a) What is the optimal size of the production run? _ units (round your response to the nearest whole number).
b) What is the average holding cost per year? (round your response to two decimal places).
c) What is the average setup cost per year? (round your response to two decimal places).
d) What is the total cost per year, including the cost of the lights? (round your response to two decimal places).
Annual demand (D) = 11900 lights
Set up cost(S) = $49
Holding cost (H) = $0.10
Production rate (p) = 95 lights per day
Demand rate (d) = D/number of days per year = 11900/300 = 39.667 lights per day
Cost per light(C) = $0.95
A) Optimum production quantity(Q) = sqrt of {2DS / H [1-(d/p)]}
= sqrt of {(2x11900x49) /0.10[1-(39.667/95)]}
= Sqrt of [1166200 / 0.10(1-0.4175) ]
= sqrt of [1166200/(0.10 x 0.5825)]
= sqrt of (1166200/0.05825)
= Sqrt of 20020600.8583
= 4474 lights
B) I - max = (Q/p) (p-d) = (4474/95)(95-39.667) = 47.09 x 55.333 = 2605.63 lights
Average holding cost per year = [(I-max / 2) H] = (2605.63/2)0.10 = $130.28
C)Average setup cost per year = (D/Q) S = (11900/4474)49 = $130.33
D) Cost of lights per year = D x C = 11900x$0.95 = $11305
Total cost per year = Holding cost + setup cost + cost of lights
= $130.28 + $130.33 + $11305
= $11565.61
