PPDS Optimizer

Hi

We have issue in PPDS optimizer with respect to sequencing of Semi Finished and Finsihed Product planned orders. After PPDS optimizer run we see Semi Finished are scheduled after Finsihed products.

We use PPDS optimizer.First we convert SNP planned order to PPDS planned order.After that run PPDS optimizer.

Finsihed product availability is on 01/04/2016 whereas Semi Finished is available on 20/04/2016.

We are using dynamic pegging relationship. Kept 30days of Maximum Earliness of a Receipt and Maximum Lateness of a Receipt at Semi Finished Level. For Finsihed Product level 400 days.Also In FG level there is 10 days as GR time to capture the Quality Inspection activities.

Expectation is schdule first the Semi finished products and then finished product.

Is there way to restrict this kind of sequencing. Suppose if my Semi Finished is getting delayed it should postpone Finsihed Product as well using PPDS Optimizer.In optimizer profile I have not activiated the Ignore upstream orders and Do not consider subsequent orders.

We dont want to use fix pegging.Is there way to by using dynamic pegging reletionship.

Please let us know your views.

    Hi all,

    Thank you for your valubale input. The issue is still valid. Bottom up heuristics are not an option since they are not fully finite. I'm trying different settings with worse or better results.

    However I'd like to find your opinion on note 532979. There is a statement:


    "The Optimizer does not work with stock.In particular, this means that it cannot use the stock curve to recognize shortages.It can only recognize violations of pegging relationships and display them as delays.It is therefore important to ensure that pegging is as complete as possible before optimization."


    How should I underatand this? Does PPDS optimizer consider stocks and therefore tries to minimize delays taking the stock into account or not at all?
