Hi all

Which is the diference between TOP down heuristic and Bottom up heuristic?.Is it necesary to run both?

Do this heuristics work with finity capacity?

Thanks in advance.

Hi cordero,

1) Bottom-up heuristic:-

This heuristic tries to reschedule the dates/times of stock transfer requirements and dependent requirements for products with continuous requirements and receipts, so that they are covered on time by existing receipts.

This will be used for products with discrete requirements and receipts.

2) Top Down heuristic:-

This heuristic tries to adjust the availability dates/times of receipts for products with discrete requirements and receipts, so that they cover existing requirements on time.

This can be used with finite and infinite capacity requirements.
