Abstract: New possibilities and challenges have evolved in the setting of the software engineering sector’s rapid transition to Industry 5.0, wherein sustainability takes centre stage. Appropriate evaluation approaches are required for analysing the long-term viability of software engineering practices within this paradigm. This study proposes an innovative approach to evaluating sustainability in software engineering within Industry 5.0 by utilising the fuzzy technique for order of preference by similarity to ideal solution (fuzzy TOPSIS) methodology. The fuzzy TOPSIS approach is effective at accounting for the inherent uncertainties as well as imprecisions related to sustainability...
