The COVID-19 pandemic broke out and the global logistics industry suffered severe losses; therefore, Fuzzy FMEA-AHP (Fuzzy Failure Mode Effects Analysis-Analytic Hierarchy Process) method is proposed to analyze failure reasons of system in pandemic. In this article, we have made an optimization on basis FMEA method: fuzzy integrated into algorithm, referred as F-RPWN (fuzzy risk priority-weight...

Being one of the most expensive components of an electrical power plant, the failures of a power transformer can result in serious power system issues. So fault diagnosis for power transformer is highly important to ensure an uninterrupted power supply. Due to information transmission mistakes as well as arisen errors while processing data in surveying and monitoring state information of transf...

This study aims to evaluate the hazards of stainless tank production process in a company by using Integrated Analytic Hierarchy Process (AHP) and Failure Mode Effect Analysis (FMEA) methods. First, were identified. Identified assessed with FMEA method calculate Risk Priority Number (RPN) for each hazard. The same then weighted AHP method. Finally, are integrated achieve more objective result t...

This paper discusses the determination of reliability index power distribution system. The system is strongly influenced by duration and frequency disturbance, causing customers not to receive electrical energy. measured indices called SAIFI, SAIDI, CAIDI. method used calculate failure rate required determine indexes are section technique Failure Mode Effect Analysis (FMEA). results obtained us...

A dam construction project is exposed to various risks due the amount of investment, duration implementation, complexity design and etc., these will lead human financial losses. Thus, based on three principles, including (i) time, (ii) quality, (iii) cost, identifying, assessing, ranking risks, Occupational Safety Health (OSH) can have a significant impact objectives. The machinery maintenance ...

Signalling, a complex system is one of the most important infrastructures of railway service. The performance of railway signalling system depends on the functioning of a number of subsystems, such as panel, cable, relay, point and point machine, trackcircuit, signal, back indication, point-drive card, signal-drive card, and level crossing gate. Railway signalling system plays an important role...

BACKGROUND A multidisciplinary and multi-institutional working group applied the Failure Mode and Effects Analysis (FMEA) approach to assess the risks for patients undergoing Stereotactic Body Radiation Therapy (SBRT) treatments for lesions located in spine and liver in two CyberKnife® Centres. METHODS The various sub-processes characterizing the SBRT treatment were identified to generate the...

China Train Control System (CTCS-3) is a safety critical computer system that features large-scale, complex structure, and redundant configuration. CTCS-3 and as well as the equipment and technologies related to it can ensure the safety and reliability running of highspeed trains, and so the assessment on its reliability becomes very important. Generally, the two elements such as common cause f...
