Research On Key Technologies Of Simulation Model Reusability And Composability

Along with the modeling and simulation technology in military field problem research and engineering practice of the application of expansion and thorough, the field of accumulation of the simulation model reuse problems gradually be taken seriously. Researchers and engineers common hope can through the flexible assembly for simulation model, fast construction to meet different application demand of the simulation system, timely response study system evolve continuously, keep the structure composition, the behavior and process of the validity of modeling and simulation.Based on the combination of simulation model reuse and combination technology as the research object, by the maritime combat capability analysis evaluation of modeling and simulation for background, in establishing support model reuse and combination of the modeling simulation based on the conceptual framework, according to simulation model reuse and field problem space relevance, simulation concept model framework of model combination process features such as guidance, using military conceptual model, simulation scenario description standard, the concept semantic matching degree calculation and extended color Petri net technology, is proposed based on the simulation model and application environment description concept matching degree model can be reuse judgment method, based on the simulation of CPN conceptual model frame combination modeling and correctness verification technology, and with the simulation model resources search frame prototype design and large tf air defense command and control process modeling simulation as an example, the key technologies used in the example. The concrete content includes:Analysis of the simulation model reusability and composability relation, put forward two kinds of simulation composability development mode; Constructs the support model reuse and combination of the modeling simulation conceptual framework, the establishment of a simulation model reuse and combination of the concept system, Gives the formalization of the simulation model can reuse decision method and model integrated modeling and verification analysis method.From the point of view of the problem space field analysis of the existing model to describe the shortage of the method, is proposed based on military conceptual model simulation model description method; In the simulation scenario description standard expression on the basis of analysis, is proposed based on the simulation scenario model application environment description method; To model the application of environmental compatibility as the core, is proposed based on model and application environment description concept matching degree model can be reuse judgment method, and give a matching degree quantification algorithm.Put forward the concept model simulation framework and internal relation model, the establishment of a simulation concept model framework SMC_ECPN combination model, and analyzes the model description ability, and gives the combined model grammar, operation control flow, data dependence and data mapping and so on four aspects of accuracy detection algorithm.Examples show that this paper puts forward that the simulation model of the reusable judgment method improves the simulation model retrieval and reusable judgment to the accuracy of the results; Put forward the concept of the simulation model frame combination modeling technology, independent of the specific simulation model to realize language, can also describe framework between model of control flow and data flow, support arrangement, graphical model combination description, can effectively detect combination model exist in the process of mistakes.
