Assuming that p=2, v=1.25, g=0.50, B=0.50 If demand is characterized by the empirical probability distribution given below, what is the optimal profit? D f(D) 12 0.1 13 0.4 14 0.2 15 0.2 16 0.1
Cu = 2 - 1.25 = 0.75
Co = 1.25 - 0.5 = 0.75
Critical fractile = Cu/(Cu+Co) = 0.75/(0.75+0.75) = 0.5
Refer cumulative probability distribution table to lookup for f(D) greater than 0.5
D | f(D) | ∑f(D) |
12 | 0.10 | 0.10 |
13 | 0.40 | 0.50 |
14 | 0.20 | 0.70 |
15 | 0.20 | 0.90 |
16 | 0.10 | 1.00 |
Correspodning value of f(D) = 0.7 which is greater than 0.5
Therefore,for optimal order quantity, Q = 14
Expected shortage, L = (15-14)*.2+(16-14)*.1 = 0.4
Average demand, D' = 12*.1+13*.4+14*.2+15*.2+16*.1 = 13.8
Average sales, S = D' - L = 13.8-0.4 = 13.4
Expected leftover, V = Q - S = 14 - 13.4 = 0.6
Expected profit = S*Cu - V*Co = 13.4*0.75 - 0.6*0.75 = 9.6
