Concerning the constraint set
I am having problem with the last term of the constraint (?):
@constraint(model, [m in 1:machines, j in 1:jobs], PT[m,j] == SET[m] * Z[m,j] + VT[m]*(sum(v[i] * X[m,j,i] for i in 1:parts) + HT[m] * (?)))
How can I determine
Note: X and Z are a binary decision variables; PT is a continuous decision variable; SET, VT, and HT are parameters (input data).
