Redundancy based design by event oriented analysis

The paper investigates a lifetime service of mechanical objects put through failures in order to illustrate the convenience of uncertainty modelling and redundancy based design by event-oriented system analysis (EOSA) in engineering. The numerical example presented in the paper provides results and comparisons with the traditional approach to the redundancy assessment based on reserve strength. It is demonstrated how EOSA identifies the system configuration and evaluates the service performance of potentially redundant objects in case of component failures and load redistribution. In the conclusion, EOSA appears to be an appropriate method for treating systems acting under uncertain conditions, and useful in the improvement of redundant system design in engineering.
