The complexity of e-commerce logistics is mainly reflected by its diversity and multi-objectives of different domains which the logistics involved in. In this paper, we give a special object-oriented Petri net's definition composed by Unique Set, Service Net and Data Set, then use it to model a typical e-commerce logistics. Firstly, we analyze the process' requirements in order to abstract four objects which are Customer, EC Center, Warehouse Center and Transport Center. Secondly, correspond with these objects, we build four sub-processes which are order sub-process, operation sub-process, warehouse sub-process and transport sub-process. After those we analyze the model's aspects of encapsulation feature, inheritance feature and polymorphism feature, and provide a flow robustness analysis of the typical e-commerce logistics based on hierarchical thought.
