Joan Bennett, the production manager at the Red, White, and Blue
Fireworks Company (RWBFC), has decided to change the work schedule
for her manufacturing employees. Because of high product demand and
an inability to expand at the current facility, RWBFC needs to
operate ten hours each day, seven days each week. In order to avoid
the use of overtime and to keep her employees fresh, Joan decided
to have employees work four tenhour shifts each week. She insists
that every employee must have three consecutive days off. The work
week begins on Monday and ends on Sunday. The manufacturing process
requires a minimum of 20 employees. Joan has asked you to develop a
staffing plan that will determine the exact number of full-time
employees needed, as well as the schedule each employee will need
to work. Remember, each employee must have three consecutive days
off. Joan also has asked you to determine which other factors you
consider relevant in making the transition to the new schedule. In
particular, she is very interested in a method for determining
which employees work which schedule and how to implement the new
schedule with minimal dissatisfaction.

(a) Develop a staffing plan for RWBFC in accordance with the
constraints stated above. (b) Explain the method used in developing
your plan. (c) Explain how employees should be assigned to the
different schedules. (d) Discuss any concerns you have with the new
staffing plan.
