摘　　要：根据船舶吊装过程中所涉及的吊装网络约束、场地和设备约束,以及所用时间等信息,提出了一种基于共享合成时间Petri网的船台吊装过程建模方法。该方法不仅能够应用于单船吊装过程,而且可以方便地建立多船吊装过程模型。分析了该方法的可行性,给出了具体的合成算法和利用极大加法代数求解所建模型中相关时间的方法,从而提高了这类复杂过程建模的效率。最后,通过一个实例,对具体多船吊装过程建立时间Petri网模型,并给出了这类模型优化后的结果,进一步说明了该建模方法的有效性。To deal with erection constraints of block erection process in shipyard such as block erection facility, space, equipment and consumed-time, a method based on sharing synthesis of timed Petri net for modeling of block erection process in shipyard was proposed. This approach could be employed to model the erection process of single vessel or multi-vessel. Feasibility of this approach was analyzed and composite algorithm was presented. Efficiency of this complicated process modeling was improved by solving time-related factors in the model with maximum addition algebra. Finally, a case study of modeling and optimization of erection process of two 74,500 DWT bulk carriers was given, and the result showed that this modeling method was effective.
