决策演化集的垂直膜结构

Vertical membrane structure of decision evolution sets

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.

Vertical evolution of decision evolution sets is a theory to deal with evolution problem of decision rules in difference granular spaces based on decision evolution sets. Vertical evolution of decision evolution sets does not research static decision rules. It focuses the dynamic process of evolution of decision in different granular spaces. Vertical evolution of decision evolution sets presents the concepts of hidden attributes, lost attributes, vertical evolution matrix, angle of evolution deviation and vertical evolution trajectory. But, at present, the original theoretical system of vertical evolution of decision evolution sets is hard to draw the trace of vertical evolution of decision information system and others properties of evolution. This paper uses membrane structure to re-description the vertical evolution of decision evolution set, and build the theoretical framework of vertical membrane structure of decision evolution sets to work out the problem of the decision information system. It＇s difficult to show evolutionary trajectory, hidden attributes,lost attributes, and angle of evolution deviation. In this paper, evolutionary trajectory, hidden attributes, lost attributes and angle of evolution deviation, which cannot be drawn in original theoretical system of decision evolution sets will be shown. Vertical membrane structure makes the research of vertical evolution of decision more visually. This paper uses an example to show the process and trace of vertical evolution of decision information system.
