Patent ID: 7142937

Claim:
A computer program product for the management of capacity in a wafer fabrication plant comprising a computer program stored on a storage medium, said computer program performing the steps of: (a) calculating a bottleneck capacity factor for an initial product group mix of an initial capacity plan, the bottleneck capacity factor representing available machine hours per a given time period for said initial capacity plan; (b) calculating maximum capacity values for respective product groups of the initial product group mix in the initial capacity plan, each respective maximum capacity value representing a maximum number of wafers of the respective product group output by said fabrication plant per said given time period; (c) algorithmically determining total output values for respective different product group mixes, including for the initial product group mix of the initial capacity plan, subject to said bottleneck capacity factor and said respective maximum capacity values not being exceeded, each total output value representing a sum of individual output values of all the product groups in the respective different product group mixes by said fabrication plant per said given time period; (d) determining a maximum one of said total output values; and (e) providing a modified product group mix, the product group mix being one of said different product group mixes corresponding to said maximum total output value.
