Hi Matthias, Thanks, this is very helpful to me. Best regards, Yu

Hi Jonasz， I'm sorry I didn't think carefully about the method you proposed, and I did the calculation again using your method. It worked. Thank you very much! Yu

This is my objective function： My code is as follows： m = gp.Model("MCIkRP1")K = [k.no for k in orders] P = [p.no for p in paths]T = [t for t in range(1, 60)]x = m.addVars(K, P, vtype=GRB.INTEGE...

Sorry, I didn't describe the problem I encountered clearly. I would like to solve the following problem， Cargo k starts shipping at time and arrives at time.  The start time  is known (represents ...

Thanks. I will try to reconstruct the constraint using the method you mentioned.
