Abstract: A new method, named as Mehar's method is proposed to solve fuzzy critical path problems. To show the advantages of the Mehar's method over an existing method the results of a fuzzy critical path problem, obtained by using the existing and Mehar's method, are compared. Also, it is shown that although the results, obtained by using the existing and Mehar's method, are mathematically correct but the obtained and the existing results have no physical meaning. To overcome this shortcoming a new subtraction operation, named as Mehar's subtraction, is introduced and the Mehar's method is further modified with Mehar's subtraction.
