SYNCHRONIZED SIMULATIONS IN PLANNING SYSTEMS

摘要: The U.S. Military is embracing technologies that provide enhanced situational awareness and enable rapid decision-making. idea to gain option dominance over an adversary through superior collection, integration, presentation of information more decisionmaking. Considerable effo rt being expended meet the current challenge developing systems analyze, filter, integrate relevant into a common operational picture. Once commanders have this improved ability observe understand battlefield environment, next will be determine best ways make use knowledge. Meeting with appropriate planning decision support should not wait until informationproviding are operational. One way develop in parallel information-providing produce as if already existed. technique for exercising these run simultaneous simulations – one provides 'real world' state stimulates system, or system uses track progress plan new branches based on actual state. For work, must re main synchronized operation progresses. This paper explains motivation such simulation systems, determines associated requirements, describes two evaluate methodologies. BACKGROUND There many wealth about enemy friendly activities, weather, terrain, etc. under development. Now all sensor data reports integration area very active research, it reasonable expect high-fidelity, high-value near future. remaining question how provided by future systems. approach answering replicate existed, start building Planning maintain representation attributes activities entities therein. A merged execution monitoring compare (and perhaps projected states) against determination whether re-planning necessary. (maybe several instances) multiple remain continues. If states various “close” real operation, any conclusions recommendations made would suspect. purposes paper, synchronization defined process keeping (including clock) within some small amount variance external another simulation, real-world command control does mean running time. difference between which (or at least constrained tolerance).
