How to Estimate MTBF of Software
Gong Yun-zha · 2001
The number of initial defects number No, MTBF, defect exposure rate I and success rate of running q are basic parameters of software reliability of which MTBF is the most important one. Traditionally, there are two methods to compute MTBF, one is to compute the average interval between two successive faults and the other is to estimate MTBF from software reliability models. But the former spends a lot of time and the latter is not accurate. This paper proposes a new method to estimate MTBF according to failure rate and the results demonstrate that this is a practical method
