A revised FMEA application to the quality control management

Abstract

Purpose – The purpose of this paper is to propose a cost-effective, time-saving and easy-to-use failure modes and effects analysis (FMEA) system applied on the quality control of supplied products. The traditional FMEA has been modified and adapted to fit the quality control features and requirements. The paper introduces a new and revised FMEA approach, where the “failure concept” has been modified with “defect concept.” Design/methodology/approach – The typical FMEA parameters have been modified, and a non-linear scale has been introduced to better evaluate the FMEA parameters. In addition, two weight functions have been introduced in the risk priority number (RPN) calculus in order to consider different critical situations previously ignored and the RPN is assigned to several similar products in order to reduce the problem of complexity. Findings – A complete procedure is provided in order to assist managers in deciding on the critical suppliers, the creation of homogeneous families overcome the complexity of single product code approach, in RPN definition the relative importance of factors is evaluated. Originality/value – This different approach facilitates the quality control managers acting as a structured and “friendly” decision support system: the quality control manager can easily evaluate the critical situations and simulate different scenarios of corrective actions in order to choose the best one. This FMEA technique is a dynamic tool and the performed process is an iterative one. The method has been applied in a small medium enterprise producing hydro massage bathtub, shower, spas and that commercializes bathroom furniture. The firm application has been carried out involving a cross-functional and multidisciplinary team.

Pengendalian Kualitas Produk Cacat Batang Alumunium Ec Grade Menggunakan Pendekatan Failure Mode and Effect Analysis

“…Penelitian sebelumnya, analisis pengendalian kualitas dilakukan dalam upaya mengendalikan tingkat kerusakan produk dengan menggunakan alat bantu statistik [1], dengan pendekatan Six Sigma dan Analisis Kaizen Serta New Seven Tools [2,3,4]. Penggunaan FMEA juga dilakukan dalam mengidentifikasi resiko kegagalan [5,6], melakukan analisis pengendalian kualitas dengan pendekatan proses [7], analisis kualitas produk [8], analisis produktivitas mesin [9], dan analisis beban kerja [10], maka pengunaan aplikasi FMEA terus di kembangkan dalam analisis pengendalian kualitas [11].…”

Minimization of Pipe Production Defects using the FMEA method and Dynamic System

“…This value is used to rank potential process failures. The RPN values are multiplications of severity, occurence and detection [3].…”

A Rule-Based System for Quality Control in Brake Disc Production Lines

“…This expert system can result in potential failures and considers data as the main module to implement preventive measures to reduce failure occurrence, enhance product performance, and manage FMEA knowledge for product quality improvement in brake disc production lines. FMEA is a well-known tool for assessing potential failure modes for products or processes by identifying potential product defects, their causes, and their consequences affecting operation and the environment [10,11]. While expert systems play a role in dealing with computer programs that have the ability to make decision-making to solve specific problems [12].…”
