Continuous-Time Formulation for Oil Products Transportation Scheduling
This paper presents a novel Mixed Integer Linear Programming (MILP) model for the operational planning of an oil transportation system characterized by a straight multiproduct pipeline with dual purpose terminals that could represent facility input or output. It is based on a continuous representation in both time and volume scales and is capable of meeting all operational constraints related to product sequencing, mass balances and pipeline loading/unloading operations. Contrary to previous approaches, the model allows an intermediate node and the previous segment to simultaneously inject material in the pipeline. Computational results and data are reported.
