摘要

新冠肺炎疫情在全球范围内产生了巨大的负面影响,所有运输方式以及航空货运都受到了负面影响。本研究的目的是利用时间序列对所选变量进行预测。在提供COVID-19的一般信息后,将预测结果应用于时间序列建模,寻找恢复周期的返回时间。它分析了2016年1月至2021年5月期间的可用吨公里、收入吨公里、载客率、国内生产总值、国内和国际货运。研究结果表明,货运因子长期受国内运输影响,短期受国际运输影响。因此,航空货运由于其全球地位,首先受到国际运输的影响。预测结果显示,从2021年2月开始的恢复期,由于航空公司对货运的关注发生了变化,2021年7月将继续保持强劲的增长趋势。疫苗接种完成后,主要涉及客运,随着飞机配置的变化,航空货运也受益于这一增长趋势。本文的贡献表明,从GDP的角度来看,使用客机进行货运以增加恢复期的速度,以尽量减少经济损失的必要性。©2022,德国联邦物流公司(BVL)。版权所有。

Forecasting Recovery Period of the Airfreight Transportation from Covid-19 Pandemic by using Time Series Modelling
COVID-19 has a dramatically negative effect globally, so all transportation modes also airfreight have been affected negatively. This study aims to forecast the airfreight load factor by applying time series to the selected variables. After providing general information about COVID-19, the forecasting results apply to the time series modeling finding the getting back time into the recovery period. It analyzes between January 2016-May 2021 with available tonne-kilometer, revenue tonne-kilometer, load factor, gross domestic product, domestic and international freight. The findings show that the cargo load factor is affected by domestic transportation in the long-term and international transport in the short-term periods. So, airfreight is firstly affected by international transport due to its global position. The forecast results show that the recovery period started in February 2021 and will continue with a robust growth trend in July 2021 due to the changing airlines’ focus on freight transportation. After the completion of vaccination, primarily related to passenger transportation, airfreight transportation also benefits from this growth trend with the configuration change of aircraft’. This paper’s contribution shows the necessity to minimize the economic damage by using passenger aircraft for freight transport to increase the speed of the recovery period in terms of GDP. © 2022, Bundesvereinigung Logistik (BVL).

期刊介绍: Submissions that are most appropriate for NRL are papers addressing modeling and analysis of problems motivated by real-world applications; major methodological advances in operations research and applied statistics; and expository or survey pieces of lasting value. Areas represented include (but are not limited to) probability, statistics, simulation, optimization, game theory, quality, scheduling, reliability, maintenance, supply chain, decision analysis, and combat models. Special issues devoted to a single topic are published occasionally, and proposals for special issues are welcomed by the Editorial Board.
