| Summary: | Sustainability has become new evolution of quality and efficiency indicator for product life cycle. It is generally acknowledge that sustainability is a result from balancing the environmental, economical and social aspect. However, each aspects may expand to different type of parameters involved that cross the system boundary; qualitative and quantitative parameters. Fuzzy logic approach will be applied to deal with the data uncertainty for obtaining the sustainability assessment of hollow fiber membrane module. Fuzzy logic operation will formulate the mapping from inputs to an output. Thus, it will able for intermediate assessment between sustainable and non-sustainable hollow fiber membrane module. Hence, this paper introduces the comprehensive method for assessing sustainability as guide for hollow fiber membrane designer and manufacturer for future sustainability improvement. © (2014) Trans Tech Publications, Switzerland.
