Duality in fractional programming involving locally arcwise connected and related functions

Stancu-Minasian, I.M. ; Caballero, R. ; Cerdá Tena, Emilio ; Muñoz, María del Mar | Instituto Complutense de Análisis Económico. Universidad Complutense de Madrid | 2002-07

A nonlinear fractional programming problem is considered, where the functions involved are diferentiable with respect to an arc. Necessary and suficient optimality conditions are obtained in terms of the right diferentials with respect to an arc[...]

Relations among several efficiency concepts in stochastic multiple objective programming

Caballero, Rafael ; Cerdá Tena, Emilio ; Muñoz, María del Mar ; Rey, Lourdes | Facultad de Ciencias Económicas y Empresariales. Instituto Complutense de Análisis Económico (ICAE) | 1998

In this paper, the resolutian of stochastic multiple objective prograrmming problems is studied. The existence of random parameters in the objective functions has yielded to the definition of several efficient solution concepts for such problems[...]
