【摘要】：决策演化集是处理决策规则在时间序列上演化问题的理论,它将着眼点从静态决策信息系统转移到动态时间序列上,研究决策信息系统随时间变化的演化规律,是一种新的决策规则研究方法。目前,在决策演化集的标准结构下,其定义的演化轨迹是一个很难描绘的n维空间图形,所以本文提出了膜结构重新描述决策演化集,在膜结构下,被约简掉的属性同样会获得重视。在当时间从ti-1进入ti时,属性根据自身对决策的影响而进入不同的膜,同时所产生的数据流动也被标记出来,从而解决了决策信息系统演化轨迹具象化的问题,并通过实例演示了决策信息系统的演化过程和轨迹。
[Abstract]:Decision evolution set is a theory that deals with the evolution of decision rules in time series. It shifts the focus from static decision information system to dynamic time series, and studies the evolution law of decision information system with time. It is a new research method of decision rules. At present, under the standard structure of the decision evolution set, the evolution trajectory of its definition is an n-dimensional spatial graph which is difficult to depict, so this paper proposes a new description of the decision evolution set under the membrane structure. Reduced attributes are also valued. When time moves from ti-1 to ti, attributes enter into different membranes according to their own influence on decision making, and the resulting data flow is also marked out, thus solving the problem of the evolution path of decision information system An example is given to demonstrate the evolution process and trajectory of the decision information system.
