Most of these strategies use an UML (Unified Modeling Language)-based model specification. Despite its wide application, the UML-based model specification has some limitations such as the fact that it is essentially graphic, presents deficiencies regarding the precise description of the system architecture semantic representation, and generates a large model, thus hampering the visualization and comprehension of the system elements. In contrast, architecture description languages (ADLs) provide graphic and textual support for the structural representation of architectural elements, their constraints and interactions. This thesis introduces ArchSPL-MDD, a model-driven strategy in which models are specified and configured by using the LightPL-ACME ADL. Such strategy is associated to a generic process with systematic activities that enable to automatically generate customized source code from the product model. ArchSPLMDD strategy integrates aspect-oriented software development (AOSD), modeldriven development (MDD) and SPL, thus enabling the explicit modeling as well as the modularization of variabilities and crosscutting concerns. The process is instantiated by the ArchSPL-MDD tool, which supports the specification of domain models (the focus of the development) in LightPL-ACME. The ArchSPL-MDD uses the Ginga Digital TV middleware as case study. In order to evaluate the efficiency, applicability, expressiveness, and complexity of the ArchSPL-MDD strategy, a controlled experiment was carried out in order to evaluate and compare the ArchSPL-MDD tool with the GingaForAll tool, which instantiates the process that is part of the GingaForAll UML-based strategy. Both tools were used for configuring the products of Ginga SPL and generating the product source code / Estrat?gias dirigidas a modelos t?m sido usadas para facilitar a customiza??o de produtos no contexto de Linhas de Produtos de Software (LPS) e gera??o de c?digo fonte desses produtos derivados atrav?s do gerenciamento de variabilidades. A maioria dessas estrat?gias faz uso da especifica??o de modelos baseados em UML (Unified Modeling Language), que apesar de ser amplamente aplicada, possui algumas limita??es por ser essencialmente gr?fica, apresentar defici?ncia em descrever precisamente a sem?ntica da representa??o da arquitetura do sistema e gerar um modelo extenso, o que dificulta a visualiza??o e compreens?o dos elementos do sistema. J? as linguagens de descri??o arquiteturais (ADLs) oferecem suporte textual e gr?fico para representa??o estrutural dos elementos arquiteturais, suas restri??es e intera??es. Essa tese apresenta ArchSPL-MDD, uma estrat?gia dirigida a modelos especificados e configurados usando a ADL LightPL-ACME. Tal estrat?gia est? associada a um processo gen?rico com atividades sistem?ticas que permitem a gera??o autom?tica do c?digo fonte customizados a partir do modelo do produto. A estrat?gia ArchSPL-MDD integra o desenvolvimento orientado a aspectos (DSOA), desenvolvimento dirigido a modelos (DDM), e LPS, o que permite a modelagem expl?cita e modulariza??o de variabilidades e caracter?sticas transversais. O processo ? instanciado pela ferramenta ArchSPL-MDD, que oferece suporte para a especifica??o, em LightPL-ACME dos modelos de dom?nio que s?o o foco do desenvolvimento. O ArchSPL-MDD usa como estudo de caso o middleware de TV Digital Ginga. De forma a avaliar a efici?ncia, aplicabilidade, expressividade e complexidade da estrat?gia ArchSPL-MDD, foi realizado um experimento controlado que avalia e compara a ferramenta ArchSPL-MDD, com a ferramenta GingaForAll, que instancia o processo que faz parte da estrat?gia GingaForAll, baseada em UML. Ambas as ferramentas foram usadas para configura??o do produto da LPS do do middlelare Ginga e gera??o de c?digo fonte do produto
