Probabilistic Risk Assessment (PRA) is a method of estimating system reliability by combining logic models of the ways systems can fail with numerical failure rates. One postulates a failure state and systematically decomposes this state into a combination of more basic events through a process known as Fault Tree Analysis (FTA). Failure rates are derived from vendor specifications, historical ...

FMEA(Failure Mode and Effects Analysis) is a systematic method of identifying and preventing system, product and process problems. As a standard document, FMEA is produced during the design of products or systems. However, FMEA documentation is rarely validated or updated in practice after it was generated. FMEA validation remains a challenge. In this technical report, we propose to validate FM...

Suatu proyek bidang infrastruktur tentu mempunyai sasaran durasi pengerjaan yang wajib dilaksanakan dengan cepat serta tepat. Tetapi, pada faktanya selalu terdapat kendala membatasi tersebut, salah satu pemicu terbentuknya keterlambatan dalam adanya kecelakan kerja. Pelaksanaan pembangunan Gedung Laboratorium DLH Banyuwangi tahap II pekerjaan struktur terjadi beberapa kasus kecelakaan kerja yai...

BACKGROUND Failure Mode and Effects Analysis (FMEA) is a prospective risk assessment tool that has been widely used within the aerospace and automotive industries and has been utilised within healthcare since the early 1990s. The aim of this study was to explore the validity of FMEA outputs within a hospital setting in the United Kingdom. METHODS Two multidisciplinary teams each conducted an ...

Power network stability requires a timely failure detection and operator reaction. The protection devices and operators have responsibilities for the failure detection in a power system. In other words, alarms being received from the protection devices are displayed to the operator by SCADA to respond to the respective appropriate and timely actions to be done. This article is a part of a risk ...

IMPLEMENTATION OF RELIABILITY CENTERED MAINTENANCE METHOD ON CRITICAL COMPONENTS STEAM TURBINE AT PT MADUBARUSteam turbine is a machine that can be used to convert heat energy from steam into mechanical so it produce electrical energy. As source of energy, Madubaru utilizes this turbine. The purpose research determine the Mean Time To Failure or MTTF and Repair MTTR values which components have...

State Enumeration technique for reliability evaluation is the process of selecting and assessing the impact of all possible contingencies in a given system. It starts with first order failure states to higher orders depending on the resolution requirement. In general higher order failure states do not contribute significantly to the results and are usually neglected from an engineering viewpoin...

Failure behavior analysis is a very important phase in developing large distributed embedded systems with weak safety requirements which do graceful degradation in case of failures. Today, the analysis will usually be done by standard methods like FTA and FMEA considering the existence of faults, only. Gradations of errors are not regarded, although this is a very coarse system behavior approxi...

Fault tree analysis (FTA) is one of the important methods safety system engineering commonly utilized in various industries to evaluate and improve reliability complex systems. To grasp current situation development trend FTA research further point out FTA’s future directions, 1469 FTA-related articles from literature were retrieved SCIE SSCI databases. Informetric methods, including co-authors...
