摘要

本文旨在提出一种系统的方法:(1)指定高级的、基于事件的实时需求;(2)将指定的需求映射到低级的、基于状态的需求。前者表示外部系统行为,后者表示内部系统行为,外部行为在环境事件中指定,内部行为在变量、方法调用等软件实体和操作中指定。该映射可用于软件开发过程和针对安全需求的软件监控。最后,我们将该方法应用于实时安全关键系统——铁路道口控制(RCC)的需求。

Behavioral Specification of Real-Time Requirements
This paper aims to present a systematic method to: (1) specify high-level and event based real-time requirements and (2) map the specified requirements to low-level and state-based one. The former indicates the external system behavior while the latter indicates the internal one, which the external behavior are specified in environment events and the internal behavior is specified in software entities and operations such as variables and method calls. The mapping can be used in software development process and software monitoring against safety requirements. Lastly, we apply our method to requirements of a real-time safety critical system called Railroad Crossing Control (RCC).
