The study involves, describing the nature of the airline industry, especially in the African situation with some of its problems being high airfares and inaccessibility within the continent. In order to address these problems an analysis of the minimal operating costs and challenging factors affecting route costs needs to be carried out. The aim of the study was to develop from first principles, a cost model to calculate operating costs along any route in the African continent. The costing of an airline service is reviewed through existing literature and a compilation of the structure, components and their equations and default values was done. A model structure to calculate these operating costs on a route is set up, while data is analysed to provide inputs to the model. The model is then applied to carry out an analysis of the type of service provided in terms of costs and service quality. Africa specific data is then included in the model in terms of passenger trips and sector distances and these are embedded into the model. The main conclusion drawn from the study was that this model could be used to design optimally an airline service based on operating costs using existing passenger demand and sector distance. The model was applied to a route within Africa and results showing how smaller capacity aircraft even though limited by maximum range are the most economical to run along routes when the frequency of flights is high. / Dissertation (M Eng (Transportation Engineering))--University of Pretoria, 2006. / Civil Engineering / unrestricted

Thesis (PhD)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: For more than a decade there has been an economic need to mitigate the negative effects of the air transport industry's innate sensitivity to cyclical developments as well as the effects of its inherent lack of substantial profits. The past 20 years were additionally marked by a change in policy that prompted various countries to liberalise and privatise their civil passenger air transportation industry. At the same time, airlines' business ambitions became more global, tapping into markets beyond countries' or continents' main gateways. All three aspects started to change the pattern of airline competition and required new business models. Key features of airlines' novel business models are geographic expansion and thus market development. Global expansion strategies and market development activities in passenger air transportation are, however, not easily and fluidly executable. The airline industry is, to some extent, still nationally regulated, thus impeding passenger airlines from fully participating in the global market-scene and from freely entering promising geographies. Concomitantly, the competitive landscape in which scheduled passenger airlines operate changed drastically, with travel value chains occasionally undergoing revolutionary transformations on both the supply and the demand side. Finally, the air transport service reveals several peculiarities that impact its production, distribution and consummation. These characteristics have inspired the execution of novel forms of competitive strategies that are described and critically discussed in this dissertation. Within this context, a main root cause for passenger airline partnerships appears to be its continued regulation and the circumvention thereof through the horizontal joining of forces, thus emulating concentration tendencies that have long been a fixture in other globalising industries. Consequently, horizontal interairline partnerships were induced and identified as a key competitive device with which to weather the challenges of the new air transport rivalry structures, the increasingly deregulated environment, and the impediments of sustained market regulation. All major airlines are now involved in some type of horizontal collaboration. The spectrum of these linkages is wide and ranges from loose, unattached, operative agreements to long-term, far-reaching, strategic ones, the most salient forms and instruments of which are thoroughly scrutinised in this dissertation. This dissertation additionally presents the general core inducing economic drivers of carrier interrelationship, which are cost reduction, revenue generation and corporate power considerations. While these aspects offer a multitude of possible partnership forms and instruments, the bulk of airline linkages, however, is presently constituted of joint revenue generation and, consequently, jointly pursued marketing and market expansion goals. In view of these causes, the present dissertation engages in a profound discussion of the rationales behind interairline partnerships, their likely evolution and effects on management practice. Essentially, the key importance of airline partnerships in meeting basic economic imperatives on the one hand, while circumventing persistent regulation on the other, questions the sustainability of incumbent carriers' current business models. There are clear indications that a structured sequence of events in establishing interairline linkages is a key success factor for horizontal airline partnerships. However, the empirical examination of contemporary partnerships' governance structures and managerial practice strongly points to a lack of ample tools with which to establish airline partnerships, select the appropriate match between alliance goals and intensity, and govern alliances during their entire life-cycles. This drawback seems particularly unacceptable in view of the urgent requirement for more appropriate managerial practice in today's discontinuous air transport business environment, and speaks loudly of the need for a framework with which to enhance airline partnership output. Most ideally, a coherent, structured sequence of events should be followed in partnership formation, organisational set-up and management in order to bring an alliance to fruition. On this basis, the establishment of a collaboration governance organisation, adequately mirroring the specific partnership type and meeting the specific demands of all partners involved, is equally identified and described as a fundamental success driver in this dissertation. Further structural, organisational and functional issues thereafter need to be considered in order to transform the joint business venture of two horizontally allied carriers into a venture for mutual success. The most essential of these are introduced in this dissertation. Synergy plays a central role in this context. Synergy, as the overreaching intention and result of working together towards a common goal, must be anchored as a prime objective of all forms of partnership activities. Synergy through interfirm linkages can be derived from various collaborative areas and is greatly influenced by both internal and external factors. One gauge for synergy, in particular for the transformation of synergy potentials into synergy effects, is partnership intensity. The measurement of partnership intensity can be used to perpetually monitor the benefits of partnership activities. At the same time, inconsistent or uneven partnership intensity can indicate the existence of dissynergies or frailties in the alliance. The underlying theories of collaborative synergy generation, its main drivers and impediments, with particular reference to horizontal partnerships of scheduled passenger airlines, are explored in this dissertation. In recognition of the theoretical and practical background of airline partnerships and the acknowledged problems associated with their establishment and operation, the present dissertation proposes a novel model dynamically supporting the quest for synergy in airline interrelationships. Incorporating the goals of synergy generation and its continual measurement in interairline partnerships, the synergy audit is designed as a dynamic managerial tool. The synergy audit functions as a recurring device for unleashing all the positive partnership benefits of collaborative scope and width. It aids airline alliance management in transforming the desired benefits of partnership activities - synergy potentials - into real, tangible synergy effects during the entire partnership life cycle. The tool A.PIE (Airline Partnership Intensity Evaluator) supports the synergy audit and, which idiosyncratic to the airline industry, multidimensionally applies the deduced relationship of partnership intensity and synergy to the most salient partnership areas and functions. The present dissertation shapes understanding of the true drivers and complexities of today's airline partnerships. It proposes a circular, multidimensional and dynamic model, thus attempting to enhance the set-up, performance and output of horizontal airline collaboration. From this point of view it endeavours to fill the gap identified in contemporary airline partnership management and practice. / AFRIKAANSE OPSOMMING: Sien asb volteks vir opsomming

机票超售,即售出的機票多於飛機客艙座位的數量，已經作為“國際慣例“被航空公司廣泛採用。但是这种做法是有争议的，因為其容易導致航班超售，使得旅客被拒登機而滯留，影響航空公司的聲譽。在這篇論文中，我們使用逆向拍賣的機制尋找自願放棄登機資格的旅客以收回部份已預售的低端機票來滿足高端旅客的需求，并同時根據拍賣實現的結果來賠償被拒絶登機旅客。具體地說，我們建立一個二期的機票銷售模型，並且假定低端與高端旅客分別在第一第二個銷售期到來，而航空公司通過決定其在兩個銷售期的銷售策略，使得其利潤最大化。在模型中，航空公司可利用逆向拍賣的方法，要求低端旅客在購買機票的時候，提交一個其在因為航班超售時，自願放棄座位的赔偿要求。當航班超售時，航空公司可根據低端旅客的競投信息，從中挑選出價最低的旅客，通過滿足他們的賠償要求，收回他們的機票以滿足高端旅客的需求。我们发现我们的机制在大多数情况下，可以提高航空公司的利润，改善航班的登機效率，同时，也能滿足部份低端旅客通過改變計劃行程獲取賠償的需求。我們也會比較逆向拍賣機制與其他現有機制，例如固定價格補償機制。此外，我們也會就逆向拍賣機票銷售模型中的定價问题进行研究。 / With increasing applications of revenue management, airline companies often oversell their tickets. This practice is controversial because some passengers would not be able to board when the number of show-up customers exceeds the available seats. And this might make the affected customers upset and thus affect the future revenue of the airline. In this paper, we propose a new mechanism - a call-back auction, in which the passengers are asked to submit a bid to indicate the compensation they would like to receive for giving up their seats and changing their original flight schedule. This could provide the airline with information to select passengers with the lowest compensation requirements and also reduce the negative impact on customer relationship. We develop a model with booking limit decision and examine the impact of this call-back auction mechanism on the airline's profitability and compare it with other existing mechanisms such as fixed-price compensation. We find that our mechanism can lead to higher profit for the airlines in most cases. In this study, pricing issues are also examined. / Detailed summary in vernacular field only. / Zhong, Zhiheng. / Thesis (M.Phil.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 72-76). / Abstracts also in Chinese. / Table of Contents --- p.vii / Chapter 0 --- Notation / Chapter 1 --- Introduction --- p.1 / Chapter 2 --- Literature Review --- p.7 / Chapter 3 --- Call-back Auction --- p.13 / Chapter 3.1 --- The Concept --- p.13 / Chapter 3.2 --- Implementation --- p.14 / Chapter 4 --- A Two-Period Model with Call-back Auction --- p.19 / Chapter 4.1 --- Uniform Price Call-back Auction --- p.21 / Chapter 4.2 --- Numerical Examples --- p.27 / Chapter 4.3 --- First-price Call-back Auction --- p.35 / Chapter 4.4 --- Revenue Comparison --- p.39 / Chapter 4.5 --- Call-back Auction with Reserve Compensation --- p.41 / Chapter 4.6 --- Alternative Information Structure --- p.50 / Chapter 5 --- Endogenous High-fare Price --- p.59 / Chapter 5.1 --- Additive Demand Function --- p.60 / Chapter 6 --- Conclusion --- p.68 / Bibliography --- p.72

Master of Agribusiness / Department of Agricultural Economics / Jason Bergtold / Markets for alternative fuels are emerging and are of great interest to both public and private companies, as well as government agencies looking to differentiate fuel sources to achieve improved and sustainable operational efficiencies. This creates a growing need for innovation and an increased supply of biofuel feedstocks for bioenergy options such as bio-jet fuel. This thesis aims to assess the logistical feasibility of producing oilseed bio feedstocks and the practicality of building new crush facilities specifically for bio-jet fuel production in Kansas. A logistical optimization model is built by applying data to estimate the potential Kansas supply of rapeseed as a possible feedstock option; transportation and facility costs associated with building; and proposed crushing facility sites, by considering the estimated demand for bio-jet fuel within Kansas. The developed optimization model determined that even average yields per acre and modest adoption rates by farmers willing to incorporate rapeseed into their crop rotations could provide enough feedstock to supply one or two crushing facilities, depending on a variety of additional factors, including bio-jet fuel demand in Kansas. Sensitivity analysis was performed on key model factors and determined that the most influential factor on both size and number of proposed crushing facilities was the market demand for bio-jet fuel. Ultimately, further research is required to better understand the actual market demand for bio-jet fuel within Kansas and how competition or supply supplementation of other bio feedstocks can affect the size or number of proposed crushing facilities. There are currently six oilseed crushing facilities operating in Kansas; although all are dedicated to soybean or sunflower seed. Further studies may find these sites as viable alternative options to building new crushing facilities for a separate type of feedstock.
