SAM Formula:
| From: | To: |
SAM (Standard Allowed Minutes) is a key performance metric in the garment industry that represents the total time allowed to complete a specific operation or garment. It's the sum of basic time (the observed time for an operation) and allowance time (additional time for rest, fatigue, and other factors).
The calculator uses the SAM formula:
Where:
Explanation: The SAM calculation provides a standardized measurement of the time required to complete garment manufacturing operations, helping in production planning and efficiency analysis.
Details: Accurate SAM calculation is crucial for production planning, cost estimation, efficiency measurement, and workforce management in the garment industry. It helps manufacturers set realistic production targets and price their products appropriately.
Tips: Enter the basic time and allowance time in minutes. Both values must be non-negative numbers. The calculator will sum these values to provide the total SAM.
Q1: What is the difference between basic time and SAM?
A: Basic time is the observed time for an operation, while SAM includes additional allowances for various factors, making it the total standard time allowed for that operation.
Q2: How is allowance time determined?
A: Allowance time typically includes factors like personal needs, fatigue, machine delays, and other contingencies, usually calculated as a percentage of basic time.
Q3: Why is SAM important in garment manufacturing?
A: SAM helps in setting production targets, calculating efficiency, determining manpower requirements, and pricing garments accurately.
Q4: Can SAM vary for the same operation?
A: Yes, SAM can vary based on operator skill, machine efficiency, working conditions, and the specific allowance policies of different factories.
Q5: How is SAM used in production planning?
A: Production planners use SAM to calculate daily production targets, line balancing, and overall production capacity of the factory.
