Patent ID: 7810095

Claim:
A system for characterizing performance of print related resources in a document production environment, the system comprising: a plurality of print related resources; a processor in communication with the print related resources; and a processor-readable storage medium in communication with the processor, wherein the processor-readable storage medium contains one or more programming instructions for performing a method of characterizing performance of print related resources in the document production environment, the method comprising: receiving timing information for a plurality of print jobs performed by the print related resources, wherein the timing information comprises, for one or more print jobs, a time period for at least one print related resource to perform at least one operation for the print job; for each of the plurality of print jobs, determining a time interval between a start time of the print job and a completion time of the print job; aggregating the time intervals to generate a service time distribution; determining statistical information associated with the service time distribution; using a queuing model to approximate one or more performance characteristics of the document production environment based on the service time distribution and the statistical information; and displaying one or more of the performance characteristics for the one or more print related resources based on the print related resource performance.
