Performing multi-viewpoint analysis : Thales case-study

A domain where MDE is widely used is System Engineering. In this domain, Thales has acquired a strong experience with the Arcadia approach.

Arcadia is a model-based architecture engineering approach which has been tooled up in Eclipse with Melody Advance, a generic workbench developped  by Thales Engineering & Process Management with the assistance of Obeo.

Based on EMF and GMF, Melody Advance allows other Thales entities to create their own modeling tools. These modeling tools are declared with a dedicated DSL which is interpreted to dynamically provide the corresponding GMF modeling editors coming with ergonomic facilities and supporting large models.

This approach has several objectives:

• To perform early validation of key architectural aspects to decrease the rework in design and production
• To improve the quality of architecture by taking better descisions regarding complex but necessary architectural trade-off
• To capitalize on both product definition and know-how by supporting negotiation and compromise between stakeholders
