Because of the many limitations traditional failure mode effect and criticality analysis (FMECA), an integrated risk assessment model with improved FMECA, fuzzy Bayesian networks (FBN), evidence reasoning (ER) is proposed. A new characterization parameter system constructed in model. rule base based on confidence structure by combining set theory expert knowledge, BN technology used to realize ...

Oil pumps are crucial equipment in pipeline transportation, and their safe reliable operation is essential for the smooth efficient of oil station associated pipelines. The failure can result significant consequences, making it to evaluate safety effective maintenance system prediction. Failure mode, effects, criticality analysis (FMECA) a quantitative fault technique that assigns priority mode...

background: the reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. defect and failure in one part of a system can cause total system breakdown or accident. the failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. the purp...

The goal of the FMECA (Failure Mode, Effects and Criticality Analysis) process is to determine the consequences that failures may have on the function of a complex system. In aeronautic industries, this process is very important and must comply with international standards. Today, most of the process is performed manually. This can be problematic, since, although the basic process is not diffic...

Radical Maintenance (RM) takes the root causes of failures as executive objects to make maintenance decisions. A Root Cause Analysis (RCA) is carried out on the function failure of equipment to performRMand to create a maintenance plan using the combined methods of Failure Mode, Effects and Criticality Analysis (FMECA), and Fault Tree Analysis (FTA). Evaluation criteria andmatrixes of criticali...

Accident analysis in radiotherapy highlighted the need to increase quality assurance (QA) programs by identification of failures/errors with very low probability (rare event) but severe consequences. In this field, a Failure Mode, Effects and Criticality Analysis (FMECA) technique, used various industrial processes rank critical events, has been met much interest. The literature describes diffe...

Quality control is one of the keys to success a company. PT Tirta Sukses Perkasa manufacturer Bottled Drinking Water (AMDK) that strives improve quality its goods in order satisfy customers. The goal be able identify elements can affect product failure or defects produce results meet consumer expectations. This study find main problem excessive by using Control Circle (QCC) approach. next stage...

The Failure Mode, Effects, and Criticality Analysis (FMECA) is one of the risk analysis techniques proposed by ISO 14971 Standard. This allows to identify assess consequences faults that affect each component a complex system. FMECA forward-type technique used for highlighting critical points classifying them priority. It also makes it possible evaluate extent failures means numerical indices. ...

Currently, intelligent ships are still in the early stages of development terms autonomous navigation and berthing, so almost no source fault data can be obtained. Conducting an in-depth analysis failure modes is critical to optimizing design smart ensuring their normal safe navigation. In this paper, fixed-weight Failure Mode Effects Criticality Analysis (FMECA) combined with decision-making t...
