| dc.description.abstract | As one of the leading helmet manufacturers in Vietnam, X Company produces
up to 1,000-5,000 helmets per day, boasting a large customer base from countries around
the world such as France, Italy, Taiwan… The production model is a pull system, thus
based on orders, the company will proceed with production. However, customer
requirements differ for each order, which poses many potential risks that could cause
errors in the production process. Currently, the company has no plan to anticipate
potential errors that may occur. Therefore, the topic "Applying FMEA Tool to Prevent
Errors in the Production Process of 822BA Helmets at the Assembly Department of X
Company" was decided to undertake. This study aims to identify and seek solutions to
prevent and mitigate actions causing potential errors.
Related theories have been compiled to serve as a basis for the implementation
of the topic. Through analyzing the current quality status at X Company, a specific
subject was selected to carry out the study, which is the 822BA helmet at the Assembly
Department. Potential errors in the process were identified and analyzed to score factors
such as: (1) Severity, (2) Occurrence, and (3) Detection. Data collection on failures were
conducted, analyzed, and discussed potential hazards. Consequently, a catalog of
potential errors was listed and scored the SEV, OCC, and DET indices to calculate the
Risk Priority Number (RPN), using the 80/20 Pareto chart to identify priority errors. The
completed FMEA table indicates the four highest RPN errors that need prioritization for
improvement:
(1) Error LR3.2: Unevenly wound nails, cracks.
(2) Error LR3.5: Foam breaking when inserting foam.
(3) Error LR3.8: Inappropriate tightness of visor lock.
(4) Error LR3.1: Damaging helmet surface when attaching the strap, causing
scratches, cracks.
From the analyzed root causes, preventive solutions for the four priority risks
were proposed, then the proposed solutions were evaluated | en_US |
