The number of tubs required to circulate among the cancelling machine and the sorting clerks is to be computed. Concept Introduction: The existing capacity of each tub is 375 letters. The automated sorting machine takes about 375 seconds for reading each tub. The additional information is that 90,000 letters are to be processed during an 8 hourshift; the sum of average waiting time and materials handling time is 25 minutes for each tub, and, the safety stock policy variable, a is 0.18.

A U.S. Postal Service supervisor is looking for ways to reduce stress in the sorting department. With the existing arrangement, stamped letters are machine-canceled and loaded into tubs with 450 letters per tub. The tubs are then pushed to postal clerks, who read and key zip codes into an automated sorting machine at the rate of one tub per 385 seconds. To overcome the stress caused when the stamp canceling machine outpaces the sorting clerks, a pull system is proposed. When the clerks are ready to process another tub of mail, they will pull the tub from the canceling machine area. How many tubs should circulate between the sorting clerks and the canceling machine if 95,000 letters are to be sorted during a 10-hour shift, the safety stock policy variable, α, is 0.25, and the average waiting time plus material handling time is 30 minutes per tub? The average processing time per tub of letters, p, is nothing day. (Enter your response rounded to four decimal places.) The…
