For many practical applications it is important to determine not only a numerical approximation of one but a representation of the whole set of globally optimal solutions of a non-convex optimization problem. Then one element of this representation may be chosen based on additional information...

This paper discusses necessary optimality conditions for multi-objective optimization problems with application to the Second Theorem of Welfare Economics. We use the extremal principle, since we consider non-convex sets non-smooth functions. Particularly, we develop a slight generalization of...

A capacitated two-stage time minimization transportation problem is considered in this paper, in which the total availability of a homogeneous product at various sources is more than the total requirement of the same at destinations. Unlike the conventional imbalanced time minimization...
