By using the midpoint values given in Table 8.2, column 2, the resulting equations for the individual items
are calculated in column 3. The cost items for each of the three categories are added together to provide
the total cost for each category. The equations for estimating the costs for each of the categories are as
follows:
DMC = C RM + C + C + 1.33C + 0.069FCI + 0.03COM
OL
UT
WT
FMC = 0.708C + 0.068FCI + depreciation
OL
GE = 0.177C + 0.009FCI + 0.16COM
OL
We can obtain the total manufacturing cost by adding these three cost categories together and solving for
the total manufacturing cost, COM. The result is
(8.1)
In Equation (8.1), the depreciation allowance of 0.10FCI is added separately.
