Problem
We now extend the model as seen in Sched2 by adding another factor. When deciding which employee
goes on which schedule, the amusement park decides to let the seniority of the employees affect the
decision. The seniority is simply measured in years of employment at the park. How should the company
assign the schedules to the employees?
Solution
The solution is almost identical to the one in Sched2. The difference is that instead of just adding the
preferences, we now weight them by multiplying each preference by the employee's seniority.
Remarks
There are many ways of adjusting for seniority and other factors. By increasing and decreasing the size of
the seniority factors, you can adjust the importance of the seniority to the desired level.
