They can allocate the right number of workers with the necessary skills to each task, ensuring optimal utilization of human resources and avoiding any overburdened or idle workers.

 

3. Factors Affecting SMV Calculation in Garments

 

Garment Complexity and Design

The complexity and design intricacies of a garment directly impact the SMV calculation. A more intricate design may require additional time for stitching, finishing, or adding embellishments, thereby increasing the SMV.

 

Material Selection and Availability

The type and availability of materials affect SMV calculation as different fabrics and trims may require specific handling techniques or additional time for precision work.

 

Workplace Layout and Equipment

Efficient workplace layout and the availability of appropriate equipment can significantly influence SMV. A well-organized layout and modern machinery help in reducing unnecessary movements and time wastage, ultimately impacting the SMV positively.

 

4. Methods and Techniques for SMV Calculation

 

Time Study Method

The time study method involves observing and analyzing a sample of workers performing a particular operation to determine the average time taken. This data can then be used to calculate the SMV for that operation.

 

Predetermined Motion Time System (PMTS)

PMTS involves breaking down each operation into smaller, predefined motions and assigning a predetermined time value to each motion. The cumulative time of all the motions gives the SMV for the operation.

 

Data Analysis and Benchmarking

Analyzing production data and comparing it against industry benchmarks can help in determining the SMV for different operations. This method allows manufacturers to identify areas where they are lagging behind and set realistic targets for improvement.

 

Remember, accurately calculating SMV is crucial for effective production planning, cost control, and overall efficiency in the garments industry. So, don't underestimate the power of those precious minutes!5. Tools and Software for SMV Calculation
