Fault Characteristic Analysis of LRE
It is known that the faults will occur in the LRE with the increase of the service time. The high reliability of LRE represents that the system may fulfill the task successfully with very low probability to go wrong. However, the structure defect and parameter mismatch may accelerate the development speed of the LRE to the design limitation and may make the system appear failures ahead of the design limitation. It is shown that the reason of the faults may be deduced by the performance of the fault, since any fault has its own expression.
