Abstract

This project aims to provide a design of an improvised acceptance sampling system as a part of the Quality Control (QC) activity in some production processes of Painting & Sticker Division at PT. X. Repair calls for defectives known externally until receiving more customer complaints become some continuous concerns for the company. One technique for analyzing its sampling system is through looking to its Probability of Acceptance (Pa), Average Outgoing Quality (AOQ), and Average Total Inspection (ATI) value. This project sets AOQ value as the topmost judgement parameter to determine a better acceptance sampling system. This is due to external failures and continuous complaints acquired in which caused by a poor quality detached from the Painting & Sticker Division. Result shows that the current acceptance sampling system produces a thin gap between its AOQ and initial quality value (calculated from the average defect/unit in June-December 2019). On the other hand, its AOQ given by the improvised acceptance sampling system shows a lower value in comparison. A lower AOQ of an acceptance sampling system will benefit company at some aspects, such as decrease of external failure cost and complaints.

Abstract

Company X is a company engaged in the furniture sector. The company has been established since 2003. Company X has a problem, which is that it is still unable to design new product specifications and determine which current products need to be produced again using past demand data. This causes high RnD (Research and Development) cost losses. These costs include drafting costs, costs for making frame molds, fabrics, foam, and prototype costs. With the application of BI to company X, the specifications of the sofa can be found out according to the interests and needs of consumers. The data used in this study are sales from January 1, 2021 to June 30, 2022. The method used to conduct this research is the decision tree version ID3 and C4.5. After being tested using cross-validation 10 times, the results of the accuracy show that the C4.5 version of the decision tree is more accurate than the ID3 version. The results of this study are to determine the sofa specifications that customers are interested in based on price segmentation. Categories based on price are divided into 3, namely PR3, PR2, and PR1. There are 6 significant sofa specifications in PR2. There are 3 significant sofa specifications in the PR3.
