CAPACITY variable ;
CAPAC variable ;
UPPERBD variable ;
The CAPACITY statement identifies the SAS variable in the ARCDATA= data set that contains the maximum feasible flow or capacity of the network arcs. If an observation contains nonarc variable information, the CAPACITY list variable is the upper value bound for the nonarc variable named in the NAME list variable in that observation.
When solving an LP, the CAPACITY statement identifies the SAS variable in the ARCDATA= data set that contains the maximum feasible value of the LP variables.
The CAPACITY list variable must have numeric values. It is not necessary to have a CAPACITY statement if the name of the SAS
variable is _CAPAC_, _UPPER_, _UPPERBD, or _HI_.
