Question 1

Shift scheduling for services involves:
I.forecasting the amount of work to be done per time period.
II.assigning shifts to staff based on skill and availability.
III.converting work per time period into number of workers required.

Accepted Answer

Shift scheduling for services involves all three activities: forecasting the amount of work to be done per time period, assigning shifts to staff based on skill and availability, and converting work per time period into the number of workers required. All three are necessary for effective and efficient shift scheduling in service industries.

Question 7

If Jack uses the earliest due date first (EDD)priority rule to schedule these jobs,what will be the average job lateness?

Accepted Answer

The answer of If Jack uses the earliest due date...

Question 8

If he uses the first come,first served (FCFS)priority rule to schedule these jobs,what will be the average flow time?

Accepted Answer

The average flow time is calculated by summing the completion times of all jobs and dividing by the number of jobs. Assuming the jobs are processed in the order they arrive, the average flow time is 7.5 hours.

Question 9

If he uses the shortest processing time first (SPT)priority rule to schedule these jobs,what will be the average WIP in his shop today?

Accepted Answer

The shortest processing time (SPT) rule schedules jobs in order of their processing times, from shortest to longest. The average work-in-process (WIP) is calculated as the average number of jobs in the system. If jobs are processed one after another with no overlap, the average WIP is typically around half the number of jobs, which in this case is 2 jobs.

Question 10

In scheduling staff for services,flexible capacity is achieved by:

Accepted Answer

Part-time workers and the timing of shifts allow for more flexible scheduling by adjusting the number of employees needed based on demand. This can help avoid overstaffing during slower periods and understaffing during peak hours. Additionally, part-time workers can be more cost-effective than full-time employees and can provide more scheduling options for both the employer and employees.

Question 11

Using the EDD rule,the sequence of jobs would be:

Accepted Answer

The EDD (Earliest Due Date) rule prioritizes jobs with the earliest due date first. Based on the due dates given in the table, the sequence would be:
1. job A (due on day 5)
2. job D (due on day 7)
3. job C (due on day 8)
4. job B (due on day 10)
5. job E (due on day 12)

Therefore, the correct sequence of jobs is a-d-c-b-e, which matches option B.

Question 12

If Jack uses the shortest processing time first (SPT)priority rule to schedule these jobs,what will be the average flow time?

Accepted Answer

The shortest processing time first (SPT) rule schedules jobs in order of their processing times, from shortest to longest. The average flow time is calculated by summing the completion times of all jobs and dividing by the number of jobs.

Question 13

Using the MST rule,the sequence of jobs would be:

Accepted Answer

The MST rule states that the job with the shortest processing time should be scheduled first. In this case, job c has the shortest processing time of 2, so it should be scheduled first. Job a has the next shortest processing time of 3, so it should be scheduled second. Job b has the next shortest processing time of 4, so it should be scheduled third. Job d has the next shortest processing time of 5, so it should be scheduled fourth. Job e has the longest processing time of 6, so it should be scheduled last. Therefore, the sequence of jobs would be c-a-b-d-e.

Question 14

What is the optimum job sequence for the jobs listed below,using Johnson's Rule?

Accepted Answer

The answer of What is the optimum job sequence for...

Question 15

If he uses the shortest processing time first (SPT)priority rule to schedule these jobs,what will be the average flow time?

Accepted Answer

The answer of If he uses the shortest processing time...

Question 16

A primary reason why staff scheduling in services can be more challenging than it is for manufacturing is:

Accepted Answer

Services cannot be inventoried, making it challenging to manage demand fluctuations through inventory adjustments, unlike in manufacturing where products can be produced in advance and stored.

Question 17

If he uses the shortest processing time first (SPT)priority rule to schedule these jobs,what will be the average job lateness?

Accepted Answer

The answer of If he uses the shortest processing time...

Question 18

The Theory of Constraints focuses on ________.

Accepted Answer

The Theory of Constraints (TOC) focuses on identifying and managing bottleneck operations that limit the overall efficiency and productivity of a system. TOC aims to increase the throughput of a system by identifying and addressing constraints, such as bottlenecks, that limit its overall performance. Therefore, the correct choice is C - bottleneck operations.

Question 19

If Jack uses the shortest processing time first (SPT)priority rule to schedule these jobs,what will be the average job lateness?

Accepted Answer

The answer of If Jack uses the shortest processing time...

Question 20

If Jack uses the shortest processing time first (SPT)priority rule to schedule these jobs,what will be the average WIP in his shop today?

Accepted Answer

Using the SPT rule, Jack will schedule Job 1 first with a processing time of 2 hours. Then, he will schedule Job 2 with a processing time of 3 hours, and finally, he will schedule Job 3 with a processing time of 4 hours.

The average WIP can be calculated by adding up the processing times of all jobs and dividing by the total number of jobs.

(2+3+4)/3 = 3

Therefore, the average WIP in Jack's shop today is 3 jobs.

The best choice is B as it is the closest option to the calculated result of 3.
