Dynamic Reliability of Electronic Control and Security Systems
AbstractReliability of Electronic Devices (ED) is a multimeasure, multifactor group of properties in which traditionally are singled out four (no-failure, longevity, repairability and preservation), and if we add vitality, - five properties. Each group of properties is described by several characteristics, values of which are determined by many factors. Therefore, the general ED reliability model is a trend, not a goal. In the process of decomposition is necessary to seek a rational systematic level, and having rejected inessential factors, their ties, to create conditionally local models. Although production of ED components in Lithuania isn’t increased particularly, for creation of conditions enabling to design reliability of the whole system ,it is necessary to know peculiarities of their reliability. The greatest attention must be paid to the analysis of reliability of typical component, taking into account their short-term electric loads and external dynamic influences. There are investigated control and security reliability peculiarities and their models of electronic system. Also are discussed principles of its rational selection. There are analysed structures of models and trends of their perfection.
