Historical Context
The concept of Flexible Manufacturing Systems (FMS) emerged in the late 1960s and early 1970s as manufacturers sought ways to adapt to rapid changes in consumer demand. The development of computer-controlled machinery and robotics facilitated the evolution of FMS, making it a cornerstone of modern manufacturing practices.
Types/Categories
FMS can be categorized based on different criteria:
- Dedicated FMS: Designed for manufacturing a limited range of similar products.
- Random FMS: Capable of handling a wide variety of products without extensive reconfiguration.
- Modular FMS: Systems that can be expanded or reconfigured with additional modules to handle different products.
Key Components
- Workstations: Machines or robots that perform specific tasks such as cutting, welding, or assembly.
- Material Handling Systems: Automated conveyance systems including AGVs (Automated Guided Vehicles) and robotic arms.
- Computer Control System: The central nervous system of FMS that schedules tasks, controls machinery, and monitors production.
- Storage Systems: Automated storage and retrieval systems (AS/RS) that manage materials and work-in-progress.
Key Events in FMS Development
- 1970s: Introduction of CNC (Computer Numerical Control) machines.
- 1980s: Integration of CAD/CAM (Computer-Aided Design and Computer-Aided Manufacturing).
- 2000s: The rise of Industry 4.0 incorporating IoT (Internet of Things) for smarter manufacturing.
Detailed Explanation
FMS represents a paradigm shift from traditional manufacturing methods by emphasizing flexibility, efficiency, and automation. It allows for rapid changes in production lines without significant downtime, enabling businesses to respond quickly to market demands.
Advantages of FMS
- Cost Reduction: Reduced labor costs and minimized waste.
- Increased Flexibility: Ability to switch between product lines without extensive retooling.
- Higher Productivity: Continuous operation and reduced setup times.
Disadvantages of FMS
- High Initial Investment: Significant upfront costs for machinery and setup.
- Complexity: Requires sophisticated control systems and skilled operators.

Importance and Applicability
FMS is crucial in industries such as automotive, electronics, and aerospace where demand variability and customization are high. It provides the ability to mass-produce different product lines efficiently and economically.
Examples
- Automotive Industry: Flexible manufacturing systems are used to produce various car models on a single assembly line.
- Electronics: Manufacturing of different types of smartphones or other electronic devices with minimal reconfiguration.
Considerations
When implementing an FMS, companies must consider the following:
- Scalability: The ability to expand or reconfigure the system for future needs.
- Integration: Seamless integration with existing systems and processes.
- Training: Ensuring staff are adequately trained to operate and maintain the system.
Related Terms
- CNC (Computer Numerical Control): Automation of machine tools through computer programming.
- Industry 4.0: The current trend of automation and data exchange in manufacturing technologies.
- Lean Manufacturing: A systematic method for minimizing waste within a manufacturing system without sacrificing productivity.
Comparisons
- FMS vs Traditional Manufacturing: Traditional manufacturing is rigid and efficient for large batches of a single product, whereas FMS offers flexibility for producing multiple products.
- FMS vs Lean Manufacturing: While both aim to enhance efficiency, FMS focuses on flexibility and automation, whereas Lean Manufacturing emphasizes waste reduction and continuous improvement.
Interesting Facts
- The concept of flexible manufacturing systems is closely related to the idea of “mass customization,” which allows for tailored products at mass production costs.
- FMS was a precursor to the development of “smart factories” under the Industry 4.0 paradigm.
