What is TMU?
TMU, or Time Measurement Unit, is a standard unit of time used to measure and analyze work in industrial engineering. It is primarily used in methods-time measurement (MTM) systems for assessing and standardizing manual operations.
It is a small unit of time used in the Methods-Time Measurement (MTM) system. This system assigns a predetermined amount of time to basic motions, such as reaching, grasping, or moving an object, based on their complexity and effort required.
Conduct Motion Study
Identify and eliminate unnecessary motions during sewing operations. Optimise operator movements to reduce operation cycle time. Do Method Study or analyse the operation to record the motion, motion sequence and required time needed for those each motions, re-sequence, eliminate and rearrange the motion therefore do and adjust anything from the findings in your analysing to reduce the process time actually.
Determining the Standard Allowed Minutes (SAM) from garment images presents several challenges. SAM is a crucial metric in the garment manufacturing industry, used to determine the standard time required to produce a garment. However, extracting this information from images, especially automated systems, faces multiple hurdles. These challenges include:
1. Complexity of Garment Features
In garment manufacturing, one of the most critical yet often overlooked factors affecting overall productivity is Style Changeover Time (COT). This term refers to the period between the last piece of the previous style coming off the production line and the first piece of the new style being produced. Ideally, this changeover time should be as short as possible to minimize downtime, increase machine utilization, and maintain production flow. A prolonged COT not only hampers productivity but also increases costs and delays customer orders.
In garment production system, one of the most critical and difficult tasks is to determine the right rate for each sewing operation. This is often done on a "piece-rate" basis, where workers are paid as per the number of garments they can make, or the number of specific sewing operations they complete. However, setting a fair and accurate rate involves more than just a guess. In this writting, we’ll explore how to calculate the individual operation rates, with a focus on scientific methods, and discuss the factors that influence the pricing of different sewing tasks.
Setting daily production targets in apparel manufacturing involves evaluating both Standard Allowed Minutes (SAM) and Cycle Time. These two metrics are critical for determining how efficiently a factory can produce garments. Here’s how you can set daily production targets using each of these methods:
SAM represents the time allowed for a skilled worker to complete a specific task or a unit of work under normal working conditions. It accounts for the complexity of the garment and includes allowances for rest, fatigue, and other non-productive activities.
Textile fibers can be classified into two main categories:
Natural fibers and Synthetic fibers.
Here’s a breakdown of each category......
