This thesis proposes a method called PM-MDA for the development of Platform Models in the context of Model Driven Architecture (MDA). The PM-MDA method focuses on the development of embedded software projects based on Real-Time Operating Systems (RTOS). Additionally, this study defines a UML 2.0 Profile for Modeling Application and Platform of Embedded Software (PROAPES), which is used in the PM-MDA method. Such profile defines a set of stereotypes to generically describe Platform Models (PMs) and Platform Independent Models (PIMs). Further, extensions are defined in this profile, e.g. the PROAPESX profile, allowing the modeling of PMs into versions of the X RTOS Real-Time Kernel and associated hardware. In its turn, the PROAPES profile enables the link of a PIM to a PM, allowing these models to be entered as input attributes in a Model Transformation. In the context of MDA, this profile is a platform metamodel for building PMs, i.e., a metamodel of a family of similar platforms. In this way, a PM is used as a fundamental part in the development of embedded software in the MDA approach by providing means of obtaining platform independence. In current MDA approaches, model transformations implicitly employ PMs. As the concerns regarding the platform are not separated from the concerns related to model transformations, for each required platform there must be one or more corresponding model transformations that are configured specifically for that platform. This results in model transformation processes that are expensive and difficult to be automated. In some application domains such as embedded systems, the use of MDA is more motivating because of the heterogeneity of platforms and the complexity of these systems. The PM-MDA method, which makes use of the PROAPES profile, aims to systematize the process of creating and providing platform models separated from the model transformation process, enabling the generation of efficient and adaptable model transformations.
