  Real-time and safety

Competencies
The engineers of Arion Entreprise are experts in security and have obtained the EOQA qualification delivered by the French ministery of Transportation.

Specialisation
- Guided transport systems and highway tunnels : expertise in the security of passengers and inhabitants, evaluation of the degree of confidence that can be attributed to the operation of equipment and its use in service.
- Evaluation of the operational security of industrial systems in terms of reliability, availability and maintainability.
- Evaluation of the quality and reliability of software.
- Technical evaluation and implementation expertise of bus protocols used in aeronautics, automotive and industy

  Tools and methods  
Arion entreprise has the necessary methods, techniques and IT tools to design and produce concrete solutions.

 Some examples of the methods and tools we use :

Functional analysis
Functional analysis enables us to break down a system into sub-systems, to identify the interfaces between sub-systems and outside environments, to identify the principal functions and funtcional constraints, and to define optimal operating conditions.

Preliminary risk analysis
This analysis enables us to identify potentially dangerous situations and to evaluate the severity of the consequences.

Operational security allowances
Allowances for operational security are used to set the quantitive objectives relative to different safety engineering parameters.

FMEA
(Failure Mode and Effects Analysis)

A systematic study of the causes and effects of failures that can affect systems components. When completed by a criticality analysis it becomes FMECA : Failure Mode, Effects and Criticality Analysis (Severity x Probability).

Reliability forecast
Input data from statistical sources is used to produce calculations that enable us to specify the hardware architectures that are the most reliable.

Mastery of regulatory and standards contingencies
ARION Entreprise has perfect knowledge of applicable standards in its field :

  • Railway Industry  : EN 50126, EN 50128, EN 50129
  • Industrial applications : EN61508
  • Aeronautics : DO 160, DO 178B, DO 254
  • Networks : EN 50159-1 and EN 50159-2

  Some examples of our approach

           For existing installations

    • Inventory of the equipment involved in operational security, operational analysis, and analysis of experience.
    • Statistical study of the reliability and availabilty of the equipment.

              In every case

    • Projections on the global security of the systems based on functional analyses
    • Risk analysis using an inductive analytical approach(FMECA)
    • Search for the causes of critical failures using a deductive approach
    • Listing of dangerous situations
    • Analysis of the operator's emergency security plan
    • Illustration of the most significant cases through different security risk scenarios
