ABSTRACT:
An input value sorter for calculating a conformity grade in a fuzzy inferential device has a comparator for sequentially receiving data indicative of a position of each of vertexes of a membership function defined as a polygon and receiving fact data. The comparator sequentially compares the fact data showing a determined value with the data indicative of the position of each of the vertexes. The input value sorter also has a device for specifying a side or vertex of the polygon belonging to the fact data on the basis of compared results of the comparator and an input order of the vertexes. A grade arithmetic unit has this input value sorter. In this grade arithmetic unit, the membership function can be suitably sorted by a simplified construction.
