Abstract: In the information-based war era, OODA command and control loop is widely used in military simulation. The flexibility and efficient parallelism of distributed simulation promote the development of combat simulation. According to the requirement of combat simulation, this paper studies the core technology of distributed simulation system, which is time management algorithm. Based on the characteristics of OODA command and control loop, this paper proposes an adaptive moving time window algorithm. The algorithm adaptively adjusts the size of time window according to the model, which can avoid frequent synchronization and clear the memory accurately. In order to further optimize the time management algorithm, the author also proposes an improved global virtual time algorithm to improve the blocking process in global virtual time synchronization calculation. Through detailed analysis of the steps and principles of the algorithm, and verification by an example, the results show that the algorithm can effectively guarantee the running of distributed simulation, and the running speed is better than other traditional time management algorithms.

    OODA環(huán)理論是由BOYD J提出的軍事作戰(zhàn)中的戰(zhàn)略決策理論[1],成為對(duì)作戰(zhàn)中出現(xiàn)的沖突問(wèn)題進(jìn)行描述的一種科學(xué)方法,。該理論一經(jīng)提出,,便立即被整個(gè)西方世界的軍事界所認(rèn)可,至今仍被廣泛應(yīng)用于軍事作戰(zhàn)仿真問(wèn)題的研究[2],。眾多學(xué)者對(duì)其進(jìn)行研究并提出模塊化OODA環(huán),、智能OODA環(huán)及認(rèn)知OODA環(huán)等衍生理論[3-5]。在信息化戰(zhàn)爭(zhēng)時(shí)代,,對(duì)多國(guó)聯(lián)合軍事演習(xí),、協(xié)同軍事打擊以及與其他軍兵種部隊(duì)的共同作戰(zhàn)需求的增加,使得普通仿真難以應(yīng)對(duì)[6-7],。分布式仿真因其更高的性能及靈活性越來(lái)越多地被軍事作戰(zhàn)仿真所采用,。分布式仿真的技術(shù)難點(diǎn)是如何確保系統(tǒng)的因果邏輯關(guān)系,正確及可重復(fù)地在并行系統(tǒng)上高效合理地處理事件并推進(jìn)仿真時(shí)間,。時(shí)間管理技術(shù)是分布式仿真的一項(xiàng)重點(diǎn)技術(shù),,用于解決分布式仿真的時(shí)間推進(jìn)問(wèn)題,,它決定了分布式仿真系統(tǒng)的整體性能,被該領(lǐng)域的研究者廣泛關(guān)注[8-9],。
