L6: Capacity Management

1. Initial Cases

   • The Penang Mutiara
   • Panettone : Seasonal Demand

2. Difing Capacity

3. Capacity Management Challenge

4. Korea's Unused Airports

5. Resource Yield

   • Capacity Leackage
   • Utilisation
   • Efficiency
   • Capacity Varies
     • Product/service mix chnages
     • Level of output (sustain)
     • Specification of Output
   • OEE
     • NB - Fig 8.3
     • 3 sources of capcity loss
       • Availability Losses
       • Speed Losses
       • Quality Losses

6. Long-term Capacity Management

   • Cap Lead & Lag
     • Graphs

7. S. Cause Demand Fluct/s

   • 2 Cases

8. Capacity Adjustment

   • Matching demand & capacity
   • Fig 6.10
   • Demand
     • Predictable (variation)
     • Unpredictable (variation)

9. Snow (retailers)

10. Medium-term Planning

    • Level Capacity
    • Chase Capacity
    • Manage Demand
    • Mixed Planning
    • Fig 6.12.1

11. Techniques to Increase Short-run Capacity

    • Increase Resources
    • Improve Resource Utilisation
    • Modify Output
    • Do not meet Demand
    • Lovelock & Lovelock
      • Managing Service Operations

12. Queue Management

    • Infinite queue
    • Impact of demand and cap variation
    • Impact of prioritisation
