Process Model Change Propagation Analysis Based On Abstract Technology

Information Systems(IS)is being used more and more in enterprises and is aligned with the process-oriented approach.This new generation of information systems is often referred to as Process Aware Information Systems(PAIS).In PAIS,the Business Process Model(BPM)plays an important role in helping businesses realize their business.BPM is a way of graphically displaying the organization's business processes and has become an important and relevant area of conceptual modeling.It is considered as a key tool for process-aware information systems analysis and design,organization of documents and redesign,and design of service-oriented architectures.To this end,business process models typically graphically describe at least the activities,events,states,and control flow logic that make up a business process.In addition,these models may include information on the data,organizational and IT resources involved and potential other artifacts such as external stakeholders,objectives,risk and performance indicators,and more.Although the business process modeling technology based on computer information systems is becoming increasingly sophisticated,as business systems continue to grow in size,the business processes management has become more and more important,and the requirements for business processes have become higher and higher.On the one hand,the continuous expansion of the scale of enterprises and the increase of their business capabilities will directly lead to the increasing size and complexity of the scale of business process modeling,resulting in a quick understanding of the model by the service model service providers At the same time,they bring varying degrees of difficulty and challenge to model engineers' modeling and routine maintenance.On the other hand,an enterprise's business process model involves multiple stakeholders,such as product managers,different departments,modeling engineers,model service objects,and more.Over time,different stakeholders of the process model have the potential to make partial changes to the process model.In order for a stakeholder change operation to be communicated to the remaining stakeholders in a timely manner,a sound process change communication technology is needed to achieve a common process evolution.The increasing need for process change support has given us and IS engineers new challenges and the need to use change-enabling technologies.Many vendors apply flexible software solutions to enable adaptive PAIS but often fail to address the fundamental issues associated with process changes such as correctness and robustness.The change framework provided by existing process support technologies has not been systematically compared.This,in turn,makes it hard for PAIS engineers to assess the maturity and resilience of these technologies.Therefore,this often leads to wrong decisions and wrong investments.The existing methodological research shows that it is very effective to co-evolve the process model by using the related theories of Petri nets and behavior profiles.To solve this problem,this paper analyzes and studies the process model mainly from the aspects of behavior and structure,and abstract the process model based on the behavioral profile to simplify the understanding of the large complex process model.Then use the abstract view of the process model to analyze the problem of change propagation.The main contributions of this paper are:(1)Abstraction of the process model process.First,the business process model is transformed into a workflow system based on Petri net,and a Search Tree-Based ion Algorithm based on prior search tree is proposed.Furthermore,the depth-first search strategy is used to calculate the relationship between the model's behavior and the boundary database.Thirdly,according to the node traversal order generated by the depth-first search strategy,the corresponding relevancy search tree of the model is constructed.Finally,Model to be abstract area,to complete the model of Jane.(2)Analyze the change of process model.Aiming at the relationship between the original model and the process view unique to different stakeholders,a method based on abstract technology is proposed to analyze the variation of process model.First,give a good reference flow model(that is,safe,no missing data).Second,generate different abstract views based on the abstract conditions,and make a change to the process view,given a change of process view.Finally,we analyze the change of operations in different process views,and the spread of conflict resolution.
