Nowadays, improving and upgrading quality of products and services is one the main reason for outgoing the competitors and penetration into markets. This article is about the deficiency of the traditional FMEA, and introduces a new method based on estimated costs fuzzy FMEA and utility values. In the proposed method a new fuzzy RPN is defined. A pair wise comparison among Severity, Occurrence a...

Failure Mode and Effects Analysis (FMEA) is a technique used in the manufacturing industry to improve production quality and productivity. It is a method that evaluates possible failures in the system, design, process or service. It aims to continuously improve and decrease these kinds of failure modes. Adaptive Resonance Theory (ART) is one of the learning algorithms without consultants, which...

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...

This article aims to show few advanced approach method for improving Failure Mode and Effect Analysis (FMEA). The possible failure situations in the system design are investigated separately considered a Hierarchical FMEA worksheet form. authors propose three different methodological methods based on hybridized fuzzy logic FMEA.

FMEA is a systematic process for indentifying potential design or process failure before they occur. The aim is to eliminate them or minimize the risk associated with them. The method is a procedure to analize failure modes and clasified them by severity. It is a systematic process for identifying potential failures before they occur with the intent to eliminate them or minimize the risk associ...

Constructability analysis and the resulting adjustments in facility design have a significant potential in improving cost effectiveness of construction projects. However, traditional constructability knowledge acquisition techniques are the key barrier to successful constructability improvement. A new approach to automated constructability lessons-learned documentation and constructability anal...

Failure mode and effects analysis (FMEA) is a popular and useful approach applied to examine potential failures in different products, designs, processes, and services. As a vital index, the risk priority number (RPN) can determine the risk priorities of failure modes by some risk factors such as occurrence (O), severity (S), and detection (D). However, in FMEA, the traditional risk priority nu...

The main research intent of this paper is to introduce the use of fault tree analysis (FTA) and failure mode and effects analysis (FMEA) in conjunction to analyse the risk and reliability of a complex mechatronic system in both qualitative and quantitative manner. The major focus is on handling imprecise and vague information with the help of fuzzy synthesis of information. A complex mechatroni...

the failure mode and effects analysis (fmea) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. one important issue of fmea is the determination of the risk priorities of failure modes. risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. in this study, we applied...

Quality function deployment (QFD) is a customer-driven approach in processing new product developments in order to maximize customer satisfaction. Determining the fulfillment levels of design requirements (DRs) and parts characteristics (PCs) is an important decision problem during QFD activity processes for new product development. Unlike the existing literature, which mainly focuses on the de...
