The Northside Bank is working to develop an efficient work schedule for full$-$time and part$-$time tellers. The schedule $x_i,y_{j}0$ and integer for $i=9,10,11$ and $j=9,10,11,12,1,2,3$

$($b$)$ Solve the LP Relaxation of your model in part $($a$).$ Enter the total cost value under the optimal solution.

Total Cost: $

$($c$)$ Solve for the optimal schedule of tellers. Enter the total number of full$-$time and part$-$time employees required.

If your answer is zero, enter $"0".$

Total Number of Full$-$Time Employees:

Total Number of Part$-$Time Employees:

$($d$)$ After reviewing the solution to part $($c$),$ the bank manager realized that some additional requirements must be $sp$

time employees. Revise your model to incorporate these additional requirements, and solve for the optimal soluti

If required, round your answers to the nearest whole number. If your answer is zero, enter $"0".$

Total Number of Full$-$Time Employees:

Total Number of Part$-$Time Employees:

Total Cost: $

$9$:$00$ a$.$m$.$ to $7$:$00$ p$.$m$.$ The number of tellers necessary to provide adequate customer service during each hour of of

Each full$-$time employee starts on the hour and works a $4-$hour shift, followed by a $1-$hour break and then a $3-$hour sl

hour $($ $$105$ a day$),$ and part$-$time employees cost the bank $$8$ per hour $($ $$32$ per day$).$

$($a$)$ Formulate an integer programming model that can be used to develop a schedule that will satisfy customer servi

time employees coming on duty at the beginning of hour $j.)$

If your answer is zero enter $"0"$ and if the constant is $"1"$ it must be entered in the box.
