error PROCEDURE OPTMODEL not found

[Kime]

Hi, I just started using SAS today, I am using the University Edition1, I am trying to maximize a function.

I type 

proc OPTMODEL;
var x1: integer>=0;
var x2: integer>=0;
maximize z=8*x1+20*x2;
con c1: x1+x2<=11;
con c2: 3*x1+2*x2<=30;
con c3: 1*x1+3*x2<=28;
solve;
print x1 x2 z;
quit;

but got the message:

ERROR: Procedure OPTMODEL not found.

bellow there is this message too:

NOTE: The SAS System stopped processing this step because of errors.

NOTE: PROCEDURE OPTMODEL used (Total process time):

real time 0.04 seconds

cpu time 0.03 seconds

66

67 OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK;

what is wrong? is it a syntax error? I was just following advise from a tutorial and can not make this run.

I dont run University edition, but given the error, I dont think you are licensed to run PROC OPTMODEL?

try running the following and see if you have a SAS/OR license 🙂

proc product_status;
run;

PROC OPTMODEL, which is part of SAS/OR software,  is not included in the free SAS University Edition. The first sentence on the SAS UE webpage says "With SAS University Edition, you get SAS Studio, Base SAS, SAS/STAT, SAS/IML, SAS/ACCESS and several time series forecasting procedures from SAS/ETS."
