Time-Dependent Error-Detection Rate Model for Software Reliability and Other Performance Measures
Amrit L. Goel, Kazu Okumoto · IEEE Transactions on Reliability · 1979
This paper presents a stochastic model for the software failure phenomenon based on a nonhomogeneous Poisson process (NHPP). The failure process is analyzed to develop a suitable meanvalue function for the NHPP; expressions are given for several performance measures. Actual software failure data are analyzed and compared with a previous analysis.
