The project will face following crucial objectives:

Generic Bayesian-Networks will be developed. They facilitate the direct consideration of all available sites- and object specific information of the rock-fall hazard, of the characteristics of the traffic and the characteristics of the protection gallery.

To ensure the applicability of the risk analysis tool the Bayesian-Networks are implemented into a Microsoft-Excel© environment. The user therefore needs no specific knowledge of probabilistic modeling and the risk analysis can be efficiently performed.

The development of a generic Excel©-based tool for the risk analysis of rock-fall protection includes the following five sub-ordinate targets:

1. Preliminary study and classification of all available information of the study „Simplon road A9 – Assessment of the rock-fall hazard of galleries, general inspection„ [3] (in German). 
2. Determination of an appropriate level of detail for the risk analysis subject to the problem settings.
3. Identification of all relevant parameters which should be considered in the risk analysis.
4. Development of generic Bayesian-Networks for the risk assessment under consideration of all available information.
5. User-oriented implementation of the methodology in Microsoft-Excel©.
