An Incremental Method for the Design of Feature-Oriented Systems

. Telecommunication systems involve many optional features which cannot be combined according to an obvious definition because they can interact together in an unpredictable way. In order to find the best way to combine features, a major di#culty is to foresee or to discover when a feature can disrupt an another one. Once such an interaction has been analysed, it still remains to define the best combination between the involved features. As this decision is purely subjective, we model the design of feature-oriented systems as an iterative process controlled by an expert judgement: all along the process, the expert increases his knowledge about the system under design and thus, may revise the feature integration design w.r.t. his expertise ... until he decides to accept the current feature integration as conform to his ideal view of the system. We propose to jointly adjust the description of a system built by integrating features and the expected properties on the global system all alon..
