Capacity planning incorporating job size distribution

A computer-implemented method of determining print capacity, the method comprising:

• receiving a maximum job speed for a document processing device;
• receiving information pertaining to a plurality of jobs performed by the document processing device, wherein the information for each job comprises a job speed and a job size;
• identifying, via a processor, a set of first jobs and a set of second jobs from the plurality of jobs, wherein each first job has a job speed greater than a percentage of the maximum job speed, and wherein each second job has a job speed less than the percentage of the maximum job speed;
• determining, via the processor, a job size threshold based on the job sizes for the first jobs and the job sizes for the second jobs;
• in response to determining the job size threshold, obtaining, via the processor, a linear function based on one or more second jobs, wherein the linear function comprises a function of job speed based on job size;
• repeating the receiving a maximum job speed, receiving information, identifying, determining, and obtaining operations for one or more document processing devices in a document processing environment:
• determining, via the processor, a device capacity function for each document processing device based on the obtained linear function and the job size threshold for the document processing device;
• and
• identifying one or more modifications to the document processing environment based on the device capacity functions.

A computer-implemented method of determining print capacity, the method comprising:

• receiving a maximum job speed for a document processing device;
• receiving information pertaining to a plurality of jobs performed by the document processing device, wherein the information for each job comprises a job speed and a job size;
• for each job, classifying, via a processor, the job into one of a plurality of groups based on the job speed for the job;
• determining, via the processor, a job threshold size for a group based on at least the jobs classified within the group;
• and
• in response to determining the job size threshold, applying, via the processor, a regression model to the plurality of groups to determine a function for an expected device capacity based on job size.
