“…Thus, the loaded or unloaded quantities as well as the number of visits at ports were variable. Hennig et al (2015) studied the crude oil tanker routing and scheduling problem with split pickup and split delivery. In their problem, the pickup and delivery quantities of each node were known, but no predefined pairings between pickup and delivery nodes were specified.…”

“…Hennig et al (2012) presented another path flow model for an oil tanker routing and scheduling problem with the objective of finding load sizes, ship routes as well as port arrival and departure times that minimize the overall transportation expenses. Hennig et al (2015) investigated an oil tanker routing and scheduling scenario with split pickup and split delivery, and studied the applicability of the path flow-modelling methods (developed in Hennig et al, 2011Hennig et al, , 2012 within a column generation framework. Aizemberg et al (2014) studied a petroleum transportation problem, and presented a column generation-based framework to solve the problem.…”
This paper presents an optimization based mathematical modelling approach for a single source single destination crude oil facility location transshipment problem. We began by formulating a mixed-integer nonlinear programming model and use a rolling horizon heuristic to find an optimal location for a storage facility within a restricted continuous region. We next design a hybrid two-stage algorithm that combines judicious facility locations resulting from the proposed model into a previously developed column generation approach. The results indicate that improved overall operational costs can be achieved by strategically determining cost-effective locations of the transshipment facility.
