Steps to reproduce
- Download the anonymized survey dataset provided in spreadsheet format. - For environmental awareness and reuse practice dimensions, calculate mean scores for each item measured on a 5-point Likert scale. - For pairwise comparison questions, recode the original 1–9 response scale into a symmetric comparison scale, where the midpoint (5) represents equal importance, values approaching 9 indicate increasing importance of the second criterion, and values approaching 1 indicate increasing importance of the first criterion. - Transform the recoded values into pairwise comparison matrices for each respondent. - Aggregate individual matrices to obtain a group-level comparison matrix. - Apply pairwise comparison–based multi-criteria analysis (following the Analytic Hierarchy Process logic) to derive relative importance weights and rankings of the predefined criteria. - Validate consistency ratios and report final criteria weights and rankings as presented in the article.
