This paper presents a short contribution in air transportation, specifically in scheduling aircraft (plane) landings at Léopol Sédar Senghor (LSS) airport of Dakar. The safety of air navigation of LSS is managed by ASECNA: Agency for Air Navigation Safety in Africa and Madagascar. Scheduling aircraft landing is the problem of deciding a landing time on an appropriate runway for each aircraft in a given set of aircraft such that each aircraft lands within a predetermined time window. The separation criteria between the landing of an aircraft, and the landing of all successive aircraft, are respected. Our objective is to minimize the cost of deviation from the target times. We present a mixed-integer 0 -1 formulation for the single runway case. Numerical experiments and comparisons based on real datasets of LSS airport are presented.
The objective of this study is to analyze the contribution of governance (political stability) as well as per capita income and traffic past measured through the number of passengers traveling by air during a period of one year within each country of the zone to the formation of a hub in the WAEMU zone. Governance has been apprehended through Kaufman indicators which summarize the six dimensions of governance. Three control variables have been added in the model to better explain per capita income and reduce bias in the estimation. To achieve this objective, the study proceeded first with a descriptive analysis which revealed the existence of a positive linear correlation between governance indicators and the level of air traffic, and then with a dynamic panel approach. To this end, the Generalized Moment Method (GMM) showed that the overall contribution of governance to economic performance is not significant in the sample, as well as for each dimension of governance taken individually. However, the results differ when dissociating the specific effect of Senegal, where political stability, government effectiveness, regulatory quality and rules and laws each have a positive and significant impact on per capita income.
