The set-up time for jobs on some multi-station machines, such as manually configured colour printers, are sequence dependent. Many techniques exist for finding a sequence in which to process the jobs to reduce total set-up time significantly. They all require an estimate ofthe set-up time for each job given the set-up of the previous job. In practice predicting set-up times for scheduling purposes may become prohibitively time consuming. In this article a practical technique is presented that estimates the set-up time for a job on a multi-station machine, such as a manually configured printer. An application in a corrugated cardboard box factory, where the technique is in use as part of a computerised scheduling system, is discussed.
