Hi, I need to sum the variable Dmet(b,t) over b, which varies from 1 to b-1.
The variable Dmet is the demand met at a certain day t with a certain batch b so Dmet is defined by two indices.
I tried to formulate it but it is not working, can anyone help me out? Thanks!!
This is part of the code:
Dmet(3,t)= D - symsum(Dmet(b,t),b,1,b-1)
Do I have to use a syms diffferent than b?
