Malay Niraj, Praveen Kumar, Dr. A.Mishra Abstract -Present study is an approach for f inding the suitable maintenance practice and frequency of maintenance with the help of criticality factor of equipment it is based on failure mode evaluation and criticality analysis. Criticality means the failure probability of the equipment is very high. The miner failure of critical equipment may leads to s...

In System Engineering, one of the most critical process is the requirement management, particularly when it deals with the safety requirements. These one are non-functional requirements and are related to emergent properties, which come from the integration of the different system components. They must be identified as soon as possible, because they are guards to validate or not the system, whi...

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...

Decision making is crucial for the life of many production plants. Good decision need the right information at the right time, and a deep knowledge of the system. This is especially true for older plants that are more prone to failures. Unfortunately, these systems are less rich of monitoring and diagnostics instrumentation, because of their seniority. When the maintenance service is carried ou...

In Systems Engineering Verification and Testing for Reliability and Safety are the most complex, error-prone and expensive tasks. This paper explains how Model Based Systems Engineering Techniques and Methodologies, powered by SysML, can facilitate Agility in Design for Reliability and Safety of Mission-Critical Systems in several Industries like Aerospace, Medical, Automotive, Transportation. ...

Complex engineering systems include several subsystems that interact in a stochastic and multifaceted manner with multiple failure modes (FMs). The dynamic nature of FMs introduces uncertainties negatively impact the reliability, risk, maintenance complex systems. Traditional approaches adopting standalone techniques for managing independently at various stages asset life cycle pose challenges ...

The Fault Mode Effects and Criticality Analyses (FMECA), describe the impact of identified faults. They form an important category of knowledge gathered during the design phase of a satellite, and are used also for diagnosis activities. This paper proposes their extension, allowing a finer representation of the available knowledge, at approximately the same cost, through the introduction of an ...
