“…However, the ULD dispatch problem, which is different from the above [1][2][3][4][5][6][7][8][9][10][11][12], has rarely been studied in the past. Lu and Chen [13] focused on the problem of weekly airline ULD dispatch planning. ey developed a network model with a min-max objective for a planning stage problem.…”

This study is devoted to a new research topic in real-time airline operations, the redispatching of unit load devices (ULDs) under demand variations. We develop a new hybrid framework to solve the problem of ULD redispatch following the time-sequence decision-making required by airlines. The hybrid framework is developed by integrating techniques including the probability distribution technique to simulate different types of operational demand, the adjustable number of stages which is needed to meet the requirements of a decision-making process following a time sequence and the time pressure characteristic of real operations, and the scenario tree and probability rule approaches which are aimed and representing all possible demand scenarios for a stage, while the network flow technique is applied to represent the movement and location of ULDs at each airport over time and is used for the development of the associated mathematical model and the simulation. We performed a simulation of 2,000 cases based on different operational days and types of operational demand. The results show that this hybrid framework is able to achieve stability and also a small variability of both ULD operating costs and solution times, which could allow the airline to save on ULD operating costs, under demand variations in real-time operations.

“…ULDs inventory control concerned about equipment provision for loading operations [5]. The assemblies of ULDs in a load plan affect not only available capacities of loaded freights which performance reflects on the load factor of every flight but ULDs repositioning also [6]. Special contours of containers and flexible stacks of pallets affect the sufficient uses of equipment capacity.…”

Loading efficiency of freighters plays an indispensable role for the service performance of international air express companies. This study examined the priorities of factors to affect freighter loading efficiency at Taoyuan International airport (TPE) with an analytic hierarchy process (AHP). Unit load device (ULD) inventory control, load factor and load plan were ranked top 3 from 15 factors by practical experts. This study used the technique for order preference by similarity to ideal solution (TOPSIS) to evaluate 26 flights of MD11 freighters operated by an international air express company at TPE. The results revealed that the performance ranges between the best and worst flights were obvious.

“…In the global air transport industry an important area of technological advancement in recent times has been in aircraft unit load devices (ULDs). Unit load devices, or ULDs, are pallets and containers which are used to load passengers' baggage, air cargo and mail onto a wide-body aircraft (Lu and Chen, 2011;Baxter, Kourousis and Wild, 2014). The International Air Transport Association (IATA) estimates that there is currently around 700,000 ULDs in use by the world's airlines, with an estimated replacement value of close to approximately $USD1 billion (International Air Transport Association, 2013a).…”

Unit load devices (ULDs) are pallets and containers which are used to carry air cargo, mail and passengers baggage on wide-body aircraft. Using an in-depth case study, an empirical investigation was undertaken to examine the recent technological developments and innovations in the temperature-controlled containers that are used extensively in the growing and highly important air cargo cool chains. The results demonstrated that advances in refrigeration systems and the use of composite materials used in the construction of these containers have enhanced the ability of key stakeholders to provide unbroken cool-chains. The study further demonstrated that the services and expertise of Envirotainer, the case company, as well as its strategic partnerships with key stakeholders, underpin its ability to deliver and capture value from its participation in the industry.
