Papageorgiou, Dimitri J.; Nemhauser, George L.; Sokol, Joel - In: European Journal of Operational Research 235 (2014) 2, pp. 350-366

This paper presents a detailed description of a particular class of deterministic single product Maritime Inventory Routing Problems (MIRPs), which we call deep-sea MIRPs with inventory tracking at every port. This class involves vessel travel times between ports that are significantly longer...
