Manufacturing has taken a new form post the introduction of Flexible Manufacturing System (FMS). Looking at it objectively, FMS goes beyond automation. It’s a core shift in the approach that represents flexibility and efficiency in manufacturing.
This article will equip you to:
What is a Flexible Manufacturing System?
A flexible manufacturing system or FMS is an integrated, computer-controlled manufacturing configuration that holds a mix of efficiency of automation with the adaptability of custom production. This ensures that manufacturing processes adapt quickly to product changes with minimal intervention, all while maintaining Six Sigma quality levels.
The concept of FMS emerged in the late 1960s, but I’ve observed its evolution from basic automated cells to today’s AI-enhanced smart manufacturing systems.
FMS installations can help companies achieve:
Key Operational Aspects
Several critical operational aspects distinguish FMS from traditional manufacturing systems:

Flexible Manufacturing System (FMS) in Today’s Context
Successful FMS implementations typically deliver:
The key to understanding FMS lies in recognizing it’s not just about automation – it’s about creating an intelligent, adaptive manufacturing environment.
Components of a Flexible Manufacturing System: A Master Black Belt’s Perspective
Understanding the core components of a flexible manufacturing system is crucial for successful deployment. These systems are far more than just automated machinery – they’re sophisticated networks of integrated components working in perfect synchronization.
A flexible manufacturing system consists of four primary components that I’ve seen revolutionize production floors across the globe.
Computer Numerical Control (CNC) Machines
Modern CNC machines form the backbone of any FMS. These programmable machines can perform multiple operations without manual intervention.
Material Handling Systems within a Flexible Manufacturing System
The automated material handling systems include:
Automated Storage and Retrieval Systems (AS/RS)
These systems manage:
Central Control System
The central control system is what I often call the “brain” of the FMS. Based on my statistical analysis of numerous implementations, this component typically includes:
The key to success lies in seamless integration of these components. I’ve found that the most effective FMS installations achieve this through:
When properly implemented, these components work together to create a manufacturing system that can adapt to changing production requirements while maintaining consistent quality levels.
Types of Flexible Manufacturing Systems
Each type offers distinct advantages, and selecting the right configuration can significantly impact your operational success.
Single Machine Cell
The single-machine cell represents the fundamental building block of flexible manufacturing. I’ve found this configuration particularly effective for small-scale, high-precision operations. It excels in environments where product variety is moderate but quality requirements are stringent.
Flexible Manufacturing Cell (FMC)
Moving up in complexity, the flexible manufacturing cell combines multiple processing stations with integrated material handling. FMCs differ from single cells by offering greater processing capabilities and improved workflow management. They’re ideal for medium-sized operations requiring significant production flexibility.
Flexible Manufacturing Group (FMG)
Flexible manufacturing groups essentially network multiple FMCs together. The key distinction between FMGs and simpler cells lies in their enhanced coordination capabilities.
Flexible Manufacturing Line (FML)
The flexible manufacturing line configuration arranges processing stations in a linear sequence while maintaining routing flexibility. The linear arrangement provides excellent throughput for high-volume operations while maintaining the ability to handle product variants.
Flexible Transfer Line (FTL)
The most sophisticated configuration is the flexible transfer line. FTLs have proven exceptional for high-volume production with moderate variety requirements. These systems combine the speed of traditional transfer lines with flexible processing capabilities.
Selection Considerations of a Flexible Manufacturing System
Selecting the appropriate Flexible Manufacturing System (FMS) type depends on several critical factors. When consulting with clients, I evaluate:
For example, when helping a small electronics manufacturer choose between an FMC and FMG, our analysis showed that an FMC would provide optimal ROI given their specific parameters.
How a Flexible Manufacturing System Work: An Expert’s Analysis
The operational flow of a flexible manufacturing system begins with the computer control system, which I often describe as the system’s central nervous system. This control system manages everything from production scheduling to quality control parameters.
Material handling within an FMS follows what I call the “intelligent flow principle”. The system automatically routes raw materials, work-in-progress, and finished products through the production process using automated guided vehicles (AGVs), conveyors, and robotic handling systems.
This automation eliminates the inefficiencies I frequently encountered in traditional manufacturing environments.
Process integration ensures that all manufacturing operations work in perfect synchronization.
The system’s ability to adapt to changes in real-time is what truly sets it apart. Effective FMS installations can typically:
The feedback loop is another crucial element , I always emphasize in my work. Modern FMS installations collect and analyze data from every operation, creating what I call a “self-learning manufacturing environment”.
Based on my experience leading international projects, I can say that successful FMS operation requires a delicate balance of automation and human oversight.
While the system handles routine operations autonomously, skilled operators and engineers play crucial roles in optimization and strategic decision-making.
Through careful integration of these operational elements, a flexible manufacturing system creates what I call a “responsive production ecosystem”. This ecosystem can adapt to changing production requirements while maintaining consistent quality levels – a capability that’s becoming increasingly crucial in today’s dynamic manufacturing environment.
