Abstract: This paper presents a modification of the original method in which the concept of fuzzy set theory is applied in the calculation of the PCR. Fuzzy numbers are introduced to represent those linguistic terms used in assessing distress severity and extent conditions. Fuzzy arithmetic is then used to manipulate arithmetic operations on fuzzy numbers. finally, the fuzzy numbers are defuzzified using a ranking method so a comparison among them can be made. The results show that the proposed method may be used as a more realistic approach for computing the PCR.
