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。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 of QoS as the weight,revises QoS value and then reasons the comprehensive service capability for the component in conjunction with fuzzy logic.Embedded VOD simulation experiments verify the effectiveness of our approach and guarantee the objectivity and accuracy of the component selection.
