Background

YAP is a research tool

  • for risk modelling—particularly, to explore and investigate abstract state spaces for situational risk analysis—and
  • for controller synthesis—particularly, the synthesis of controllers for run-time handling of hazardous events occurring during the operation of autonomous systems.

I am developing YAP as an aid to my research on the design of verified controllers for risk-aware autonomous systems. YAP can be interesting for engineering practitioners involved in the modelling, verification, development, or certification of safety-critical embedded systems in this application domain.

The research in the context of YAP has been supported by the Assuring Autonomy International Programme, the University of York, the German Research Foundation, the Technical University of Munich, and the German automotive industry.

Accidental Similarity of Names

By coincidence, there is a Prolog interpreter called YAP (Yet Another Prolog). YAP Against Perils is not related to, building on, or using Prolog software. If you like Prolog as much as I do, please, have a look at YAP. YAP Against Perils is also not related to the speech recognition software, the DVI/PostScript previewer, or the island or state in Micronesia.
