软件可靠性JM模型完全排错假设的修改

AN IMPROVEMENT ON THE ASSUMPTION OF THOROUGH FAULTS-REMOVAL IN THE JM RELIABILITY MODEL

JM模型是最具代表性的早期软件可靠性马尔可夫过程的数学模型 .其完全排错的假设与软件开发实际不相适合 ,后人虽然提出排错可能引入一个或两个错误的假设 ,但还没有从本质上解决问题 .本文作者对此假设提出自己的观点 .

JM Model is the most represent Markov process software reliability model. Its removing an error thoroughly each time is not fit for practical work. Although some workers have put forth a hypothesis: once remove an error perhaps introduce one or two secondary errors. This method cant resolve the problem thoroughly. In this paper the author put forth a new hypothesis.
