In the present paper, a complete process from reliability evaluation to design modification is proposed and also applied to a newly designed and manufactured Remotely Piloted Helicopter (RPH) by the authors. First of all, a description of all platform subsystems is presented. After that, function diagram and also product tree of the whole system is depicted for further analysis. Then, the relia...

Selective Production of Exotic Species is an innovative plant for advanced nuclear physic studies. A radioactive beam, generated by using UCx target-ion source system, ionized, selected and accelerated experimental objects. Very high vacuum conditions appropriate safety systems to storage exhaust gases are required avoid radiological risk operators people. In this paper, Failure Mode, Effects, ...

Este trabalho apresenta uma nova metodologia de suporte às ações efetivas manutenção ativos para o sistema excitação dos geradores da Usina Hidrelétrica Governador José Richa (UHE-GJR). A proposta é baseada em análise Fuzzy-FMECA. O modelo desenvolvido permite a busca por possíveis aperfeiçoamentos nas atividades contemplando otimização recursos humanos e materiais, com foco na confiabilidade d...

The performance of electronic vehicle PHM relies not only on the diagnostic and prognostic algorithms used, but also on the types, location, and number of sensors selected. The paper firstly presents the architecture for PHM. Sensor localization and selection for fault diagnostic purposes is the importance part. It introduces the new sensor approach for PHM, such as smart sensor. Sensor localiz...

The quality safety traceability of meat food has played important role in governmental law, food industry management strategies, and consumers. Many institution and software companies have developed a lot of traceability system. There is a growing perception to implementation of reusability, multi resource data fusion and information sharing of the different system. The conceptual model is the ...

The paper describes modern technologies of Computer Network Reliability. Software tool is developed to estimate of the CCN critical failure probability (construction of a criticality matrix) by results of the FME(C)A-technique. The internal information factors, such as collisions and congestion of switchboards, routers and servers, influence on a network reliability and safety (besides of hardw...

Reliability Centered Maintenance(RCM) is one of most widely used methods in the modern power system to schedule a maintenance cycle and determine the priority of inspection. In order to apply the RCM method to the Smart Grid, a precedence study for the new structure of rearranged system should be performed due to introduction of additional installation such as renewable and sustainable energy r...

Medical robots can perform complex tasks and share their working area with humans. Therefore, they belong to safety critical systems. In nowadays development process, safety is often managed by the way of dependability techniques. We propose a new global approach, based on the risk concept in order to guide designers along the safety analysis of such complex systems. Safety depends on risk mana...

Some high integrity software systems require the rigorous validation of safety properties. Assessing whether software architectures are able to meet these requirements is of great interest: to avoid the risk that the implementation does not fulfill requirements due to a bad design, and, to reduce the development cost of safety critical parts of the system. Safety analyses like FMECA and FTA are...

This paper will focus on the management and improvement of equipment availability with better prevention of failures. It is focused on one of process control tasks: preliminary risks analysis. The result from this study is a method which empowered engineers and managers decision about actions to implement regarding negative events in their manufacture. The article proposes a risk based maintena...
