Abstract

In manufacturing field, the intense global competition and rapidly changing markets require manufacturers to struggle with these highly competitive circumstances. Consequently, maintaining the machinery equipments in a highly reliable condition is a must to adapt and satisfying the customer preferences in an ever-changing business environment. Therefore, the purpose of this study is to improve the reliability of a system in a manufacturing company. Regarding to this requirement, the reliability of each mechanical stamping machine in the production of lower rail at Factory A are measured and assessed. The selection of lower rail production is based on the frequency of breakdown that happen in certain production through an interview with the Process Engineer. In order to measure and assess the reliability, Life Data Analysis is used where reliability value can be determined. However, there is a limitation that needs to be considered where only four stamping machines are assessed and the painting process is excluded since the process is done without the use of machine. From this analysis, the machine that contributes to low reliability of the system is identified. Then, Failure Mode Analysis using the Minitab software is used to identify the main cause of failure that prevents the machine to perform its required function. Both findings from these two objectives help in suggesting the improvement by considering the system configuration and cause of failure in achieving better reliability of the system. It can be concluded that this project can help the company to identify unreliable component which in turn maximize the reliability of the system in production.
