Challenge Problems

Push your limits with challenges.

Question 1

You are managing a photo copying shop with three machines of varying speeds. Job A takes 1 hour on machine 1, 30 minutes on machine 2, and 45 minutes on machine 3. Job B takes 2 hours on machine 1, 90 minutes on machine 2, and 1 hour on machine 3. Devise a schedule that minimizes total completion time considering these parameters.

💡 Hint: Use a comparative chart to weigh machine speeds against jobs.

Question 2

In a scenario where job deadlines overlap, propose a method to batch jobs that require similar processing times for more efficient scheduling.

💡 Hint: Think about grouping tasks that share characteristics.
