The purpose of this pa,per is to present the performance evaluation of computer system with failure based on fuzzy set theory. The performance evaluation of on-line computer system with failure is fuzzified. We represent the performance measures of the on-line computer system by modeling occurrences of failed computer equipment units based on fuzzy set theory. We are forced to employ subjective possibilities or probabilities when there is no information about a model or some paramneters of a model are vague. The information may be obtained subjectively from experts or very little data. We present the fuzzification model and the performance evaluation of on-line computer system with failure based on fuzy set theory. Also, it is shown that this performance evaluation is more flexible and realistic than crisp performance evaluation of conventional method in some numerical examples.
