| Abstract: | For the period investigated, the non-defective products is 93.57% of the total water production output with a percentage defectives of 6.42% made of production floor and defective returns from sales. The distribution pattern of defective with fractional defectives can be approximated to a normal distribution and are then used to construct a revised control chart with fractional defectives based on a confidence level of 99.73% to apply for defectives control in the sachet water production industries. From the operating characteristic (OC) curves and average outgoing quality (AOQ) curves, for varying sample sizes for a given constant acceptable percentage defectives, important sampling plan parameters such as acceptable quality level (AQL), lot tolerance percent defective (LTPD) and average outgoing quality level (AOQL) are also presented. |
