Note:

The traditional air cargo supply chain is composed by the shippers, the freight forwarders and the airlines. The freight forwarders secure capacity with airlines in order to accommodate shippers' demand. They bid for capacity six to twelve months before the actual departure date of the aircraft, and confirm the needed capacity a few days before departure. We address the freight forwarders' problem of confirming needed capacity based on balancing the costs of ordering too much capacity versus ordering too little. We use a Markov decision process to model the problem. We show the value function is convex in the state variables for lead times of one and two periods. We present the structure of the optimal policy and show it is stationary. In addition we present solutions to the case with subcontracting options and order due dates. We also address the airlines' revenue management problem with respect to its cargo capacity available for free sale (after honoring committed capacity to freight forwarders), in particular the problems of (1) accepting/rejecting incoming bookings based on bid prices, and of (2) estimating the show-up rate (ratio of bookings handed in at departure over bookings on hand) with impact on overbooking. To address the lumpiness of demand, we split the cargo into two categories: small cargo, composed of mail and small packages, and large cargo, composed of the bulk of commercial cargo. The small cargo is approximated with the passenger arrival, and we propose a new algorithm to solve the traditional probabilistic nonlinear problem from the passenger side. The large cargo is solved using a dynamic program, which is decomposed at the leg level using a fare-prorating scheme. The solution from our new approach is shown via simulation to be superior to two approaches currently used: the first come first serve, and the deterministic linear program. The show-up rate is estimated using wavelets and we show that a discrete show-up rate is more suitable than the traditional Normal estimator used in practice. The new estimator results in considerable more potential revenue.

This thesis discusses the background, contents and airpolitical consequences of the so-called 'Horizontal Agreements ("HA"),' concluded by the European Union ("EU") with third countries to give effect to the European Court of Justice's ("Court"/"ECJ") decision of November 2002 in the 'Open Skies' cases brought by the European Commission ("EC"/"Commission") against certain EU Member States. / The Court's decision outlaws the nationality or 'ownership and control' clause in the bilateral ('Open Skies') agreements concluded with the United States by those Member States. As this clause is a standard provision in all bilateral air services agreements, the Court's decision actually obliges the Member States to amend those agreements and replace the said clauses by provisions which do not discriminate on the basis of nationality. / The Member States have in the meantime mandated the Commission to engage in such negotiations on their behalf on the basis of a jointly developed Model Horizontal Agreement ("MHA"), containing a non-discriminatory so-called Community clause and some other provisions on matters within the exclusive competence of the Community. / This research thus examines the legal and airpolitical implications of these Horizontal Agreements, which the Commission has concluded in the meantime and continues to propose to third countries. In this connection, attention is given to the scenario of the anticipated Horizontal Agreement negotiations between the EU and the Republic of Korea.

In the first study, we formulate the passenger and cargo allocation problem as a variant of the price-dependent multi-item newsvendor model with capacity constraints. The effects of baggage weight, pricing, and costing on the number of passengers and amount of cargo carried are studied. Based on the model and the existing practice of carriers, we develop several illustrative cases and fend that to maximize profit, large aircraft may need to reduce their baggage limits significantly from the current policy. / In the second study, we propose the dynamic partnership concept, which assures a feasible partnership in an online logistics community. After identifying the platform requirements, a preliminary knowledge framework which describes the collaborative knowledge and new knowledge managing approaches is suggested. / In the third study, we provide a two-phase framework for an airfreight forwarder's resource planning. In each timed phase, an optimization model first determines the aggregates and a simulation model then examines the disaggregated situations evaluating whether the aggregate estimates are viable under disaggregation and uncertainties. Here, a set of measurements are established to evaluate the performance of a resource plan. For the inadequate plans, areas of possible improvements are identified for revision. / Three studies in air cargo logistics are conducted respectively, covering the following three areas: carrier's passenger and cargo management, logistics service provider's partnership strategy, and an airfreight forwarder's resource planning. / study 1. Optimal baggage limit policy: airline passenger and cargo allocation -- study 2. Dynamic partnership in online logistics community: concepts and a knowledge framework -- study 3.
