| 中文摘要: |
| 借助于软件模块化和概率论的基本思维方法,对软件可靠性进行估计,将系统看成是由多个模块所组成的整体,先计算各个模块的寿命函数,在此基础之上根据模块和系统之间的逻辑关系得到软件系统的寿命函数,再通过模块寿命函数的不同取值获得软件寿命的多种仿真算法.该方法不仅适用于软件可靠性的预测,也可用于计算软件平均持续工作时间,为同类问题的解决提出了-种新的思路. |
| 英文摘要: |
| The paper presents the correct degree which is executed under users′ requirement and designed object.Based on probability and modularization of software,we can estimate the reliability of software in the other way,treat the system as a whole including several models.We first calculate the life of the modules function,and then gain the life function of software systems on the basis of the logic of relations between the models and systems,from which we can access to a variety of simulation algorithms.This method can not only apply to the forecast of software reliability,but also be used to calculate the average duration of software.Additionally,it presents a new way for the settlement of the similar issue. |
