A Brake Pad has 5 processes that will undergo before it will be produced at a particular point in time. The jobs are labeled A, B, C, D and E in the order that they entered the shop. The respective processing times and due dates are given in the table below.
| Job Sequencing | Processing Time | Due Date |
| A (Turning) | 6 | 8 |
| B (Drilling) | 2 | 6 |
| C (Griding) | 8 | 18 |
| D (Milling) | 3 | 15 |
| E (Facing) | 9 | 23 |
15. Using EDD priority technique determine the sequence of the jobs
| BADCE | ||
| BACED | ||
| BCEAD | ||
| BECAD |
16. Using EDD priority technique determine average flow time
| 14.25 | ||
| 16.82 | ||
| 13.60 | ||
| 15.40 |
17. Using CR priority technique determine the sequence of the jobs. Assume none of the jobs have been started yet and you are at day "0".
| CAEBD | ||
| ABEDC | ||
| ACEBD | ||
| CABDE |
18. Using CR priority technique determine the average days late
| 4.5 | ||
| 6.4 | ||
| 2.9 | ||
| 2.2 |
19. As per the calculations, which of the two priority techniques EDD or CR is best sequencing option for the Brake Pad process? Why?
