The Research And Application On Dynamic Business Process Management Model For Construction Project

With The rapid development of China's economy,the construction of national infrastructure and the process of urban construction has overall developed.The efficient and information-based management method can make the construction management more standardized,and at the same time,it has realized the overall and optimized process.Although researchers have achieved many results in the application of workflow at home and abroad,the traditional workflow system lacks a method for processing dynamic changes.at the same time,it can only deal with previously created process templates.Therefore,it has become one of the hot topics to improve the dynamic change of workflow management system to business processes in workflow research technology.In order to deal with the changes in the business needs of the enterprise,The paper aims to make dynamic changes in real time,and explores dynamic change processing technologies that can flexibly handle business processes based on changes in business requirements.First of all,the research status of the development of workflow technology at home and abroad is expounded,which is summarized from the theoretical and technical aspects of the dynamic change of workflow according to the enterprise needs of building settlement management.Second,according to the model established by the system,a dynamic migration strategy in different application scenarios is proposed.key technologies of the dynamic workflow has done,including the following four specific tasks:(1)By researching on workflow modeling techniques,a dynamic workflow model was proposed based on Petri nets and DNG,and meanwhile,the correctness of the model structure was verified.(2)Because the traditional workflow engine lacks flexibility and can't respond to changes in the system's requirements in real time,this paper designs a workflow engine that deals with the change process and describes the capabilities of the dynamic workflow engine.(3)Through the analysis of different type and different condition,the dynamic change strategy for different scenarios are proposed.(4)Through the design of the change processing algorithm,the process change migration decision tree is established to achieve real-time migration of workflow.Finally,on the basis of the above key technology research,the dynamic change strategy of workflow is applied in the building settlement management system.
