Exam 18: Short-Term Scheduling

Delta uses mathematical short-term scheduling techniques and a high-tech nerve center to manage the rapid rescheduling necessary to cope with weather delays and similar disruptions.

The correct sequence from longest to smallest duration scheduling is

At Morgan's Transformer Rebuilding, a set of five jobs is ready for dispatching to a machine center. The processing times and due dates for the jobs are given in the table below. Use shortest processing time to sequence the jobs, and calculate the average completion time, the average job lateness, and the average number of jobs in the machine center. Job Work Time (days) Due Date (days) A 15 38 B 13 28 C 7 20 D 18 50 E 9 15

The priority rule that sequences jobs using the smallest ratio of due date from today to processing time is

Which of these is not part of the planning files of a production planning and control system?

Which of the following is an aid used to monitor jobs in process?

Five jobs are waiting to be processed. Their processing times and due dates are given below. Using the earliest due date dispatching rule, in which order should the jobs be processed? Job Processing Time (days) Job due date (days) A 4 7 B 2 4 C 8 11 D 3 5 E 5 8

The sequence of decisions that affect scheduling is

The word "finite" in finite capacity scheduling refers to the use of finite or limited capacity rather than unlimited capacity.

How does short-term scheduling vary among the different process choices? Specifically, compare short-term scheduling at process-oriented, work cells, repetitive, and product-focused facilities.

What are the options available to operations personnel to manage facility work flow?

A practitioner of family medicine begins her day with five patients needing urgent care. She does a very brief assessment of what each patient appears to need and estimates the time required of each. None of the cases is life-threatening, and so she determines to take the five in the order that they arrived at the clinic. The data for these patients, in the order they arrived, is Patient A, 30 minutes; Patient B, 40 minutes; Patient C, 10 minutes; Patient D, 50 minutes; and Patient E, 15 minutes.a. If it is now 8:00 a.m., at what time will the doctor be finished with all five of these emergencies? b. How much time will the five patients have collectively spent waiting? c. How much less time would have been spent waiting if the doctor had taken the patients according to shortest processing time?

A work center is interested in limiting work-in-process by not allowing production to start again until the current batch is finished. The best solution most likely involves

__________ determine the sequence of jobs in process-oriented facilities.

Forward scheduling is the scheduling of

What makes short-term scheduling of strategic importance?

The jobs listed below needed to be completed. Assume that it is now day 140. If the jobs are sequenced according to shortest processing time rule, what is the average completion time? Job Processing Time (days) Job due date (days) A 20 180 B 30 200 C 10 175 D 16 230 E 18 210

What is the difference between a Gantt load chart and a Gantt scheduling chart?

If job 5 takes 3, 4, or 5 hours to be completed by workers A, B, and C, respectively, what would the row values for job 5 be after performing Step 1A of the assignment method?

Forward scheduling
