ABSTRACT
The concepts of system and components utilized in the theory of reliability depend on many aspects. Instead, elements or components of a system are bars, beams, plates, cables, panels, blocks, and so on. If stresses in all elements are equal, then probability density function becomes: Consider, for example, a system consisting of 25 components. As a result, reliability can be estimated by treating such systems as a series of connected elements. A system is usually an aggregate of elements joined together for specific operations while each element is the simplest part of the aggregate. The concepts of system and components utilized in the theory of reliability depend on many aspects. The same object can play the role of a system or an element depending on the problem’s specifics. The role of a system can be played by a population of structures intended for performing specific function(s) in ensemble. Buildings, aircraft, ships, vehicles, so on are typical examples of structural systems.
