For a school assignment we have to use CPLEX to solve a capactitated lot-sizing problem.

There are 5 different products that have to be produced, and there are 3 machines. One of the conditions is that each product follows a different routing through the machines.

prod A: M1 -> M2 -> M3

prod B: M3 -> M1 -> M2

prod C: M2 -> M1

prod D: M2 -> M3

prod E: M3 -> M2 -> M1

Our question: how can we define/model this routing sequence in CPLEX? Other groups are struggling with the same question.

Thank you in advance!

Hello,

if you still are struggling, you can find in the CPO examples some good inspiration, see for example sched_flowshop.cpp.
