Tradeoff directions and dominance sets

摘要

In this paper, we provide a short survey of tradeoff concepts and present a scalari-zation the parameters of which allow one to calculate the tradeoffs as efficient points of the contingent cone in its optimal solution, if certain differentiability assumptions are fulfilled at this efficient point. The scalarization is based on the idea to look for vectors being efficient w.r.t. some widened dominance cone.
