摘要： 实时系统通常有严格的服务质量约束导致其维护和演化困难，针对该问题，提出一种面向方面的实时系统开发方法。该方法从实时系统的功能需求中分离出非功能需求，建立相应功能模型和非功能模型，生成相应组件和方面。应用结果表明，该方法可根据实际应用环境组成可配置的实时系统，组成的实时系统具有较低的开发复杂性，较高的可重用性和灵活性。

Abstract: Real-time system commonly has rigorous service quality restriction to lead its hard safeguard and evolutionary. Aiming at the problem, this paper proposes an aspect-oriented development method for real-time system. This paper separates the system non-functional requirements from functional requirements, builds relevant functional model and non-functional model according to these requirements, and generates relevant components and aspects. Application results show that this method can compose configurable real-time system according to realistic application requirements, composed real-time system has lower development complexity, higher reusability and flexibility.

Key words: aspect-oriented, real-time system, Quality of Service(QoS)
