Modeling And Analysis Of Tax Process Management System Based On Petri Net

The establishment of the tax process management is one of the representative applications of China's current advocacy of e-government.It will directly serve the national finance staff and the majority of taxpayers,and achieve modern,informationbased tax management.Because the tax process is very systematic and complex.At present,due to the systematic and complex of the taxation process,there are issues such as complex process of related processes,overlap of departmental functions,unclear responsibilities,and lack of performance assessment,which has led to the disadvantages of slow work and repeated processes,which has reduced work enthusiasm and efficiency.While the medical process has gradually matured and facilitated,people also urgently need more convenient and efficient taxation processes to make taxpayers more efficient and transparent in taxation.Therefore,the modeling of the tax system and the optimization of the process are the focus of this study.This will lay a theoretical foundation for the concrete realization of the system and the further optimization of the workflow in the future.It will be of great significance to improving the efficiency of the taxation department,tracking the responsibility of the work flow,and evaluating the performance of the personnel.This paper first introduced the development status of tax process and workflow technology at home and abroad.Then elaborated on the core concepts of tax process and management,workflow management technology and Petri nets related definitions.Then the paper puts forward the idea of using Petri net modeling tools to model and analyze the tax process,and the specific analysis methods and theoretical basis.On the premise of consulting related literature and existing technologies,a three-tiered architecture model suitable for tax process management modeling is proposed.Then analyze and design the main modules of the business.Through the summary and analysis of daily tax work flow,design the main tax process and modeling of the process by the Petri net,and establish the tax process model.Finally,Petri net analysis method are adopted.After rigorous mathematical calculations,the rationality of the process model is theoretically demonstrated.This laid a reasonable theoretical basis for the model.This paper has some theoretical,applicability and innovation based on Petri nets to modeling the business of tax process management.It will lay a solid theoretical foundation and effective decision-making support for the promotion of E-government and taxation process informationization in the future.
