摘要:

实时的系统是一种计算系统,在这种系统中,满足实时系统的要求对于实时系统的正确性至关重要。因此,如果对这些系统的实时的需求理解和验证不足,其结果可能是灾难性的,并在开发的早期阶段导致无法补救的项目失败。针对并发实时的系统在需求规格说明阶段早期检测死锁的问题,提出了一个简单的概念验证原型,将基于拓扑的需求规格说明和技术结合起来.这些努力集中在将消息序列图场景的形式化表示集成到Fajstrup等人的死锁检测算法中,基于几何学和代数拓扑学。

英文摘要:

Real-time systems are computing systems in which the meeting of their requirements is vital for their correctness. Consequently, if the real-time requirements of these systems are poorly understood and verified, the results can be disastrous and lead to irremediable project failures at the early phases of development. The present work addresses the problem of detecting deadlock situations early in the requirements specification phase of a concurrent real time system, proposing a simple proof-of-concepts prototype that joins scenario-based requirements specifications and techniques based on topology. The efforts are concentrated in the integration of the formal representation of Message Sequence Chart scenarios into the deadlock detection algorithm of Fajstrup et al., based on geometric and algebraic topology.
