Book Description
This book studies air cargo capacity control problems. The focus is on analyzing decision models with intuitive optimal decisions as well as on developing efficient heuristics and bounds. Three different models are studied: First, a model for steering the availability of cargo space on single legs. Second, a model that simultaneously optimizes the availability of both seats and cargo capacity. Third, a decision model that controls the availability of cargo capacity on a network of flights.

Book Description
The scope of this thesis is to propose a structured methodology for improving the airlines' and freight forwarders' actions when confronted with accepting demand and acquiring capacity respectively. We develop methods to tackle two air cargo revenue management problems: space allocation and show-up rate estimation.

Book Description
This book uses numerous examples to describe the current opportunities and risks of air freight against the backdrop of stagnating transport volumes since the financial crisis in 2008. It shows what impact these developments have had on those involved, in particular shippers, airlines, airports and freight forwarders. The application-oriented presentation also provides an insight into the design of complex supply chains and the areas of tension in which the players in air freight operate.

Book Description
Dynamic programming (DP) is one of the most powerful tools for finding the optimal booking policy for capacity control of a single leg flight. However, the extension of it to a network of flights is impractical due to the exponential growth of the size of the model with number of legs in the network. In this work we develop and use an approximate DP model to find the optimal protection levels on a single leg flight and extend it to a network of flights as well. We develop a Markov chain to calculate the expected revenue that is generated under implementation of a fixed policy at each stage of the approximate DP model and for any remaining capacity and then search for the optimal policy. We use large time chunks in the proposed DP model to decrease the computational effort and show that the resulting expected revenue converges to the expected revenue that is generated under implementation of the original DP approach. Unlike many of the existing models, in our proposed method, nesting is incorporated into the optimization procedure. Furthermore, by using the proposed Markov chain model, the expected generated revenue can be calculated directly and without using simulation.

Book Description
This is the Proceedings of the Eighth International Conference on Management Science and Engineering Management (ICMSEM) held from July 25 to 27, 2014 at Universidade Nova de Lisboa, Lisbon, Portugal and organized by International Society of Management Science and Engineering Management (ISMSEM), Sichuan University (Chengdu, China) and Universidade Nova de Lisboa (Lisbon, Portugal). The goals of the conference are to foster international research collaborations in Management Science and Engineering Management as well as to provide a forum to present current findings. A total number of 138 papers from 14 countries are selected for the proceedings by the conference scientific committee through rigorous referee review. The selected papers in the first volume are focused on Intelligent System and Management Science covering areas of Intelligent Systems, Decision Support Systems, Manufacturing and Supply Chain Management.

Book Description
This book proposes capacity options as a flexible alternative air cargo contract type, and illustrates how capacity can be priced through option contracts. The analysis is accomplished by means of an analytical multivariate optimization model under price and demand uncertainty. A case study using data from a leading German carrier illustrates the financial potential. Finally, the author shows how capacity-option contracts integrate into the context of air cargo revenue management.

Book Description
Dynamic capacity management is the reassignment of aircraft to a flight schedule in response to the realisation of demand. Through better matching of the supply and demand for seats, airlines are able to carry more passengers, and the revenue management policy should be adjusted accordingly. This paper proposes a derivative (EMSRd) of the widely used EMSRb booking limit calculation method, which takes into account the effect of possible future capacity changes. The EMSRd approach only depends on the fleet assignment problem through the probability distribution of the aircraft type that operates each flight, and can be solved efficiently once these have been estimated. Numerical experiments show potential revenue improvements of over 1 per cent.
