Aircraft acquisition is a major investment that can be defined as a strategic activity as it effects the long-term plans of an airline. The selection of an aircraft requires a detailed assessment process since it involves various criteria and alternatives. Thus, aircraft selection can be identified as a multi-criteria decision making (MCDM) problem, which is investigated in this study using a combination of three different MCDM methods, namely Analytic Hierarchy Process (AHP), Decision Making Trial and Evaluation Laboratory (DEMATEL) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). This study uses a comprehensive set of criteria that is associated with aircraft selection, and utilizes AHP and DEMATEL methods to obtain two sets of criteria weights based on expert judgments, which are then combined with TOPSIS method to determine the best wide-body passenger aircraft for airlines. Moreover, the interactions between aircraft selection criteria are investigated and presented with impact relation maps through the use of DEMATEL method. The use of AHP-TOPSIS and DEMATEL-TOPSIS approaches enable to examine the effects of the assumption of criteria independency in the aircraft selection context. The results of the study show that the ranking of alternatives change across the approaches, which is attributed to the effect of criteria independency assumption in AHP method when determining criteria weights.

Static and dynamic aeroelastic analysis of a very light Aircraft Demirer, Halime Gül; Kayran, Altan; Department of Aerospace Engineering (2021-9-10) Aircraft design processes need to ensure that the aircraft is aeroelastically stable within its operational envelope. This thesis presents an overview of the static aeroelastic, flutter and gust response analysis of a very light aircraft. MSC.FlightLoads and MSC.Nastran are used for aeroelastic modeling and analysis. The methods to be used in the aeroelastic analysis of the VLA are tested on the AGARD 445.6 wing, and the results are in good agreement with the literature. Aeroelastic model corrections such a...
Integrated aircraft-path assignment and robust schedule design with cruise speed control Safak, Ozge; Gürel, Sinan; Akturk, M. Selim (2017-08-01) Assignment of aircraft types, each having different seat capacity, operational expenses and availabilities, critically affects airlines' overall cost. In this paper, we assign fleet types to paths by considering not only flight timing and passenger demand, as commonly done in the literature, but also operational expenses, such as fuel burn and carbon emission costs associated with adjusting the cruise speed to ensure the passenger connections. In response to flight time uncertainty due to the airport conges...
Task assignment and scheduling in UAV mission planning with multiple constraints Semiz, Fatih; Polat, Faruk; Department of Computer Engineering (2015) In the recent years, unmanned aerial vehicles (UAVs) have started to be utilized as the first choice for high risk and long duration tasks, because UAVs are cheaper; they are hard to be noticed and they can perform long duration missions. Furthermore, the utilization of UAVs ensures to reduce the risk to the human life. Examples of this kind of missions includes signal collection, surveillance and reconnaissance and combat support missions. It is valuable to develop a fully autonomous UAV fleet to perform t...
Architectural Design Quality Assessment Based On Analytic Hierarchy Process: A Case Study Harputlugil, Timuçin; Gültekin, A.Tanju; Prins, Matthijs; Topçu, Y. İlker (Middle East Technical University, Faculty of Architecture, 2014) Karmaşıklığından dolayı, mimari tasarım kalitesinin değerlendirilmesi zordur. Ölçütlerin belirlenmesi, yöntemin ortaya konması ve kalitenin kimin için, kimler tarafından ve nasıl değerlendirileceği mimarlık alanında süregelen önemli tartışma konularından biridir. Bu amaçla, devam eden tasarım süreçlerine girdi veremeyen, çoğunluğu kullanım süreci değerlendirmesinde kullanılan pek çok değerlendirme aracı geliştirilmiştir. Bu yazı, tasarımın ilk aşamalarından son aşamalarına kadar kullanılabilecek Analitik Hi...
Integrated aircraft and passenger recovery with cruise time controllability Arikan, Ugur; Gürel, Sinan; Akturk, M. Selim (Springer Science and Business Media LLC, 2016-01-01) Disruptions in airline operations can result in infeasibilities in aircraft and passenger schedules. Airlines typically recover aircraft schedules and disruptions in passenger itineraries sequentially. However, passengers are severely affected by disruptions and recovery decisions. In this paper, we present a mathematical formulation for the integrated aircraft and passenger recovery problem that considers aircraft and passenger related costs simultaneously. Using the superimposition of aircraft and passeng...
