摘要: 决策演化集的纵向演化是在决策演化集的基础上处理决策规则在不同粒度空间上演化问题的理论.决策演化集的纵向演化并不拘泥于静态的决策规则,而是把着眼点放在决策规则的在不同粒度空间的动态变化上.在决策演化集的纵向演化中提出了隐藏属性、丢失属性、纵向演化矩阵、演化偏移角和纵向演化轨迹等概念,但在目前的决策演化集的纵向演化的理论体系中很难将决策信息系统的纵向演化轨迹以及其他的演化特性具象化出来.提出使用膜结构来重新描述决策演化集的纵向演化,建立了决策演化集的垂直膜结构理论框架,从而解决了决策信息系统的纵向演化轨迹、隐藏属性、丢失属性、演化偏移角等的具象化问题,将之前不能画出的演化轨迹及演化偏移角、隐藏属性、丢失属性等演化特性展示出来,使得对决策规则的纵向演化的研究更为直观,并通过实例演示了决策信息系统的纵向演化过程和轨迹.
