NOTE ON "THE INFLUENCE OF SETUP TIME ON JOB SHOP PERFORMANCE" BY WILBRECHT AND PRESCOTT.

The author comments on the article "The Influence of Setup Time on Job Shop Performance," by J. K. Wilbrecht and W. B. Prescott, published in the December, 1969 issue. The author asserts that Wilbrecht and Prescott mischaracterized machine setup operations in job shops. The author explains that setting up manufacturing equipment for a new job may involve dismantling the old setup as well as setting up for a new job, so time for both aspects should be accounted for. Other times, the changeoever is simpler and faster. The author also suggests that other aspects of the article do not reflect real-world conditions.
