CREATION OF OPTIMAL MOVEMENT STRATEGY OF PLURAL MOVING OB-JECTS BY GA

The topographic information of a closed world is expressed as a graph. The plural mov- ingobjects which go and back in it according to a single moving strategy are supposed.The moving strategy is expressed by numerical values as a decision table. Coding is performed with this table as chromosomes, and this is optimized by using genetic algorithm. These environments were realized on a computer, and the simulation was carried out. As the result, the learning of the method to act so that moving objects do not obstruct mutually was recognized, and it was confirmed that these methods are effective for optimizing moving strategy.

基于改进径向基神经网络的船舶设备故障诊断方法

针对目前船舶设备故障诊断方法存在适用性不广、准确度不高等问题,引入径向基神经网络船舶设备故障诊断方法。提出一种基于反向学习和自适应搜索策略结合的改进人工蜂群算法,通过反向学习策略进行蜜源初始化,提高初始解的质量,并在迭代过程中自适应调整搜索步长,提升原算法的收敛性能和局部寻优能力。将该算法与径向基神经网络的参数寻优相结合,构造性能良好的故障诊断分类器。实验结果表明,该方法有效提高了故障诊断的准确性和适用性,满足船舶设备故障诊断的实时性能要求。
