Selection between different PPM's in APO

Hi all,

I have 3-4 PPM's per product,

that differs in production times or components used.

Can someone tell me how can I optimize the selections of PPM.

PP/DS does not interested in optimizing the correct PPM,

rather it solves inside PPM's by modes.

But I want to solve first the correct PPM according to the costs, delays, prod. time etc. An then scheduling comes.

How can I do that, SNP, CTM???
