Container transportation is an important mode of international trade logistics in the world today, and its changes will seriously affect development market. For example, COVID-19 pandemic has added a huge drag to global container logistics. Therefore, accurate forecasting throughput can make significant contribution stakeholders who want develop more operational strategies reduce costs. However, current research on port mainly focuses proposing innovative methods single time series, but lacks comparison performance different basic models same series series. This study uses nine forecast historical world’s top 20 ports compares results within between methods. The main findings this are as follows.

Maritime transport is the backbone of international trade and global economy. Resilience essential for business continuity handling unforeseen disruptions such as COVID-19 pandemic. Studies on resilience in maritime (i.e. study) have become popular due to disruptive events. To date, no research has exclusively reviewed transport. This study conducts a systematic review based 110 papers Scopus database Google Scholar from 2010 July 2022. The analysis covers various topics, including most published authors, cited articles, co-word analysis, techniques, etc. primary significance this assess state existing knowledge unearth future directions, which might help academics practitioners decide what studies pursue. our knowledge, first marine resilience.

This paper evaluates the impact of 2021–22 surge in rates for containerized and bulk shipping costs. Employing a detailed transport database applying set shocks by transportation mode, regions commodities multi-region general equilibrium model, analyses sectorial (agri-food sectors, manufacturing) macroeconomic (trade, wide-economic indicators) impacts recent Maritime costs are sensitive to imbalances between global demand supply, which rose further after Covid-19 pandemic. In globalised world, an increase can have widespread repercussions on international trade, creating risks economic activity. The results allow analysis how affect prices trade explain short- medium-term economy. main finding is that rising maritime tend reverse trend towards globalisation favour localization.

Purpose Severe disruptions to maritime supply chains, including port closures, congestion and shortages in shipping capacity, have occurred during the COVID-19 pandemic. This paper’s purpose is explore flexibility-based countermeasures that enable actors chains mitigate effects of with different characteristics. Design/methodology/approach Semi-structured interviews were conducted lines, shippers, forwarders ports. Data on pandemic's collected compared data regarding 2016–2017 Gothenburg conflict. Findings Spatial, service temporal flexibility emerged as primary countermeasures, whilst important characteristics geographical spread, duration, uncertainty, criticality, element surprise intensity. Spatial was exercised both by switching alternative During pandemic, ensuring capacity included first removing then adding vessels. Shipping lines exercising prioritised certain cargo, which made spot market uncertain reduced for forwarders, importers exporters changed carriers or traffic modes. Experience meant less better preparation spatial flexibility. Practical implications Understanding how exercise amid can support preparedness coming disruptions. Originality/value Comparing measures a pandemic versus conflict provides insights into relevance mitigation strategies.

We study a typical daily drayage problem concerning the last-mile logistics at seaports for inland container supply chains. A set of trucks available an terminal must fulfil shippers' requests transporting containers within time windows and, to do so, can perform multiple trips. request may entail picking up or delivering either premises, seaport. Demand empty be satisfied by using limited stock terminal, street-turning or, ultimately, retrieving them local depot empties resulting in extra mileage. Hence, minimization routing costs also entails synchronizing trucks' trips that retrieve and add avoid unnecessary visits depot. After modelling mathematically, we develop exact column-and-row generation approach embedded branch-and-price framework. To accelerate solving process pricing problem, propose effective strategies combining tailored algorithms. These well on adapted Solomon's instances 100 nodes against standard branch-and-cut solver. Finally, experiments real-world instances, inspired case Port Rotterdam region, provide insights into current planning practices.
