Hi,
I have an array of values
"number Quantity{Item}=[0 0 30 40 50 0 60 70]" and want to assign these values to another array Quantity2 and change the index to -2 so it should equal [30 40 50 0 60 70 0 0]. How to achive that with optmodel.
Here's one way:
proc optmodel;
set Item = 0..7;
number Quantity{Item}=[0 0 30 40 50 0 60 70];
number Quantity2{i in Item} = Quantity[mod(i+2,8)];
print Quantity Quantity2;
quit;
SAS Output
[1] | Quantity | Quantity2 |
---|---|---|
0 | 0 | 30 |
1 | 0 | 40 |
2 | 30 | 50 |
3 | 40 | 0 |
4 | 50 | 60 |
5 | 0 | 70 |
6 | 60 | 0 |
7 | 70 | 0 |
Thanks Rob,
what I am trying to achieve is to take the optimized quantity "Quantity", offset it x places, and give this output (Quantity) as an input to Quantity2, where I will run another optimization model on it Quantity2. " I assume I can have both in the same program?"
So Quantity is not actually a number it's a variable and I receive the following error when saying that
Quantity2{i in Item} = Quantity[mod(i+2,8)];
as Quantity is a var and Quantity2 is number
537-782 the value of parameter "Quantity2" depends on a variable
If Quantity is a variable, then it sounds like you want to declare Quantity2 as an implicit variable (by using the IMPVAR statement).
