Overview of FMEA

2013

A failure modes and effects analysis (FMEA) is a procedure in product development and operations management for analysis of potential failure modes within a system for classification by the severity and likelihood of the failures. A successful FMEA activity helps a team to identify potential failure modes based on past experience with similar products or processes, enabling the team to design those failures out of the system with the minimum of effort and resource expenditure, thereby reducing development time and costs.

Failure Mode and Effects Analysis (FMEA) is a structured approach to discovering potential failures that may exist within the design of a product or process. Failure modes are the ways in which a process can fail. Effects are the ways that these failures can lead to waste, defects or harmful outcomes for the customer. FMEA is a methodology aimed at allowing organizations to anticipate failure during the design stage by identifying all of the possible failures in a design or manufacturing process. Developed in the 1950s, FMEA was one of the earliest structured reliability improvement methods. Today it is still a highly effective method of lowering the possibility of failure. FMEA is designed to identify, prioritize and limit these failure modes. FMEA is not a substitute for good engineering. Rather, it enhances good engineering by applying the knowledge and experience of a Cross Functional Team (CFT) to review the design progress of a product or process by assessing its risk of failure. In Pheobus Manufacturing Sdn Bhd, the FMEA is developed and maintained by a multidisciplinary or cross-functional team typically led by the responsible engineer. During the initial development of the FMEA, the responsible team leader is expected to directly and actively involve representatives from all affected areas. These areas should include but are not limited to design, assembly, manufacturing, materials, quality, service, and suppliers, as well as the area responsible for the next assembly. The FMEA should be a catalyst to stimulate the interchange of ideas between the areas affected and thus promote a team approach. FMEA is performed in seven steps, with key activities at each step. The steps are separated to assure that only the appropriate team members for each step are required to be present. The FMEA approach used by Pheobus Manufacturing Sdn Bhd has been developed to avoid typical pitfalls which make the analysis slow and ineffective. There are Seven Steps to Developing an FMEA. First develop FMEA pre-work and assemble the FMEA team. Then, identified the requirements through severity ranking. Third, create the potential causes and prevention controls through occurrence ranking. Then, testing and detection controls through detection ranking. After that, they had to take action priority and assignment for the action taken and design review. Lastly, they need re-ranking RPN and closure the process.

FMEA was formally introduced in the late 1940s for military usage by the US Armed Forces. Later, it was used for aerospace/rocket development to avoid errors in small sample sizes of costly rocket technology. FMEA enables the team to design those failures out of the system with the minimum of effort and resource expenditure, thereby reducing development time and costs. It is widely used in manufacturing industries in various phases of the product life cycle and is now increasingly finding use in the service industry. Although, initially developed by the military, FMEA methodology is now extensively used in a variety of industries including semiconductor processing, food service, plastics, software, and healthcare. Various approaches and applications of FMEA have been developed so far. This paper provides a survey and brief summary of the work on the FMEA from 1977 to 2011.

D. Vykydal, J. Plura, P. Halfarova, P. Klaput, VŠB – Technical University of Ostrava, Faculty of Metallurgy and Materials Engineering, Ostrava, Czech Republic The present paper explores advanced approaches to the FMEA method (Failure Mode and Effect Analysis) which take into account the costs associated with occurrence of failures during the manufacture of a product. Different approaches are demonstrated using an example FMEA application to production of drawn wire. Their purpose is to determine risk levels, while taking account of the above-mentioned costs. Finally, the resulting priority levels are compared for developing actions mitigating the risks.

One of the prevention efforts of medical errors that occur in health services is by identifying the potential failure of the service before the failure occurs. FMEA is one way to identify the risks of failure. Therefore, the authors wanted to find out whether FMEA was effective for reducing medical error based on previous studies. This article was a literature review using references in an online database such as EBSCOhost. The author found 280 articles while searching by using the keyword "FMEA". After filtered by publication period from 2012 to 2017, full text and language, finally got 7 articles. Finally, the author used the three most relevant literature. FMEA was proven to decrease the potential failure rate after follow-up to failure was done in service process, so medical error can be prevented. In the application of FMEA, bias can occur during the determination of potential failure and determination of scoring on RPN. Therefore, it is expected that the team involved in making FMEA experts in the process of service to be designed. FMEA could prevent medical errors by determining potential failures before failure occurs.

The proper using of FMEA method is proven to reduce the cycle of warranty costs and will certainly cost less to prevent than to fix the problems that have already occurred. FMEA also was suitable for assessing risk in information technology or systems aspect. Several studies criticized the FMEA limitation or weakness of using this method. The purpose of this paper is to provide a resume and critical analysis of previous research that discussed the development and limitation of FMEA. A systematic literature review methodology was conducted in order to review FMEA. As a result, 32 papers were obtained in the selection stage according to the criteria used and review based on quality content. Data collection and identification stage was carried out by the selected papers for further analysis and synthesis. The limitation FMEA was due to the subjectivity and caused inconsistent results. This paper provided the critical analysis about the point of weakness FMEA based on document FMEA, and also limitation FMEA based on risk management process. There were eight research questions that could be considered from the results. By conducting a literature review of the development and trending of FMEA research, it provided new research opportunities to proved the FMEA issues reviewed in this paper.

The Failure Mode and Effect Analysis (FMEA) has been developed by several researchers who have proposed distinct reference tables to score the Severity, Occurrence and Detection of a failure. This paper aims to evaluate, using AHP, several proposals for the application of Process FMEA, as well as to obtain and offer recommendations for its application. Five reference tables for Severity, six tables for Occurrence, and six tables for Detection are presented. These reference tables are evaluated for their application in the Brazilian automotive industry by using critical analysis and proper judgments. The scientific contribution of this paper is to provide a way to select a reference table, available in the FMEA literature, for the application of the FMEA process.http://dx.doi.org/10.13033/ijahp.v2i1.69

Failure Mode and Effects Analysis (FMEA) is a model used to prioritize potential defects based on their severity, expected frequency, and likelihood of detection. An FMEA can be performed on a design or a process and is used to prompt actions to improve design or process. There is an uncertainty from manufacturers at present that the setting of criteria’s of FMEA is subjective. There is another problem in determining the priority of resolving failure modes. The paper provides various options for prioritizing failure modes. At the same time, the individual methods specify the parameters for calculating the Risk priority number (RPN). We achieve objectification of criteria’s for RPN calculation in FMEA. These are time-consuming and cost-effective designs. The proposed innovations are an extended RPN, including the creation of an extended FMEA and the use of the DEMATEL model.

Failure Analysis [Working Title]

The analysis of failure modes and effects (FMEA) is a method of analyzing the potential failure of a product or process and developing an action plan aimed at their prevention and increased quality of products, processes, and job production environments. As a method of critical analysis, FMEA has very clear objectives: determination of the weaknesses of a technical system; initiating causes of failure-seeking components; analysis of the environmental impacts, safety of operation, the product value; provision of corrective actions to remove the causes of the occurrence of defects; provision of a plan to improve product quality and maintenance; determining the needs of technology and modernization of production; increasing the level of communication between departments of working people at hierarchical levels. FMEA should be used before taking the product. Subsequently, there is no point, only because the customer demands it, to achieve FMEA. Therefore, FMEA must be within organizatio...
