Weighted decision matrix
Compare venues, courses or equipment with your own criteria, weights and ratings. Inspect score breakdowns, test weight changes and export a comparison report locally.
3. Compare the outcome
Your inputs stay in this tab. Save editable JSON before closing; CSV and the report cannot be imported back here.
How to use
- Name the options and criteria, or load the venue example.
- Set weights and optional minimum ratings; score every option with 10 meaning best.
- Review ranks and contributions, try a weight scenario, then export CSV/report and save editable JSON.
Before you start
2–12 options and 1–12 criteria. Rate desirability from 0 (worst) to 10 (best), whole numbers; for cost, a lower cost should get a higher desirability rating. Weights are whole numbers 0–100 and normalized automatically. Total score = sum(rating × weight) / sum(weights) × 10. Optional minimum ratings exclude options that fail any requirement, including zero-weight criteria. Missing required ratings block the entire ranking; blank zero-weight ratings without a minimum are ignored. Ties share rank before display rounding. Example: ratings 9,5,7 with weights 4,4,2 score 70/100. Sensitivity changes one raw weight while others stay fixed; it is a scenario, not a prediction. Results reflect your judgments, not objective recommendations. No prices, research or collaborative scoring supplied. CSV uses a decimal point and protects formula-like text. JSON up to 1 MB, 30 undo steps; save explicitly before closing. No automatic storage.
