Embodiment 1
[0052] A method for reliability modeling of open source software based on the introduction of faults in the troubleshooting process, comprising the following steps:
[0053] (1) Put forward model assumptions:
[0054] Open source software fault detection process and fault troubleshooting process obey non-homogeneous Poisson process;
[0055] The number of instantaneously detected faults is directly proportional to the number of remaining faults in open source software;
[0056] The number of faults corrected instantaneously is proportional to the number of faults detected by open source software but not removed;

The invention belongs to the technical field of open source software reliability models, and particularly relates to an open source software reliability modeling method for introducing faults based ona debugging process. The method comprises the following steps: (1) proposing a model hypothesis; (2) establishing a differential equation; and (3) establishing an open source software fault detectionreliability model. According to the method, on the basis of fully considering that time delay exists between actual open source software fault detection and fault removal, a corresponding open sourcesoftware reliability model is established by considering the situation that faults are possibly introduced when the faults are removed. Due to the fact that the situation that faults are possibly introduced when the faults of the open source software are removed is considered, the established ground open source software reliability model better conforms to the actual fault detection and fault removal change process, and the assumption of establishing the ground open source software reliability model is more reasonable and credible.
Description
technical field [0001] The invention belongs to the technical field of open-source software reliability models, and in particular relates to an open-source software reliability modeling method based on the introduction of faults in the troubleshooting process. Background technique [0002] In the modern information society, the application of software is more and more extensive. Not only is software being coded in ever-increasing scale and functionality, but the way it is developed has changed a lot. For example, open source software development methods that have become popular in recent years. The development of open source software is different from traditional closed source software development. Raymond called the development model of open source software Bazaar (bazaar), and traditional closed source software development as Cathedral (cathedral). Additionally, testing of open source software is done by developers, community volunteers, and users. Due to the open and ...
