Illustrative example: a representative scenario, not a customer story
Bridge Maintenance Prioritization
Rank aging bridge infrastructure for maintenance scheduling based on structural condition, traffic volume, and budget constraints. Compromise programming balances urgency against available resources for optimal allocation.
The decision problem
Fifteen ageing bridges compete for one maintenance budget and a schedule has to be published. Structural condition argues for one order, traffic volume for another and the cost of the work for a third. No option satisfies everything, so the useful answer is the compromise that keeps the worst individual outcome tolerable, not the one with the best average.

Which method, and why
VIKOR is built for exactly that: it balances group utility against individual regret and reports whether the compromise solution is stable. PROMETHEE II runs the same matrix with preference functions, so a small difference in condition rating can be treated as no difference at all instead of a rank change. Entropy sets the weights from the data, so the schedule is not read as chosen by hand.
What you get out
Ranking and scores
Every alternative with its score, its rank and the intermediate matrices that produced them.
Weight sensitivity
One criterion weight moves at a time, so you see exactly where the leader changes.
Method agreement
When more than one ranking method is run, the orders are compared with Spearman rho and Kendall W.
