1. What is Man Machine Ratio?

The Man Machine Ratio (MMR) is a key performance indicator in the garment industry that measures the relationship between the number of workers and the number of machines in a production facility. It helps manufacturers optimize workforce allocation and machine utilization.

2. How Does the Calculator Work?

The calculator uses the MMR formula:

Where:

• \( \text{Total Manpower} \) — Total number of workers/operators
• \( \text{Total Machines} \) — Total number of operational machines

Explanation: The ratio indicates how many workers are assigned to each machine. A lower ratio typically indicates higher automation and efficiency.

3. Importance of MMR Calculation

Details: Calculating MMR helps garment manufacturers optimize production efficiency, reduce labor costs, improve machine utilization, and make informed decisions about workforce planning and equipment investment.

4. Using the Calculator

Tips: Enter the total number of workers and total number of machines. Both values must be valid (manpower ≥ 0, machines > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is an ideal MMR in garment industry?
A: The ideal ratio varies by production type, but typically ranges from 0.8 to 1.2 workers per machine, depending on automation level and operation complexity.

Q2: How can MMR be optimized?
A: Through better workforce planning, multi-skilling operators, implementing lean manufacturing, and investing in automated equipment.

Q3: Does MMR affect production efficiency?
A: Yes, an optimized MMR can significantly improve production efficiency, reduce idle time, and increase overall output.

Q4: Should MMR be calculated for entire factory or by department?
A: Both approaches are useful. Department-level MMR helps identify specific areas for improvement, while factory-level MMR gives an overall picture.

Q5: How often should MMR be monitored?
A: MMR should be monitored regularly (monthly or quarterly) to track efficiency improvements and make timely adjustments to workforce and equipment.
