摘　　要：从三支决策发展历史和已有研究出发,在总结和分析三支决策近年来理论、方法、算法及应用的基础上,基于时间和空间两个维度,分别提出了时间三支决策模型和空间三支决策模型。时间三支决策注重在动态决策环境下对序贯决策进行诠释;空间三支决策主要基于"多层次"和"多视角"的粒计算思想对最优粒层和粒度进行选择。此外,对三支决策的时空性作了深入探讨和分析,厘清了三支决策发展过程和研究脉络。最后,对三支决策的研究现状进行总结,并给出未来发展方向。In this paper,the development history and recent researches of three-way decisions(3WDs) are discussed,and two models,each of temporal 3WDs and spatial 3WDs,are proposed based on the summary and analysis of theories,methods,algorithms,and applications of 3WD.The temporal 3WDs focus on the sequential decisions under dynamic decision environment,and the spatial 3WDs emphasize the optimal granular selection with "multi-level" and "multiview" strategies.In addition,the temporality and spatiality of 3WDs are investigated and analyzed in depth,clarifying the development process and research context of 3WDs.Finally,this paper presents the research status and future research directions of 3WD.
