Design And Implementation Of Medicalbpm Workflow Engine Supporting Dynamic Processes

With the rapid development of workflow technology,the use of workflow technology for enterprise management has become a trend,not only improves the efficiency of business management,but also can make full use of enterprise resources.In the management of medical supplies field,its complex and frequently changing process makes application development difficult.However,the existing workflow engine of foreign countries do not provide the native support to the special workflow modes such as task rollback and jumping in management of medical supplies.Thus,the existing workflow engines which lack of flexibility and adaptability can not meet the needs of the application development in the medical industry.Based on the deep understanding of the existing workflow engine,this paper designs and implements a medical workflow-oriented engine,MedicalBPM,which can support the dynamic change process.Its main work includes:1)Proposed the overall architecture design of the dynamic workflow engine based on the open source Activiti5 workflow engine.The overall solution for deployment management,process management,task management,and user role acquisition based on the Activiti5 service interface is given.2)Using the extended Activiti5 service interface method to achieve a rollback,jump and other processes to solve the dynamic solution.The expansion of these core functions enables the engine to support any flow of processes,providing an effective support to complex processes in the medical field.3)The decoupling of business rules and applications is realized through the integration rule engine.The query matching efficiency is improved by reordering the order of rule files and the validity of the scheme is verified.4)On the basis of the above-mentioned key technologies,a practical dynamic workflow engine MedicalBPM is realized.With the intelligent consumable management system as the application background,the development and test of the intelligent consumable management system based on MedicalBPM validates the effectiveness of the solution.
