Answer:
Answer is explained in the explanation section below.
Step-by-step explanation:
Solution:
Board-Feet = Mean + Z*SD
Where SD = Standard Deviation
Mean = 40,000;
SD= 15,000;
Z = NORMSINV(SL); SL (Service Level) = Cu/(Cu + Co)
1.
Solution:
Cu = $(4 - 3.35 + 2)
Since he would gain $4 - $3.35 by substituting lumber for conventional wood, he would lose $2 in goodwill and credibility loss.
Cu = 2.65
And,
Co = (4 - 2 + 4% x 4)
Since half of the lumber becomes scrap after three months and he pays 4% as a holding cost for keeping $4/unit as inventory, he incurs a holding cost of 4%.
Co = 2.16
Service Level SL = Cu/(Cu+Co)
Service Level SL = 2.65/(2.65+2.16)
Service Level SL = 0.550936
Z = NORMSINV(0.550936)
Z = 0.12
Hence,
Board-Feet = Mean + Z*SD
Board-Feet = 41,920.38
2.
Solution:
Cu = $(2 - 4.2 + 3.2)
Since he would gain $4.2-$3.2 by substituting lumber for conventional wood, he would lose $2 in goodwill and credibility loss.
Cu = 1
In the event of overstocking, he does not specify the price at which he will replace FSC lumber with conventional lumber. Only his price, which is $3.2/board-foot for traditional lumber, is issued.
Co = 4 - 3.4
since he'll have to market the excess FSC lumber inventory at conventional wood's price; ASSUMING traditional lumber rate at the rate $3.4/board-feet
Co = 0.6
So,
Service Level SL = Cu/(Cu+Co) = 1/(1+0.6)
SL = 0.625
Z = NORMSINV(0.625)
Z = 0.318639
Board-Feet = 44,779.59
3.
Solution:
Here, everything will be same except the formula for calculate the Board -Feet. New formula is:
Board-Feet = Mean +
Here, n = 10
Just plugging in the values, we get:
Board-Feet = 40,000 +
Board-Feet = 41,511.44
