Fuzzy Time Scheduling
Fuzzy Time Scheduling problems involve tasks with uncertain durations given as three estimates: optimistic (a), most likely (m), and pessimistic (b). The expected duration is calculated using the PERT formula: (a + 4m + b)/6.

Introduction to Fuzzy Time Scheduling
Fuzzy Time Scheduling problems involve tasks with uncertain durations given as three estimates: optimistic (a), most likely (m), and pessimistic (b). The expected duration is calculated using the PERT formula: (a + 4m + b)/6.
Prerequisites
How to Solve Fuzzy Time Scheduling Problems
Step 1: For each task, note optimistic (O), most likely (M), pessimistic (P) durations
Step 2: Calculate expected duration = (O + 4M + P) / 6
Step 3: Sum expected durations for total project expected time
Step 4: Answer with expected total duration
Example Problem
Example: Task: O=2, M=4, P=6 days. Expected duration? Solution: Step 1: O=2, M=4, P=6 Step 2: Expected = (2 + 4×4 + 6)/6 = (2 + 16 + 6)/6 = 24/6 = 4 days Answer: 4 days
Pro Tips & Tricks
- PERT = Program Evaluation and Review Technique
- Formula: (O + 4M + P)/6
- Variance = ((P - O)/6)² (for advanced problems)
- More likely values (M) weighted 4 times
- Result is a weighted average
