A method and apparatus that maintains a database of the demands over time for all the different refurbished machines is disclosed. The invention also maintains the supply over time of all the different machines that will be returned from expired leases. The invention maintains the relationship for alternate parts which parts can be used in place of another. The invention also maintains an inventory of parts and machines. As machines are returned from expired leases, they come into inventory. From this inventory, some of the machines will, from time to time be scheduled to be refurbished or demanufactured. The balance will remain in inventory. When a machine is demanufactured, all of the parts that are produced will be put in inventory. However, some may be used immediately to satisfy a demand for the part and the balance may be used to satisfy demand for the same part later or be used as an alternate part for some other part. The invention also maintains a bill-of-materials that is a cross reference of all the parts that can be produced from each machine. Related to this are parametric data that is required. These data are yields associated with the refurbishing and demanufacturing process, the offset or time required for these processes, the resources required and the capacity of the resource, etc. The final set of information that is maintained by the invention are the priorities of the different demands. These priorities can be time sensitive, if required. These priorities reflect the economic advantage of satisfying one demand before another. For example, demands for refurbished machines may have a high priority, reflecting the consideration that refurbishing generally requires minimal effort and generates a large revenue and profit. Demands (auction/sales) for certain parts sometimes have a high resale value and they would be given a high priority. Finally, most of the other demands (service, sales and auctions) for parts may have a lower priority.
