Equity within Air Transportation Management – an Analysis of Inequity Index for Multi-Stakeholders Optimisation

Current equity definition hampers innovation within the Air Traffic Management (ATM). Even if different definitions are currently well established, summer 2018 and 2019 highlighted the urgent need for flexibility and efficiency that current equity definitions cannot cover anymore. Moreover, in any group decision, targeting the best performances for the group can be at the expenses of some stakeholders. Therefore, new equity perspectives must be proposed. In our paper, we propose a new paradigm, and explore the first steps. Equity has a multi-criteria-based definition, and should be guaranteed over time instead of ensuring it in every situation. We first introduce the context of our research and point out, thanks to a literature review, three inequity indexes successfully used in other fields. We analyze their sensitiveness and pertinence according to our problem. We discuss then the results and the following research paths.
