Level A 7. Modify the employee scheduling model so that em- ployees are paid $10 per hour on weekdays and $15 per hour on weekends. Change the objective so that you now minimize the weekly payroll. (You can as- sume that each employee works eight hours per day.) Is the previous optimal solution still optimal? 14. SureStep is currently getting 160 regular-time hours from each worker per month. This is actually calculated from 8 hours per day times 20 days per month. For this, they are paid $9.375 per hour (=1500/160). Suppose . workers can change their contract so that they only have to work 7.5 hours per day regular-time- everything above this becomes overtimeand their regular-time wage rate increases to $10 per hour. They will still work 20 days per month. Will this change the optimal no-backlogging solution? 16. Suppose SureStep could begin a machinery upgrade and training program to increase its worker productivity. This program would result in the following values of labor hours per pair of shoes over the next four months: 4, 3.9, 3.8, and 3.8. How much would this new program be worth to SureStep, at least for this four-month planning horizon with no backlog- ging? How might you evaluate the program's worth beyond the next four months
