%X 摘要： 借助于n维模糊数空间上的偏序关系, 提出和定义了n维模糊映射的预不变凸性, 包括n维模糊映射的预不变凸、严格预不变凸、弱严格预不变凸、预拟不变凸、严格预拟不变凸、弱严格预拟不变凸性;进而讨论了各种预不变凸性之间的相互关系;并对其相互关系进行了举例说明。<br>Abstract: By means of the partial order relation in n-dimensional fuzzy number space, some preinvexity of n-dimensional fuzzy number-valued functions are defined, including preinvexity, weakly preinvexity, strictly preinvexity, weakly strictly preinvexity, prequasiinvexity, weakly prequasiinvexity, strictly prequasiinvexity, weakly strictly prequasiinvexity, and so on. In addition, their interrelation of the preinvexity of n-dimensional fuzzy number-valued functions are discussed, and some examples are given to illustrate the interrelation of the preinvexity
