SMV Formula:
| From: | To: |
SMV (Standard Minute Value) is a key performance metric in the garment industry that represents the standard time required to complete a specific operation or garment. It's used for production planning, cost calculation, and efficiency measurement.
The calculator uses the SMV formula:
Where:
Explanation: The basic time represents the pure work time, while allowances account for various factors that affect worker performance and comfort.
Details: Accurate SMV calculation is crucial for production planning, cost estimation, line balancing, and performance measurement in garment manufacturing. It helps in setting realistic production targets and ensuring fair workload distribution.
Tips: Enter the basic time and allowance in minutes. Both values must be non-negative numbers. The calculator will provide the total SMV in minutes.
Q1: What is the typical range for allowances in SMV calculation?
A: Allowances typically range from 10% to 20% of the basic time, depending on work conditions and company policies.
Q2: How is basic time determined?
A: Basic time is determined through time study observations, where trained observers measure the time taken by skilled workers to complete specific operations.
Q3: Why is SMV important in garment production?
A: SMV helps in capacity planning, cost calculation, efficiency measurement, and setting production targets for garment manufacturing.
Q4: Can SMV vary for the same operation?
A: Yes, SMV can vary based on fabric type, machine efficiency, operator skill level, and work methods used.
Q5: How often should SMV be updated?
A: SMV should be reviewed and updated regularly, especially when there are changes in methods, machinery, or materials to maintain accuracy.
