In the design of process plants safety has assumed an increasingly high profile. One of the
techniques used in hazard identification is the fault tree, which involves first the synthesis of
the tree and then its analysis. The construction of a fault tree, however, requires special
skills and can be a time-consuming process. It is therefore attractive to develop computer
aids for the synthesis stage to match those which already exist for the analysis of the tree.
A computer based system for fault tree synthesis has been developed at Loughborough
University. This thesis is part of a continuing programme of work associated with this facility. [Continues.]
