Research On Supply Chain Finance Based On Petri Net

Small and medium-sized enterprises(SMEs)due to poor financial situation and other reasons,in normal production activities have a shortage of funds,The shortage of funds may lead to supply chain funding break,The supply chain financing can effectively alleviate the financing problems of SMEs.At present,the supply chain finance is still in the initial stage of development,supply chain finance business process haven?t form a unify and mature process to regulate,this will become a risk to members of the supply chain and the financing institutions.Supply chain financial can solve the financing problems which faced by SMEs and alleviate the shortages of funds in SMEs,it also can achieve the benign development of the supply chain.Therefore,this paper studied the finance business process of supply chain finance,the stochastic Petri nets with the introduction of time parameters were selected to model and analyze the business process of supply chain finance.In this paper,the research background and theory of supply chain finance were expounded,and also reviewed the current research situation of supply chain finance and Petri net methods,we used Petri net Research methods to study business process of supply chain finance.Through the investigation of the enterprise,we got and analyzed the financing business process of the enterprise?s supply chain finance.The Petri net model was established,then the dependency graph was used to analyze causal relationship in business process and output the key events.Then the stochastic Petri net model of business process was established and the basic properties of the model were tested.By analysed the steady state probability and the utilization rate of the transition model,we analyzed the performance of the model.We also obtained the inefficient and time-consuming aspects of the financing business process.The study of supply chain finance was based on business process,this paper analyzed the business process of the enterprise financing from the perspective of causation and complemented the deficiencies of the existing literatures.Combining the modeling analysis of Petri net,it optimized the financing business process of the enterprise and given some suggestions for the improvement.We reconstructed the optimized Petri net model,standardized the enterprise financing business processes and improved the efficiency of the actual operation in financing process.
