Study of fault diagnosis model for SCP software

The requirement is more and more severe for reliability of SCP software in intelligent network on the current communication network, and the fault diagnosis of SCP software becomes one important topic in studies of intelligent network, in which one appropriate diagnosis model is more important.The characters of the fault are analyzed, including the characters of the result, the causation of the fault, and the corresponding relation between the causation and result.Then one new fault diagnosis model based on the Belief network is presented and the rules and the designs of the model structure are defined, such as node, side, matrix and layer.Now the model is used in the fault diagnosis of the SCP software and is being consummated.
