Variability management in software product lines using adaptive object and reflection

The technological advances in electronic and software have been rapidly assimilated by computer systems, demanding new approaches for software and systems engineering to provide reliable products, under well-known quality criteria. In this context, requirements engineering has a strategic role in project development. Problems in the elicitation activity contribute to producing poor, inadequate or even non-existent requirements that can cause mission losses, material or financial disasters, premature project termination or promote an organizational crisis. This thesis introduces the elicitation process for dependability goals, called ELICERE, applied to critical computer systems based on a goal-oriented requirement engineering technique, called i*, and the safety engineering techniques HAZOP and FMEA, which will be applied for the identification and analysis of operational risks of a system. After creating the system models using i* diagrams, they are analyzed through guidewords based on HAZOP and FMEA, from which goals related to dependability are extracted. Through this interdisciplinary approach, ELICERE promotes the identification of goals that meet the quality requirements, related to dependability for critical systems, still in the project conception phase. The case study approach is based on a qualitative and descriptive single-case, using a computer system project of a hypothetical launching rocket, called V-ALFA. The ELICERE application in this space project intends to improve the requirement engineering activities in the computer system of the Brazilian Satellite Launch Vehicle, and also a way to explain how the ELICERE process works.
