Soit F une famille de critères conçue pour asseoir un modèle de préférences global sur un ensemble A d'actions potentielles (ou alternatives). On se place ici dans une perspective d'aide à la décision et dans l'hypothèse où des dépendances (encore
appelées interactions) sont susceptibles d'exister entre certains des critères de F. On commence (cf. Sect. 2.1) par préciser ce que signifie
l'affirmation "il existe des dépendances entre certains des critères de F" (Déf. 1). On s'intéresse ensuite...
2000 Mathematics Subject Classification: 90C25, 68W10, 49M37.A general framework of the (parallel variable transformation)
PVT-type algorithm, called the PVT-MYR algorithm, for minimizing a non-smooth convex function is proposed, via the Moreau-Yosida regularization.
As a particular scheme of this framework an ε-scheme is also presented. The
global convergence of this algorithm is given under the assumptions of strong
convexity of the objective function and an ε-descent condition determined
by an...
Using monotone bifunctions, we introduce a recession concept
for general equilibrium problems relying on a variational convergence notion. The interesting purpose is to extend some results of P. L. Lions on
variational problems. In the process we generalize some results by H. Brezis
and H. Attouch relative to the convergence of the resolvents associated with
maximal monotone operators.
A new postprocessing technique suitable for nonuniform triangulations is employed in the sensitivity analysis of some model optimal shape design problems.
The popularity of TCP/IP has resulted in an increase in usage of best-effort networks for real-time communication. Much effort has been spent to ensure quality of service for soft real-time traffic over IP networks. The Internet Engineering Task Force has proposed some architecture components, such as Active Queue Management (AQM). The paper investigates the influence of the weighted moving average on packet waiting time reduction for an AQM mechanism: the RED algorithm. The proposed method for...
