Comments on 'An object-parameter approach to predicting unknown data in incomplete fuzzy soft sets' [Appl. Math. Modell. 37 (2013) 4139-4146]

摘要

In this short paper, we point out the object-parameter method proposed in is not always effective under some incomplete circumstances, sometimes, the predicted data obtained by this method are greater than one, this result does not satisfy what is required in the definition of membership degree of fuzzy sets.
