Introduction to Shift Rotation Schedule
Shift Rotation Schedule problems involve assigning employees to different work shifts (morning, evening, night) across multiple days with constraints like no same shift on consecutive days, fixed assignments, and exclusions.
Prerequisites
How to Solve Shift Rotation Schedule Problems
Step 1: Create a table with days as rows and shifts as columns
Step 2: Place fixed assignments (e.g., 'Alice works Morning on Monday')
Step 3: Apply exclusion constraints (e.g., 'Bob cannot work Night shift')
Step 4: Apply rotation constraints (e.g., 'No same shift two days in a row')
Step 5: Fill remaining cells using elimination
Step 6: Ensure each shift has one employee per day
Step 7: Answer the specific question
Example Problem
Example: Employees: Alice, Bob, Charlie, Diana. Shifts: Morning, Evening, Night. Constraints: Alice works Morning Monday, Charlie works Evening Tuesday, Bob cannot work Night. Who works Evening Wednesday? Solution: Step 1: Table: Mon: M(Alice), E(?), N(?); Tue: M(?), E(Charlie), N(?); Wed: M(?), E(?), N(?) Step 2: Bob no Night → Bob can only be M or E Step 3: Monday Evening: can be Bob or Diana; Monday Night: Diana (if Bob E) or Bob (if Diana E) Step 4: Tuesday: M=Bob or Diana, N=Bob or Diana (but Bob no N → N=Diana, M=Bob) Step 5: Wednesday: Need to avoid same shift as previous day Step 6: Charlie was E Tue → cannot be E Wed → Charlie M or N Step 7: Alice was M Mon → can be E Wed Step 8: Fill systematically → Evening Wed = Alice Answer: Alice
Pro Tips & Tricks
- Use grid with days horizontally, shifts vertically, or vice versa
- Mark fixed assignments clearly
- List available employees for each slot
- Use 'cannot' constraints to eliminate options
- Rotation: employee cannot have same shift on consecutive days
- Each employee works exactly one shift per day
