An effective method for large scale project planning with multiple fuzzy activity times

Abstract

Presents a method for solving a project planning problem in which the opinions of experts greatly disagree in terms of each activity processing time. Here, the goal is to determine the fuzzy project completion time and the degree of criticality for each path in a project network. Triangular fuzzy numbers (TFNs) are used to represent activity times of experts. Pessimistic object plan is introduced with major TFNs and an optimistic project plan with minor TFNs. The approach is illustrated by using a combination of the existing composite and comparison methods to determine the fuzzy project completion time and the degree of criticality for each path.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
