摘要： 根据实时多任务软件的特征和各任务所占系统时间的非均匀分布,以任务模块为基本单元,提出一种实时多任务软件可靠性评价模型.该模型所需参数易分析和计算,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.

关键词: 可靠性, 实时软件, 评价模型, 故障率

Abstract: By taking the task modulars as a basic testing unit, an evaluation model of the real-time multitasking software is presented in this paper. Since the parameters in the model are easy to be analysed and tested, this model is useful in evaluating the reliability of the real-time multitasking software.

Key words: real-time software, evaluation model, reliability, fault rate
