A criteria weighting approach by combining fuzzy quality function deployment with relative preference relation

- We associate FQFD with relative preference relation to identify adjusted criteria weights in an FMCDM model.
- By the adjusted criteria weights, we can avoid multiplying triangular or trapezoidal fuzzy numbers, aggregating multiplied fuzzy numbers, and ranking them.
- Adjusted criteria weights substitutes for original criteria weights in FMCDM through relative preference relation, and thus adjusted criteria weights are useful to construct an FMCDM model.
