Automatic Analysis of System Tolerance Based on Error Graph
LI Ying-hong · Systems engineering and electronics · 2003
In order to realize the automatic analysis of the tolerance in a complex system, a method based on an error graph is put forward.The direct error transfer between system parameters is described by the connection of the nodes in an error graph. The automatic analysis of the system's tolerance is performed by means of the iterative seeking method. And a typical example is presented . It proves the method could process the nonlinear transfer and networking relevancy problems of system parameters. The method effectively solves the problem of the tolerance automatic analysis of the nonlinear system whose state changes greatly.
