"Webhypergraph is obtained from a hypergraph H, by partitioning every edge of H into two sets of vertices, namely the tail and the head of the edge. This concept has been extended to intuitionistic fuzzy hypergraphs. The authors already introduced the concept of intuitionistic fuzzy directed hypergraphs[11].
