The microalloying method is most widely used in the production
process of high strength steel bars. However, its cost factor has become the
main bottleneck for its difficult promotion. The incomplete structure of
analytic hierarchy model is established in this paper to identify the primary
and secondary elements affecting the performance and investigate the influence
mechanism. The dominance numbers are especially introduced to revise the final
weights. Hence under the premise of ensuring the mechanical properties of the
steel bars, the cost is controlled by increasing the input of certain elements
and reducing the use of other expensive micro-alloying elements.
