Analysis of Defects in Trouser Manufacturing: Development of a Knowledge-BasedFramework. Volume 3. SDAS User Manual

摘要

Research has been carried out to analyze defects in apparel manufacturing. Twoknowledge-based software systems--FDAS (Fabric Defects Analysis System) and SDAS (Sewing Defects Analysis System)--have been developed. FDAS covers the common manufacturing defects occurring in greige and finished fabrics, including those in indigo-dyed denims. SDAS covers the defects occurring in the cutting, sewing, finishing and packing departments of an apparel plant producing denim trousers. Based on the visual description of the defect in the fabric (type, orientation and mode of repetition of the defect), FDAS identifies the defect and suggests possible causes and remedies. SDAS uses information on the location and nature of the defect to identify the manufacturing operation causing the defect and displays possible causes and remedies for the defect. SDAS also has a provision to display the relevant construction specifications (MIL-SPEC) for the assembly operation causing the defect. Both FDAS and SDAS are implemented in Nexpert Object and are linked to a relational data base using Oracle. They run under both MS-DOS and Unix environments. Software manuals for using FDAS and SDAS have been produced.
