Rationalization of model development Illustration : Modeling of organization contribution on support performances

Abstract: This report is resuming the internship I did during Q2 and Q3 2019 at Dassault Aviation on the subject of standardizing the modeling process. In particular, this process needed rationalization. This report is also containing a presentation of my understanding of engineers’ job and engineering work within this particular industry: Dassault Aviation being one of the top main French aircraft constructors, both with business jets and military aircrafts. This work is based on a real case that will roughly be described here too: during the internship, a model aiming at representing the impact of an organization on support performances of an aircraft has been developed. By changing parameters values to evaluate the impact of an organization for different configurations, it has been computed that this impact was negligible for short (<1h) and long (>4h) turn-around duration while being maximum for a turn-around cycle lasting between two to three hours. When developing this model, I could myself experiment different technics aiming at optimizing the development of models: incremental design, organizing specific models through a generic data structure, doing a sensitivity analysis on parameters of a model to allocate resources for an efficient development. Even though this work was made for the support of military aircrafts, it can be extended to a civilian environment, or for drones.
