Refinery Optimization: How to Run an Oil Refinery

Features Demonstrated

The following features are demonstrated in this example:

problem type: linear programming (generalized network flow with side constraints)
numeric and string index sets
reading sparse two-dimensional data
NOMISS option
sets of tuples
bounds in the VAR statement
.ub variable suffix
using a colon (:) to select members of a set
set operators UNION, DIFF, CROSS, and SETOF
linearizing a ratio constraint
range constraint
INDEX function
implicit slice
using a variable suffix (such as .sol) in the declaration of a numeric parameter
index set in the PRINT statement
