Software reliability growth model considering environmental difference
Hang Lei · Journal of Computer Applications · 2011
The failure intensity function will be misjudged in Software Reliability Growth Model(SRGM),because of the difference between the testing environment and the user environment.A logarithmic Poisson model considering environment factor was proposed,which was based on the M-O logarithmic Poisson execution time model,the representative of Musa execution-time models.It can represent the change law of the failure intensity function better,and the parameter estimation equations had been provided.The experimental results based on the failure data sets show that the proposed model has better fitting curve than some of other models.
