Range Analysis
Range analysis is sensitivity analysis for specific change vectors.
As with the sensitivity analysis case, care must be used
in interpreting the results of range analysis
when the problem has integers or the preprocessing option is enabled.
The effects on the optimal solution
of changes in each right-hand-side value
can be studied using the RANGERHS option
in the PROC LP or RESET statement.
This option results in sensitivity analysis for
the m right-hand-side
change vectors specified by the columns of the
m×m identity matrix.
The effects on the optimal solution
of changes in each price coefficient
can be studied using the RANGEPRICE option
in the PROC LP or RESET statement.
This option results in sensitivity analysis for
the n price change vectors specified by the rows of the
n×n identity matrix.
