The AltaRica Association provides the systems engineering and reliability engineering communities with two types of products:

• Software tools that are distributed free of charge, including for commercial purposes.
• Courses and trainings that are given in both academic and industrial contexts.

Tools

The AltaRica Association hosts the intellectual property of a number of software tools. Some of these tools are publicly available, some others are used only for teaching or research purposes.

AltaRica Wizard

AltaRica Wizard is an integrated modeling environment for the high level modeling language AltaRica 3.0.

AltaRica Wizard provides most of expected functionalities of a code editor: syntax highlighting, management of copy and paste, line numbering and so on. AltaRica Wizard manages AltaRica 3.0 models into projects. Projects gather the different AltaRica source files of a model, as well as some files generated by assessment tools.

In addition to model authoring functionalities, AltaRica Wizard embeds three tool chains to assess AltaRica 3.0 models:

• A stepwise simulator (also called stepper);
• A compiler into fault trees;
• A stochastic simulator.

These assessment tools are developed independently of AltaRica Wizard. Some of them have been developed in the in the framework of the Open-AltaRica project hosted by IRT SystemX.

Since 2021, AltaRica Wizard and the associated assessment tools are distributed directly by the AltaRica Association. AltaRica Wizard can be downloaded from the AltaRica Wizard web page.

XFTA

Simply put, XFTA is a powerful and efficient calculation engine for fault trees and related models. XFTA is however much more than that:

• XFTA has a high expressive power, as it provides a full-fledged object-oriented language to design models: S2ML+SBE.
• XFTA implements state-of-the-art assessment algorithms and a wide range of calculations of risk indicators, which cover most, if not all of, the needs of probabilistic safety analyses.
• XFTA is fully documented as it comes with the XFTA Book, which provides an in-depth presentation of mathematical and algorithmic frameworks of probabilistic safety analyses, a complete description of XFTA commands and numerous application examples.
if not all of, the needs of probabilistic safety analyses.
• XFTA is free of use, including for commercial purposes.

Courses and Trainings

The AltaRica association proposes courses and trainings that can be given in academic and industrial contexts. This includes:

• Basic courses on reliability engineering and system safety.
• Courses on the model-based approach in safety assessment.
• Courses on the AltaRica 3.0 modeling language and the AltaRica Wizard modeling environment.
• Courses on the XFTA calculation engine and its use to perform probabilistic safety assessment.

Courses and trainings can be delivered on-line or on-site, according to the needs of the hosting structure.
