The resilience of transportation systems has been extensively studied in the past decade. This paper aims to provide a synthesis up-to-date literature on resilient transportation, focusing concepts and methodologies. A systematic search method integrating database search, related journal citation supplement is proposed select all appropriate articles. Based selected core papers, definition examined, some are compared. main body devoted review metrics mathematical models used measure...

The congestion and disruption of information infrastructures frequently happen during disasters, which would hinder the understanding disaster scenarios, thus impede rapid response activities. With advantages high flexibility efficiency, this paper proposes to use UAVs as temporary mobile relays for data collection. However, different from many existing collection scenarios in industrial sectors, value varies with UAV arrival time service terms their importance response, makes scheduling...

Robustness measures a system's ability of being insensitive to disturbances. Previous studies assessed the robustness transportation networks single disturbance without considering simultaneously happening multiple events. The purpose this article is address problem and propose new framework assess an urban network. consists two layers. upper layer define index based on impact evaluation in different scenarios obtained from lower layer, whereas evaluate performance each hypothetical...

A fundamental and important step for safety analysis an urban transportation system is to find its critical links. However, most approaches in the current literature focused on highway or intercity systems. The key characteristics of systems were not considered concept criticality links was mixed up with vulnerability. This paper defines from two perspectives, i.e., vulnerability potential, based which a novel methodology identifying network proposed. includes ranking method mesoscopic model...

The COVID-19 pandemic has brought a brand-new challenge to the design and management of air transportation network (ATN). Many countries have partially or entirely shut down their international flights during this period contain spread COVID-19. However, changes in connectivity different varied greatly, as ATNs structures. Accordingly, paper studies impact topology on robustness country's ATN pandemic-induced disruptions. Therein, Weighted International Efficiency metric is proposed evaluate...

Abstract Global pandemics restrict long‐haul mobility and international trade. To restore air traffic, a policy named “travel bubble” was implemented during the recent COVID‐19 pandemic, which seeks to re‐establish connections among specific countries by permitting unrestricted passenger travel without mandatory quarantine upon arrival. However, bubbles are prone bursting for safety reasons, how develop an effective restoration plan through is under‐explored. Thus, it vital learn from formal...

Recently, an increasing number of companies have encountered random production disruptions due to the COVID-19 pandemic. In this study, we investigate a two-stage supply chain in which retailer can order products from low-price ("cheap") unreliable supplier (who may be subject uncertain disruption and partially deliver order) "expensive" reliable at Stage 1 more backup 2. If happens, only that were produced before time obtained supplier. It is found case with imperfect demand information...
