Available in PDF, EPUB and Kindle. Book excerpt: In the airline industry, it is customary for carriers to offer a wide range of fares for any given seat in the same cabin on the same flight. In order to control the number of seats made available in each fare class, airlines practice what is called seat inventory control. Traditionally, airline seat inventory control has been the process of allocating seats among varies fare classes on a flight leg in order to maximize expected revenues. Reservations for travel on a flight leg are accepted based on the availability of a particular fare class on that flight leg. A passenger's ultimate destination, overall itinerary, or total revenue contribution to the airline is not taken into account. The typical route structure of a large airline, however, is built around a complex network of connecting flights. Maximizing revenues on individual flight legs is not the same as maximizing total network revenues. The objective of this dissertation is to address the seat inventory control problem at the network level, taking into account the interaction of flight legs and the flow of traffic across a network. Beginning with the traditional network formulation of the seat inventory control problem, practical approaches for actually controlling seat inventories at the origin-destination and fare class (ODF) level are first discussed. To avoid problems associated with forecasting ODF itinerary demand, network methods based on aggregated demand estimates are then presented. Taking the network seat inventory control problem one step closer to fit in with current reservations control capabilities, several leg-based heuristics are introduced. These heuristics take into account information about different ODF passenger demand and traffic flows while optimization and control of seat inventories remains at the flight leg level. In order to effectively measure the revenue potential of the different network seat inventory control methods introduced, an integrated optimization/booking process simulation was developed. Specific issues related to realistically modeling the booking process are discussed and the multi-period, computer-based, mathematical simulation described in detail. With the use of this integrated optimization/booking process simulation, the revenue impacts of the different network seat inventory control methodologies are then evaluated using real airline data for both a connecting hub network and multiple flight leg networks. Overall performance of each method is examined by comparing the revenue obtained with that of current leg-based control approaches and the maximum revenue potential given perfect information. The performance of the different methods evaluated varies with both the network and the actual demand patterns, however, significant revenue impacts over current seat inventory control approaches can be obtained. One approach which consistently performs well is a deterministic network approach in which ODF seat allocations are nested by shadow prices. Depending on the network structure, other leg-based OD control heuristics also perform well. The benefits of network seat inventory control are a function of the load factor across a network. Below an average load factor of about 85%, revenue impacts over effective leg-based control are non-existent. However, as the average load factor increases, revenue impacts on the order of 2-4% are obtainable.

Download or read book Air Travel Demand and Airline Seat Inventory Management written by Peter P. Belobaba and published by . This book was released on 1987 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many airlines practice differential pricing of fare products that share a common inventory of available seats on an aircraft. Seat inventory management is the process of limiting the number of seats made available to each fare class. The objective of both strategies is to maximize the total revenues generated by the mix of fare products sold for a flight. This dissertation first examines the evolution of airline marketing and seat inventory management practices. A demand segmentation model is developed to help explain current airline fare structures. A conceptual model of the consumer choice process for air travel is then presented, and extended to describe the airline reservations process and the probabilistic elements that can affect seat inventory control. A survey of current airline practice in this area revealed that seat inventory control is an ad-hoc process which depends heavily on human judgement. Past work on quantitative approaches has focused on large-scale optimization models that solve simple representations of the problem. A primary objective of this research was the development of a quantitative approach based on the practical constraints faced by airlines. The Expected Marginal Seat Revenue (EMSR) model developed in this thesis is a decision framework for maximizing flight leg revenues which can be applied to multiple nested fare class inventories. It is applied to a dynamic process of booking limit revision for future flight departures, and overbooking factors as well as fare class upgrade probabilities are incorporated. Examples of EMSR model results are presented, and a critical analysis of the demand assumptions and sensitivity of the model is performed. The EMSR model was implemented as part of an automated seat inventory control system at Western Airlines and tested on a sample of actual flights. Compared to flights managed by existing manual methods, flights for which fare class booking limits were set and revised automatically on the basis of the EMSR decision model carried more passengers at a lower yield, and generated higher total revenues.

Book excerpt: A well-studied problem in the literature on airline revenue (or yield) management is the optimal allocation of seat inventory among fare classes given a demand distribution for each class. In practice, the seat allocation decisions of one airline affect the passenger demands for seats on other airlines. In this paper we examine the seat inventory control problem under both horizontal competition (two airlines compete for passengers on the same flight leg) and vertical competition (different airlines fly different legs on a multi-leg itinerary). Such vertical competition can be the outcome of a code sharing agreement between airlines, for each airline sells seats on the partner airlines' flights but the airlines are unwilling, or unable, to coordinate yield management decisions. We provide a quite general sufficient condition under which a pure-strategy Nash equilibrium exists in these 'revenue management games', and we also compare the total number of seats available in each fare class with, and without, competition. Analytical results as well as numerical examples demonstrate that under horizontal competition more seats are protected for higher-fare passengers than when a single airline acts as a monopoly, while under vertical competition the booking limit may be higher, or lower, than the monopoly level, depending upon the demand for connecting flights in each fare class. Finally, we discuss revenue-sharing contracts that coordinate the actions of both airlines.

This book was released on 2012-12-06 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: When solving real-life engineering problems, linguistic information is often encountered that is frequently hard to quantify using "classical" mathematical techniques. This linguistic information represents subjective knowledge. Through the assumptions made by the analyst when forming the mathematical model, the linguistic information is often ignored. On the other hand, a wide range of traffic and transportation engineering parameters are characterized by uncertainty, subjectivity, imprecision, and ambiguity. Human operators, dispatchers, drivers, and passengers use this subjective knowledge or linguistic information on a daily basis when making decisions. Decisions about route choice, mode of transportation, most suitable departure time, or dispatching trucks are made by drivers, passengers, or dispatchers. In each case the decision maker is a human. The environment in which a human expert (human controller) makes decisions is most often complex, making it difficult to formulate a suitable mathematical model. Thus, the development of fuzzy logic systems seems justified in such situations. In certain situations we accept linguistic information much more easily than numerical information. In the same vein, we are perfectly capable of accepting approximate numerical values and making decisions based on them. In a great number of cases we use approximate numerical values exclusively. It should be emphasized that the subjective estimates of different traffic parameters differs from dispatcher to dispatcher, driver to driver, and passenger to passenger.

Book excerpt: This third edition of Straight and Level thoroughly updates the previous edition with extensive comments on recent industry developments and emerging business models. The discussion is illustrated by current examples drawn from all sectors of the industry and every region of the world. The fundamental structure of earlier editions, now widely used as a framework for air transport management courses, nonetheless remains unchanged. Part 1 of the book provides a strategic context within which to consider the industry's economics. Part 2 is built around a simple yet powerful model that relates operating revenue to operating cost; it examines the most important elements in demand and traffic, price and yield, output and unit cost. Part 3 probes more deeply into three critical aspects of capacity management: network management; fleet management; and revenue management. Part 4 concludes the book by exploring relationships between unit revenue, unit cost, yield, and load factor. Straight and Level has been written primarily for masters-level students on aviation management courses. The book should also be useful to final year undergraduates wanting to prepare for more advanced study. Amongst practitioners, it will appeal to established managers moving from functional posts into general management. More broadly, anyone with knowledge of the airline industry who wants to gain a deeper understanding of its economics at a practical level and an insight into the reasons for its financial volatility should find the book of interest.

This book was released on 1988 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Airlines have recently realized the importance of an effective seat inventory control system on revenues and profits. Yet, at the same time, there is a lack of practical optimization models for determining the number of seats to allocate to each origin-destination and fare class itinerary in an airline's network. In this thesis, several different mathematical models and optimization techniques for origin-destination seat inventory control are evaluated and compared. Each technique is applied to a small network with assumed demand levels and fares for each O-D/fare class combination. The techniques are then compared with respect to the differences in seat allocations and booking limits, fare class nesting order and total potential system revenue. The "optimal" seat allocation solution is found by the probabilistic linear programming technique, but actual use of such a method is impractical due to the size of its formulation and its distinct inventory solution, which is not compatible with the nested reservations systems of most major airlines today. The technique that seems to have the most potential as an efficient origin-destination seat inventory control method is a network based deterministic linear programming technique, with seat allocations nested according to shadow prices.

Available in PDF, EPUB and Kindle. Book excerpt: In an increasingly globalised world, despite reductions in costs and time, transportation has become even more important as a facilitator of economic and human interaction; this is reflected in technical advances in transportation systems, increasing interest in how transportation interacts with society and the need to provide novel approaches to understanding its impacts. This has become particularly acute with the impact that Covid-19 has had on transportation across the world, at local, national and international levels. Encyclopedia of Transportation, Seven Volume Set - containing almost 600 articles - brings a cross-cutting and integrated approach to all aspects of transportation from a variety of interdisciplinary fields including engineering, operations research, economics, geography and sociology in order to understand the changes taking place. Emphasising the interaction between these different aspects of research, it offers new solutions to modern-day problems related to transportation. Each of its nine sections is based around familiar themes, but brings together the views of experts from different disciplinary perspectives. Each section is edited by a subject expert who has commissioned articles from a range of authors representing different disciplines, different parts of the world and different social perspectives. The nine sections are structured around the following themes: Transport Modes; Freight Transport and Logistics; Transport Safety and Security; Transport Economics; Traffic Management; Transport Modelling and Data Management; Transport Policy and Planning; Transport Psychology; Sustainability and Health Issues in Transportation. Some articles provide a technical introduction to a topic whilst others provide a bridge between topics or a more future-oriented view of new research areas or challenges. The end result is a reference work that offers researchers and practitioners new approaches, new ways of thinking and novel solutions to problems. All-encompassing and expertly authored, this outstanding reference work will be essential reading for all students and researchers interested in transportation and its global impact in what is a very uncertain world. Provides a forward looking and integrated approach to transportation Updated with future technological impacts, such as self-driving vehicles, cyber-physical systems and big data analytics Includes comprehensive coverage Presents a worldwide approach, including sets of comparative studies and applications
