Analysis of Data Export Business Processes Based on Petri Nets

In the context of globalization and rapid development of information technology, cross-border flow of data has become an important part of international trade. This paper firstly analyzes the necessity and risk of data cross-border and discusses the relevant legal framework in China. Secondly, this paper, for the first time, uses Petri nets to model the business process of cross-border data flow, effectively and comprehensively describing the steps and interrelationships in the three phases of data transmission: before transmission, during transmission, and overseas maintenance. Finally, the proposed model is simulated and experimented by PIPE software, which verifies the boundedness, security and deadlock-free characteristics of the model, and proves the feasibility and necessity of Petri nets in the application of cross-border business processes of data.
