摘要:

随着Web 服务技术的发展,基于服务模式的软件被广泛应用,包括医疗、教育和公共交通等领域。然而,服务质量QoS的控制是目前服务技术难题之一。在服务组合过程中,针对设计时(Design Time)和运行时(Runtime)的不同服务形态,提出了过设计(Over Design)与欠设计(Under Design)两种偏离需求的服务设计模式,并构建能够约束服务组合的变化空间(Variability Space),实现控制服务质量的目的。通过电子商务的案例展示过设计和欠设计,并对相关偏离情形进行价值分析论证,以论证减少过设计和欠设计的重要性。

关键词: Web服务, 服务组合, 欠设计, 过设计, QoS控制

Abstract:

With the development of the Web service technology, the service mode based software is widely used in the fields of health care, education and public transportation. However, QualityofService (QoS) control is still one of the difficulties in the service technology. In the process of service combination, considering the design-time service and run-time service modes, two service design modes Over Design (OD) and Under Design (UD) are proposed. The variability space that constrains service combination is constructed to achieve the goal of QoS control. We show OD and UD cases in E-commence scenarios and use value based analysis to justify the significance of reducing OD and UD.
