FINDING CRITICAL PATHS IN A FUZZY PROJECT NETWORK WITH OCTAGONAL FUZZY NUMBERS

Abstract

Production-based calculations of activity duration are possible, but sometimes the results of this approach are estimations that are too general and imprecise. To get around this problem, we can use fuzzy numbers to define the activity periods. As a result, the activity durations in this paper are represented by octagonal fuzzy numbers (a, b, c, d, e, f, g, h).

A clear numerical example is provided to showcase the superiority of the proposed algorithm and method.
