Embodiment 1

[0051] Such as Figure 4 As shown, it is a flow chart of the steps of a system reliability testing method provided by Embodiment 1 of the present invention, which specifically includes:

[0052] Step 101: Configuring multiple reliability sets for the system, each reliability set includes the reliability configured for each node.

[0053] In this step 101, before the reliability test is performed on the system, the test script needs to be pre-configured, and the test time and a plurality of reliability sets used in the test process are set in the test script (the number of reliability sets can be determined according to actual conditions. Test requirements setting), for each reliability set, a random algorithm can be used to configure reliability for each node.

[0054] The embodiment of the present invention does not limit the random algorithm used, and may be any currently available random algorithm, such as inverse transformation method, combination method, convolution meth...

Embodiment 2

[0103] Such as Figure 5 As shown, it is a schematic structural diagram of the system reliability testing equipment in Embodiment 2 of the present invention, which specifically includes the following functional units:

[0104] The configuration unit 201 is configured to configure multiple reliability sets for the system, and each reliability set includes the reliability configured for each node.

[0105] The first determining unit 202 is configured to determine the reliability of the system according to the reliability configured for each node by the configuration unit 201 .

[0106] Wherein: the reliability of the system is the maximum reliability of all paths in the system, and the reliability of each path is the minimum reliability of all nodes in the path.

[0107] The comparison unit 203 is configured to compare the distribution states of multiple reliability levels of the system determined by the first determination unit 202 with the distribution states of multiple pres...

Abstract

The invention discloses a system reliability test method and a system reliability test device. The system reliability test method mainly includes: configuring multiple reliability sets for each node in a system to be tested through a random mode based on a minimal path set method, confirming reliability degrees of the system through a simulation test, comparing a distribution state of a plurality of the confirmed reliability degrees of the system with distribution states of various preset distribution types after all the reliability sets are completely executed, and using the preset distribution type of the distribution state most similar to the distribution state of the reliability degrees of the system as the reliability distribution type of the system. Accordingly, the system reliability test method and the system reliability test device avoid the problems that calculated amount of the reliability degrees of the system is huge due to the fact that complexity of the system is increased, and then complexity of a reliability test is increased in the prior art, and simultaneously avoid uncertainty of a comprehensive test of the system.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a system reliability testing method and equipment. Background technique [0002] In the prior art, system reliability testing is an important part of reliability engineering. The general process of system reliability testing is as follows: first, build a system model for the system to be tested, and determine the logical relationship between the units or subsystems in the system; then, simulate the reliability of the system according to the independent life of each unit or subsystem ; so that the probability of failure can be predicted, and the weak link of the system can be found, so as to improve and enhance the reliability of the system. [0003] However, due to the increasing complexity of the system to be tested, it is difficult to implement traditional life tests that rely on factors such as test time and sample quantity. At present, the Bayes method and the minimum roa...
