Extending similarity measures of interval type-2 fuzzy sets to general type-2 fuzzy sets
Published 2013“…Similarity measures provide one of the core tools that enable reasoning about fuzzy sets. While many types of similarity measures exist for type-1 and interval type-2 fuzzy sets, there are very few similarity measures that enable the comparison of general type-2 fuzzy sets. …”

Interval type-2 fuzzy sets in supplier selection
Published 2014“…This study introduces a model for solving the supplier selection problem using interval type-2 fuzzy sets. Moreover, the influence of the membership function shape on the results obtained from the model has been investigated on a real-world problem instance tackled by Ordoobadi.…”

A fuzzy set based framework for concept of affinity
Published 2009“…However, the development of fuzzy set or rough set inspires us that an element, which membership degree to a specified set could be multivalent (fuzzy set) and the set boundary could also be undetermined (rough set). …”

A web based survey using fuzzy set model
Published 2010“…Turksen and Wilson (1995) have laid a theoretical ground for the works using a fuzzy set model for preference prediction. A fuzzy set conjoint model has been developed by incorporating fuzzy measurement of evaluations into the vector preference model. …”
