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...

Risk assessment is a standard tool in health care systems which is used to improve patient safety. Failure mode and effects analysis (FMEA) as a powerful risk assessment tool for safety and reliability widely applied by industries such as aerospace, nuclear, automotive, chemical, mechanical, medical technologies, and electronics. FMEA is popular technique, but it has some substantial deficienci...

The extent of failure evaluation depends on the complexity and significance electronic products. However, traditional mode effect analysis (FMEA) has many shortcomings, which brings large difficulty to evaluating work. This paper uses double hierarchy hesitant fuzzy linguistic term set (DHHFLTS) K-means clustering algorithm improve shortcomings FMEA. DHHFLTS is a language terms based symmetry m...

Lift-jacking accidents are one of the five common in lift field, characterised as a high hazard. In addition, it is difficult to obtain absolute probabilities risk factors for which ambiguous and uncertain. order solve related problems perform comprehensive assessment lift-jacking accidents, methodology integrated with FFTA (Fuzzy Fault Tree Analysis) FMEA (Failure Mode Effects has been propose...

Actual load, material characteristics and other quantities often differ from the design values. This can cause worse function, shorter life or failure of a civil engineering structure, a machine, vehicle or another appliance. The paper shows main causes of the uncertainties and deviations and presents a systematic approach and efficient tools for their elimination or mitigation of consequences....

Outsourcing is recognized as a strategic instrument for companies to move towards diversified operation advantages and efficient global market. However, outsourcing agreements may fail due insufficient risk consideration evaluation. This requires an effective evaluation approach that necessitates entire comprehension of the system, its requirements dimensions. paper proposes novel fuzzy group m...

Risk management is one of the most important phases of project management and isthe most recently used by many researchers. In this paper, a fuzzy based method wasproposed which identifies different kinds of risks through the project life cycle.Then, the project risk magnitude can be obtained in regards to five factors, namely“severity”, “occurrence”, and “not detection” which form fuzzy FMEA a...

Failure mode and effects analysis (FMEA) is a widely used, powerful tool to identify assess potential failure modes in products make more reliable. Due the complexity of lack knowledge, FMEA involves many uncertainties practice. In previous studies, numerous modified methods based on fuzzy logic Dempster-Shafer (D-S) evidence theory have been employed address these uncertainties. These studies ...

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...
