garment wastage calculation
Garment Wastage Calculation
This garments and industrial engineering guide is built for IE teams, line supervisors, and production planners.
Bangladesh-focused guide with practical calculation workflow.
Step-by-Step Explanation
- Collect operation-time, manpower, output, and working-hour data accurately.
- Apply standard IE formula in the same method every day for consistent tracking.
- Use calculated values for target, balancing, and bottleneck decisions.
Formula
- Efficiency % = (Day Production × SMV) / (Manpower × Working Hour × 60) × 100
- Target/Day = (Manpower × Working Hour × 60 × Efficiency %) / SMV
Example Calculation
- If production is 2,400, SMV is 1.0, manpower is 50, and hours are 8, efficiency is 100%.
- Use the target/day formula to set realistic production commitment.
FAQ
- Which value impacts efficiency most? SMV accuracy and manpower deployment both matter.
- Should formulas be recalculated by style? Yes, each style should be measured separately.
