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...
This paper describes how the effects of possible component failures on an electrical system can be predicted through simulation of the correct behavior of the system, and repeated simulation of versions of the system containing faulty components. The results of such simulation are useful both for failure mode and effects analysis (FMEA), and for diagnosis. Such results have been used commercial...
For proper management of life cycle of machines and manufacturing facilities, it is important to perform appropriate maintenance operations, and to keep machine status for better reuse and recycling opportunity. For this purpose, a virtual maintenance system is very effective, where facility life cycle model is constructed in computer, and reliability and availability of machines are predicted ...
In this paper we propose a computer-aided solution with Genetic Algorithms in order to reduce the drafting of reports: FMEA analysis and Control Plan required in the manufacture of the product launch and improved knowledge development teams for future projects. The solution allows to the design team to introduce data entry required to FMEA. The actual analysis is performed using Genetic Algorit...
مقدمه: روش fmea یکی از روش های پر کاربرد در ارزیابی و اولویت بندی ریسک می باشد؛ لیکن به چندین دلیل، کاربرد آن در عمل دچار محدودیت می باشد. این مطالعه با هدف حذف این محدودیت ها، با استفاده از اصول منطق فازی و تئوری خاکستری در قالب اعداد z و روش تصویر خاکستری (grp) انجام شد. روش کار: مطالعه حاضر از نوع تحلیلی-مقطعی بوده که به منظور اولویت بندی ریسک های جرثقیل سقفی انجام گردید. ابتدا یک تیم fmea م...
FMEA has been used for several years and proved its efficiency for system’s risk analysis due to failures. Risk priority number found in FMEA is used to rank failure modes that may occur in a system. There are some guidelines in the literature to assign the values of FMEA components known as Severity, Occurrence and Detection. This paper propose a method to assign the value for occurrence in mo...
Failure mode and effect analysis (FMEA) is a widely used reliability analysis and risk assessment tool in various industries. It is one of the most established project management techniques to identify and eliminate failures before actual manufacturing starts. In traditional FMEA, Risk Priority Number (RPN) ranking system is used to evaluate; the risk level of failures, to rank failures, and to...
