A systematic classification of requirements engineering approaches for adaptive systems

Requirements Engineering for Adaptive Systems (REAS) is a wide-open research area that aims to improve the adaptation of the systems according to the requirements known (adaptability) or newly detected (adaptivity). While existing work proposed methodologies to deal with the adaptivity problem, few of them have classified and evaluated these proposals in order to give insight for system development in application domains such as Smart City Operations (SCO's). In this paper, we investigate the modeling methodologies, Requirements Engineering (RE) activities, and application domains based on relevant papers that tackled REAS in the literature. To this end, we conduct a systematic literature review by searching relevant papers and extracting data in order to answer specific research questions. We provide an updated review of the state of the art, supporting researchers to better understand trends in REAS in general and SCO's in particular.
