What Is Throughput?
- Throughput is the number of units produced in a given period of time.
- It is commonly tracked as pieces per hour or pieces per day.
Why Throughput Is Important
- Measures production speed.
- Supports efficiency improvement initiatives.
- Helps set practical production targets.
- Supports lean manufacturing by focusing on flow.
Throughput Formula
- Throughput = Total Output / Total Time
Understanding the Formula
- Output = number of garments produced.
- Time = total production time.
Step-by-Step Throughput Calculation
- Step 1: Measure output (example: 1200 pcs).
- Step 2: Measure time (example: 8 hours).
- Step 3: Apply formula: 1200 / 8 = 150 pcs/hour.
Throughput Calculation Example
- Output = 2000 pcs, Time = 10 hours.
- Throughput = 2000 / 10 = 200 pcs/hour.
- Final throughput = 200 pieces per hour.
Throughput vs Productivity
- Throughput focuses on output per time.
- Productivity often focuses on output per resource (worker/machine).
Throughput vs Cycle Time
- Throughput is output rate.
- Cycle time is time per unit.
- Higher throughput generally means lower cycle time.
Throughput in Lean Manufacturing
- Throughput is central in lean and Theory of Constraints approaches.
- Main goal: increase throughput by removing waste and bottlenecks.
Factors Affecting Throughput
- Machine efficiency and downtime.
- Operator skill and method consistency.
- Bottlenecks in critical operations.
- Line balancing quality.
Common Problems Reducing Throughput
- Bottlenecks.
- Machine downtime.
- Poor workflow.
- Inefficient layout.
How to Improve Throughput
- Remove bottlenecks in constraint operations.
- Improve line balancing.
- Raise efficiency through training and maintenance.
- Use automation where suitable.
Practical Industrial Use
- Monitor production speed.
- Plan output and delivery.
- Optimize workflow.
- Support continuous improvement.
Throughput and Profit
- Higher throughput can lower cost per unit and increase profitability when quality is controlled.
