I fixed your question so it is readable.
But, NO. You don't have TWO variables. You have length(x) variables, which appears to be 24.
It just so happens that the first 12 are treated differently than those from 13-24, in the sense that you have two distinct constraints.
I assume that Demand is some fixed number. But if that is true, then what you have written makes absolutely NO sense at all.
We see this:
LB = [zeros(1,12) zeros(1,12)];
UB = [1 1 1 1 1 1 1 1 1 1 1 1 1200 1000 800 800 900 800 700 500 400 200 400 400]
So all the variables must be positive. The first 12 can be no larger than 1. The second 12 can be in the hundreds, and as large as 1200.
But if Demand is some fixed, known constant (10000 apparently) then the sum of the first 12 variables can NEVER be larger than 12.
x1 + x2 +......x12 = Demand
x13+ x14+......x(end) = Demand
Not only that, but we see that
sum([1200 1000 800 800 900 800 700 500 400 200 400 400])
ans =
8100
So the sum of your variables 13-24, even if all are at their maximum can NEVER approach 10000.
So what you have written makes no sense at all.
