Rotating Shift Pattern
Rotating Shift Pattern problems involve employees rotating through different shifts on a regular schedule. You need to calculate how many days until an employee returns to the same shift pattern.
What You'll Learn
Introduction to Rotating Shift Pattern
Rotating Shift Pattern problems involve employees rotating through different shifts on a regular schedule. You need to calculate how many days until an employee returns to the same shift pattern.
Prerequisites
How to Solve Rotating Shift Pattern Problems
Step 1: Identify number of employees (E) and number of shifts (S)
Step 2: Determine rotation frequency (R days per rotation)
Step 3: Cycle length = E × R (for simple rotation)
Step 4: If shifts rotate independently, cycle = LCM of periods
Step 5: Answer with number of days in cycle
Example Problem
Example: 4 employees, shifts rotate every 5 days. How many days until same employee returns to same shift pattern? Solution: Step 1: E = 4, R = 5 Step 2: Cycle = E × R = 4 × 5 = 20 days Answer: 20 days
Pro Tips & Tricks
- Cycle length = E × R when each employee rotates through all shifts
- If shifts rotate independently, use LCM
- After cycle, both employee and shift pattern align
- For multiple rotation speeds, use LCM of individual periods
