报告摘要:

“3”是一个奇妙的数字,它既表示了“多”,也描述了“开始、中间和结束”三个阶段、三个部分或三个单元。不难发现,基于三个单元的思维方式在我们日常生活中常常用到。三支决策(three-way decisions)给出了一个基于“三”的复杂问题求解新理论,可以理解为基于三个粒的粒计算。我们将一个整体分为三个部分或三个粒,对不同的部分采取不同的处理策略。“分”是实现“治”的一种方法,而“治”是“分”的目的。“三分而治”的三支决策模型以“分”开始,以“治”结束,从而有效地简化了复杂问题的求解过程。围绕“三分而治”,讨论三支决策的基本思想及三元思维的方式、方法。在认知时代(cognitive era),三支决策研究将逐渐兴起,并产生深远的意义。
