LINDO input file for Slick Oil problem
Online Course Material
The LINDO input file below is for the Slick Oil example. The variable names are hopefully somewhat readable so that c1ri refers to crude oil from C1 going to refinery R1. Also r1hfm4 refers to heavy fuel oil from refinery R1 going to market M4.
