摘　　要：本文对软件的复杂性、强度及重要度进行了分析,针对实时多任务软件的具体特点,提出了一种基于任务模块的软件可靠性指标分配模型以及计算方法。针对某一组合导航系统应用软件,采用上述模型进行软件可靠性指标分配计算。结果表明,在保证系统可靠性的前提下,能够实现各子任务可靠性指标的合理分配。The complexity, intensity and significance of software are analyzed in this paper. Reliability allocation of objectives model and algorithmic method which based on task module are presented focus on the characteristics of real-time multitask software. Aiming at this integrated navigation system application software, the model which is mentioned above is distributed and calculated. The result shows that, the reasonable distribution of subtasks reliability index can be realized under the condition of available system reliability.
