Example 2.2 Calculation of the Plant Cost Index from Component Indexes

Calculate the plant cost index using the component cost indexes in 1998 from Ta-
ble 2.12 and the fractional contribution of each component from Figure 2.6.

I = 0.61 [ 0.37 (382.8) + 0.14 (430.8) + 0.20 (534.8) + 0.07 (365.8) + 0.07 (648.5)

+ 0.05 (333.6) + 0.10 (394.3) ]+ 0.22 (287.4) + 0.07 (374.2) + 0.10 (341.2)

= 389.5

The plant cost from Table 2.12 is 389.5, which agrees with the calculated value.
