文摘Logistics can be considered as the major drive of the economy.Logistics centres play a significant role in the entire logistics networks from the point of materials sourcing to the point of last mile delivery.The efficiency of a logistics network depends on the existence of logistics centres to connect and integrate entire logistics system.This article discusses the importance of selection of the logistics centre location and recommends the procedure to specify the appropriate logistics centre location as a case of Vietnam-based logistics sector.
文摘In this correspondence,we establish mean convergence theorems for the maximum of normed double sums of Banach space valued random elements.Most of the results pertain to random elements which are M-dependent.We expand and improve a number of particular cases in the literature on mean convergence of random elements in Banach spaces.One of the main contributions of the paper is to simplify and improve a recent result of Li,Presnell,and Rosalsky[Journal of Mathematical Inequalities,16,117–126(2022)].A new maximal inequality for double sums of M-dependent random elements is proved which may be of independent interest.The sharpness of the results is illustrated by four examples.
