Failure mode and effects analysis (FMEA) is an analysis tool for identifying and preventing flaws or defects in products during the design and process planning stage, preventing the repeated occurrence of problems, reducing the effects of these problems, enhancing product quality and reliability, saving costs, and improving competitiveness. However, FMEA can only analyze one influence factor ac...

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 manu...

Failure mode and effects analysis (FMEA) is a widely used engineering technique for designing, identifying and eliminating known and/or potential failures, problems, errors and so on from system, design, process, and/or service before they reach the customer (Stamatis, 1995). In a typical FMEA, for each failure modes, three risk factors; severity (S), occurrence (O), and detectability (D) are e...

Abstract Practical uses of Failure Modes and Effects Analysis (FMEA) range from the identification of potential design defects and safety hazards, to maintenance planning, diagnostics and Prognostics and Health Management (PHM). According to the broadly accepted standard for FMEA, MIL-STD-1629A, a successful FMEA is one that conducted in a timely manner, so that the results can be used to ident...

Failure Mode and Effects Analysis (FMEA) is a widely used dependability and safety technique aiming at systematically identifying failure modes, their causes, their effects, and the countermeasures that could mitigate their impact. Although FMEA has been thought for hardware, its use is also advocated for software (SW-FMEA). However, this involves several major hurdles such as the complexity of...

a r t i c l e i n f o Keywords: Failure mode and effects analysis Data envelopment analysis Overall risks Risk priority ranking Failure mode and effects analysis (FMEA) is a method that examines potential failures in products or processes and has been used in many quality management systems. One important issue of FMEA is the determination of the risk priorities of failure modes. In this paper ...

PURPOSE Failure mode and effects analysis (FMEA) was used to evaluate a smart i.v. pump as it was implemented into a redesigned medication-use process. SUMMARY A multidisciplinary team conducted a FMEA to guide the implementation of a smart i.v. pump that was designed to prevent pump programming errors. The smart i.v. pump was equipped with a dose-error reduction system that included a pre-de...

The concept of software failure mode and effects analysis (FMEA) has grown in attractiveness over recent years as a way of assessing the reliability of software. Like its hardware counterpart, software FMEA is immensely tedious for an engineer to perform, as well as being error-prone. This paper presents the implementation of a novel method for automating code-level software FMEA based on treat...
