Abstract :
This paper describes a new method that builds consonant possibility distributions from non-consonant intervals. Consonance is ensured by appropriate selection of overlapping intervals and assignment of weights derived by conventional frequency analysis. In the selection of intervals and calculation of weights for the corresponding interval, the underlying evidence is considered to point to a single interval. An example in the area of structural dynamics is provided to illustrate this new method
