JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD B.Tech IV FLEXIBLE MANUFACTURING SYSTEMS Previous Question Paper (July/August - 2022 - R18)

In the current global market, the need for Flexible Manufacturing Systems (FMS) arises from the shift toward high-variety, low-volume production. Traditional mass production systems lack the agility to respond to rapid changes in consumer preferences and shorter product life cycles. FMS addresses these needs through several key factors:

• Product Customization: Consumers demand personalized products, requiring manufacturers to switch between different product designs quickly without significant downtime.
• Reduced Lead Times: FMS minimizes setup times and work-in-progress inventory, allowing companies to deliver products faster to the market.
• Economic Efficiency: By automating small-batch production, FMS bridges the gap between the high efficiency of dedicated transfer lines and the high flexibility of manual job shops.
• Competitive Advantage: The ability to respond rapidly to market fluctuations and introduce new products quickly ensures survival in highly volatile competitive environments.

A Flexible Manufacturing System is characterized by its ability to process a variety of part styles simultaneously and adapt to changes in production schedules. The fundamental characteristics include:

• Machine Flexibility: The capability to process different part types and adapt to changes in the sequence of operations.
• Routing Flexibility: The ability to use multiple machines to perform the same operation on a part, ensuring production continues even if one machine fails.
• Automated Material Handling: Integration of robots, conveyors, or automated guided vehicles (AGVs) to move parts between workstations without manual intervention.
• Centralized Computer Control: A hierarchical control system that manages machine tools, material handling, and scheduling to ensure real-time coordination.
• Variable Production Capacity: The system can be scaled or reconfigured to handle changes in production volume or product mix efficiently.
