RESTAURANT CREW ASSIGNMENT. Burger Boy Restaurant is open from 8:00 A.M. to 10:00 pt. daily. In addition to the hours of business, a crew of workers must arrive one hour early to help set up the restaurant for the days operations, and another crew of workers must stay one hour after 10:00 P.M. to clean up after closing. Burger Boy operates with nine different shifts:

A needs assessment study has been completed, which divided the workday at Burger Boy into eight 2-hour blocks. The number of employees needed for each block is as follows:

Time Block Employees Needed 7AM-9AM 8 9AM-11AM 10

1IAM-1PM 2 1PM-3PM 3PM-SPM 10 S5PM-7PM 20 7PM-9PM 16 9PM-11PM 8

Burger Boy wants at least 40% of all employees at the peak time periods of 11:00 A.M. to 1:00 p.m. and 5:00 P.M. to 7:00 P.M. to be full-time employees. At least two full-time employees must be on duty when the restaurant opens at 7:00 A.M. and when it closes at 11:00 p.m.

* Formulate and solve a model Burger Boy can use to determine how many employees it should hire for each of its nine shifts to minimize its overall daily employee costs.
