The Research And Realization Of Scenario Modeling Technologies In Computer Generated Group Forces System

The modern warfare mode evolving from single-service arms nowadays has been changing greatly, which develops to land, sea, air, space, and electronic integrated multi-dimensional multi-arms joint operations. The new warfare mode brings out new demands for the warfare simulation technology, among which the Computer Generated Group Forces is one of the most difficult problems faced with large-scale warfare simulation training. Combined with key technologies such as artificial intelligence, computer simulation, distribution and parallel computing, the Computer Generated Group Forces system generates large-scale forces and tries to meet the demands in warfare simulation training.The warfare simulation scenario generated system is a very important part of the Computer Generated Group Forces system. It could help the users to make the warfare simulation scenario in the various conditions quickly and easily, provide the normative initialization data for the large-scale warfare simulation and improve the efficiency of the generation of the warfare simulation scenario.Analyzing on the characters and problems of the warfare simulation scenario at present, this paper considers the new demands of the warfare simulation under new situations, and makes a deep research on warfare simulation scenario model. The main work of the thesis and achievements are summed up as follows:Based on the related model and theory, an Ontology-based scenario model of organized groups is proposed. This model can provide comprehensive scenario description ability, good support for the simulation mission planning and possesses features such as strong point in model building, good reusability of the generated model.Working on the new subject of the warfare simulation scenario nowadays, a complex electromagnetic environment model based on the scenario demands is put forward. Solving the problem that comes out when warfare simulation scenario is made while building the complex electromagnetic environment, this model can describe the electromagnetic features of the warfare units clearly.Based on the related task planning theory, the description method of the tasks and the rules of the atomic behavior are redefined,and a verifiable scenario task assignment model is put forward. This model can help users to plan initial scenario task expediently and verify whether the setting of initial scenario task is reasonable, and the scenario data described in and verified by the model is beneficial to the simulation.The simulation-oriented data processing technology is realized in this paper. According to simulation environments in different platforms and the DTD defined when model parameters had determined, it parses the scenario data to XML and realizes the data interface for the simulation platform.Based on the scenario models proposed above, a scenario generated system in Computer Generated Group Forces system is designed and realized, which keeps the characteristics of the existing warfare simulation scenario generated system and provides practical solution and realization about organized groups description, complex electromagnetic environment building, task initialization, scenario verification and data interface definition.
