The second model aims to schedule the confirmed requests by the first assigning model. We are interested in the optimal repartition of the confirmed requests, while minimizing the flights delays. These models are used to optimize the air-traffic management of the Diass airport. Therefore, we have developed and implemented two algorithms for the resolution of these two models. The ressults of experimentations in Cplex show that our algorithms are efficient comparing to those obtained by the reference works existing in this field. The data used are those of the International Blaise Diagne Airport (AIBD).]]>

Before solving Navier-Stokes equations we introduce a new technique for writing periodic scalar functions or vector fields as the sum of cosine and sine series with proper coefficients. Fourier series representation is background for our new technique.

Periodic nature of initial velocity for Navier-Stokes problem helps us write the vector field in the form of cosine and sine series sum which simplify the problem.
