Abstract: | To implement efficient production control, this paper provides a timed colored Petri net (timed CPN) approach to performance modeling, real-timed dispatching and simulation of Panel hull block assembly system (PHBAS). The definition of Petri net is extended to accord with the real-world PHBAS’s organization, and the modeling method for hull flow production is provided in order to simplify modeling program. Using modeling and analyzing method, the dynamic characteristics of the system can be emulated and quantitatively calculated and work control tactics can be optimized. For the double bottom hull block shipbuilding system in a recently built shipyard in China, the simulation model with timed CPN was described and the system parameters and optimal task sequence which has the minimum operation time were obtained for a scheduling case. |
