Usual criterion

H ( d j ) = { 0 if d j = 0 1 if d j 0

Quasi criterion

H ( d j ) = { 0 if d j q i 1 if d j q i

Criteria with linear preference and no indifference area

H ( d j ) = { d j p j if d j p i 1 if d j p i

Level criterion

H ( d j ) = { 0 , if d j p j 0.5 ; q j < d j < p j 1 ; d j p j

Croterion with linear preference and indifference area

H ( d j ) = { 0 , if d j q j d j q j p j q i ; if q j d j p j 1 , if d j > p i ,

Gaussian criteria

H ( d j ) = 1 e d j 2 2 s j 2

The value of is the distance between the origin and the point of inflexion of the considered preference function.
