• Adaptive fusion allows the use of renormalized conjunctive fusion when sources agree, and disjunctive fusion when they are in conflict.
  
  
• The assumption according to which the two sources are reliable is privileged. Renormalized conjunctive fusion makes it possible to give more importance to the area for which the two sources agree. Nevertheless disjunctive fusion is introduced to take the conflict between the sources into account, but restricted to the degree of conflict.
  
  
• In the presence of conflict between sources, progressive transition occurs from conjunctive fusion to disjunctive fusion.

This adaptive fusion was defined for the fusion of two sources. It is obviously possible to use it to fuse a greater number of sources. However, when the number of sources increases, it becomes generally difficult to maintain the assumption of reliable sources. Indeed it is difficult to obtain a common opinion with all the sources. There is often a conflict between several sources. Some difficulties occur because conjunctive fusion seeks to express an opinion for which there is unanimity of the sources. Adaptive fusion reacts to conflict by intensive use of disjunctive fusion, even if a majority of sources agree over a common interval. This is the main limitation of adaptive fusion: an incapacity to correctly manage fusion of a great number of sources.

In addition, instability is found around either a tiny or an empty intersection of possibility distributions, expressed during the description of the renormalized conjunctive operator. But this instability is less awkward because of the concurrent use of disjunctive fusion to manage the strong conflict.

Lastly, it is regrettable that computation of the degree of consensus h between all the sources makes this operator not associative.
