specific Embodiment approach 1
[0055] Specific implementation mode one: combine figure 1 This embodiment is described. The component software integration test in this embodiment refers to the process of assembling all the components in the application for testing, and all the components in the application work together. As tests are performed, faults are continuously discovered and eliminated, and the software application experiences an increase in reliability. The integration testing process includes the fault detection process and the troubleshooting process. An integration testing troubleshooting strategy links these two stochastic processes.
[0056] During the integration testing process, the troubleshooting activities are organized according to the troubleshooting strategy. Troubleshooting strategy According to the actual development characteristics and budget and schedule requirements, the troubleshooting resources are reasonably allocated, and the detected faults are assigned to the corresponding...

The difference between this embodiment and the specific embodiment 1 lies in the experimental analysis of the HISQM queuing model. HISQM model parameter setting, the figure 2 The architecture model of the component software application is brought into the improved additive model, and the steady-state probability vector of the component in the application is calculated as

Abstract
The invention relates to a method for analyzing reliability of component software considering a failure recovery process based on an HISQM (Hybrid Infinite Server Queue Module), which relates to a method for analyzing the reliability of software and overcomes the defect that in a traditional module and method based on an architecture, only a failure detection process is considered, while the failure recovery process is ignored. Based on a queuing theory, the HISQM is used for modeling the failure recovery process in a component software integration test. The component software integration test process comprises the failure detection process and the failure recovery process. A debugging strategy of the integration test combines the two random processes. The HISQM is formed by a plurality of independent ISQ (Infinite Server Queue) systems, and each ISQ system is used for describing a recovery behavior of component failure distributed to the system according to the debugging strategy. An arrival process and a leaving process of the HISQM are analyzed to be respectively corresponding to the failure detection process and the failure recovery process in the component software integration test. An NHPP (Non-Homogeneous Poisson Process) software reliability growth module is used for modeling the failure detection process of the component software.
Description
technical field [0001] The invention relates to a software reliability analysis method. Background technique [0002] In the reliability analysis of component software testing phase, the traditional architecture-based models and methods, in order to make the model easy to solve, often only consider the fault detection process in the test, ignoring the fault elimination process. A common assumption is to assume that a detected fault can be fully repaired immediately or with negligible troubleshooting time. This assumption oversimplifies the integration testing process of component software applications and does not correspond to reality. [0003] In the past, researchers have discussed how queuing methods can be used to explain debugging behavior in software testing. Dohi et al put the two types of NHPP models, finite fault and infinite fault, into a unified modeling framework, introduced an ISQ model to describe software troubleshooting behavior, and explained that the sof...
