Abstract

The complexity degree of modern chemical plants demands for the use of formal specification methods. A framework for hybrid systems contains specification modules and verification elements proving the plant safety. The design of a plant is reduced to the composition of framework components, the identification of possible sources of danger and the identification of suitable verification elements.

Our contribution introduces a tool supporting the selection of suitable safety properties eliminating possible sources of danger. The tool harmonic supporting this process is based on approaches of expert systems. An example examination of a plant specification clarifies the use of this program.
