Optmizer constraint error - non linear constraint

sourabhvk

Hi,

 

I am working on a production planning optimization problem. I am building a minimum order quantity functionality using a binary variable. But I am getting error message 'The constraint has a formula that is not liner'. when I am removing this binary variable the error is resolved. Isn't it possible to use the binary variables in the optmizer?

 

Thanks,

Sourabh
