ELECTRE TRI is a method designed to sort alternatives evaluated on several criteria into ordered categories. The original method uses limiting profiles. A recently introduced variant uses central profiles. We study the relations between these two variants. We do so by investigating if an ordered partition obtained with one variant can also be obtained by the other variant, after a suitable redefinition of the profiles. We also investigate the transposition operation that was introduced by the authors of the variant using central profiles. We study the consequences of applying this operation to the variant using limiting profiles. This leads us to propose an alternative variant of ELECTRE TRI that uses limiting profiles. We show that this alternative variant may have some advantages over the original one.
