Formalization of Hospital Workflow Process Based on Polychromatic Sets Theory

Abstract

In order to establish the workflow model, formalized expression of workflow process was studied. The basic conception of polychromatic set is given, to describe the relationship between activities and activities, this paper extends the Boolean matrices in polychromatic sets, on the basis of 0,1 to increase the -1 to identify the relationship between the follow-up relationship, with "+" that the relationship between the activities of the precursor. In addition, in order to construct a complete workflow process, the polychromatic graph is extended. In this paper, the classification of nodes in polychromatic graphs and the addition, deletion and modification of polychromatic graphs are proposed, add a pair of to the edge of the polychromatic graph to indicate the time and resources required to complete the activity. Finally, using the theory presented in this paper to describe the workflow process of hospital radiology.
