ESA UNCLASSIFIED - For Official Use ESA | 01/01/2016 | Slide 2

Objectives of MB(A)SE Activities

• Support the shift from a document-centric towards a model-centric approach.

• Achieve continuity of models throughout the lifecycle:

• Automation

• Consistency

• Inter-discipline communication

• Encourage model and product reuse.

• Support the development of product lines.


Context

The SAVOIR technical note on Model-Based Avionics is available (TN-003).

It contains:

- User Needs, high level requirements, functional architecture, and tool landscape

- Mapping to SAVOIR scope and definitions

- Mapping of MBA Activities from the avionics harmonisation roadmap

- Moving the focus from a monolithic factory to a distributed one (data hub)

Also:

- Tool prototypes in development

Summary

• The technical note on Model-Based Avionics is available as SAVOIR-TN-003

• We have investigated the technologies and effort to develop model exchange tooling by building a prototype (OCDT – Capella – OSRA)

• The prototype tools will be available for evaluation as an update site, installable in Capella 1.2.x and 1.3.x

• Demo available for discussion at the exposition area


Further Work

• Tool evaluation on representative case studies, sketch model-based process

• Further development of tool bridges

• FDIR – COMPASS

• On-board Network Configuration / Analysis

• Investigate technologies for the implementation of the data hub

• Requires uniform access to data

• Requires suitable exchange formats

• Possible candidates:

• OSLC (Open Services for Lifecycle Collaboration)

• RDF / OWL (Resource Description Format / Web Ontology Language)

• ORM (Object-Role Modelling)
