Abstract: For granular computing lacks a unified model and method，the paper builds a tetrahedral structure model of Granular Computing disciplines based on the four basic elements of Granular Computing discipline——granular thinking，the basic theoretical framework，granular problem solving and granular information processing，and then expounds the meaning and significance of the tetrahedral structure mode.It provides integrated synergies of four basic elements，and the stable mechanism of the tetrahedral structure model through separately mutual integration of the "four vertexes" and "four faces" of the tetrahedral structure model of Granular Computing.

Key words: granular computing, unified model, basic elements, tetrahedral model, stable mechanism

摘要： 针对粒计算缺乏统一的模型和方法的现状，以粒计算学科的四个基本要素──粒化思维方式、基本理论框架、粒化问题求解和粒化信息处理为基础，构建了粒计算学科的四面体结构模型，诠释了四面体结构模型的内涵和意义，探讨了四个基本要素相互之间的立体协同作用。通过分别对粒计算四面体结构模型“四个顶点”和“四个面”的相互整合，对该四面体结构的平稳机制进行了深入研究。
