To verify the performance of MCBA, we study two cases. The first case is a G/G/1 queuing problem with the optimal parameter setting difficult to determine. The second case has an additional binary decision variable representing two different dispatching rules. Compared with the results of Optimal Computing Budget Allocation, the proposed approach is observed to achieve higher probability of correct selection under the same simulation cost.

为了验证我们方法，我们用了两个例子，第一个例子是在G/G/1系统搜寻一组难以找到最佳参数的例子，第二个例子则是延续第一个例子，额外加进了另一个二元因子，代表不同的派工法则，跟另一个方法OCBA比较后，可以发现我们的方法能够获得较高的正确选择机率，在相同的模拟资源下。

According to the characteristics presented by armed helicopters during cruising or searching for ground targets, this paper has established the mean-square deviation stationary random model of helicopter tracks. It is an important method to decorrelate the measure noise by estimating the parameters of the color noise online. Kalman filtering and forecasting have been made with helicopter tracks. The simulated study has been carried out on helicopter tracks under the condition of color noise. It is very difficult to get an accurate and reliable prediction when the data is very limited. The paper make use of the theory of grey system to resolve the problem of prediction of helicopter tracks, establishing the GM model of grey systems and the cumulative residual error model of n degree, then correcting the GM forecast model. In the period of sampling, GM model and residual error model have been established on line to improve prediction precision.

结合武装直升机在巡航或搜索地面目标的特点，给出直升机航迹模型为协方差平稳随机模型，在线估计有色噪声参数，对测量噪声去相关，对直升机航迹进行卡尔曼滤波与预估，最后对有色噪声条件下的航迹进行了仿真研究；在数据非常有限的情况下，准确地预测又很困难，本文提出了用灰色系统理论解决直升机航迹预测问题，建立了灰色系统GM预测模型和n次累加残差模型并对GM预测模型进行修正，在每个采样期间内，实时在线建立GM预测模型和残差模型以提高预测精度。
