Transcribed Image Text:2. Be sure that Solver is installed.
3. Use Solver to determine the optimum schedule for part-time servers for the
weekday schedule at the Raleigh, North Carolina restaurant.
4. Solver for Option 1, in which you want the objective (Cell D16) to have the
minimum (Min) number of employees scheduled by changing the number of
employees (D4:D9). Make sure to add the constraints below:
a. The first constraint is to be sure that you have enough (>=) employees
(E11:Q11) to meet expected demand (E13:Q13)
b. The second constraint is to be sure that only whole numbers are used for
the Employees (D4:D9) (because you cannot schedule part of a person to
work).

Expert Solution
Step 1
Develop a spreadsheet as shown below and use excel solver to find the optimal schedule of employees.
Note that the given results are not optimal. It is because in the given solution, 24 employees have to work for 96 hours while the derived solution makes the schedule for 98 hours. THis is because the given solution has not met the requirements completely. It can be noticed that at 8:00 - 9:00 schedule there is a shortage.
The optimal solution is shown as below.
