摘要：Software Product Line has proved to be an effective approach to benefit from software reuse.
Configuration management, an integral part of any software development activity, takes on a special significance in
software product line context. This is due to the special property of software product line, in which the core assets
are shared by all products. In this paper, we compare the existing configuration management models and analyze the
artifacts that need to be configuration managed in software product line. We then present an evolution-based
configuration management model for software product line, in which, the configuration management is divided into
two domains, the production domain and the product domain. In this model, the evolution propagation of corrective
changes and enhancement changes on different configuration artifacts follow different paths. The advantages and the
constraints of this model are also discussed.
