Computing the interval weights.

Proxy	(%)	(%)	Interval (%)
EF	16.1	11.4	13.7
UR	1.9	9.2	5.5
INF	4.0	9.5	6.8
INFRA	8.1	10.0	9.1
CPI	27.2	11.5	19.4
PI	27.2	11.6	19.4
RL	8.1	10.9	9.5
SD	1.9	8.5	5.2
KC	4.0	9.4	6.7
CO2E	1.9	8.1	5.0

¹Defuzzified Weights. ²Expert weights based on the survey responses of the experts, adjusted for alpha values. The values in bold are the interval weights which are the final weights to be applied to composite indices after integrating expert opinion with the FAHP method.
