Properties of Raha's similarity-based approximate reasoning method

A similarity-based approximate reasoning methodology that requires the construction of fuzzy relations was proposed by Raha et al. [26]. This paper investigates properties of four inferred conclusions calculated by Raha's similarity-based approximate reasoning method. The relationships among the four inferred conclusions are examined. The monotonicity and the approximation property for similarity-based approximate reasoning methods are defined. Then the monotonicity and the approximation property of Raha's similarity-based approximate reasoning method are studied.
