A model-based approach to self-adaptive software

The authors´ model based approach to self adaptive software systems uses domain specific models and components to restore flexibility and adaptability to software systems running in dynamic environments. The model-integrated approach to self adaptive software, decomposes the problem into two major issues: the issues of representation and that of the reconfiguration mechanism. The goal of the work is to facilitate a performance→evolution→architecture modification→modified performance cycle in which the application´s performance is continuously monitored, with the results used to modify the architectural model. The modification is then followed by a partial or complete regeneration of the executable system. We have implemented and tested some aspects of our approach in applications; other aspects are part of our ongoing investigation in various research projects
