Approximate reasoning apparatus

An apparatus for outputting a clarity for an approximate reasoning apparatus, comprising:

• a knowledge memory for storing relationships between factors and conclusions expressed as membership functions;
• a knowledge synthesizing unit for combining said membership functions which express identical factors and conclusions as synthesized membership functions;
• a static information quantity computing unit which determines a static information quantity of each factor with respect to said synthesized membership functions used in said approximate reasoning, said static information quantity representing the capability of a membership function of a factor to identify a conclusion;
• a clarity computing unit which determines a clarity value for each factor for every conclusion using the determined static information quantities;
• a clarity memory for storing said clarity values of each factor for every conclusion;
• a clarity adding means for determining a clarity with regard to results of reasoning using the clarity values stored in said clarity memory for each factor for which data has actually been inputted;
• and
• a clarity display unit for displaying said clarity with regard to results of reasoning obtained from said clarity adding means.
