A dynamic routing system for short sea shipping following ship immobilisation

Abstract

There are many uncertainty factors within a decision-support system for maritime transport that dynamically affect such a system. The scope of this paper is to investigate the impact of such factors on the system operation and terms enabling alternative route scenarios to effectively treat the impact of the respective uncertainty factors. The case that we consider is that of a ship experiencing insurmountable problems (e.g., damage) during operation and being forced to stop; it cannot then serve subsequent ports on its route. We attempt to find alternatives provided by the system to support decisions by presenting an algorithm for the optimal dynamic rearrangement of schedules of other ships to meet the demand after a vessel's immobilisation.

A queuing-based mathematical model for the congested network design problem under demand uncertainty

“…are various applications of network design models. Many scholars have studied the problem of transportation NDP (e.g., Ukkusuri et al, 2007;Wieberneit, 2008;Bianco et al, 2009;Zhu et al, 2014;Miandoabchi et al, 2015;Wang et al, 2015;Tan et al, 2016;Chainas, 2017).…”
