Abstract

The invention provides an establishment method of a removal waiting delay considered software reliability growth model based on FSQ (Finite Server Queuing) and relates to the removal waiting delay considered software reliability growth model based on the FSQ. The establishment method aims at solving the problem that the impact on the software reliability of the removal waiting delay and the fault imperfect removal is not considered in the existing software reliability growth model based on the FSQ. The removal waiting delay considered software reliability growth model comprises a mean function model in the fault detection process and a mean function model in the fault correction process. The establishment method comprises step 1, determining the model establishment conditions; step 2, establishing a differential equation according to the conditions and calculating the mean function model of the FSQ-RWD (Finite Server Queuing with Removal Waiting Delay) model in the fault detection process according to the differential equation; step 3, calculating the mean function model of the FSQ-RWD model in the fault correction process according to the fault correction time, the fault removal waiting time and the obtained mean function model in the fault detection process. The establishment method of the removal waiting delay considered software reliability growth model based on the FSQ is used for resting the software reliability.

Description

technical field [0001] The invention relates to an FSQ-based software reliability growth model considering the error-removing delay, in particular to a method for establishing the FSQ-based software reliability growth model considering the error-removing delay. Background technique [0002] Software reliability evaluation is one of the main contents of software reliability engineering research. Accurately assessing and predicting the reliability of software systems, and mastering the reliability status and changing laws of software systems can not only help software testing managers predict the testing time required to achieve specified reliability goals, estimate the number of software residual faults, The maintenance cost of the software and the failure rate of the software system can provide a basis for software release and software testing resource allocation, so that the software can be released on time as planned and meet the reliability requirements of users.
