Gerald Glynn manages the Michaels Distribution Center. After careful examination of his database information, he has determined the daily requirements for part-time loading dock personnel. The distribution center operates 7 days a week, and the daily part-time staffing requirements are
| Day | M | T | W | Th | F | S | Su |
|--------------|---|---|---|----|---|---|----|
| Requirements | 4 | 3 | 4 | 5 | 7 | 4 | 4 |
Find the minimum number of workers Glynn must hire. Prepare a workforce schedule for these individuals so that each will have 2 consecutive days off per week and all staffing requirements will be satisfied. Give preference to the S-Su pair in case of a tie. (Note: If there is a tie that cannot be broken by following the S-Su pair, choose the pair closest to the beginning of the considered week.)
The minimum number of workers is 7 workers. (Enter your response as a whole number.)
Specify the workforce schedule for each employee by indicating the day offs (other days are considered to be work days.) Make sure to give preference to the S-Su pair in case of a tie. (Note: If there is a tie that cannot be broken by following the preference to the S-Su pair, choose the pair closest to the beginning of the considered week, with Monday being considered as the first day of the week.)
