FIELD: information technologies.
SUBSTANCE: method to support decision-making based on instances includes a stage of calculation of remoteness from likeness between the input case of requesting and the set of instances for extraction of similar cases, using the set of standard criteria and their weights for assessment of likeness. Then, in accordance with the method, a user is provided with similar instances and a set of standard criteria and weights. And also an input is received from the user, including a variable weight for one of the set of standard criteria and/or one new criterion in addition to the set of standard criteria. Besides, the calculation of remoteness from likeness is varied with a new set of criteria and weights for extraction of instances similar from the point of view of the user. At the same time a new set of criteria and weights is generated on the basis of clustering on the basis of likeness for variation of calculation of the remoteness from likeness by means of start-up of a genetic learning logic.
EFFECT: creation of a basis system of input estimates of likeness for adaptation of actual value of likeness to similar users with another experience or other opinion.
