摘要
信息更新问题是控制决策系统中普遍存在而又极为重要的研究课题.二阶概率技术在这些问题的研究中有着广泛的应用前景.文中结合一个目标识别问题中的应用实例,系统介绍了二阶概率技术的应用过程以及建立在二阶概率技术上的一种概率更新方法,并利用该方法解决了一个目标识别问题中的信息更新问题.
Updating of information when new evidence or knowledge becomes available is both common and important procedure in decision-making. The second order probability technique is quite useful to carry out this procedure. The purpose of this paper is to introduce this technique and a probability updating method under this technique. Using this method, a problem of updating information in target identification is solved.
