A Branch-and-Price Approach for a Ship Routing Problem with Multiple Products and Inventory Constraints

Conference paper
Part of the Operations Research Proceedings book series (ORP)

Abstract

In the oil industry, different oil products are blended in a refinery. Afterwards, these products are transported to different harbors by ship. Due to the limited storage capacity at the harbors and the undesirability of a stock-out, inventory levels at the harbors have to be taken into account during the construction of the ship’s routes. In this paper, we give a detailed description of this problem, which we call the ship routing problem with multiple products and inventory constraints. Furthermore, we formulate this problem as a generalized set-covering problem. We propose a branch-and-price algorithm to solve it and we discuss this briefly.
