Research On System Of Systems Modeling And Model Simulation Technology Based On Complex Scenarios

With the development of modern system collaboration and integration,resource interaction between systems and between systems and environments is becoming more and more frequent,and systems are becoming more and more systematized and networked.The MBSE-based system design method faces challenges such as interdisciplinary and cross-domain,and it is necessary to extend the MBSE system design method to the structural design of the system to meet the architectural design requirements in complex scenarios.System modeling and simulation research in complex scenarios is of great significance to the research and design of systems in large-scale combat scenarios.This thesis takes combat scenarios as the research object to study the model construction and linkage simulation of the actual system.First of all,when constructing the conceptual model of the system in complex scenarios,the model elements are not clear,the model scalability is poor,and the subjective factors in the modeling process are greatly affected.This thesis proposes a conceptual model modeling method based on the DoDAF framework framework.Hierarchize and structure the actual system elements,take the combat scenario as the main background,divide the system model elements into three levels: mission level,scenario level and activity level,and clarify the system elements at different system levels respectively to form the structure of the actual system.Structured description.After obtaining the structural description of the system,through the panoramic viewpoint,capability viewpoint,system viewpoint and operational viewpoint in the DoDAF architecture framework,the structural elements of each layer are formally expressed in the DoDAF viewpoint model.Get a DoDAF conceptual model of the actual system.The DoDAF model construction follows to ensure consistency through metadata groups.The hierarchy of system elements also provides a system analysis method to realize the continuous refinement of the system model.It also enables model builders to collaboratively model different elements at different levels.Provide a basis for the analysis and maintenance of the actual architecture.Secondly,aiming at the consistency between the problem domain of the system and the simulation domain when the simulation model of the actual system is constructed,this thesis proposes a system simulation model modeling method based on the CIF hybrid state machine.On the basis of system activity-level elements,the system level is further expanded into three levels: event level,equipment level,and parameter level,and system elements at different levels are clarified respectively,and system activities are mapped to execution equipment through level expansion.By defining the mapping rules between CIF simulation model and equipment model,a CIF simulation model based on equipment-level elements and parameter-level elements is constructed.And develop model template tools according to the mapping rules,simplify the simulation model development process,and improve the reusability of simulation model codes.
