A green ocean carrier network design problem: Empirical study on egyptian port of Alexandria

Abstract

Port sustainability has become a main component of the international maritime transport. This sustainability concept should be integrated in the network design problem to reduce negative externalities for both port and sea activities and the average operational costs by using environmental indicators. The ocean carrier network design problem (OCNDP) will be solved using the triple bottom line of the port green approach to minimize operational costs. Therefore, this problem could be described as a sustainable ocean carrier network design problem (SOCNDP) and it will be solved using the software Microcity and a set of nine regional ports taking as a reference the Egyptian Port of Alexandria. The results show that a green sustainable route can be drawn among these nine ports while minimizing total shipping costs and reducing considerably gas emissions of the various ports.
