Modification of the Ahp Method Based on Interval Valued Rough Numbers
نویسندگان
چکیده
This paper presents a new approach for the treatment of uncertainty which is based on interval rough numbers (IRN). IRN based approach uses only internal knowledge i.e. operational data without relying on assumption models. In other words, instead of various additional/external parameters, IRN uses only the structure of the existing data. Based on the IRN there has been developed a novel IRAHP model (Interval Rough Analytic Hierarchy Process). The IR-AHP model has been tested on the case evaluation of outsourcing transport service. Modified IR-AHP method was used to determine the weights of coefficients of criteria in group decision-making process. The results of IR-AHP model were compared with the results given by the traditional AHP method and fuzzy AHP approach.

Ranking triangular interval-valued fuzzy numbers based on the relative preference relation
In this paper, we first use a fuzzy preference relation with a membership function representing preference degree forcomparing two interval-valued fuzzy numbers and then utilize a relative preference relation improved from the fuzzypreference relation to rank a set of interval-valued fuzzy numbers. Since the fuzzy preference relation is a total orderingrelation that satisfies reciprocal and tra...

It is firstly proved that the multi-input-single-output (MISO) fuzzy systems based on interval-valued $R$- and $S$-implications can approximate any continuous function defined on a compact set to arbitrary accuracy. A formula to compute the lower upper bounds on the number of interval-valued fuzzy sets needed to achieve a pre-specified approximation accuracy for an arbitrary multivariate con...
