| 摘 要： | CBSD(Component-Based Software Development)已经成为嵌入式软件开发的主流技术。在嵌入式环境下,有大量功能相似的构件,在开发过程中基于QoS的构件选择已成为研究热点。然而这些构件的QoS声明与提供者给出的往往并不一致。为此,提出一种基于修正QoS值的构件选择方法,该方法将QoS信任度作为权重,修正QoS值,再结合模糊逻辑,推理出该构件的综合服务能力。通过嵌入式VOD仿真实验,验证了算法的有效性,保证了构件选择的客观性和准确性。

| Abstract: | Component-based software development(CBSD) has been the predominant technology in embedded software development.Since a lot of components with similar functions can be used in embedded environment,the QoS-based component selection has become a research topic in development process.However the QoS statement is not consistent with the one comes from the providers of these components usually,therefore the paper proposes a component selection approach based on revised QoS value,which takes the trustworthiness o... |
