Live product output a TOPSIS ranking with its full normalization, weighting and distance trace one tab away.
No black boxes. Normalized matrices, ideal solutions, outranking flows, credibility indexes each intermediate result is a table you can inspect and export.
Set weights by hand, derive them from pairwise judgments with AHP including criteria hierarchies and multi-participant groups or let CRITIC compute objective weights from the data itself.
TOPSIS, VIKOR, PROMETHEE I/II, ELECTRE III, WASPAS, COPRAS, EDAS and fuzzy TOPSIS compare them side by side and test how stable your winner is under weight and data changes.
Copy any result table ranking or any trace step as booktabs LaTeX, grab ready-made BibTeX for every method, and export the complete analysis to Excel or PDF.
Deterministic engines and fixed-seed Monte Carlo: identical inputs give identical reports. A share link encodes the whole analysis so a reviewer can replay your exact run.
Weight sensitivity with exact flip points, ±noise data perturbation, and a leave-one-out rank-reversal check the stability analysis reviewers ask for, out of the box.
