信息扩散模型的窗宽优化与鱼雷战术效能实验评估

Assessment Experiment on Torpedo Campaign Efficiency Based on Information Diffusion With Window Width Optimization

针对海洋环境对鱼雷等武器装备战术效能影响的试验数据和案例样本匮乏等普遍性问题,引入信息扩散和模糊映射思想,并基于遗传算法改进和发展了最优窗宽扩散模型。该方法可从有限的试验样本中客观拟合出数据结构信息,进而实现有限数据样本信息的合理扩散。利用该方法进行了基于小样本案例的潜射鱼雷战术效能的海洋环境影响评估的信息扩散建模和仿真实验及对比分析。结果表明,窗宽优化的信息扩散模型可有效改进常规信息扩散模型的评估效果,对武器装备环境影响评估中普遍存在的小样本或信息不完备困难有一定参考价值。

Aiming at the universal shortage of essential experimental data for evaluating the efficiency of oceanic environment influencing weapons such as submarine torpedo,etc,the optimal window width information diffusion theory improved by genetic algorithm and fuzzy mapping were both introduced to solve the problem of little-data samples.From the limited data samples,their structure information can be objectively fitted out,which makes it possible for the rational diffusion.By making an emulational test and comparative analysis,it is validated that the research idea and technique may improve the assessment result of the normal information diffusion model and suggest for such evaluation problems as in imperfect information condition.
