(a)
Cost of overbooking one less than the cancellation,
Cu = Cost of an empty room = 145
Cost of overbooking one more than the cancellation, Co =
Cost of a dishonored guest = 205
So,
The optimal service level = Cu / (Co + Cu) = 145 / (205+145) = 0.414
d | P(d) | F(d) |
0 | 0.07 | 0.07 < 0.414 |
1 | 0.07 | 0.14 < 0.414 |
2 | 0.10 | 0.24 < 0.414 |
3 | 0.02 | 0.26 < 0.414 |
4 | 0.12 | 0.38 < 0.414 |
5 | 0.01 | 0.39 < 0.414 |
6 | 0.04 | 0.43 < 0.414 |
7 | 0.19 | 0.62 > 0.414 |
8 | 0.16 | 0.78 |
9 | 0.22 | 1.00 |
The F(d) is >= 0.414 at d=7, so, the optimum overbooking level = 7
(b)
d | P(d) | Empty rooms | # disnonored |
0 | 0.07 | 0 | 7 |
1 | 0.07 | 0 | 6 |
2 | 0.10 | 0 | 5 |
3 | 0.02 | 0 | 4 |
4 | 0.12 | 0 | 3 |
5 | 0.01 | 0 | 2 |
6 | 0.04 | 0 | 1 |
7 | 0.19 | 0 | 0 |
8 | 0.16 | 1 | 0 |
9 | 0.22 | 2 | 0 |
So, the expected number of empty rooms = 1*0.16 + 2*0.22 = 0.60
and the expected number of dishonors = 7*0.07 + 6*0.07 + 5*0.1 + 4*0.02 + 3*0.12 + 2*0.01 + 1*0.04 = 1.91
So,
The expected loss = 0.60*145 + 1.91*205 = $478.55
