With abundant latent design rules not being extracted, the existing modeling methods present the disadvan- tages of low efficiency and deficient model quality. In that sense, a Frequent-Type-Tree model for mining process plant design rules is proposed. The model constructs a Frequent Type Tree by analyzing component attributes and topological correlations in plant models and provides real-time intelligent predictions by que- rying the tree for future design. Experimental results show that the proposed model can mine valuable l
