Factory Physics Notes
Topic 1: The Principles of Factory Physics
- Factory Physics provides a scientific framework for manufacturing systems.
- It focuses on variability, buffers, and flow.
Topic 2: Variability in Production Systems
- Sources of variability: demand, process, supply chain.
- Variability impacts cycle time, WIP, and throughput.
Topic 3: Little's Law
-L=λ*W
- Work-in-process (WIP) = Throughput rate * Cycle time.
Topic 4: Push vs Pull Production
- Push: schedule-driven, risk of overproduction.
- Pull: demand-driven, often linked with Kanban systems.
Topic 5: Practical Applications
- Improve predictability by controlling variability.
- Balance utilization and cycle time to optimize throughput.
