In most cases, heightened structural safety leads to higher costs and therefore to a reduction of average disposable income. At the same time, average life expectancy rises because of the ensuing lower failure rates. From income and life expectancy, it is possible to derive socioeconomic utility functions such as the life quality index. A safety-relevant decision is deemed acceptable if the utility function value rises or remains at least equal. The thesis extends this approach in order to cover not only mortality effects, but equally effects upon morbidity. Furthermore, the effect of delays (latency) is investigated. A generalised consequence model facilitates the determination of mortality and life expectancy from failure rates and toxical emission rates. Realistic case studies illustrate the application of the proposed methods.
