Summary: Project network planning problem with fuzzy durations of operations has been investigated. Two approaches to criticality analysis of operations classified as a path criticality and a float criticality ones are distinguished. It has been ascertained that both methods do not provide an efficient solution of the fuzzy network planning problem to full extent. A generalized fuzzy critical path method based on aggregation of the path and the float ones has been proposed. Advantages of generalized criticality degree using are demonstrated by numerical experiments.
