Complex Fermatean fuzzy sets (CFFSs) is one of the successful extension of complex Pythagorean fuzzy sets (CPFSs). The main objective of the paper is to present the notion of complex Fermatean fuzzy sets (CFFSs), and some of their basic operational laws and their corresponding operators, which can represent the time-periodic problems and two-dimensional information in a single set. We introduce various novel methods, namely complex Fermatean fuzzy Einstein weighted geometric (CFFEWG) operator, complex Fermatean fuzzy Einstein ordered weighted geometric (CFFEOWG) operator, complex Fermatean fuzzy Einstein hybrid geometric (CFFEHG) operator, induced complex Fermatean fuzzy Einstein ordered weighted geometric (I-CFFEOWG) operator, and induced complex Fermatean fuzzy Einstein hybrid geometric (I-CFFEHG) operator along with their structure properties, such as idempotency, boundedness and monotonicity. An illustrative example related to the selection of the more suitable location for hospital is to be considered to show the effectiveness and efficiency of the novel approach. |
