SUMMARY:

Decision making is a process present in the routine of people and organizations around the world. Whether due to the number of agents involved or the conflicting character of the choice criteria, in many situations this process can be complex and there may not be a trivial solution. In this context, the so-called Multicriteria Decision Support (AMD) stands out, a decision support methodology, composed of several methods in different conceptions. Among the main concepts, there is the so-called Ideal Solution concept, with classic methods such as TOPSIS, VIKOR, and more recent ones such as the Reference Ideal Method (RIM). Unlike the classic methods, the use of the concept of Ideal of Reference, the RIM method allows to solve problems where the ideal in each criterion is not necessarily extreme values to the interval of each criterion. The RIM method, as well as the classic methods, was proposed to be applied in situations described in clear (real) values. However, in many decision problems, information is inaccurate, vague, incomplete and inconsistent. In order to solve these situations, these methods are extended to other types of sets, which allow representing this information, such as the Fuzzy Set, Intuitionist Fuzzy Set and the Neutrosophical Set. Considered a generalization of the others, the Neutrosophical Set can adequately represent incomplete, vague and inconsistent information, that is, it represents the decision-making process more completely than the others. With a Systematic Literature Review, it was found that there is no MCDM method in the literature using the concept of Ideal of Reference to solve decision problems in the neutral environment. In this sense, this work aimed to propose an extension of the RIM method to the neutral environment, allowing to properly represent multicriteria decision making problems with inaccurate, incomplete, vague and inconsistent data. The new method was proposed with two different normalization functions. The first considering distance to the average of the extremes of the Ideal of Reference and the second considering the distance to the extremes of the Ideal of Reference. In order to demonstrate the applicability of the method, an illustrative example in the global supplier selection literature was used. After applying the method, it was found that for both normalization functions, the ordering of the alternatives was the same.
