Patent ID: 7177827

Claim:
Logic for generating an order plan, the logic being encoded in computer readable media and when executed by a computer operable to: access data describing a plurality of priority levels, each priority level comprising at least one item request; access data describing a supply chain network comprising a plurality of network components, each network component operable to supply one or more items to satisfy an item request; access data about infeasible periods of time associated with one or more respective network components, wherein the data about infeasible periods of time associated with one or more respective network components comprises data about infeasible periods of time associated with one or more respective network components that were determined for higher priority levels; for each priority level: for each item request of a priority level: plan an order for an item request of a current priority level using the data about infeasible periods of time associated with a plurality of network components that are unable to satisfy an item request during respective periods of time; and determine any additional unplannable network components for the current priority level; validate the additional unplannable network components; and record the validated unplannable network components for the current priority level; and provide an order plan comprising the orders planned for the item requests at each priority level.
