DSPL approaches provide means for modelling variability as well as a configuration process for binding variability according to runtime changes in the context and/or non-functional requirements (NFRs). However, taking contexts and NFRs into account may result in multiple and, sometimes, conflicting possible configurations. Most of DSPL approaches do not provide means for prioritizing possible configurations in order to select one of them, and those that provide, do not take into account the NFRs’ priority for the current context. [Objective] In this work, we propose a Requirements Engineering (RE) approach for DSPL, ConG4DaS (Contextual Goal models For Dynamic Software product lines), which provides: (i) models for capturing variability with goals, NFRs, contexts and the relationship between them; and (ii) a configuration process that takes contexts, NFRs and their priority and interactions into account. [Method] We have used simulation based assessment to compare ConG4DaS with another approach with respect to the satisfaction level of the highest priority softgoal. We simulated several different contexts of two DSPL examples and compared the configurations generated by both approaches. We also performed a survey, using an online questionnaire, with RE and DSPL researchers to evaluate ConG4DaS perceived usefulness. [Results] In the simulation based assessment, in the configurations selected by ConG4DaS the number of positive contributions and the difference between the numbers of positive and negative contributions to the highest priority softgoal are greater than in the randomly selected configurations of the other approach. However, when comparing ConG4DaS configurations to the manually selected configurations of the other approach, there is no significant difference between them. In the survey, both groups of researchers (RE and DSPL) perceived ConG4DaS as useful for modelling and configuring DSPL variability. But the RE group gave more positive answers than the DSPL group.CNPq[Contexto] Linhas de Produto de Software Dinâmicas (LPSDs) são LPSs em que a configuração ocorre em tempo de execução. Abordagens para LPSD proveem meios para modelar variabilidade, além de um processo de configuração para amarrar a variabilidade de acordo com mudanças no contexto e/ou requisitos não-funcionais (RNFs) em tempo de execução. Contudo, levar em conta contextos e RNFs pode resultar em múltiplas configurações possíveis, às vezes conflitantes. A maioria das abordagens para DSPL não possuem uma maneira de priorizar essas possíveis configurações para poder selecionar uma delas, e aquelas que possuem não levam em conta a prioridade dos RNFs para o contexto atual. [Objetivo] Neste trabalho, propõe-se uma abordagem de Engenharia de Requisitos (ER) para LPSDs, chamada ConG4DaS (do inglês, Contextual Goal models For Dynamic Software product lines), que provê: (i) modelos para capturar variabilidade usando objetivos, RNFs, contextos e seus relacionamentos; e (ii) um processo de configuração que leva em conta contextos, RNFs e suas prioridades e interações. [Método] Foi feita uma avaliação baseada em simulações para comparar ConG4DaS com outra abordagem, com respeito ao nível de satisfação do softgoal prioritário. Foram simulados vários contextos diferentes de dois exemplos de LPSD e comparou- se as configurações geradas pelas duas abordagens. Também foi realizada uma pesquisa, usando questionário online, com pesquisadores de ER e LPSD para avaliar a utilidade percebida de ConG4DaS. [Resultados] Na avaliação baseada em simulações, o número de contribuições positivas para o softgoal prioritário e a diferença entre o número de contribuições positivas e negativas para o mesmo softgoal eram maiores nas configurações escolhidas por ConG4DaS do que nas configurações aleatoriamente selecionadas da outra abordagem. Contudo, quando comparam-se as configurações de ConG4DaS com as da outra abordagem que foram selecionadas manualmente, não há diferença significativa entre elas. No questionário, os dois grupos de pesquisadores (tanto de ER, como de LPSD) perceberam ConG4DaS como útil para modelagem e configuração da variabilidade de LPSD. Entretanto, no grupo de ER houve mais respostas positivas do que no grupo de LPSD.engUniversidade Federal de PernambucoPrograma de Pos Graduacao em Ciencia da ComputacaoUFPEBrasilAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessEngenharia de SoftwareEngenharia de RequisitosModelo de ObjetivoSistemas AdaptativosContextual Goal Models for Dynamic Software Product Linesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisdoutoradoreponame:Repositório Institucional da UFPEinstname:Universidade Federal de Pernambuco (UFPE)instacron:UFPETHUMBNAILTESE Gabriela Guedes de Souza.pdf.jpgTESE Gabriela Guedes de Souza.pdf.jpgGenerated Thumbnailimage/jpeg1336https://repositorio.ufpe.br/bitstream/123456789/29392/5/TESE%20Gabriela%20Guedes%20de%20Souza.pdf.jpg8d1a14c9279abd2c50122c9a7eb2afbcMD55ORIGINALTESE Gabriela Guedes de Souza.pdfTESE Gabriela Guedes de Souza.pdfapplication/pdf9601022https://repositorio.ufpe.br/bitstream/123456789/29392/1/TESE%20Gabriela%20Guedes%20de%20Souza.pdfd3ce1702508137924355e542ccdb2f63MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
