| 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. |
