Development of a decision optimization model for aircraft workshop capacity

This paper presents an approach to determine the optimal aircraft overhaul capacity in the workshops for an aircraft fleet. The aircraft fleet contains one aircraft type with different models of that type. A mathematical model has been constructed to calculate the lowest cost alternative.The mathematical model uses various types of data to calculate the optimal workshop overhaul capacity like costs, times, numbers of workers, aircrafts used flight time etc. the paper presents one case study carried out representing a future coming need. Parts of the sensitivity analysis are given to show the models behaviour. The objective of this paper is to introduce a model that can be used as a decision helping tool for the decision makers when determine the future needed aircraft overhaul capacity in the workshops. The model can be a part of the emaintenance platform.Godkänd; 2010; 20100823 (ysko);ISBN för värdpublikation: 978-91-7439-120-6
