SCENARIO-FUZZY-MEREC - component-scenario reference profile (non-canonical)

1. 1. Validate and capture the supplied ordered TFN input and criterion metadata.

   $$X=(X^L,X^M,X^U),x^L\le x^M\le x^U$$

2. 2. Run crisp MEREC independently on the Lower, Middle, and Upper TFN component inputs.

   $$w^{(s)}=MEREC(X^{(s)}),s\in \{L,M,U\}$$

3. 3. Average the three crisp component weights, normalize, and disclose whether the fuzzy envelope changed the result.

   $$w=normalize((w^{(L)}+w^{(M)}+w^{(U)})/3)$$
