In this paper, we point out some deficiencies in a recent paper (Lee and Kim in J. Nonlinear Convex Anal. 13:599–614, 2012), and we establish strong du-ality and converse duality theorems for two types of nondifferentiable higher-order symmetric duals multiobjective programming involving cones.

Container ports are a major component of international trade and the global supply chain. Hence, the improvement of port efficiency can have a significant impact on the wider maritime economy. This paper deconstructs a representation in the existing literature that neglects the heterogeneity of individual and group-specific terminal operators. In its place,(More)

Recognizing this fact, many governments have consistently prioritized the ports as a central element of infrastructure to promote regional economic growth. This paper treats container terminal operators as the Decision Making Unit, which represents a divergence(More)
