Hi experts,
I’m working in a case where we use sequence dependent setup activities (using the setup matrix) in PPDS and I have a scenario where we optimize each week detailed schedule. What I need is to restart the setup sequence at the beginning of the week because the resources are cleaned every weekend. During that cleaning the resource is prepared for the next week’s production so the first order of the next week shouldn’t have a setup time. ¿How can I do this?
- I tried using downtimes on weekends, but the optimizer still uses the last order’s characteristics to calculate the setup time of the next week first order.
- If I reduce the planning period in the DS table to the second week, the optimizer stills take into account the sequence of the first week.
- I may use a dummy order at the beginning of each week, but I would like to avoid this because is difficult to maintain.
Thanks,
Jorge
