garment-smv-calculator
SMV (Standard Minute Value) calculator for the garment industry. Formula: SMV = Basic Time × (1 + Allowance%). Built and used in production by Scan ERP.
Install
pip install garment-smv-calculator
Usage
from garment_smv_calculator import calculate_smv, calculate_hourly_capacity
# Calculate SMV for a sewing operation
smv = calculate_smv(
observed_time_seconds=18, # From stopwatch observation
performance_rating=1.05, # Westinghouse: skilled at 105%
allowance_percent=0.30, # 30% (personal + fatigue + delay)
)
print(f"SMV: {smv:.2f} minutes per piece")
# → SMV: 0.41 minutes per piece
# Calculate operator hourly capacity
capacity = calculate_hourly_capacity(smv_minutes=smv, efficiency_percent=85)
print(f"Hourly capacity at 85% efficiency: {capacity} pieces")
Background
SMV is the foundation metric for piece-rate wage calculation in CMT garment factories. Without accurate SMV, every downstream calculation produces wrong numbers.
