Hello everyone,

I want to add a command in which if variable " f(i,j) " is lower than an amount, then it is omitted from the next equation .something like an “if and then command” .for example :

if f(i,j)=L=5, then put f(i,j)=e=0 .

(lets say f(‘1’,‘1’)=2 then we should have f(‘1’,‘1’)=e=0 for the next calculations.) .

thank you very much

Dear Dehghani

Do u mean u are planning to use an iterative approach (algorithm)? Or in contrast, you need to consider that in a one (single) consolidated model?

For the former, u need to define a parameter (or a dynamic set) that updates the set of equations in each iteration (after each solve statement simply) .

For the latter, you need to use available modeling techniques. [most likely integer programming ]

## I hope that can help as a small initiator .

Regards
