The underlying philosophy of three-way decision is thinking in threes, namely, understanding and processing a whole through three distinct and related parts. One can formulate many concrete models of three-way decision to account for different interpretations of the three parts. By interpreting the three parts as three levels, this paper investigates tri-level thinking to build concrete models of three-way decision. We examine some fundamental issues and basic ingredients of tri-level thinking. In accordance with the data–information–knowledge–wisdom (DIKW) hierarchy, we present a perception–cognition–action (PCA) tri-level conceptual model that is applicable to studying intelligent data analytics, intelligent systems, and human understanding.

三级思维：三路决策模型

三路决策的基本哲学是三分思维，即通过三个不同且相关的部分来理解和处理一个整体。一个人可以制定许多三路决策的具体模型，以解释这三个部分的不同解释。通过将这三个部分解释为三个层次，本文研究了三个层次的思想，以建立三方决策的具体模型。我们研究了三级思考的一些基本问题和基本要素。根据数据-信息-知识-智慧（DIKW）层次结构，我们提出了一种感知-认知-行动（PCA）三级概念模型，该模型适用于研究智能数据分析，智能系统和人类理解。
