由于许多软件系统已经转变为Web服务，因此Web服务的演化变化正成为一个重要问题。要了解更改影响服务的方式，我们必须确定系统中将受更改影响的部分，并检查它们是否有额外的影响。本文提出了一种基于服务依赖的影响分析模型。重点研究了服务依赖图模型、服务依赖关系和关系矩阵。通过对矩阵的移位和计算，分析服务演化的依赖性和影响，确定服务演化的数量。此外，我们还提出了一种服务变更注释和服务演化过程的方法。总之，这些工作为服务演进的自动管理、控制和评估提供了基础。
As many software systems have been turned as Web services, the evolutionary changes of Web services are becoming an important issue. To understand the way in which the change affects the services, we must ascertain parts of the system that will be effected by the change and examine them for additional impacts. In this paper, we propose an impact analysis model based on service dependency. In particular, the service dependency graph model, service dependency and the relation matrix are examined. Based on the shift and calculation of the matrix, the dependency and impact of the service evolution can be analyzed and its quantity can be ascertained. Furthermore, we also represent an approach for service change annotation and for service evolution process. Overall, these works provide a foundation for the automatic management, control, and evaluation of service evolution.
