Abstract :
For the diversity of the index system, papers propose the concept of absolute equivalence based on the idea of attribute reduction in rough set theory; then the definition of the lambda-equivalence between two index systems which have inclusion relation is given by the fuzzy cluster analysis method. A discriminance is given, and finally a case study.
