This study introduces a new fuzzy Program Evaluation and Review Technique (PERT) algorithm. It effectively identifies multiple critical paths in project networks with uncertain activity durations, overcoming limitations of existing fuzzy PERT methods.

Area of Science:

  • Operations Research
  • Project Management
  • Fuzzy Set Theory

Background:

  • Classical Program Evaluation and Review Technique (PERT) requires precise activity durations, which are often difficult to estimate accurately in real-world projects.
  • Existing fuzzy PERT methods, while addressing uncertainty, may fail to identify critical paths in fuzzy project networks.
  • This highlights a gap in managing projects with imprecise time estimations.

Purpose of the Study:

  • To propose a novel fuzzy PERT algorithm designed to find multiple critical paths in fuzzy project networks.
  • To address the limitation of existing fuzzy PERT methods that may not always identify a critical path.
  • To enhance project management capabilities for projects with uncertain activity durations.

Main Methods:

  • This approach aims to provide a more robust method for project scheduling under uncertainty.

    • Main Results:

    • The proposed fuzzy PERT algorithm successfully identifies multiple critical paths in fuzzy project networks.
    • It overcomes the drawback of existing fuzzy PERT methods that may fail to find a critical path.
    • Demonstrates improved capability in managing project schedules with uncertain activity durations.

    Conclusions:

    • The developed fuzzy PERT algorithm offers a significant advancement for project management in uncertain environments.
    • It provides a reliable method for identifying critical paths, even when activity durations are imprecisely defined.
    • This research contributes to more effective project control and decision-making with fuzzy data.
