Design Of Decision-making Visualization Platform Based On Smart City And Multilayer Heterogeneous Complex Networks

With the increase in the amount of data,in the construction of smart city,how to display the information about decision to decision-makers is worth studying.Multilayer heterogeneous complex networks proposed by laboratory can describe and summarize the data in the city.In the above context,the following work is done in this paper.Firstly,the decision-making visualization model for smart city is proposed.Combined with smart city and multilayer heterogeneous complex networks,this paper describes the decision-making visualization model.Taking eABC as the upper ontology,this paper establishes the ontology model in the field of smart city.This paper describes the classification system of operator in decision-making visualization model.Secondly,in this model,the ontology mapping method and the visualization configuration method are designed.This paper designs the ontology mapping method which maps dataset and ontology mode,and establishes the relationship in datasets and the relationship in data items.This paper designs the visualization configuration method which generates interface by means of configuration,and presents interface to decisionmakers.Finally,the decision-making visualization platform is designed and realized.This paper describes the framework with system architecture and data flow diagram.This paper designs the platform details from the perspective of use-case model,user interface,WebService interface and database.Based on the platform design,this paper realizes and displays the system,realizes the process of transforming data into visualization interface by means of configuration.The core of this paper is the design of the decision-making visualization platform,and the decision-making visualization model is the foundation of the platform design.This platform applies the concept of ontology and visualization technology,provides the information related to decision-making for decision-makers.The decision-making visualization system has been put into use.
