Business Process Model Configuration Optimization Method Based On Petri Net

Business process management has many advantages,such as improving enterprise operational efficiency,shortening the running time as soon as possible,the flexible use of business process management to solve all kinds of change problems.The same process may correspond to different models,but some do not meet the requirements,it will produce changed model.At the same time,the quality of the business process depends on the pros and cons of the model.And with the rapid development of the Internet era,business process mining has been a new application field of management,the analysis of business process correspond to the event log,mining hidden changes or blocking changes to obtain a more complete process model,and improving the work efficiency.Currently,enterprise management has focused on combining with the configurable change to optimize model.Now,for a given target model,the analysis of the changes range mainly through the active node,the calculation is complicated;mining hidden changes of business process model mainly based on sequence analysis,but rarely considering the inter relationship between sequences,so it has a certain impact on the mining business process hidden change;for given the log,but no target model,often through static positioning change region,and then optimizing and analyzing the business process model,improving the existing model.In this paper,combining with the behavior profile and the Petri net,mining hidden changes of business process model through the process tree cut and considering the given target model or no target model,optimizing and analyzing domain changes from different angles.The main contributions are as follows:For a given target model,to search domain change problem of model,optimizing boundary transitions and inter-boundary transition based on behavioral profiles interactive behavior to determine uncertain range.And combining with support and compliance to find target model change region,not only simplifying the calculation,but also reducing the difficulty of analyze change range.According to mining and optimizing hidden changes of business process model,the method to find hide transitions of business process is proposed based on the process tree cut.Firstly,the source model is obtained according to the higher frequency of occurrence log sequence.Then preprocessing log by the process tree cut,comparing the log relationship with the relationship of the initial model,and finding changes region,mining the possible hide transitions.Determining the optimal model with hide transitions through the evaluation criteria.This method which analyzes business process model not only from the business process sequence,but also consider the inter relationship between sequences and from multiple perspectives,to overcome the limitations of existing methods.The intelligent optimization of business process model,combining the method of the Petri net and behavior profile.Firstly,from the log behavior angle to dynamic analysis change parts of the business process,matching with the relation between log and model,and dynamic localization,determining the change region of model,then considering the interface part,finally using the fitness and behavioral appropriateness,optimizing model with the configuration change and it is the best model,to overcome the limitation of static search change range.
