Abstract
Presents
a methodology for short-term crude oil unloading, tank inventory management,
and crude distillation unit (CDU) charging schedule using mixed integer linear
programming (MILP) optimization model as an extension to a previous work
reported by Lee et al. (1996).
Authors attempt to improve the previous model by adding an
interval-interval variation constraint to avoid CDU charging rate fluctuation,
a shutdown penalty within the scheduling cycle and a set up penalty for
tank-tank transfer and introducing demand violation permit for a more flexible
model against obtaining infeasible solution.
