Abstract: A method (200) for inventory planning for a supply chain distributing a constrained supply of stock includes determining (204) an anticipated inventory replenishment need for each of a plurality of first nodes at a lowest level tier of the supply chain for which inventory data is available. The method further includes determining (212, 216) an allocation of stock in the supply chain so as to fulfill (220) the anticipated inventory replenishment needs of the plurality of first nodes before allocating any remaining stock to fulfill anticipated inventory needs of nodes at higher level tiers of the supply chain. The method additionally includes distributing stock in the supply chain based on the allocation of stock.

Abstract: A method and apparatus provide material requirements planning adjustments. A system generated future material requirements planning value can be generated for at least one material for a product. An estimated future lifecycle requirements planning value can be determined for the at least one material. The system generated material requirements planning value can be compared with the estimated future lifecycle requirements planning value. The system generated future material requirements planning value can be adjusted based on comparing the system generated material requirements planning value with the estimated future lifecycle requirements planning value. A material requirements planning signal representing the adjusted system generated future material requirements planning value can be output.
