Research on the Interoperability of Systems Based on the Polychromatic Sets Theory

Abstract

In view of the complexity of information system interoperability, a new method based on polychromatic sets theory is proposed, and the research steps are given. Firstly, got a polychromatic graph model for system’s interoperability relationship by analyzing the relations among the subsystems and regard it as the edges, the model’s nodes is subsystems. Secondly, the resources of each interoperability subsystem are analyzed, and the color of the nodes and edges in the polychromatic graph model are determined according to the results of the analysis. Thirdly, the actions of the interoperability subsystems are analyzed. Since the action is a movement of the state, the initial state matrix and the final state matrix of the action based on the theory of polychromatic sets are given to describe the action of the interoperability subsystem. Finally, a formal description method of interoperability system based on the theory of polychromatic sets is presented. On the end, the interoperability of hospital information system as an example to verify the effectiveness of this formal method.
