Cs = Cost of shortage = 150-75 =75
Ce = Cost of excess = 75-60 =15
Service level = Cs / Ce+Cs = 75/90 = 0.833
which corresponds to a z value of 0.97
Optimum value of quantity = 100+30x0.97 =129
Expected lost sales with this quantity = L(0.97) = 0.089
Expected lost sales = SD x L(z) = 30x0.088 =2.64 =3
Expected sales = Mean - Expected lost sales = 100-3 =97
Expected leftover inventory = Order quantity - expected sales = 129-97 = 32
Profit = Cs x Expected sales- Ce x Expected leftover inventory
= 75 x97 - 15 x32 = 7275-480 = 6795
cost of holding unsold inventory = 32x 10 =320
Net profit = 6795-320 = 6475
Option 2 is the closest answer.
In the previous problem, the manufacturer performs additional market research. Based on this research, they determine that they can increase the price to $150 and are able to reduce the standard devi...
