A Software Reliability Growth Test Based on Duane Model
He Jing · Journal of Institute of Command and Technology · 2005
The engineering background and technique of the software reliability growth test based on Duane model is introduced in this paper. First the mathematical expression of Duane model is de- scribed. Then a Duane curve combined with original reliability data of an aerospace TTC system is drawn. Using the least-squares-error(LSE) means the parameters of Duane model are estimated and an amendable Duane curve is drawn. Finally we calculate the system software MTBF and A value and compare them with prediction value. Consequently it is proved that Duane model is correct and reason- able for software reliability growth test.
