OPTIMALITY AND DUALITY FOR MULTIOBJECTIVE FRACTIONAL PROBLEMS WITH r-INVEXITY
Jin-Chirng Lee, Shun-Chin Ho · Taiwanese Journal of Mathematics · 2008
We establish necessary and sufficient conditions for efficiency of multiobjective fractional programming problems involving r-invex functions. Using the optimality conditions, we investigate the parametric type dual, Wolfe type dual and Mond-Weir type dual for multiobjective fractional programming problems concerning r-invexity. Some duality theorems are also proved for such problem in the framework of r-invexity.
