### Modeling

Can you tell how can I split the value of decision variable x into x1 and x0? I have wrote a code and ran it. But only x1 is showing values, which is equal to x. I want to split larger demand into two x1 and x0. Addition of both will be x. I have attached my model and constraints. Thank you in advan...

### Re: Equation

Hello Renger, Thank you for your response. This is the code I tried to write for the above constraints 12 to 15. is this correct? x is a production amount for product j and I want to split this amount. ct3(j,t)..x(j,t)=e=x1(j,t)+x0(j,t); ct4(j,t)..x1(j,t)=l=M*z(j,t); ct5(j,t)..x0(j,t)=g=mi*(sum((jj)...

### Equation

In the attachment, 1) constraint 12 has variable x(i,t) but how write that constraint? Do I have to specify three variables x, x1, x0? where x is amount produced.

2) constraint 15, How to write last summation part which is multiplied by M? (k=t+1) to (s-1)

Thank you.
