Real-time Software Reliability Model Based on Task Modular

摘要: 根据实时多任软件的特征和各任务所占系统时间的非均匀分布,以任务模块为基本测试单元,提出一种实时多任务软件可靠性评价模型。由于任务周期、任务切换方式、切换频率以及任务故障率等基本参数易于分析和测试,因此该模型具有良好的可实现性和可扩充性,为实时多任务软件的可靠性评价开辟了一条新途径。

Abstract: According to the feature of real-time multi-tasks software systems and nonhomogeneous distributed that different task consume system time,taking task modular as basic testing unit,this paper presents a evaluation model of real-time multi-task software systems.Since the parameters,for example task period,task switch method and switch frequence are easy to analyse and test,the model possesses good extensibility and feasibility.This modeling method provides a new way for the reliability evaluation of real-time multi-task software.
