Fig. 14.1 The framework of multicriteria decision making for life cycle sustainability
assessment.
After determining the interval life cycle sustainability performance
matrix (see Table 14.2), there are three criteria in social pillar including
SB, CED, and FS are benefit-type criteria, and the other five criteria are
cost-type criteria.
As for the data with respect to the benefit-type criteria, they can be nor-
malized. Taking the data with respect to FS as an example:
0:25 0:25 0:25 0:25
¼ 00 (14.1)

9:75 0:25 9:75 0:25
