• 00:1900:19, 23 July 2024 diff hist −78 Reliability engineering →Definitions: removed all references to time. time is part of the 'stated conditions'. it may or may not be required. for example, the reliability of a crane cable to lift a load is related to the statistical distribution of the spread of the cable's strength, versus the load's distribution of varying weight.

• 00:1600:16, 23 July 2024 diff hist −39 Reliability engineering →Overview: the definition is consistently incorrect that states that reliability must involve a time component. ive made several edits now trying to remove the implied meaning that reliability must be related to time, which is incorrect.

• 00:1400:14, 23 July 2024 diff hist −33 Reliability engineering removed the example which implies that reliability is only related to probability of success at time t. this is not correct as it does not need a time element. time is commonly used, but many instances occur where it is not. Practical Reliability Engineering textbook by 'O'Connor has many examples of reliability calculations that do not use a time element. Tag: Visual edit
• 00:1100:11, 23 July 2024 diff hist +85 Reliability engineering changed the definition of reliability as it was incorrect. Reliability does not need a time component in order to be evaluated. ASQ have the correct definition which states that it may be time related, but does not need to be so. Reliability without a time component is often used in stress/strain calculations but also signal/noise and many other applications. Tag: Visual edit
