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?
Shortest Processing Time
A scheduling principle that prioritizes tasks or jobs based on the shortest time required to complete them, aiming to minimize total processing time or delays.
Urgent Care
Medical services provided for conditions that require prompt attention but are not life-threatening, often outside traditional hospital settings.
Waiting Time
Waiting time is the duration that a person, object, or data spends waiting to be processed, serviced, or transferred, often analyzed to improve efficiency in operations.
- Understand the significance and strategic value of short-term scheduling.
- Identify the different sequencing principles and their influence on optimizing schedules.
