How can I specify the first row of the table, and allow the rest to be solved?

GAMS
1

I want to maximize over multiple time periods, with a given starting quantity. What I would like to do is specify

Parameter
A(J)
/A1 100
A2 100
A3 100/;

then have a variable Alpha(I,K), such that for K=1, Alpha=A(J), and for every K>1, Alpha(J,K+1)=B(J,K), where B is a decision variable.

Thank you!

Hi Kendra



You could use something like:



Yourequation(j,k).

Alpha(j, k) =E= A(i)(ord(j) = 1) + B(j,k)(ord(j) > 1);



Cheers
