In this paper, the definitions of Kuhn-Tucker's proper efficient solution and Klinger's proper effivient solution are generalized to the case of cone order and nonsmooth multiobjective optimization , the concepts of generalized KT-proper efficient solution and generalized K-proper efficient solution are presented, some inter-relationships between them and the inter-relationships among them and local efficient solution and Hartley's proper efficient solution are discussed.
