> 中文摘要: 本文在仔细分析了软件故障的物理过程及模型机理后,认为:由于软件故障过程的随机因素太复杂以致于用某一个传统随机过程不足以为软件故障过程建模.传统上采用的马尔可夫非齐次泊松过程模型或二项型式模型只能部分地表述软件的故障行为.若要全面地去表述软件的故障行为,就需要一个补偿随机过程.也就是说本文采用了两个随机函数来为软件故障行为建模.

Abstract:After careful examination of the fundamental mechanics of software failure process, the authors suggested that the random factors in software failure process are too complex to be completely modeled on a single conventional stochastic process model. The generally used Markov or Non Homogeneous Poison Process can partly explain the failure behavior only. To completely explain, a complementary stochastic process is needed. That is to say, two stochastic functions were suggested for modeling the failure behavior of software,hence the name of the model.This thesis presented the work on building such a model.
