SQM). Our study proposes a generalization of SQM to be used in general networks. Quality of approximations inherit to SQM is questioned, and repo...
Locating mobile facilities in railway construction management Guden, Huseyin; Süral, Haldun (2014-06-01) The location problem with mobile facilities is motivated by a real-life railway construction project. In railway construction, (im)mobile concrete batching facilities are located to build viaducts and tunnels on a line over a planning horizon. The problem is to determine the number and types of facilities to be located, to schedule the movement of mobile facilities, and to make concrete production-allocation decisions, so that all requirements are satisfied, facility capacities are not violated, and the tot...
Locating disaster response facilities in Istanbul Gormez, N.; Köksalan, Mustafa Murat; Salman, F. S. (2011-07-01) We study the problem of locating disaster response and relief facilities in the city of Istanbul, where a massively destructive earthquake is expected to occur in the near future. The Metropolitan Municipality of Istanbul decided to establish facilities to preposition relief aid and execute post-disaster response operations. We propose a two-tier distribution system that utilizes existing public facilities locally in addition to the new facilities that will act as regional supply points. We develop mathemat...
