Question

1)What is the outcome when a bottleneck resource is augmented with more capacity?

1. Throughput time increases
2. Cycle time decreases
3. The resource with the second least utilization becomes the bottleneck
4. All of the above

2)Which of the following statements are true?

1. Installed capacity in service systems are always based on peak demand
2. Service systems designed to handle average capacity will be more effective
3. Improving effectiveness of a service will require greater investment of capacity
4. None of the above

3)The arrival rate at the second server in a two-stage serial queuing system is

1. Service rate of server 1
2. Same as arrival rate at server 1
3. Minimum of service rate and arrival rate at server 1
4. Cannot be determined

4)In a worker paced assembly line, consider a situation where the daily requirement has suddenly increased. Which of the following statements will be true?

1. The required cycle time will also increase proportionally
2. The minimum number of workstations required will come down
3. The idle times at many workstations will increase
4. It will be possible to handle the new requirement by increasing the available time

5)Which of the following statements will hold good in the case of a system with uncertainty in demand for service and in service times?

1. When the utilization of resources fall it is an indication of greater efficiency of the service
2. It is a good practice to plan for resource utilization levels more than 85%
3. Cost of waiting to get serviced is directly proportional to the cost of providing the service
4. None of the above

Answer 1

Answer 1) All of the above principles are true, there are so many benefits when a bottleneck resource is augmented with more capacity

Answer 2) Improving effectiveness of a service will require greater investment of capacity, this is true is you want to improve effectives of a service a lot capital will be required in order to change the whole structure.

Answer 3) Service rate of server 1 is the answer, the new server will also come as per service rate of server 1

Answer 4) It will be possible to handle the new requirement by increasing the available time, this is true as when the demand will increase there will be increase in available time as well.

Answer 5) None of the above will be suitable in the above case.
