Exam 16: Scheduling

The operations manager of a body and paint shop has five cars to schedule for repair. He would like to minimize the makespan to complete all work on these cars. Each car requires body work prior to painting. The estimates of the times required to do the body and paint work on each are as follows: What is the makespan for the optimal schedule?

The owner/operator of the local franchise of Handyman, Inc., has four jobs to do today, shown in the order they were received: If he uses the earliest due date first priority rule to schedule these jobs, what will be the average job tardiness?

A Gantt chart is a basic scheduling tool that is most useful in low-volume systems.

Scheduled due dates are the result of

Eva, the owner of Eva's Second Time Around Wedding Dresses, currently has five dresses to be altered, shown in the order in which they arrived: If Eva uses the shortest processing time first priority rule to schedule these jobs, what will be the average number of jobs in her shop today?

A major difference between manufacturing and service systems in terms of scheduling is

Loading is the determination of which work centers should perform which jobs.

When orders exceed our capacity, priority rules are used to select which orders will be accepted.

Which of the following is not a measure for judging the effectiveness of a schedule sequence?

Job X, which has a duration of four days, is due by the close of business on Friday, December 23. Without looking at the work already at X's required resource, the scheduler schedules X to be begun immediately and assumes that X will be done four days from now. This is an example of

A scheduling technique used to achieve an optimum matching of tasks and resources is

The president of a consulting firm wants to minimize the total number of hours it will take to complete four projects for a new client. Accordingly, she has estimated the time it should take for each of her top consultants-Charlie, Betty, Johnny, and Rick-to complete any of the four projects, as follows: Assume there must be one-to-one matching between consultants and projects. For the optimal schedule, what is the total number of hours it will take these consultants to complete these projects?

There are four resources and four jobs to be done. Assume there must be one-to-one matching between jobs and resources. The time required for each resource to do each job is as follows: For the optimal schedule, what is the total number of hours required to complete these jobs?

Accordingly, she has estimated the time it should take for each of her top consultants-Charlie, Betty, Johnny, and Rick-to complete any of the four projects, as follows: Assume there must be one-to-one matching between consultants and projects. What is the optimal assignment of consultants to projects?

Accordingly, she has estimated the time it should take for each of her top consultants-Charlie, Betty, Johnny, and Rick-to complete any of the four projects, as follows: Assume there must be one-to-one matching between consultants and projects. After the row and column reductions, what is the resulting entry in the new table for assigning Rick to project D?

High-volume jobs that often follow the same sequence are known as

As long as the bottleneck operations are used effectively, idle time in non-bottleneck operations will not affect the overall productivity of the system.

Priority rules are widely used to sequence jobs in high-volume systems.

Job X arrived at work center Q at noon. At 2 p.m. that same day X was begun. X left work center Q at 3:15 p.m. that same day. X's flow time, in minutes, was

Accordingly, she has estimated the time it should take for each of her top consultants-Charlie, Betty, Johnny, and Rick-to complete any of the four projects, as follows: Assume there must be one-to-one matching between consultants and projects. In how many different ways can she assign these consultants to these projects?
