一种基于失效费用划分的穿戴计算机软件可靠性模型

A Software Reliability Model Based on Failure Cost Partition for Wearable Computers

根据故障的严重程度对软件系统中潜伏的故障进行了类型划分 ,并利用传统的G O模型建立了一个基于失效费用划分的软件可靠性增长模型 无线网络使穿戴计算机的性能得到了很大的提升 ,根据是否会严重影响穿戴计算机的网络通信能力 ,将其软件系统的故障分为两类 :①一般故障 ,不影响或较小影响系统的网络通信 ;②通信故障 ,严重影响甚至阻断系统的网络通信 利用前面建立的软件可靠性增长模型 ,建立了一个穿戴计算机软件系统可靠性增长模型 。

All faults hidden in the software can be divided into different types according to the loss it maybe make. A new software reliability growth model specific for different types of faults is proposed based on the traditional G-O model. The wireless communication technology improves the performance of the wearable computer greatly. The software faults of the wearable computer can be divided into two types by their influence on communication: ① common faults,faults which affect slightly or don't affect communication;② communication faults,faults which affect terribly or interrupt communication. In order to evaluate the software reliability of a wearable computer,an SRGM is established based on the model just built and a group of data is used on it.
