Generic Method of Taking Account of Several Parameters in a Value Judgement Function

摘要

The method of the invention is a method of taking account of several parameters in a value judgment function, according to which the judgment function depends mainly on a main parameter and in a secondary manner on at least one secondary parameter, and it is characterized by the fact that the model is constructed by asking the expert for the main parameter and the list of secondary parameters, by asking the expert to specify the mono-dimensional function which, for determined values of the secondary parameters, associates the value of the judgment with the main parameter, and by asking the expert how the mono-dimensional judgment function is modified as a function of the determined values of the secondary parameters, that the user provides the values of the main parameter and of the secondary parameters corresponding to at least one option to be evaluated, that the value of the judgment is calculated for each option by determining the mono-dimensional judgment function dependent on the main parameter on the basis of the values of the secondary parameters and by applying this function to the value of the main parameter, and that a list of values of this judgment function for each option is generated for the user.
