Value-Centric Decision (MADA)

Rank concept-stage design alternatives by desirability — weighted benefit, cost and risk attributes with optional single-attribute utility (SAU) curves. Pre-populated with an optimized substructure example so the workflow runs end-to-end out of the box.

1. Case

2. Attributes

Weights are entered as integer percentages and must sum to 100% (stored as fractions summing to 1.0). kind sets validation: risk in [1, 10]; cost > 0; benefit ≥ 0. SAU defaults to linear; pick None to fall back to the division-by-sum normalisation.

3. Alternatives

At least two are required. Score fields update automatically as attributes change.
