Predictive ModellingUsing Regression to Predict Dyeing Recipe Cost Before the Batch RunsA simple multiple regression on shade depth, fabric type and machine liquor ratio predicts chemical cost per kilogram within about 6 per cent, which is close enough to quote from.Salauddin Ahamed Sagar · Aug 26, 2026 · 0 min read
Dyeing & FinishingReactive Dyeing of Cotton: The Control Points That Decide Right-First-TimeRFT rates below 80 per cent are almost never a dye problem. They are a control problem — salt dosing, temperature ramp, liquor ratio and substrate preparation, in that order.Salauddin Ahamed Sagar · Aug 17, 2026 · 0 min read
Scheduling & SequencingJohnson's Rule and What to Do When It Does Not ApplyA two-machine flow shop has an exact optimal sequence you can compute by hand in minutes. Three machines does not. Here is the rule, the extension, and the dispatching heuristics for everything else.Salauddin Ahamed Sagar · Aug 1, 2026 · 0 min read
Queuing TheoryQueuing Theory on the Factory Floor: Sizing Buffers Without GuessworkWhy a line running at 95 per cent utilisation has queues eight times longer than one at 80 per cent, and how to use that relationship to decide where buffer space is worth the floor area.Salauddin Ahamed Sagar · Aug 9, 2026 · 0 min read
Industrial EngineeringStandard Minute Value: How to Calculate It and Why Your Costing Depends on ItSMV sits underneath your CM price, your line plan and your efficiency figure. Get the rating and allowances wrong and every number downstream is wrong in the same direction.Salauddin Ahamed Sagar · Aug 11, 2026 · 0 min read
