Comparative Study of the Inspection Parameters for AQL 2.5% and 1.5% in Garments Manufacturing Process

Quality control is a procedure or set of procedures intended to ensure that a manufactured product to meet the requirements of the customers. To meet the customer requirement the finished products should be inspected in order to assure that it does not contain any faults. In making a decision regarding acceptance inspection for any particular purpose, it may be desirable to consider not only various possible systems or procedures of acceptance sampling by attributes but also the alternatives of [1] no inspection at all, but imposition of a requirement that statistical evidence of satisfactory quality be provided with each lot; [2] 100% inspection; and [3] possibilities of acceptance sampling by variables. This paper is focused on the comparison of different AQL which is fundamental for quality control in final inspection process. This study was entirely conducted in a garment manufacturing company for authentic data. Similarities and dissimilarities in inspection parameter for AQL 2.5% and 1.5% were obtained by observing and analyzing collected data. The research work carried out here may be considered as a significant step to inspection process regarding quality confirmation.
