Question

13. Automating some activities at a nonbottleneck resource simply increases the amount of idle time for that resource without making the process more efficient. True or False?

14. Specialization reduces processing times by making it easier to balance the line. True or False ?

15. C&A Fast Food has four activities in serving a customer: greet customer, take order, process order, and deliver order. Each activity is staffed by one employee (for a total of four employees). The processing time for each activity is given as follows:

Activity	Processing time per customer
Greet customer	2 seconds
Take order	30 seconds
Process order	60 seconds
Deliver order	5 seconds

  

Assume demand is unlimited. To which activity should C&A assign an additional employee in order to increase process capacity?

A. Deliver order

B. Take order

C. Greet customer

D. Process order

16. Which of the following is a drawback of specialization?

A. Increased processing time

B. Increased wage rates

C. Demotivated workers

D. Increased setup times

17. A good way to improve waiting time is to simply turn customers away. True or False?

18. The coefficient of variation of the arrival process is close to one if the arrivals are dependent on each other. True or False?

Answer 1

Ans:

13) True

If the process capacity and efficiency need to be increased automation should be applied to the bottleneck resources.

14) False

Specialization generally reduces the labor utilization and makes it further harder to balance the line.

15) Option D

Process order

In order to increase process capacity additional employee need to be added to the bottleneck resources.

16) Option C

Demotivated workers

The Demotivated workers will the advantage of specialization to be gained by the organization.

17) False

turning customers away during peak demand time will result in a loss of revenue. it is not a good way to improve waiting time .

18) False

The coefficient of variation of the arrival process is close to one if the arrivals are independent of each other.
