Enquadramento
One of the major challenges related to self-adaptive software systems is the provision of assurances that the system is resilient against changes that may occur either in the system or its environment. These assurances should be based on disparate sources evidence that collectively justify that the system is able to attain the specified levels of resilience.
A recent proposal in this line concerns an architecture-based approach that evaluates by comparison the adaptation mechanisms of a self-adaptive software system, relying on the identification of representative environmental and system changeloads (i.e., sequence of changes) used in the run-time stimulation of the system.
Objetivo
Demonstrate the effectiveness of the aforementioned approach in the context of Rainbow and DCAS, a case study on self-adaptation developed by the University of Coimbra in cooperation with Critical Software.
Plano de Trabalhos - Semestre 1
1. In-depth analysis of the architecture of the Rainbow Framework and DCAS System (1.5 months).
2. Identification of environmental and system sources of potential changes that may impact the different business concerns considered in DCAS (3 weeks).
3. Ellaboration of scenarios for testing system response (1 month).
4. Experimentation design (1 month).
Plano de Trabalhos - Semestre 2
1. Code instrumentation and implementation required for running the experiments (2 months).
2. Experimentation (2 months).
3. Writing of final report (2 months).
*The activities described in the different semesters may overlap in time.
Condições
