An Introduction to Conflicting Bifuzzy Sets Theory

Zamali Tarmudi, Mohd Lazim Abdullah, Abu Osman Md Tap


In the usual cognitive cycle, the evaluation process only takes into account the positive aspects without considering even a single negative aspect. In these cases, the evaluation process is not precise and does not represent the actual situation. However, by this new proposed socalled "conflicting bifuzzy sets" concept, both positive and negative aspects will be considered simultaneously in the judgement process. A definition of the "conflicting bifuzzy set" concept is given, the latter being a generalization of the intuitionistic fuzzy set concept. To clarify the theoretical above concepts, the practical examples of evaluation approach is provided and the result shows it was well-suited with reality and comprehensible in concept. The proposed concept indeed is a generalized method, which can be applied to many other practical problems.
