Modeling and Optimization of Hull Building Process Based on P-TPN

Due to the low efficiency of hull building, this paper applies timed place petri net to model and optimize the process of hull construction scheduling. We adjust the orientation block, eliminate the hatch coaming section, repartition the complicated blocks and reduce the construction difficulty. Modularization building and flow line construction are realized for most blocks. The result shows the efficiency has been enhanced greatly. Finally, according to the reasonable existing time of the markings, whether a given construction state is on rational construction schemes can be judged.
