“…In our previous work, we investigated DSPL verification, context variability modeling, and issues related to the implementation of DSPL. Hence, we have proposed a DSPL model checking technique [37] and feature model language for DSPL that may specify constraints among context [38]. Also, we evidenced in our previous study [39] that DSPL should also deal with evolution in terms of functionality and adaptation capabilities when the demand arises for new requirements for existing products or new configurations.…”

“…An expressive and correct model for DAS development is a first-class concern. In this section, we present the steps for modeling DAS using the extended Context-aware Feature Modeling (eCFM) technique, which was proposed in our previous study [38]. The eCFM technique consists of an extension of the Context-Aware Feature Model [60] to deal with constraints among contexts.…”

Software engineers have adopted the Dynamic Software Product Lines (DSPL) engineering practices to develop Dynamically Adaptable Software (DAS). DAS is seen as a DSPL application and must cope with a large number of configurations of features, Non-functional Requirements (NFRs), and contexts. However, the accurate representation of the impact of features over NFRs and contexts for the identification of optimal configurations is not a trivial task. Software engineers need to have domain knowledge and design DAS before deploying to satisfy those requirements. Aiming to handle them, we proposed an approach of Trade-off Analysis for DSPL at design-time, named ToffA-DSPL. It deals with the configuration selection process considering interactions between NFRs and contexts. We performed an exploratory study based on simulations to identify the usefulness of the ToffA-DSPL approach. In general, the configurations suggested by ToffA-DSPL provide high satisfaction levels of NFRs. Based on simulations, we evidenced that our approach aims to explore reuse and is useful for generating valid and optimal configurations. In addition, ToffA-DSPL enables software engineers to conduct trade-off analysis, evaluate changes in the context feature, and define an adaptation model from optimal configurations found in the analysis.
