Scenarios for Fleet Assignment: A Case Study at Lion Air

Fleet Assignment Optimization and Fleet Use Evaluation on Crew Pairing Without Sit Time

“…The computational process only took 2 seconds to provide a solution of a minimum total cost of $ 188,463.1. Based on the analysis, of the three fleet types owned by the airline, only two were used to Blegur et al (2014) also analyzed fleet assignments where the optimization indicated that all fleet types (B733, B734, B738, B739, and B7444) were used, and one aircraft type (B739) was not used because out of a total of 631 domestic and international flights in one day, only 95 fleets were needed (out of a total of 96 fleets). Should this research include all domestic and international flights, it would be possible that all fleet types (even all aircrafts for each type) owned by the airline are also used to serve all flights that are up to 600 flights per day (airline's site, 2022).…”

“…Cases related to costs can be studied from a research conducted in Turkey (Ozdemir et al, 2012) that aimed to minimize the total cost while determining the number of aircrafts staying overnight at hangar. Another study, which is similar but conducted in Indonesia in a different year and objects (Blegur et al, 2014), suggested three scenarios for fleet assignment with their respective objectives, i.e. minimizing operational costs, minimizing the number of aircrafts to meet demand, and minimizing operational costs and fleet size simultaneously.…”
