Speed Design speed: The theoretical capacity under perfect running conditions. The speed of the machine as designed, running empty, is the design cycle rate. Capacity: The upper sustainable limit of quality packages passing a point just before warehousing. Run speed: The instantaneous operating rate at a point in time. Output: A packaging line’s output (designated Y) is the exact quantity of quality product passing a point just before warehousing or shipping in a given time. A machine’s or station’s output is the exact quantity of quality product leaving that machine in a given time.Speed Design speed: The theoretical capacity under perfect running conditions.
