Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering. The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system. For example, an automobile's failure rate in its fifth year of service may be many tim… WebJan 17, 2024 · Understanding whether the undesirable failures are due to infant mortality, or early wear out, or a batch defect is a critical piece of information when investigating an asset's failure history ...
