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.)

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.
