OVERVIEW OF THE RAIL DOMAIN

Main goals

The main goals for Rail Domain are to innovate processes and products based on complex and hybrid railway systems, exploiting the methodologies and the tools for the design and for the V&V activities improved in CRYSTAL. In particular:
  • To mature innovative techniques, methods and tools developed in other research projects in order to bring them to a level of maturity which is compatible with a pre-deployment in European railway industry. The Technology Maturity Level (TRL) targeted is at least TRL5 at the end of the project, so that an industrial deployment on operational environment can be envisaged in the three years after the end of CRYSTAL.
  • To create within within the railway supply chain a common railway vocabulary based on ontology technology for improving data exchange and increasing competitiveness reducing rework and misunderstanding between railway actors.
  • To implement the interoperability concept based on the interoperability standard initiated in the frame of CESAR and enhanced in the current project.
  • To set up To set up customized industrial framework relying on the CRTP and the platform builder capabilities.

Goals and Innovations by Ansaldo STS

 Goals:
  • Decrease V&V effort, reducing time to modify test cases after changes in requirements and to maintain the entire test suite
  • Decrease certification effort, simplifying the analysis of the test results and improving the traceability
  • Taking on the challenge of the setup of an interoperable multi-company testing environment (interoperability tests to be executed in laboratory and not on the field) compliant to the standards under definition by Unisig
Innovations:
  • Semi-automatic generation of test cases from system model
  • Automatization of information traceability (from system requirements to system model to generated tests to test reports)
  • Generation of the main artifacts (test scripts, logs, etc.) in company-specific and/or in European Railway standard language (IOP language)

Goals and Innovations by Thales Austria

Goals:
  • Accelerate overall development process, improve time-to-market
  • Increase efficiency of safety engineering, overcoming the shortcoming of manual inspection of the fulfilment of safety requirements
  • Improve SW and documentation quality
  • Improve design for maintainability, enhance the maintainability of the system
Innovations:
  • Automatic generation of system/component test cases based on test model or specification model
  • Establishment of traceability from the requirements to the test result

Goals and Innovations by Alstom

Goals:
  • Structure and strengthen the development platform and framework of the train Information systems
  • Perform the safety Analysis related to the Alstom Transport use case and automatically generate the Safety Engineering artefacts
  • Improve the integration between the requirements management Tool, the Design Tool and the Safety Analysis Tool
Innovations:
  • Propose a Safety Management Platform that supports the Safety Analysis Techniques and automatically generates the Safety Requirements
  • Improve interoperability and bridge the gap between the MBSE and the MBSA

Main results

The first period M1 - M12 of the project has been use to create a strong basis to fulfill the overall goals listed above. In particular, the main results achieved for the period are the following:
  • Definition/description of the company-specific use cases which can provide the basis for the validation of the CRYSTAL results and the TRL assessment.
  • Investigation of existing standards and ontology catalogues in order to create a solid basis for a widely accepted vocaulary.
  • Presentation of first demonstrator.
