Newtonian and Bergsonian time in technical diagnostics

Testing and reasoning are two main closely related diagnostic activities. Diagnostic testing is realized in Newtonian (short) time while diagnostic reasoning - in (long) Bergsonian time. Both sort of time are used to analyze different kinds of problems in diagnostics and reliability of technical objects. Newtonian and Bersonian time differentiation needs some expert knowledge. In this paper, considerations are based on observation that Newtonian time of diagnostic testing is related to object maintenance (adjustment) and Bergsonian time is related to object is reliability. A significant change of the object’s technical condition (signals or parameters of the state) causes changes of its regulation state (quality indicators change) and the characteristics of reliability. As it is required for the operation and reliability to be always appropriate and permanent, the control should be adjusted to functional needs of the object, and the use should be adapted to the current characteristics of reliability. Therefore, change of the settings of the control device (made during the handling of the object) represents the change of technical condition and state of reliability. It is presumed that, during the operation of a technical object, the selection of the control settings for damaged object is impossible. This fact, when predicted, becomes the basis for the prediction of the object reliability.
