Research On Business Process Modeling Of Shared Hospital

Background With the continuous development and application of shared hospitals in the medical industries,the new business type of shared medical services has also received widespread concern.However,the core process of business activities in structured business process is studied and compiled by professionals,and procedural business steps can no longer able to deal with unpredictable business activities in the shared hospital operating environment.In order to meet the flexible business process requirements of shared hospitals and maintain the business collaboration among medical institutions,the improvement of modeling methods becomes more and more critical.Objective Based on the research background of shared hospital business process and the characteristics of Petri net and UML activity diagram,the business process modeling of shared hospital is studied,and then the process of algebraic theory is used to formally study the shared hospital business process model constructed by UML activity diagram.The structural conflict theory is applied to the simulation research of the shared hospital business process model to achieve flexible changes or adjustments to the shared hospital business process to ensure the correctness and rationality of the business process.Methods Firstly,the business process of shared hospital is analyzed,and the business "transaction" is taken as the basic activity unit.The business process model of shared hospital is constructed by combining DEMO transaction concept and the petri net graphic symbol.Secondly,a business process modeling method driven by use case 2.0 technology is proposed.The use case 2.0 replaces the requirements of unstructured business processes and is applied to the shared hospital business process modeling.Thirdly,according to the process algebratheory,a set of UML is introduced.The mapping rule from activity diagram to CSP adopts a method of transforming the UML activity diagram model by using CSP to formally describe and verify the high-level constructor of the activity diagram.Finally,based on the theory of structural conflict,the Enterprise Architect tool is used to simulate the shared hospital business process model.Results Research on the business process modeling,formalization and simulation of shared hospitals.Firstly,based on DEMO method,a shared hospital business process model with high abstraction level is constructed,which not only helps to understand the current situation of shared hospitals,but also builds a view of the hospital's future.Secondly,use case2.0 and UML activity diagrams to model shared hospital business processes based on structured business processes,and use case 2.0 to flexibly change or adjust business processes in structured business processes to meet the needs of flexible business processes in shared hospitals,while avoiding the complexity caused by introducing unstructured requirements into structured business processes;and through UML activity diagrams to co-operate.The core segment,internal collaboration segment,external agent and commission segment of the business process of the hospital are analyzed and modeled concretely.Thirdly,the UML activity meta model capture the main concepts and attributes of the activity diagram language.The abstract syntax of the modeling language is formalized according to the class diagram of the meta Model,and a formal representation mechanism centered on "activity" is given.To achieve formal verification of the activity diagram advanced constructor;the results show that the CSP algebra theory can not only represent the activity diagram,but also can carry out multi-level analysis of the shared hospital business process.Finally,based on the structural conflict theory and Enterprise Architect tool to simulate the shared hospital business process model,the verification results show that the shared hospital business process model constructed by UML activity diagram has structural conflicts such as livelock and deadlock,indicating that the simulation technology can achieve good simulation results.
