Abstract
Hypergraphs have been applied to analyze system architecture and to represent system partitions. The concept of ordinary hypergraphs was extended to fuzzy and interval-valued fuzzy hypergraphs. In this paper, we extend fuzzy hypergraphs to type-2 fuzzy hypergraphs. Type-2 fuzzy hypergraphs are defined using type-2 fuzzy sets and satisfy the properties of hypergraphs as well as additional properties. We also show that interval-valued fuzzy hypergraphs are a special case of proposed type-2 fuzzy hypergraphs. The properties of type-2 fuzzy hypergraphs are explained using simple examples.
