摘要 本文研究了两组异质组合的线性积聚量的序列特性.在增凸序或者增凹序意义上,提供了充要条件以得到线性积聚量的比较结果.此处获得的部分结果加强并推广了一些已知的结果.一个数值例子验证了理论的结果. This paper studies the ordering properties of the linear aggregation arising from two sets of heterogeneous portfolios.The sufficient conditions are provided in the sense of the increasing convex[concave]order to compare the linear aggregation amounts.The results obtained here strengthen and generalize some known results.A numerical example is given to verify the theoretical results.
