Abstract


The scenario is the basic premise for war simulation, whether traditional military exercises or modern computer simulation of war are inseparable from the scenario. At present, the operational mode has been developed from single combat mode to the joint operational mode under the conditions of modern high-tech, combat formation, joint operations, combat missions, combat environment, combat level than in the past is much more complex, especially for large Combat Simulation System distributed and heterogeneous characteristics, to combat simulation studies and simulation scenario development raised many new issues. The existing think most of the fixed-generating system is tightly coupled with a specific platform or system, independence is not strong; system architecture and development of technically there are differences, and different given data structure and stored, the system difficult to interact; system application is limited in scope, is generally limited to the internal network, private network or local; want to set the data structure is not flexible enough, does not support the cutting and reconstruction based on the existing scenario, reusability. Therefore, this article is designed and implemented based on XML given description and heterogeneous data conversion mechanism, developed a set of Web services and BPEL technology-based distributed visualization combat scenario generation system to achieve the scenario prepared deduction. The main thesis work including the following aspects: 1) analysis of the main problems faced by the current simulation scenario generation to explore the use of Web services technology to achieve advantage To set generation system of design of Web-based services, BPEL technology system of the hierarchical system architecture . 2) XML-based simulation scenario description, to achieve a given data combined with cutting function. 3) designed to support heterogeneous data conversion method of self-defined data mapping rules are given a data mapping rule generating step, to achieve the conversion of the heterogeneous data given. 4) complete the system function module Web Services package BPEL-based portfolio of services. 5) military geographic information system graphical interface-based simulation scenarios visual editing and deduction. The main features are: 1) the use of XML, Web services and other general-purpose technologies, standards and open architecture to promote a scenario generation system scalability, interoperability and reusability, in future modeling and simulation direction of development. 2) system with specific simulation application loosely coupled, to cross the C4ISR systems, combat simulation applications, legacy think given generation system simulation resources heterogeneity of the underlying data structures, rapid reuse of heterogeneous scenario data, so that the interaction between the simulation system more flexible, to achieve the integration of heterogeneous simulation resources. 3) makes it want to given data structure has a certain degree of flexibility and scalability, and provides a guideline for our military simulation would like to set the development of standardized XML-based scenario description. 4) The system can be deployed within the scope of the WAN to support collaborative development of combat scenarios, scenario development efficiency. This design of scenario generation system achieved in the the military academies field exercise command and control simulation system, improve the production efficiency of the drill scenario, to achieve the interoperability between heterogeneous simulation exercise system, and promote the legacy simulation resources scalable and reusability.
