The following table gives the operation times and due dates for five jobs that are to be processed on a machine. Assign the jobs according to the shortest operation time and calculate the mean flow time.
Job | Processing Time | Due Date (Days Hence) |
101 102 103 104 105 | 6 days 7 days 4 days 9 days 5 days | 5 3 4 7 2 |
Short Answer
The mean flow time using the shortest process assignment rule is 18.6.
