Study Notes
Flow Shop Layout
- A synchronous production line with multiple machines and workstations integrated into one system, connected by conveyor systems
- Operates like a single machine, producing one unit per cycle
- Advantages: • Very high production rates • Reduced labor cost • Reduced work-in-process • Reduced transportation distance and time
Transfer Lines
- A synchronized production line with multiple machines and workstations integrated into one system
- Operates like a single machine, producing one unit per cycle
- Advantages: • Very high production rates • Reduced labor cost • Reduced work-in-process • Reduced transportation distance and time
Flexible Manufacturing Systems (FMS)
- Allows adaptability when faced with production changes
- Consists of several machine tools, parts, and tool handling devices
- Flexibility: management similar to job shop
Cellular Manufacturing Systems
- Enables adaptability when faced with production changes
- Consists of several machine tools, parts, and tool handling devices
- Flexibility: management similar to job shop
Little's Law
- Average time = average number of customers / average arrival rate
- Applies in steady-state systems where the mean arrival rate is constant
- Example: Willow Run Factory, producing 453 airplanes in 468 hours
Waiting
- Goal: minimize waiting time to optimize profit
- Waiting causes: • Under-utilization • Idle workforce • Inventory buildup
Manufacturing System Types
-
- Job shop: wide variety of skills, high-skilled workers, produces small batches of products or custom products
-
- Flow shop: fixed linear structure, grouped by process order, low flexibility, high volume
-
- Transfer lines: synchronized production line with multiple machines, high production rates
-
- Flexible Manufacturing Systems (FMS): adapts to production changes, similar to job shop
-
- Cellular Manufacturing: adapts to production changes, similar to job shop
Machine Line
- Unreliable machine: machine failure affects production
- 1 machine line: deterministic systems, can be modeled using D/D/1 queue
- 1 machine line: stochastic systems, can be modeled using M/M/1 queue
- Multiple machines and inventory: complex systems with multiple variables
Challenges in Manufacturing Systems
- Industry-related challenges: • External factors affecting production
- Inherent challenges: • Machine reliability • Operator reliability • Material availability • Process variability
