Analysing a new risk assessment method

Semi-quantitative risk assessment methods become more popular. However, to the knowledge of the author there are no standards about their construction so far. In this paper the requirements from a new German pre-standard DIN V VDV V 0831-101 [3] called "Elektrische Bahn-Signalanlagen: Semi-quantitative Verfahren zur Risikoanalyse technischer Funktionen (Semi-quantitative methods for risk analysis of technical functions in railway signalling)" are introduced. The requirements as given in the pre-standard are used to assess a new semi-quantitative approach for a risk assessment method for safety functions of vehicles as presented in [4]. The analysis focuses mainly on the requirements for the construction of the method. The major findings from this assessment will be explained and discussed relating them to the general procedure of constructing semi-quantitative risk assessment methods in Germany and other European countries.
