| Abstract | ||
| This paper is an attempt to improve the quality level of an industrial product (Ishtar Kerosene Heater) in Light Industries Company by using Demerit Control Chart (U-chart). Demerit per defected unit (U) was calculated to determine the control limits for selected thirty samples. The results showed that the production process was under controlled according to the statistical recorded data. Also, the defects classes A and B have no influence of the product performance. Additionally, it was found that the percentage of the quality level of product was ranging between (80-100%), indicating that this level is quite good.ﻳﻌﺘﱪ ﻫﺬ ﺑﲔ | ||
