一种武器系统效能评定的新方法

A New Method for the Evaluation of the Effectiveness of Weapon Systems

以灰色系统理论中的灰靶技术为基础,在对原靶心度求解公式加以改进,并建立了一种新的武器系统效能的评定方法.即:首先用灰靶理论建立评定方法的数学模型,以能反映武器系统效能的战技性能指标构造各比较方案或模式的指标序列,进而求得各指标序列的标准模式.通过求各比较模式对标准模式的靶心度,并按大小排序,最终确定各比较方案效能的优劣.在对AK 74,AK 47,M 98K三种步枪进行效能评定的实例中,本方法所得三种枪的靶心度分别为:γ(x0,x1)=0.983 7>r(x0,x2)=0.737 3>γ(x0,x3)=0.643 9;传统方法所得三种枪效能的火力突击指数为:E1=2.52>E2=2.25>E3=1.00.就效能优劣而言,本方法的结论与传统方法的结论以及三种步枪在战场上长期使用的实际情况一致.即:AK 74最好,AK 47次之,M 98K居后.本方法的计算过程为简单的代数运算,且不涉及许多传统方法中类似人工打分之类带有一定主观性因素,所以,就同时满足可操作性和客观性而言,本方法较传统方法为优.

By improving the formula for solving the approaching degree, a method for evaluating the effectiveness of weapon systems according to the grey target principle is established. The grey target theory is used to set up the model for mathematical evaluation; the tactical and technical performance indices, which reflect the effectiveness of weapon systems best, is used to form the index series of weapon systems to be evaluated（namely, the modes）, and the standard mode of these index series is derived according to the grey target theory, thereby evaluating the effectiveness of weapon systems as can be evaluated by solving the degrees of approach of each mode to the standard one. In the case in evaluating the effectiveness of rifles AK74, AK47 and M98K, the approaching degrees of AK74, AK47 and M98K are respectively 0. 983 7, 0. 737 3 and 0. 643 9. The fire assault indices of AK74, AK47, and M98K, which reflect the effectiveness of rifles, as solved by the conventional method, are respectively 2.52, 2.25 and 1.00. Regarding the effectiveness, this method gives the same conclusions as the conventional one and the actual performance of three weapons in battlefields ; AK74 is the best, AK47 the second, and M98K the third. The method is improved in meeting both objectivity and maneuverability simultaneously, for its calculating process is mostly of simple algebraic operation, and need not to deal with those subjective factors based on score-giving by experts in many of the conventional methods.
