Finite tank planning in APO with PPM possible?

Hi gurus,

I am preparing a PP/DS demo system (optimizer) for a beverage company. The idea is to model as much constraints as possible from their production system, and most of them seem to be related to finite tank planning:

- only N flavours possible from a total of 10, but M>N lines can be working simultaneously feeded by the container holding this flavour

- limitations on the flow-rate of this container

etc

This company has not implemented PP-PI in ECC (they have repetitive production).

Has anyone tried and succeeded to model finite tank planning in APO with PPMs (or with discrete planning with PDS)??

any help will be much appreciated.
