反坦克直升机任务效率评估

军用直升机在初步设计时就需用运筹学（Ｏｐｅｒａｔｉｏｎｓ Ｒｅｓｅａｒｃｈ）方法评估其战斗有效性。直升机与坦克一对一战斗结果，胜负过程符合马尔柯夫随机过程（Ｍａｒｋｏｗｖ Ｐｒｏｃｅｓｓｅｓ）。直升机战斗有效性判据是作战兑换比，即损失一架直升机可击毁敌坦克数。本文分析这个过程，列出随机微分方程组，推导出作战兑换比公式，从百找出提高战斗有效性途径，使战斗有效性评估有数量概念。

THE EVALUATION OF MISSION EFFECTIVENESS OF THE ANTI - TANK HELICOPTER

It is necessary to evaluate the combat effectiveness of military helicopter in primary design. The combat result of helicopter vs lank one by one corresponds with Markov random process.The criterion of combat effectiveness is loss ratio, i. c. if one helicopter be lost, how many enemy tanks be destroyed. This paper analyses this process with random differential equation derived the equation of loss ratio,thus, the methods of improving mission effectiveness are obtained.
