OpenAltaRica

AltaRica is an ‘high level’ modeling language dedicated to risk analysis (safety, reliability, performance). It is into the area of MBSA (Model-Based Safety Assessment) which goal is to decrease the substantial distance between the specifications of the systems studied and the associated ‘low level’ risk analysis models (fault trees, etc.). This distance implying difficulties at any changes to these specifications: updating ‘low level’ models is generally costly in time and in risk of error.

AltaRica has since continuously evolved since its creation in the late 90s by LaBRI with a second version named AltaRica Data-Flow. It is at the heart of several modeling and risk analysis workshops (Apsys’ SIMFIA, Dassault Systèmes’ Safety Designer, Dassault Aviation’s Cecilia OCAS). Many industrial applications have been successful and AltaRica is now a mature technology.

The last version named AltaRica 3.0, is at the heart of the OpenAltaRica project. It enhances the second version AltaRica Data-Flow in its expressiveness and ease of use.

Objectives

The main objective of the OpenAltaRica project is to develop the ecosystem around the last version AltaRica 3.0 dedicated to risk analysis of complex systems. This objective is divided on two topics:

  • Build the OpenAltaRica platform based on AltaRica 3.0 and dedicated to risk analysis of complex systems;
  • Federate the community by providing the opportunity to undertake trials of risk analysis based on AltaRica 3.0; and strengthen the competitive advantage of French industry in this area of MBSA (Model-Based Safety Assessment).

 

Challenges

Provide the reference tools for risk analysis based on AltaRica 3.0

  • Production of a coherent and comprehensive set of AltaRica 3.0. model editing, animation and processing tools;

Allow the management of models coming from the different fields of engineering system

  • Integration of risk analysis activities with other disciplines of complex systems engineering;

Ensure the productivity of modeling processes

  • Integration of libraries of component models and modeling patterns;
  • Integration of advanced methodological tools and teaching materials;

Federate a community of users around AltaRica at national level, in a first step, with the objective of become the international reference.

Target markets

Provide the OpenAltaRica platform, based on AltaRica 3.0, with the following features:

  • Production of a coherent and comprehensive set of AltaRica 3.0. model editing, animation and processing tools;
  • Design the reference and the more accuracy available tools dedicated to risk analysis based on AltaRica 3.0.

Ensure the link between MBSA activities and other disciplines of complex systems engineering, more precisely form the MBSE domain (Model-Based System Engineering).

  • Make easier the integration of MBSA activities  with the MBSE activities
  • Ensure the management and consistency of models coming from different fields of system engineering;

Ensure the productivity of modeling processes

  • Integration of libraries of component models and modeling patterns;
  • Integration of advanced methodological tools and teaching materials;

Federate a community of users around AltaRica at national level, in a first step, with the objective of become the international reference.
