Analysis of the effect of extreme weather on the US domestic air network. A delay and cancellation propagation network approach

Flight delays are one of the most discussed, yet not fully understood, topics in the aviation industry. In this paper, we shed more light into propagation of flight delays by providing a spatio-temporal analysis of flight departure delays of the US domestic air network for the year 2017. The analysis focuses on four US air carriers (full-service...

The ground handler dock capacitated pickup and delivery problem with time windows: A collaborative framework for air cargo operations

We study a typical problem within the air cargo supply chain, concerning the transportation of standard Unit Load Devices (ULDs) from freight forwarders’ to ground handlers’ warehouses. First, ULDs are picked up by a set of available trucks at the freight forwarders’ premises within a time window. Next, they are delivered to the ground handlers,...

A combined forecasting and packing model for air cargo loading: A risk-averse framework

In this paper, we present a combined forecasting and optimization decision-support tool to assist air cargo revenue management departments in the acceptance/rejection process of incoming cargo bookings. We consider the case of a combination airline and focus on the passenger aircraft belly capacity. The process is dynamic (bookings are received...

Auction-based coopetition in the landside air cargo supply chain

Increased competitiveness with other transport systems and declining operation margins have motivated freight forwarders in the air cargo transport industry to look into horizontal collaboration. This paper focuses on developing a fully integrated five-phase auction-based coopetition model, a form of horizontal collaboration where competition is...

Integrators' global networks: A topology analysis with insights into the effect of the COVID-19 pandemic

In this paper we propose, to the best of our knowledge, the first analysis of the global networks of integrators FedEx, UPS, and DHL using network science. While noticing that all three networks rely on a “hub-and-spoke” structure, the network configuration of DHL leans towards a multi-“hub-and-spoke” structure that reflects the different...

Analysis of the air cargo transport network using a complex network theory perspective

In this paper, we present a complex network analysis of the air transport network using the air cargo, instead of the passenger, perspective. To the best of our knowledge, this is the first work where a global cargo network comprising passenger airlines, full-cargo airlines, and integrators’ capacity was studied. We used estimated yearly cargo...
