While Service-Oriented Architecture helps the realization of Software Product Line, the current practice of manual composition of service components has become a bottleneck for the automation of customized software production. The web service-based applications are increasing in the present days. The use of web services for the development of the software with the idea of product line is a new feature. This approach not only uses clientsu27 requirements for the identification of candidate services, but also takes sensitivity into consideration when deciding the most suitable ones for a particular custom-made software system. This enhancement of service selection and composition leads to the development of an enhanced framework of service integration life-cycle, whose operation is presented in a new algorithm in this thesis. In addition to details of the framework, a case study is also included to examine the process of candidate identification, sensitivity analysis, service selection, and system composition for a customized online shopping system.
