Airline operations are disrupted frequently. The most impor-tant factors are unstable weather conditions and unpredictable techni-cal aeronautics problems. In a disrupted situation, an airline operatorneeds to quickly adjust the timetable and the resource schedules sothe importance of re-assignment of facilities to flight is much moreclearer. In this study, we considered the re-assignment of aircraft toflight after the emergence of disorder in the initial planning with regardto crew scheduling constraints. We propose a problem formulation anda heuristic solution algorithm. 3 Aircraft Maintenance Scheduling and Optimizationfor Summer Period: A Case for Turkish AirlinesYavuz Ozdemir, Industrial Engineering, Yildiz TechnicalUniversity, Yildiz Teknik Universitesi Endustri MuhendisligiBolumu Barbaros Bulvari, Yildiz/Besiktas/Istanbul TURKEY,Istanbul, Turkey, Turkey, [email protected], Ahmet Bolat,Merve Karaca Decreased ticket prices in airline transportation make a competitiveairline market, and forces airline companies to make professional de-cisions for their activities. In this study, C type maintenance, whichis one of the important and long lasting maintenance, is assigned forsummer period considering the capacity of hangar with Microsoft Vi-sual Basic. Maximizing the utilization and minimizing the number orrequired aircrafts are considered as our aims. According to dynamicframe of airline operations and daily irregularities, manual editing isallowed in the code that studied in this paper.
