Reliability, Technological Risks and Maintenance Decisions


Article Preview

The paper presents, in a synthetic manner. some points of view regarding the necessity of a balanced approach to reliability and engineering risk. It presents some of the risk reduction principles applied in the processes of improving reliability and reducing risk (such as introducing redundancy) and some of the key principles for reducing the risk of failure that can be applied with success. One does have also in view that critical failures in many industries can have disastrous environmental and health consequences. Such failures entail loss of production for very long periods of time and extremely high costs of the intervention for repair. Consequently, for industries characterised by a high cost of failure, setting quantitative reliability requirements must be driven by the cost of failure. Failure rate modelling is relevant for reliability analysis and other disciplines that employ the notion of the failure rate or its equivalents
