Abstract：MBD product information lightweight requires to meet the premise of preserving product semantic information to achieve geometric information lightweight.The traditional product information lightweight method can not reserve the non-geometric semantic information,so it is difficult to meet the requirement of lightweight product information of MBD.In this paper,a lightweight method for MBD product information based on improved fireworks algorithm is put forward.At first the unified product semantic model is constructed and realizes the simplification and distribution of the key feature semantics.Then,the explosion radius in the fireworks algorithm is improved,and the evolutionary dimension of the dynamically updated population is increased.Finally,the experiments shows the effectiveness and feasibility.
