Industrial Engineering
SAM, time study, GSD, line balancing, efficiency and more - the core of IE in garment factories.
Bottleneck in Production — How to Identify and Fix
A bottleneck limits the entire line output. Learn how to find and fix it.
Solved IE exam problems: group efficiency, pitch time, throughput time and thread requirement
Two real written-test problems for IE executives, solved step by step: line and group efficiency and performance, pitch time, balancing ratio, throughput time, production achievement and thread cones for an order.
IE interview questions & answers: work study, time study and SMV
The 22 questions IE executives and MTOs are asked most - work study, method study, basic and standard time, cycle time, capacity, SMV, productivity and efficiency - with short, clear answers.
WIP and bottlenecks on the sewing floor
How much work-in-progress a line needs, how to read WIP to find bottlenecks, and how to control it.
An introduction to GSD for garment engineers
What General Sewing Data is, how predetermined motion times work and why factories use it for SAM.
Man Machine Ratio (MMR): what it tells management
How to calculate MMR, why it matters for cost and how to improve it without hurting output.
Line efficiency and operator efficiency explained
The two efficiency numbers every garment factory reports, how to calculate them and what they really tell you.
Line balancing in garment sewing lines
Find the bottleneck, calculate pitch time and balance loss, and move work so every operator is used well.
Time study step by step: rating and allowance
How to run a capacity study on the sewing floor that gives numbers you can trust.
