Abstract

Usually, risk assessments are done qualitatively or quantitatively. Neither of these two approaches is satisfactory. In the future, risk assessment methods combining the advantages of both approaches are recommendable. Based on the life cycle process as described in DIN EN 50126, the paper discusses guidelines for the construction of semi-quantitative risk assessment methods and presents a newly developed semi-quantitative risk graph for the application to the railway sector.
