Abstract

The invention concerns a method and an apparatus for providing an individually sorted sequence of elements. An apparatus according to the invention of that kind comprises: a storage device wherein there is stored a plurality of elements and in relation to each element a description set in which there is stored in relation to the respective element with regard to each of at least three criteria a conformity value by which the conformity of the respective element with the criterion is assessed, a user interface which makes it possible for a user to select at least two criteria from a plurality of criteria and to select a weighting factor between the two criteria, which determines which of the two criteria is to be taken into account preferredly in relation to the other criterion, and a sorting device which constructs a sequence of elements and is adapted to arrange a first element before a second element when the conformity value for the first criterion which the user has selected as preferred is higher in the description set of the first element than the conformity value for the first criterion in the description set of the second element, and/or the conformity value for the second criterion which the user has selected as less preferred is lower in the description set of the first element than the conformity value for the second criterion in the description set of the second element.
