Fuzzy set computational processes in risk analysis

An article by R. Kangari and L.S. Riggs (see ibid., vol.36, no.2, p.126-31, 1989), which dealt with the use of fuzzy sets in construction risk analysis, contains a number of errors and inconsistencies, most of which appear in examples given to clarify the concepts involved in computations related to fuzzy sets. The errors and inconsistencies are identified, and the computational results are clarified by providing the correct results for enough computations to ensure an understanding of the processes involved.<
