specific Embodiment approach 1

[0026] Specific implementation mode one: combine figure 1 with figure 2 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 testing process includes a fault detection process and a fault elimination process. An integration testing troubleshooting strategy links these two stochastic processes.

[0027] 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 correspondin...

specific Embodiment approach 2

[0091] Specific implementation mode two: combination Figure 3 to Figure 19 This embodiment is described. The first difference between this embodiment and the specific embodiment lies in the experimental analysis of the simulation method based on HFSQM. The architecture of the application is as image 3 shown.

[0092] Analysis of simulation process without considering the limitation of debugging resources

[0093] Use the failure rate of Goel-Okumoto software reliability growth model to describe the failure behavior of each component in the application. Then the failure rate of component i is where α i Denotes the expected value of the total number of faults that may eventually be detected from component i, b i Indicates the detection rate of each fault, t i Indicates the cumulative execution time of component i. Without loss of generality, assume that all components in the application satisfy a i =20.05,b i =0.0057, the execution time of the component is one time u...

Abstract

The invention discloses a component software reliability analysis method capable of considering limitation of debugging resources based on an HFSQM (Hybrid Finite Server Queuing Model), which relates to software reliability analysis methods, and overcomes the defects that infinite debugging resources are impossible in practical application and the newly detected failures have to wait in a queue when all the debugging staffs are busy. The method is realized by the following three steps of: resource allocation, failure detection and failure recovery. The resource allocation step is to allocate appropriate resources for the failures waiting for the debugging resources in the HFSQM; the failure detection process is used for executing an integration test on the entire application based on an operating profile of the component software application; and the failure recovery process is used for recovering the failures occupying the debugging resources in the HFSQM. Thus, a basis for software release and rational configuration of test resources is provided, the software can be punctually released on schedule, user demands on the reliability can be satisfied, and the total cost of the software is lowered. So, an HFSQM-based simulation method has important directive significance for component software tests and further for software marketing decisions.

Description

technical field [0001] The invention relates to a software reliability analysis method Background technique [0002] The currently proposed component software reliability analysis model ignores the troubleshooting process in component software integration testing, and proposes a HISQM model to model and analyze the troubleshooting process. The HISQM model assumes that the number of troubleshooting personnel is infinite, and that detected faults can be assigned to troubleshooting personnel immediately. This assumption does not take into account the limitations of troubleshooting resources. In practice, it is impossible to have unlimited troubleshooting resources. Due to cost and budget reasons, the number of troubleshooting personnel is often limited and strictly controlled. When all troubleshooting crews are occupied, newly detected faults must be queued. Contents of the invention [0003] In order to solve the problem that it is impossible to have unlimited troubleshoo...
