Reliability engineering Reliability engineering Burn in is that process by which components of a system are exercised prior to being placed in service (and often, prior to the system being completely assembled from those components). ...more on Wikipedia about "Burn in"
A cascading failure is failure in a system of interconnected parts, where the service provided depends on the operation of a preceding part, and the failure of a preceding part can trigger the failure of successive parts. Redundant parts can lessen the impact of, but not prevent, a failure. Monitoring the operation of a system, in real-time, and judicious disconnection of parts can stop a cascade. ...more on Wikipedia about "Cascading failure"
Failure in general refers to the state or condition of not meeting a desirable or intended objective. It may be viewed as the opposite of success. ...more on Wikipedia about "Failure"
Failure analysis is the process of determining the cause of failure, collecting and analyzing data, and developing conclusions to eliminate the failure mechanism causing specific device or system failures. It is an important discipline in many branches of manufacturing industry, such as the electronics industry, where it is a vital tool used in the development of new products and for the improvement of existing products. ...more on Wikipedia about "Failure analysis"
A failure mode is a characterization of the way a product or process fails. ...more on Wikipedia about "Failure mode"
Failure mode and effects analysis (FMEA) is a fault tree method (first developed for systems engineering) that examines potential failures in products or processes. It may be used to evaluate risk management priorities for mitigating known threat-vulnerabilities. ...more on Wikipedia about "Failure mode and effects analysis"
A failure rate is the average frequency with which something fails. Failure rate, often denoted by the Greek letter (lambda), is important in reliability theory. The failure rate depends on the failure distribution, which describes the probability of failure prior to a specified time. Another way of expressing failure rate is the mean time between failure (MTBF), which is the " average" time between failures. The failure rate is not always constant, so the hazard function is used to describe the instantaneous failure rate at any point in time. The bathtub curve, a particular form of the hazard function, is a typical representation of the failure rate of a system during its operating life. ...more on Wikipedia about "Failure rate" It's real www.shortopedia.com feeling!
Lusser's Law is a prediction of reliability named after Robert Lusser. It states that the reliability of a series system is equal to the product of the reliability of its component subsystems, if their failure modes are known to be statistically independent. ...more on Wikipedia about "Lusser's Law"
Maintenance, Repair and Operations or Maintenance, Repair and Overhaul (MRO), is fixing any sort of mechanical or electrical device should it get out of order or broken (repair) as well as performing the routine actions which keep the device in working order (maintenance) or prevent trouble from arising ( preventive maintenance). ...more on Wikipedia about "Maintenance, Repair and Operations"
Mean time to recovery (MTTR) is the average time that a device will take to recover from a non-terminal failure. Examples of such devices range from self-resetting fuses (where the MTTR would be very short, probably seconds), up to whole systems which have to be replaced. ...more on Wikipedia about "Mean time to recovery"
In engineering, the duplication of critical components of a system with the intention of increasing reliability of the system is called redundancy. In many safety-critical systems, such as fly-by-wire aircraft, some parts of the control system may be triplicated. An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are expected to fail independently, the probability of all three failing is calculated to be extremely small. Redundancy may also be known by the terms "Majority voting systems" or "voting logic" . ...more on Wikipedia about "Redundancy (engineering)"
Reliability engineering is the discipline of ensuring that a system will be reliable when operated in a specified manner. Reliability engineering is performed throughout the entire life cycle of a system, including development, test, production and operation. ...more on Wikipedia about "Reliability engineering"
