Research on WAP supervision with system dynamic model

In this paper, the WAP supervision is studied with dynamics system method. Firstly, the value-added service is analyzed based on the structure of industry chain. A system dynamic simulation model of WAP industry chain is established, which describes the interaction of the elements in the WAP service. Based on the running results of this model in the VENSIN PLE software, we predict the market prospect of WAP service and give the conclusion that the government and the operators are the key factors of reducing harmful WAP information.
