An aggregation model via fuzzy linear programming to rank the objects with multiple attributes

Fuzzy aggregation models via fuzzy data envelopment analysis (FDEA) are proposed for ranking entities with multiple attributes and multiple evaluators. Because the weight factors of attributes of entities evaluated in aggregation models are sought by fuzzy data envelopment analysis (FDEA) not predetermined by decision-makers, the proposed aggregation models can be regarded as fair-competition ones so that the inherent preference of evaluators can be objectively reflected.
