A new approach for computer-aided fault tree generation

A new method for automated fault tree generation is presented in this paper. In this method, every system is modeled as a set of components and flows. Each component is described by its function tables and state transition tables. Saving the designed components in a component library keeps them available for future use in other systems. A trace-back algorithm works on system model, and generates the required fault trees. Reencountered or inconsistent events are removed from the tree. The proposed approach is capable of modeling different types of systems having various kinds of components and connections. A sample system is presented to show how this method works.
