“…Form the results, it is found that sustainable process selections using clustering theory corroborate that from sustainability footprint (D e ), which uses Euclidian distance. In our previous work, different method of sustainable process selection has been compared for the ASR data (Sikdar et al 2017). Results from sustainability footprint (D e ), vector norm, Canberra distance, zCanberra distance, and Mahalanobis distance show similar ranking of process options in order of their sustainability.…”
