ABSTRACT:
In a fuzzy inference operation method according to the present invention, the condition part membership function is referred to according to a singleton input variable so as to determine the condition part membership value and then the determined condition part membership value is judged whether it is the minimum value for a membership value. If so, the minimum value is used as the desired membership value and the system omits the MIN and MAX value operations for the applicable condition part membership value and jumps to the MIN-MAX operation under the next rule. Besides, a fuzzy inference operation device comprises a condition part membership value judgment means to judge whether the condition part membership value determined by the condition part membership value determining means is the minimum membership value or not and a control means which omits the operations by the MIN value operation means and the MAX value operation means for the applicable condition part membership value if it is judged to be the minimum membership value.
