( Muhammad Babar Ramzan ),( Chang Wook Kang ) 한국품질경영학회 2014 한국품질경영학회 학술대회 Vol.2014 No.2
1. 목적 · The purpose of this study is to find out the optimal number of quality inspectors with respect to their skill level to meet target values of offline inspection station. 2. 연구설계/ 방법론/ 접근방법 · In manufacturing industry, quality control is considered as important aspect of quality management system. To achieve good control of quality, inspection activities are very essential at different stages like incoming, online and offline. Offline inspection has been extensively studied in past keeping in view the inspection strategies, inspection locations and optimal inspection interval. The present study investigate the effect of human effect on offline inspection. For this purpose, three skill levels of quality inspectors are assumed on the basis of their inspection error, inspection cost and inspection quantity. The objective is to minimize the inspection cost and error by determining the optimal number of quality inspectors of each skill level. 3. 연구결과 · A mathematical model is presented to measure inspection cost, inspection error and inspection quantity. After defining the objective functions, Goal progranm1ing module of QM for windows is sued to detem1ine the optimal number of quality inspectors of each skill level. This optimal num-bers of decision variables will achieve all the objectives of offline inspection that includes low in-spection cost and inspection error with high inspection quantity. Secondly sensitivity analysis is done to show the effect of objective function on inspection cost and number of quality inspectors. 4. 실무적 시사점 · This study determined the efficient combination of labour force for offline inspection that not only decrease cost but also meet the optimal values of inspection error and inspection target. It will al-so helpful for effective utilization of manpower in those industries that still rely on human labour. 5. 독창성/ 가치 · In previous studies, off line inspection was studied at macro level in manufacturing and supply chain industry, but there is a lack of work on human factors with respect to their effect of total inspection cost. This study investigated the effect of human factors that stimulates inspection cost of single offline station in a garment manufacturing industry.
