The concept and role of strategic airlift were introduced, which showed its domestic and international developments and gaps in the field of modeling and simulation. To solve this problem, the deployment flow algorithm building strategic airlift model was used. It involved strategic airlift entities present, computing methods of air path planning algorithm, air time planning method and air loading capacity planning method. The process of the algorithm was improved by the three coordinate conversion calculation process air path to improve the computational efficiency. By the experimental verification scenario, the experimental process and experimental results, it verified the validity and applicability of the algorithm framework. Also it provided a reference method for strategic airlift modeling method in warfare simulation. Source

The limitation of the traditional communication model modeling methods was analyzed. On the basis of detailed analysis the requirements of communication modeling and simulation, the method of communication model modeling method was designed based on the communication effects. It shows how to represent communication asset and combines the input and output of the model with the simulation verification scenario to illustrate the validity and applicability of the communication model. This method can effectively solve the impact analysis of communication problem for operational effectiveness, saves development costs and supplies the reference method of C4ISR model in warfare modeling and simulation. © 2015, The Editorial Board of Journal of System Simulation.

The development history of multi-resolution modeling technological in the world was described, which illustrated the technology is the key of warfare modeling and simulation. Combined with the technology application in each combat zone, the deficiencies in the C4ISR application were pointed out. Based on the analysis modeling requirements, combined with sensor asset representation in the warfare simulation system, the low, medium, high resolution of sensor model from two aspects were built, including the sensor performance and report attributes. By the verified scenario, the consistency of the multi-resolution model was described. This method can better solve the problem of large-scale warfare simulation system and resource consumption, the complexity and the efficiency of model. Source

Although it leads to system complexity, emergence also provides the opportunity to make the system have the ability of adaptive evolution. Introducing the concept of emergence into the system design process, a new approach was proposed to combine the top-down design method of classic engineering and the emergence-based bottom-up design method, which could satisfy the requirements of orderliness and emergence simultaneously. The organization of military command and control required a structure of tiers, at the same time, the phenomenon of emergence often disordered this structure. Accordingly, the networked combat model as a nested hierarchy of OODA (Observe-Orient-Decide-Act) loop was created, which has mechanism to hierarchically tune the emergence for optical self-organization.
