Hospital Workflow Modeling Based On Polychromatic Set Theory

With the development of medicine and the advancement of technology,the departments of hospitals have been divided more detailed,which contribute to the procedures in hospital more complicated.Patients spend mainly time on processes,such as waiting in the quene and various inspections.Therefore,the hospital's various inspection processes have a critical impact on the overall process,and the issues related to the hospital workflow are the urgent problems to be solved in the hospital's information system integration.Recently,many an experts and scholars research issues of workflow.However,most of them are related to the manufacturing industry and less research on hospital workflow.This article adopts related thories to model hospital workflows in order to further promote the integration of hospital information systems,and make the hospital's workflow more clear.Since the systems used by different hospitals are different and the hospital's procedures are different,how to use a uniform mathematical model to describe the hospital's workflow process model is a key issue in this study.In addition,for a hospital process,it also requires certain resources to be able to complete the corresponding activities,and the interaction between the activities of the system also need to consider security issues.Therefore,how to achieve dynamic configuration of active resources and access control between activities is also a core issue.The main work and innovations of this article include the following aspects:Firstly,this paper adopts Polychromatic Set Theory and its extension to model the workflow process of the hospital.The two-group Polychromatic Sets,K-tuple corridor matrixes,and related operations are mainly proposed,For example: extract multiplication operation,transpose extraction multiplication operation.The calculation of a corridor matrix to obtain a hospital workflow process model based on Polychromatic Graph,and the Warshall algorithm is used to verify the reachability of the polychromatic graph model of workflow process in a single system.Second,we use the corridor matrix in the polychromatic sets to model the hospital's resource management and access control,and combine resource configuration with a certain activity of the radiology framework's scheduled workflow in the IHE.Knowledge construction Role-Task Access Control Model Based on Polychromatic Set Theory.Third,integrate the hospital workflow process model with the hospital resource management model to obtain a hospital workflow model based on Polychromatic Graph.And dynamic resource allocation to an activity in the hospital process.Through the research on hospital workflows based on relevant theories and tools,a uniform hospital workflow model based on Polychromatic Graph is derived,and the Polychromatic Graph model is simplified by using simplified rules so that the starting node and the termination node pass through one.The connection of virtual nodes shows that the model has process rationality.
