EcoWise: web-based intelligent sustainability evaluation using TOPSIS (WISE-T)

EcoWise: WISE-T is a free web-based tool that helps users evaluate and rank sustainability projects by considering environmental, economic, and social factors. It is designed for students, researchers, policymakers, and organisations that may not have access to expensive commercial software. The system uses the Technique of Order Preference by Similarity to Ideal Solution (TOPSIS) method, a common approach in multi-criteria decision-making (MCDM). Users first set up a decision matrix with alternatives and criteria. EcoWise then normalizes the data, applies weights to each criterion, and calculates the distance of each alternative from the best and worst solutions. Based on this, the tool produces a ranked list of options. EcoWise’s novelty lies in its lightweight, easy to use, and runs directly in a web browser without installation. It provides clear visual outputs such as weighted matrices and ranking charts, making the decision-making process more transparent, flexible, and aligned with the United Nations Sustainable Development Goals (SDGs).
