  2. Stress–strength analysis - Wikipedia

    en.wikipedia.org/wiki/Stress–strength_analysis

    Stress-Strength Analysis is a tool used in reliability engineering. Environmental stresses have a distribution with a mean ( μ x ) {\displaystyle \left(\mu _{x}\right)} and a standard deviation ( s x ) {\displaystyle \left(s_{x}\right)} and component strengths have a distribution with a mean ( μ y ) {\displaystyle \left(\mu _{y}\right)} and a ...

  3. Parts stress modelling - Wikipedia

    en.wikipedia.org/wiki/Parts_stress_modelling

    Parts stress modelling is a method in engineering and especially electronics to find an expected value for the rate of failure of the mechanical and electronic components of a system.

  4. CAIDI - Wikipedia

    en.wikipedia.org/wiki/CAIDI

    The Customer Average Interruption Duration Index (CAIDI) is a reliability index commonly used by electric power utilities. [1] It is related to SAIDI and SAIFI, and is calculated as

  5. Mean time between failures - Wikipedia

    en.wikipedia.org/wiki/Mean_time_between_failures

    The Mil-HDBK-217 reliability calculator manual in combination with RelCalc software (or other comparable tool) enables MTBF reliability rates to be predicted based on design. A concept which is closely related to MTBF, and is important in the computations involving MTBF, is the mean down time (MDT). MDT can be defined as mean time which the ...

  6. Reliability prediction for electronic components - Wikipedia

    en.wikipedia.org/wiki/Reliability_prediction_for...

    A prediction of reliability is an important element in the process of selecting equipment for use by telecommunications service providers and other buyers of electronic equipment, and it is essential during the design stage of engineering systems life cycle. [1] Reliability is a measure of the frequency of equipment failures as a function of time.

  7. SAIDI - Wikipedia

    en.wikipedia.org/wiki/SAIDI

    The System Average Interruption Duration Index (SAIDI) [1] is commonly used as a reliability index by electric power utilities.SAIDI is the average cumulative outage duration for each customer served, and is calculated as:

  8. Cronbach's alpha - Wikipedia

    en.wikipedia.org/wiki/Cronbach's_alpha

    There are a few alternatives to automatically calculate SEM-based reliability coefficients. R (free): The psych package [50] calculates various reliability coefficients. EQS (paid): [51] This SEM software has a function to calculate reliability coefficients. RelCalc (free): [3] Available with Microsoft Excel.

  9. Rainflow-counting algorithm - Wikipedia

    en.wikipedia.org/wiki/Rainflow-counting_algorithm

    Rainflow counting identifies the closed cycles in a stress-strain curve. The rainflow-counting algorithm is used in calculating the fatigue life of a component in order to convert a loading sequence of varying stress into a set of constant amplitude stress reversals with equivalent fatigue damage.
