TL;DR
This paper considers two ways of constructing global fuzzy preference structures: (i) aggregate the two-parameter single-criterion fuzzy outranking relations and then construct the global fuzzy preferences, and (ii) construct global fuzzier preference structures and then aggregate the single-Criterion fuzzy preference, indifference and incomparability relations.
Abstract
In this paper we deal with the construction of global fuzzy preference structures from two-parameter single-criterion fuzzy outranking relations proposed in [10] and which are based on the aggregation of outranking indices associated with α-cuts. We consider two ways of constructing global fuzzy preference structures: (i) aggregate the two-parameter single-criterion fuzzy outranking relations and then construct the global fuzzy preference structures and (ii) construct global fuzzy preference structures and then aggregate the single-criterion fuzzy preference, indifference and incomparability relations. We also investigate the case where these two ways of proceeding lead to the same results.

Important relationships are established between the basic properties of the components of a fuzzy preference structure without incomparability and the ( T, N )-Ferrers property of a binary fuzzy relation and it is shown that the fuzzy preference and fuzzy large preference relations share certain types of this Ferrers property.
