The copy center has a job order that requires 500 pages of white paper and 200 pages of pink paper. The copying rate is 25 pages per minute, the overall setup time is 5 minutes, and the color change time is 2 minutes. The routing for the job also calls for stapling and three-hole drilling (in that order). The time standards are 10 minutes and 20 minutes, respectively. If labor cost is charged on the basis of total standard time multiplied by $6.00 per hour, estimate the cost of this job, including the work in Problem 1.

$6.50 per job Throughput time = 5+(700/25)+2+10+20= 65 minutes (65/60)* $6.00= $6.50

The copy center has a job order that requires 500 pages of white paper and 200 pages of pink paper. The copying rate is 25 pages per minute, the overall setup time is 5 minutes, and the color change time is 2 minutes. What is the hourly copy center capacity to do jobs like this one? (Assume that the setup must be done for every job of this type).

1.5 or more jobs per hour, but less than 2 jobs per hour

Shanice's hair salon is one of the best salons in town. However, Shanice is the only person working in the salon and the process for getting a haircut involves shampooing, cutting and then styling. If it takes Shanice 10 minutes to shampoo, 15 minutes to cut and 20 minutes to style hair, how many haircuts can Shanice do in one 8 hour-shift (assuming that she works continuously, and stops after 8 hours)?

10 haircuts

The copy center has a job order that requires 500 pages of white paper and 200 pages of pink paper. The copying rate is 25 pages per minute, the overall setup time is 5 minutes, and the color change time is 2 minutes. If the job has to wait in queue at the copy work center for 24 minutes, at the stapling work center for 43 minutes, and at the three-hole drilling work center for 17 minutes, what is the throughput time for this job? (These queue times apply only to this question!)

149 minutes Throughput time = 5+(700/25)+2+10+20+24+ 43+17= 149 minutes

The copy center has a job order that requires 500 pages of white paper and 200 pages of pink paper. The copying rate is 25 pages per minute, the overall setup time is 5 minutes, and the color change time is 2 minutes. Suppose the copy center only did jobs exactly like this one (500 white, 200 pink). What would the cycle time be? Assume that different people work in each of the three work centers.

Scraping the 100 invitations is an example of prevention costs for quality management.
