| Abstract: | The multilevel extension assessment method is applied to the shortest paths query system in the moving object databases. First, the extension method and the multilevel extension assessment method are introduced. Then, the evaluation factors system of the shortest paths query system based on the network is established, and the analytic and calculative method of each factor and sub-factor is proposed. At last, an example is studied to show the analytic process and that the method is effective. |
