What Is Pitch Time?
- Pitch time is the time interval required to produce one unit or batch in a production line.
- It indicates how frequently finished output should come from the line.
Why Pitch Time Is Important
- Supports smooth production flow.
- Improves line balancing and workload distribution.
- Helps identify bottlenecks and delays.
- Enhances overall line efficiency.
Pitch Time Formula
- Pitch Time = SMV × Number of Operators
Alternative Concept (Output-Based)
- Pitch Time = Available Time / Target Output
Understanding the Formula
- SMV = standard minute value per garment.
- Operators = total workers in line.
- Available Time = total working minutes.
Step-by-Step Pitch Time Calculation
- Step 1: Determine SMV (example: 0.5 minutes).
- Step 2: Count operators (example: 20 workers).
- Step 3: Apply formula: Pitch Time = 0.5 × 20 = 10 minutes.
Pitch Time Calculation Example
- SMV = 0.6, Operators = 25.
- Pitch Time = 0.6 × 25 = 15 minutes.
- Final pitch time = 15 minutes per batch/unit.
Pitch Time vs Cycle Time
- Pitch time: line-level time interval per unit output.
- Cycle time: workstation-level time for one operation.
- Pitch time is mainly used for line balancing; cycle time for process design.
Role of Pitch Time in Line Balancing
- Helps balance workload across operators.
- Reduces idle time and uneven flow.
- High pitch time can indicate slow production; very low pitch may overload workers.
Factors Affecting Pitch Time
- SMV accuracy.
- Number of operators.
- Production method quality.
- Line layout and movement losses.
Common Mistakes in Pitch Time Calculation
- Using incorrect SMV.
- Ignoring actual manpower.
- Not considering efficiency realities.
- Poor line balancing assumptions.
How to Improve Pitch Time
- Optimize line balancing and workload split.
- Reduce SMV via better methods/tools.
- Improve operator skill through training.
- Use automation to reduce manual delays.
Practical Industrial Use
- Monitor production flow.
- Set output intervals.
- Improve efficiency.
- Identify bottlenecks quickly.
Pitch Time and Production Target
- Pitch time directly impacts hourly output, daily output, and line efficiency.
