Language-Oriented Programming (LOP) advocates designing eXecutable Domain-Specific Modeling Languages (xDSMLs) to facilitate the design, development, verification and validation of modern softwareintensive and highly-concurrent systems. These systems place their needs of rich concurrency constructs at the heart of modern software engineering processes. To ease theirdevelopment, theoretical computer science has studied the use of dedicated paradigms for the specification of concurrent systems, called Models of Concurrency (MoCs). They enable the use of concurrencyaware analyses such as detecting deadlocks or starvation situations, but are complex to understand and master. In this thesis, we develop and extend an approach that aims at reconciling LOP and MoCs by designing so-called Concurrencyaware xDSMLs. In these languages, the systematic use of a MoC is specified at the language level, removing from the end-user the burden of understanding or using MoCs. It also allows the refinement of the language for specific execution platforms, and enables the use of concurrency-aware analyses on the systems
