中文摘要：

为了降低建模的难度,更加容易、直观地描述系统的动态过程以及其中的逻辑关系,将逻辑Petri网的建模技术应用于物流配送系统中,对其进行了建模与分析。基于对物流配送系统一般工作流程的分析,比较准确明了地描述了配送系统的动态运作过程,建立了系统的逻辑Petri网模型,并研究了系统的某些重要性质。

英文摘要：

In order to reduce the difficulty of modeling, to describe the dynamic process of the system as well as logical relations more easily and intuitively, the basic theories of logical Petri net technology are applied in the logistics purchasing system which carried on the modeling to it and analyzed in this paper. The system＇s general work processes are analyzed. The dynamic operation process of the logistics purchasing system was described well and truely, and its logical Petri net model was established. And moreover, some important characters of this system are analyzed bdsed on the model.
