The Dyed-Yarn Quantity Estimation for the Loop Pile Carpet: A Case Study

Abstract

This paperms purpose is to create an equation that estimates the quantity of dyed yarn needed for theloop pile carpet tufting process. Because the loop pile carpet is the main product of a case study factory butthe current dyed-yarn calculation method were flawed. Based on 289 collecting data, found that only 22percent of the orders are acceptation cases. In this paper, the CAT data (which looks at the difficulty levels ofthe tufting process) and shades were changed from a qualitative scale to a quantitative one. The authorcreated the multi-linear regression for dyed-yarn estimation and then tested the equation by collecting the new30 orders and compared the current method with the new methodvfinding a 5.27 percent decrease in theover-estimate cases (from 19 to 18), the acceptation cases are increases from 4 cases to 5 cases (25 percent)and a 42.5 percent decrease (from 30.1 to 17.3 percent) in the average return rate of the unused yarn from theprocessing.
