Scenarios for Fleet Assignment: A Case Study at Lion Air

Abstract

Given the sets of flights and aircrafts of an airline, the fleet assignment problem consists af assigning the most profitable aircraft in every flight. In this paper, the model of fleet assignment is set up using the data from the airline company 1vhich has the largest market in Indonesia, i.e. Lion Air. It's involved the n1mvay constraints in the model to result more realistic scenarios, \vhere rhree scenarios of the flee! assignment have been analyzed The aim of the first scenario is to assign the most appropriate fleet type to flights while minimizing the cost. The second scenario is to see u·hat is the n1inin111n1 number of aircraft required to cover all flights. The aim of the third scenario is to assign the most appropriate fleet type to flights while minimi:ing not only the cost but also the number of aircraft for all flights. Models have been set up under constraints of all airline operations and formulated in term of an integer linear programming. The solution of these problems generates a minimum daily cost of fleet assignment and the minimum number of aircraft for all flights.
