Intelligent System Engineering Platform


Intelligent System Engineering Platform

Workflow Engine for Analysis, Certification & Test

What is it?

Intelligent System Engineering Platform consists of the WEFACT framework which provides a flexible infrastructure for defining and executing V&V processes. External resources – external processes, tools and standards – are integrated into the WEFACT framework by well-defined interfaces. The safety case of security case respectively is the central output of WEFACT. It summarises the information of the V&V process and provides a basis for the certification of the artefact under test (AUT.)

What it Does

  1. Guides users through the V&V (verification and validation) and certification process
  • Follows functional safety and security standards
  • Provides a workflow starting from definition of requirements to generation of modular and incremental safety and security cases.

2. Helps in identifying and carrying out V&V activities

  • Organises V&V activities in C-plans (validation plans) for controlling the V&V process, supporting traceability and tracking the status.
  • Supports automatic and manual processing of V&V activities using customised integration of V&V methods and V&V tools.

3. Collects documented evidence in repositories

  • Provides an interface for external data and document repositories.
  • Provides templates for reports, e.g. V&V activity reports, validation reports and safety and security case reports.

Also Supporting You With

Test Plan Reviews

  • Gain confidence in your test plan following the appropriate norms

Identifying & Closing Gaps in Testing with State of the Art

  • Following norms might not be enough – know the size of your blind spot
  • Obtain updated test plan/tests closing gaps to the state of the art

Safety Audit Rehearsals

  • AIT’s senior experts help in preparation for an upcoming safety audit

Review of Security Concept and/or Internal Development Workflows

  • Identify potential weaknesses and necessary improvements
  • Based on applicable standards, AIT will review development workflow and suggest improvements

Study and Technology Evaluation & Workshops

  • See how you can profit from new technologies (e.g. virtual testing, automated code analyses)

Reducing the Carbon Toll of Railway

Digital Rail are working on a project that seeks to use advanced Natural Language Processing (NLP) to identify non-compliance against railway standards during the development of railway system. Non-compliance will cause a lack of resilience which will be linked to likely train service delays and the associated carbon toll. The toll is caused by having to lay on additional  rail services, buses, maintenance, and so on. The carbon toll of a system will therefore be known during the design phase which will be  major step forward in understanding how clean our railways are likely to be.

It has been shown that modern electric railway transportation is environmentally friendly when compared to normal occupancy car transportation and carbon usage in the railway is mainly in operations. For a given concept of operation, the environmental impact of the system and the resilience are ”baked-in” in the downward part of the V lifecycle as shown in the Figure 1 below.

NLP is a technique that is not widely used in the rail industry and there is an opportunity to apply it to the critical systems engineering areas such as requirements, hazard log development and management. NLP is being applied more widely in other domains such as social media and advertising.

The environmental impact that is caused by lack of resilience includes: laying on additional train services, bussing, maintenance etc. This does not included the wider consequence to the public of lost working hours. Environmental  Life Cycle Analysis (ELCA) during other phases is not in our scope.
