Research of Software Reliability Model after Software Released
Shen Yuan-long · Computer Technology and Development · 2011
Because the assumption of P-B model raised by Pankaj Jalote and Brendan Murphy was too rigorous and the applicable scope was narrow,a reliable model based on the publication of software was brought up.This model not only considered the effect caused by the users of the original P-B model,but also took the influences of modifying errors of software itself by edition upgrading and patching into account,by taking the effect into the decay factor of the mode,modifying the decay factor of the original model and estimating parameters of the new model by least square method.At last,the simulation experiment proved that the improved new model was more accurate on calculation and more suitable to the real changes of the amount of parameters of software failure.
