Dissertations / Theses on the topic 'Airlines Decision making'

Fractional aircraft ownership programs offer companies and individuals all the benefits of owning private jet, such as safety, consistency, and guaranteed availability, at a fraction of the cost of owning an aircraft. In the fractional ownership model, the partial owners of an aircraft are entitled to certain number of hours per year, and the management company is responsible for all the operational considerations and making sure an aircraft is available to the owners at the requested time and location. This thesis research proposes advance optimization techniques to help the management company to optimally operate its available resources and provides tools for strategic decision making. The contributions of this thesis are: (i) The development of optimization methodologies to assign and schedule aircraft and crews so that all flight requests are covered at the lowest possible cost. First, a simple model is developed to solve the crew pairing and aircraft routing problem with column generation assuming that a crew stays with one specific aircraft during its duty period. Secondly, this assumption is partially relaxed to improve resource utilization by revising the simple model to allow a crew to use another aircraft when its original aircraft goes under long maintenance. Thirdly, a new comprehensive model utilizing Benders decomposition technique and a fleet-station time line is proposed to completely relax the assumption that crew stays with one specific aircraft. It combines the fleet assignment, aircraft routing, and crew pairing problems. In the proposed methodologies, real world details are taken into consideration, such as crew transportation and overtime costs, scheduled and unscheduled maintenance effects, crew rules, and the presence of non-crew-compatible fleets. Scheduling with time windows is also discussed. (ii) The analysis of operational strategies to provide decision making support. Scenario analyses are performed to provide insights on improving business profitability and aircraft availability, such as impact of aircraft maintenance, crew swapping, effect of increasing demand by Jet-card and geographical business expansion, size of company owned aircraft, and strategies to deal with the stochastic feature of unscheduled maintenance and demand.

This thesis describes the development of a decision support tool for unplanned maintenance of aircraft at ramp time during airport operations. Ramp time is the time between an aircraft arrival and its next departure. Clearance of an aircraft for flight is controlled by aviation regulations. Therefore decisions regarding maintenance are taken by engineers who have to comply with the regulations that are governed outside the organizational structure of the airline. Unplanned maintenance also often disrupts the normal operational scheduling and leads to significant costs. Therefore, the decision support tool must include the relevant aviation regulations, be capable of rescheduling to minimise disruption and be able to optimise solutions based on cost. In this project an aircraft schedule is used to demonstrate the procedures. An assumed fleet of six airplanes fly between three cities. Consultation with aviation experts ensured the size of the fleet and operations are realistic. A regulation database was developed based on the Master Minimum Equipment List (MMEL) for the aircraft, and a computer programme was developed to provide different options that comply with the regulations and take into account scheduling disruption and costs. In certain cases the regulations allow an aircraft to fly with some components inoperable so long as backup systems can perform the tasks. It is possible then to postpone the maintenance until the aircraft arrives at a properly equipped airport, or until a longer scheduled stopover reduces the disruption to operations. To address the engineering aspects of the project, maintenance of a single component that appears in the MMEL for the chosen aircraft is considered. To plan maintenance following a failure, the cause of the failure needs to be identified. Only then can the resources and time required to repair the defect be defined. The programme validation has confirmed it is able to balance different aspects of decisions related to unplanned aircraft ramp maintenance. Although the programme is based on an assumed fleet operation, the structure of the programme will allow it to be applied to other fleet and route configurations.

This research is a comparative field study of the influence of societal culture on organization structure and process. Past empirical studies were used to dérive a framework incorporating four fundamental dimensions of cultural values: power, authority distance, group orientation, and cognitive orientation- From thèse dimensions, five configurations were identified which accounted for most of the organizations reviewed in previous field studies: the Autocracy, the Political Entourage, the Traditional Bureaucracy, the Modem Bureaucracy and the Consensus configuration.[...]
Cette recherche est une étude comparative de l’Influence de la culture sociale sur les structures et processus d’organisation.

Cinq configurations furent Identifiées à partir de ces dimensions et expliquèrent la plupart des organisations étudiées dans des ouvrages antérieurs: l’Autocratie. l’Entourage Politique, la Bureaucratie Traditionnelle, la Bureaucratie Moderne et la configuration du Consensus.[...]

Long-range demand planning and capacity management play an important role for policy makers and airline managers alike. Each makes decisions regarding allocating appropriate levels of funds to align capacity with forecasted demand. Decisions today can have long lasting effects. Reducing forecast errors for long-range range demand forecasting will improve resource allocation decision making. This research paper will focus on improving long-range demand planning and forecasting errors of passenger traffic in the U.S. domestic airline industry. This paper will look to build upon current forecasting models being used for U.S. domestic airline passenger traffic with the aim of improving forecast errors published by Federal Aviation Administration (FAA). Using historical data, this study will retroactively forecast U.S. domestic passenger traffic and then compare it to actual passenger traffic, then comparing forecast errors. Forecasting methods will be tested extensively in order to identify new trends and causal factors that will enhance forecast accuracy thus increasing the likelihood of better capacity management and funding decisions.

The inception of the low-cost carrier (LCC) into the UK in the early 1990s revolutionised passenger aviation. The now saturated short-haul market finds airlines increasingly manipulative of their business model, seeking to further differentiate their product offering from their rivals. With an abundance of airlines to choose from, the consumer is faced with what at times can be a complex decision-making process as to which airline to fly with. This research seeks through empirical research to identify key characteristics and attitudes of airline passengers (with particular emphasis upon LCCs) and the implications for pre-trip decision-making and airline choice. The study begins with an overview of the airline business models that dominate the UK passenger aviation sector, before introducing Birmingham Airport (BHX) as a case study airport on which part of the main findings of this research are based. A detailed literature review then seeks to offer insight to attitude formation and the decision-making process that facilitates behaviour, before examining the implications for airline choice. The fieldwork was undertaken in two stages with passenger decision-making explored through structured-interviews conducted with passengers in the airside departure lounges at BHX (n = 490). In addition, the attitudes of airline passengers were explored using an online attitudinal survey, distributed internationally to a self-selected sample (n = 307). The quantitative analysis of both strands of research suggests key differences exist in the decision-making processes and research methods employed by passengers’ of airlines operating different business models, but particularly for passengers of LCCs. Both socio-demographic and situational factors are identified as influential in decision-making and choice processes. Attitudes, based upon actual experience and social representation are also considered significant. The findings present a classification of airline passengers based upon the primary research and suggest further quantitative research should explore decision-making over time and in different situational contexts.

Background: Several crises have passed and today, the world is witnessing the pandemic Covid-19. As a consequence, society is affected at large where new insights and attitudes are born. Existing literature suggests that a crisis may be a crucial determinant in shaping one’s attitudes and actions, and therefore marketing needs to adapt to these new attitudes and expectations. Involving consumers' perception of this issue, together with companies’ views within the industry, lies the foundation for this research to investigate any changing consumer attitudes towards the airline industry during Covid-19. Purpose: The purpose of this study is to investigate how consumer attitudes have changed within the airline industry in Sweden due to the Covid-19 pandemic, applying both consumers’ and companies’ perspectives to provide managerial implications for marketers. Method: With an interpretive nature, the study is qualitative added by quantitative measures, hence stated as multi-method. Primary data is collected through an analytical survey and four semi-structured interviews.  Findings: Investigating attitudes from economic, social and environmental perspectives, the study concludes that consumer attitudes have changed in several perspectives while some attitudes stay consistent with pre-crisis attitudes, hence not directly affected by the crisis. The empirical findings are coherent with the conceptual framework, explaining the complexity of the tourism airline industry and how new attitudes that arise from the Covid-19 pandemic is a predictor of future behavior during the crisis, which may be useful for future crises to come.

Vi valde ämnet som handlar om möjligheten att få ett lågkostnadsflygbolag opererande på Karlstad flygplats därför att det är en intressant fråga om regionen skulle gynnas av ett lågkostnadsflyg eller inte så väl som flygplatsens existens. På senare tid har det i media också ofta framkommit att flygplatsen har ekonomiska problem.

Idén till vårt syfte uppkom efter att ha läst rapporten som Handelskammaren i Värmland skrev angående vikten av flygförbindelser till och från Karlstad flygplats för regionen. I den rapporten framkom det att det var önskvärt med ett lågkostnadsflyg från Karlstad flygplats.

Frågan kring ett lågkostnadsflyg från Karlstad Flygplats presenteras genom användning av teorier för risk, uppdragsgivare- uppdragstagareproblemet och beslutstagande. Alla dessa områden är sammanhängande.

Vi intervjuade Göteborg/Säve-, Stockholm/Skavstas-, Jönköpings/Axamo- och Smaland/Växjöflygplats för att få information om aktuell situation på respektive flygplats med eller utan opererande lågkostnadsflyg. Frågorna som ställdes var av liknande karaktär, men det utgjordes en skillnad mellan dem, beroende om de tillhörde gruppen som redan har lågkostnadsflyg eller om de önskar ha ett lågkostnadsflyg.

Vi fann likheter mellan flygplatserna och de ledandes uppfattning i frågan om lågkostnadsflyg. Det visade sig även att det för flygplatsen är kostsamt att ha ett lågkostnadsflyg opererande, men att det däremot är fördelaktigt för regionen. Utöver det bör risken delas mellan fler än en intressent. För att bli framgångsrik måste man göra uppoffringar och lätta på attityden till risk hos intressenterna.

We chose our topic, regarding the possibility to get a low-cost airline operating at Karlstad airport, because it is an interesting question whether the region could benefit from a low cost airline or not as well as the existence of the airport. And lately the airport has been discussed in media.

The idea to our purpose arose after having read the report by Wermland Chamber of Commerce regarding the importance of flight connections to and from Karlstad airport, for the region. In this report it appeared that it was desirable with a low-cost airline at Karlstad airport.

This topic is presented by applying theories about an interested party model, risk, agency theory, decision making and growth. All these areas are somehow connected.

We interviewed persons in managing positions at Göteborg/Säve, Stockholm/Skavsta, Jönköping/Axamo and Smaland/Växjö airport, who gave information about the actual situation at their airport respectively. The first two airports have operating low-cost airlines and the last two have not. We also interview partners in Värmland to get their view of the situation at Karlstad airport. The questions were roughly the same, with a difference made if they belonged to the group that has a low-cost airline or if they belonged to the group without a low-cost airline.

We found that there are similarities between the airports. And it turned out that having a low-cost airline operating at an airport is a costly business for the airport, but it seems to be advantageous for the region. And that the risk ought to be diversified between more than one interested parties. In order to be successful you have to make sacrifices and lighten up all parties’ attitudes to risk.

We develop a detailed, large-scale, airspace planning and collaborative decision-making model (APCDM), that is part of an $11.5B, 10-year, Federal Aviation Administration (FAA)-sponsored effort to increase U.S. National Airspace (NAS) capacity by 30 percent. Given a set of flights that must be scheduled during some planning horizon, we use a mixed-integer programming formulation to select a set of flight plans from among alternatives subject to flight safety, air traffic control workload, and airline equity constraints. Novel contributions of this research include three-dimensional probabilistic conflict analyses, the derivation of valid inequalities to tighten the conflict safety representation constraints, the development of workload metrics based on average (and its variance from) peak load measures, and the consideration of equity among airline carriers in absorbing the costs related to re-routing, delays, and cancellations. We also propose an improved set of flight plan cost factors for representing system costs and investigating fairness issues by addressing flight dependencies occurring in hubbed operations, as well as market factors such as schedule convenience, reliability, and the timeliness of connections. The APCDM model has potential use for both tactical and strategic applications, such as air traffic control in response to severe weather phenomenon or spacecraft launches, FAA policy evaluation, Homeland Defense contingency planning, and military air campaign planning. The model is tested to consider various airspace restriction scenarios imposed by dynamic severe weather systems and space launch Special Use Airspace (SUA) impositions. The results from this model can also serve to augment the FAAâ s National Playbook of standardized flight profiles in different disruption-prone regions of the National Airspace.

We develop and evaluate two significant modeling concepts within the context of a large-scale Airspace Planning and Collaborative Decision-Making Model (APCDM) and, thereby, enhance its current functionality in support of both strategic and tactical level flight assessments. The first major concept is a new severe weather-modeling paradigm that can be used to assess existing tactical en route flight plan strategies such as the Flight Management System (FMS) as well as to provide rerouting strategies. The second major concept concerns modeling the mediated bartering of slot exchanges involving airline trade offers for arrival/departure slots at an arrival airport that is affected by the Ground Delay Program (GDP), while simultaneously considering issues related to sector workloads, airspace conflicts, as well as overall equity concerns among the airlines. This research effort is part of an $11.5B, 10-year, Federal Aviation Administration (FAA)-sponsored program to increase the U.S. National Airspace (NAS) capacity by 30 percent by the year 2010. Our innovative contributions of this research with respect to the severe weather rerouting include (a) the concept of â Probability-Netsâ and the development of discretized representations of various weather phenomena that affect aviation operations; (b) the integration of readily accessible severe weather probabilities from existing weather forecast data provided by the National Weather Service (NWS); (c) the generation of flight plans that circumvent severe weather phenomena with specified probability levels, and (d) a probabilistic delay assessment methodology for evaluating planned flight routes that might encounter potentially disruptive weather along its trajectory. Given a fixed set of reporting stations from the CONUS Model Output Statistics (MOS), we begin by constructing weather-specific probability-nets that are dynamic with respect to time and space. Essential to the construction of the probability-nets are the point-by-point forecast probabilities associated with MOS reporting sites throughout the United States. Connections between the MOS reporting sites form the strands within the probability-nets, and are constructed based upon a user-defined adjacency threshold, which is defined as the maximum allowable great circle distance between any such pair of sites. When a flight plan traverses through a probability-net, we extract probability data corresponding to the points where the flight plan and the probability-net strand(s) intersect. The ability to quickly extract this trajectory-related probability data is critical to our weather-based rerouting concepts and the derived expected delay and related cost computations in support of the decision-making process. Next, we consider the superimposition of a flight-trajectory-grid network upon the probability-nets. Using the U.S. Navigational Aids (Navaids) as the network nodes, we develop an approach to generate flight plans that can circumvent severe weather phenomena with specified probability levels based on determining restricted, time-dependent shortest paths between the origin and destination airports. By generating alternative flight plans pertaining to specified threshold strand probabilities, we prescribe a methodology for computing appropriate expected weather delays and related disruption factors for inclusion within the APCDM model. We conclude our severe weather-modeling research by conducting an economic benefit analysis using a k-means clustering mechanism in concert with our delay assessment methodology in order to evaluate delay costs and system disruptions associated with variations in probability-net refinement-based information. As a flight passes through the probability-net(s), we can generate a probability-footprint that acts as a record of the strand intersections and the associated probabilities from origin to destination. A flight planâ s probability-footprint will differ for each level of data refinement, from whence we construct route-dependent scenarios and, subsequently, compute expected weather delay costs for each scenario for comparative purposes. Our second major contribution is the development of a novel slot-exchange modeling concept within the APCDM model that incorporates various practical issues pertaining to the Ground Delay Program (GDP), a principal feature in the FAAâ s adoption of the Collaborative Decision-Making (CDM) paradigm. The key ideas introduced here include innovative model formulations and several new equity concepts that examine the impact of â at-least, at-mostâ trade offers on the entire mix of resulting flight plans from respective origins to destinations, while focusing on achieving defined measures of â fairnessâ with respect to the selected slot exchanges. The idea is to permit airlines to barter assigned slots at airports affected by the Ground Delay Program to their mutual advantage, with the FAA acting as a mediator, while being cognizant of the overall effect of the resulting mix of flight plans on air traffic control sector workloads, collision risk and safety, and equity considerations. We start by developing two separate slot-exchange approaches. The first consists of an external approach in which we formulate a model for generating a set of package-deals, where each package-deal represents a potential slot-exchange solution. These package-deals are then embedded within the APCDM model. We further tighten the model representation using maximal clique cover-based cuts that relate to the joint compatibility among the individual package-deals. The second approach significantly improves the overall model efficiency by automatically generating package-deals as required within the APCDM model itself. The model output prescribes a set of equitable flight plans based on admissible trades and exchanges of assigned slots, which are in addition conformant with sector workload capabilities and conflict risk restrictions. The net reduction in passenger-minutes of delay for each airline is the primary metric used to assess and compare model solutions. Appropriate constraints are included in the model to ensure that the generated slot exchanges induce nonnegative values of this realized net reduction for each airline. In keeping with the spirit of the FAAâ s CDM initiative, we next propose four alternative equity methods that are predicated on different specified performance ratios and related efficiency functions. These four methods respectively address equity with respect to slot-exchange-related measures such as total average delay, net delay savings, proportion of acceptable moves, and suitable value function realizations. For our computational experiments, we constructed several scenarios using real data obtained from the FAA based on the Enhanced Traffic Management System (ETMS) flight information pertaining to the Miami and Jacksonville Air Route Traffic Control Centers (ARTCC). Through our experimentation, we provide insights into the effect of the different proposed modeling concepts and study the sensitivity with respect to certain key parameters. In particular, we compare the alternative proposed equity formulations by evaluating their corresponding slot-exchange solutions with respect to the net reduction in passenger-minutes of delay for each airline. Additionally, we evaluate and compare the computational-effort performance, under both time limits and optimality thresholds, for each equity method in order to assess the efficiency of the model. The four slot-exchange-based equity formulations, in conjunction with the internal slot-exchange mechanisms, demonstrate significant net savings in computational effort ranging from 25% to 86% over the original APCDM model equity formulation. The model has been implemented using Microsoft Visual C++ and evaluated using a C++ interface with CPLEX 9.0. The overall results indicate that the proposed modeling concepts offer viable tools that can be used by the FAA in a timely fashion for both tactical purposes, as well as for exploring various strategic issues such as air traffic control policy evaluations; dynamic airspace resectorization strategies as a function of severe weather probabilities; and flight plan generation in response to various disruption scenarios.

Airlines have endured a prolonged period of intense competition with the advent of deregulation in 1978. Market innovations and price-cutting dramatically expanded the number of travelers utilizing the national air transportation network. Bankruptcies and mergers reduced the number of contestants in the industry and eventually produced four national carriers controlling 80-85 percent of the passengers and routes. This new market power of the dominant airlines is resulting in industry changes designed to reduce operational uncertainty but is also having detrimental effects on many airports, particularly the smallest airports. This study employs qualitative and quantitative methods to explore the viability of the nation’s smallest primary commercial service airports. Three journal articles are fused in examining different aspects of the viability question. In Article 1, a longitudinal comparative analysis presents historic growth patterns for various sized airports during deregulation and reveals a distinctly lower growth rate for nonhub airports than their larger rivals. Even with a burgeoning market for travelers, growth for nonhub airports was anemic and the industry experienced massive passenger migration to the 60 largest airports. Article 2 addresses the topic of consumer switching, expands on extant literature with qualitative analyses, and proposes a theoretic, conceptual framework of four primary types of traveler purchasers. Each traveler type has its own distinct switching rationale and creates leakage patterns contoured to the features of their preferred airport. Building on the migration and switching findings of the first two articles, Article 3 explores converging market conditions and factors that are threatening future airline service for dozens of the smallest airports. By extracting findings from contemporary research, a comparative analysis of airports identifies 33 airports that face the highest risk of losing air service. The explanatory model places the airports in rank order by weighting various threat criteria. Qualitative interviews of air service professionals offer insider observations generally not known to the public, confirm observations found in existing research and verify that market forces are acting to reduce the number of airports in the network. The key contribution of the three articles of the thesis is its description of how key actors (firms, customers, agencies) interact and respond to policy decisions that have unintended consequences to small airports and their regional economies. There are predictable patterns in the relational linkages of these actors that contribute to our understanding of how a particular industry evolves under various pressures and how it interacts with factors outside the industry. The preponderance of the evidence from this study reveals that current market trends are generally caustic to the continued operation of small airports. Industry experts are reticent in acknowledging that the next phase of deregulation is underway with the consolidation of the nation’s nonhub airports.

Title of Thesis: Decision- Making Analysis of The Carter Total Pages:376 Administration's Airlines Deregulation Policy Key word: regulation; deregulation; decision-making process; Elite Theory and Organizational Decision-Making Model Name of Institute: Graduate Institute of American Studies, Tamkang University Graduate Date: December, 1999 Degree Conferred: Doctor of Law Name of Student: Chi Yeh Yung Advisor: Dr. Thomas B. Lee 容 繼 業 李 本 京 博士 Abstract: The main purpose of this study is to analyze the factors and their interrelations of how airlines deregulation policy came to be an acceptable reform alternative of President Jimmy Carter's administration during the 1974 to 1978 period. The author employed the Crucial Case Study and Decision-Making Approach to conduct his research on the case of Airline Deregulation. The author also adopts the decision-making approach presented by David Easton, James March, Herbert Simon, James Robinson and Roger Marjak to sort out the factors influencing the airline deregulation policy decision-making. Besides, the author integrates those factors into four major cluster analyses: domestic politics, individual factors of decision-makers, decision-making process, output and feedback. To analyze the decision-making process of the Carter administration's airlines deregulation policy, the author invokes two sets of heories. The first one is Group Theory. The second set of theories is Elite Theoryand the Organizational Decision-Making Model. The result of this study indicated that President Carter, when he was first inaugurated as the President, decided to deregulate the airlines industry base on his belief in the so called the free market economic system. In addition, the factors of "idea changed " 、 "deregulation coalition formed" and "the influence power of Economic Elite" are found as the major factors in contributing to and influencing Carter's decision-making. Moreover, the study states that the Group Theory, Elite Theory and Organizational Decision-Making Model were effective in explaining the decision-making process of the Carter administration's airlines deregulation policy. Finally, suggestions are made for future study in the aspect of evaluating the airlines deregulation policy toward the new environmental development challenge of airlines industry.

Due to Asia’s booming aviation market, this study aims to develop a decision making model for leasing or purchasing an aircraft from airline’s point of view to meet the increased market demand based on the current operating aircraft fleet. Different from a large-scale aircraft fleet planning, this study only considers the acquisition of an additional aircraft. Therefore, the size of increased demand, the characteristics of the potential air routes to fly with, the current operating aircrafts, and the financial feasibility of the target airline company should be considered. To do so, this study uses the Analytic Hierarchy Process (AHP) method to develop the analytical framework. A total of five criteria are proposed: Financial feasibility, Demand Compatibility, Aircraft Compatibility, Performance Reputation, Environmental Protection Reputation, each of which has two to four associated sub-criteria. To obtain the weights, a total of 10 experts with rich experiences in aircraft acquisition, management and maintenance are interviewed. Results show that the summated weights of the first three criteria, i.e. Financial feasibility, Demand Compatibility, Aircraft Compatibility, exceed 0.7, explaining the importance and dominance of these criteria. To demonstrate the applicability of the proposed AHP model, a case study on an airline is conducted. A total of eight alternatives are compared, including four candidate aircraft types: Airbus 320, Airbus 330, Boeing 737, and Boeing 787 and two acquisition methods, lease or purchase. Additionally, one-stage decision (consider all criteria) and two stage decision processes (use of four criteria, except for Financial feasibility, to evaluate the type of aircraft and then use of Financial feasibility criteria to decide lease or purchase the chosen aircraft type). The evaluation results of two decision processes consistently show that to purchase the Airbus 320 is the best alternative for the target airline.

Air transportation business is all about transporting people and shipping cargos with airplanes to the planned destinations. In recent years, the use of air transportation has becoming more popular with ever increasing business volume and high growth awareness providing people with more variety of selection on which carrier to use for their intended businesses. As such, for air transportation enterprise to sustain their business within the global competitive market and under tough economic environment, it is critical to have good business strategy. Strategies including equipment improvement, enhancing safety and service training, and increasing service quality to achieve customers’ highest level of satisfaction need to be considered. To successfully implement these strategies would require all service workers’ full devotion, supervision, management, and services. For that, cabin manager play a key role. A good supervisor can create a pleasant working environment for all cabin crew members such that customers can receive satisfactory services. Therefore, selecting optimal cabin managers is one of the most important tasks for the air transportation service team. Through the literatures review and experts interview, we obtain 3 criteria and 18 sub-criteria to construct the hierarchical structure, also we obtain hierarchichy structure for selecting optimal cabin managers. 3 criteria are language skills, compressive capacity, service skills, training performance, crisis management, professional knowledge, teamwork, coordination, leadership, problem solving, upright, loyalty, good character, pay attention to performance, be treated equally, service enthusiasm, emotional adjustment, and identify organizational culture. This study uses China Airlines as an example to illustrate the decision making process of selecting cabin managers.

Disruption Management in the airline industry plays an important role in airline operations. The goal of disruption management is to minimize the costs associated with disruptions while returning to the original schedule. Methodologies using advanced tabu search (TS) were investigated to solve two flight rescheduling problems: the aircraft grounding problem and the reduced station capacity problem. The objectives of both problems were to minimize the schedule recovery costs associated with flight schedule modifications and deviations from the original route, which are composed of the sum of delay costs, cancellation costs and aircraft route swap costs. Reflecting the cost of the deviation from the original route, the swap cost was modeled as a non-linear function of the swaps of aircraft between routes. In each problem, a stand-alone tabu search approach was constructed to holistically minimize the sum of the cost of delays, cancellations and swaps. Next a hybrid method which combined a time-space network flow model with side constraints and a limited tabu search was created which attacked the problem in two steps: first, the total cost of delays and cancellations was minimized by the network flow model; second, a limited tabu search was conducted to minimize the number of swaps. A second hybrid method was then developed, which utilized the result from the first hybrid method as starting solution for the stand-alone tabu search. The results of the experiments performed with the hybrid methods clearly indicate that integrating TS with classical optimization methods has marked potential for improving the results of a disruption management technique.

Air transportation has become the most efficiency and important way of transportation nowadays. Since Wright brothers invented aircraft in 1903, air transportation continues on change its role in military, commercial or any other purposes. Those fields also give air transportation different direction at the same time. Commercial is the most significant among all those fields, no matter on range, capacity, speed or comfort. Air transportation equipments are major tool for airliner to make and manage their money. For this reason, fleet development plays an important role on commercial airlines’ future plan. Different manufacture offers different selections of aircrafts; each aircraft has its features and limitations. Therefore, this research will start from current fleet of for domestic airlines (UNI Air, Mandarin Airlines, Far Eastern Air Transport, and TransAsia Airways), using those factors effect aircraft selection mentioned in this research to interpret their aircraft chosen strategy when they establish their current fleet. At the same time, we will estimate the best choices of future fleet development for all four domestic airlines by analyze logistic, training, maintenance, passenger preferences, and type of aircrafts (jet/propeller, single/multi engines). This research focuses on the time period start from Jan. 1980 to Dec. 2002, data collected by questionnaire filled by above four airlines. Collected data is calculated according to Fuzzy theory to estimate the best choice of future fleets for each airline.

Flight safety plays an important role at air transportation industry. After investigating the latent factors behind accidents, safety culture and safety management have been considered as two of the influential concerns to flight safety. Reason argued that safety culture could be subdivided into five sub-culture. Among them, the just culture only has few practical studies to help the implementation. Therefore, substantive research of just culture is required to strengthen the industrial safety culture. After interviewing airliners’ experts, we found just culture is strongly associated with companies’ punishment system which is usually used while employees made mistakes. Similar events or human errors might receive different penalties in different companies because of differences of organizational culture, traditions and thoughts of the top executives. However since a reasonable and convincible punishment given to the employees has strong impacts to the virtue or vice of just culture, this study aims to establish a culpability decision making guidelines that fits with the concepts of just culture. Management thoughts about punishments of Taiwan airlines will be extracted via AHP method in line with the national jurisdiction conditions. The results verified a comparison of survey data between three domestic airlines. Among all airlines, the timing of reporting and systematic failures were rated as the most important factors of all. Managers hope employees could demonstrate a positive attitude, take actions to help alleviating negligence or potential problems. Systematic or environmental factors behind the human errors should be took into account as well before leave entire attribution to the relevant personnel. Other criteria included in this study are the reoffending of similar behavior, the company''s losses and impacts, and the past work performance of relevant personnel. The differences of the weight ratings of the criteria between three operators were compared to explore their appropriateness for just culture. This study can be used to help building a more reasonable and convincible culpability system for the Taiwan aviation industry, to help adopting and promoting safety culture, and to enhance flight safety at the final.

This study takes the China Airlines Park BOT (Build, Operate and Transfer) development project at the Taoyuan International Airport as an example and an Analytical Network Process (ANP) is used to assess the multi-criteria decision-making method. Aimed at the feasible initial study stage of the project life cycle, this study conducted an assessment of the criteria for project financing and established a final decision assessment model. To promote participation, the BOT model, in addition to reducing the financial burden on the government, combines adequate civil financial and advanced management concepts and techniques to both conduct and promote regional and peripheral industrial development. It also enhances employment opportunities and public interest to achieve a winning situation for the public, the business sector and the government. Among the complex elements of assessment, the most critical and influential decision factor is the financial assessment that is closely related to the overall development project and has significant impact on the success or failure of each stage of the project life cycle. In the early stages of project development, civil institutions, in addition to presentation of the concept in writing and studying the feasibility report for the initial stage in accordance with the provisions of the Procurement Act, Promotion of Participation Act, etc., also focus on the main financial analysis of the project. From the customized planning of the entire project, the change in the interest and exchange rates, inflation, cash flow forecasts, operating recovery period, up to the final sensitivity analysis and other criteria, all affect the final success or failure of the project. In the ANP multi-criteria decision-making assessment, there are four basic models: simple type, feedback type, second-order network model and complex network model. The second-order network procedural method was used in this study and happened to be in line with the decision making needs for the project’s financial assessment of civil institutions to participate in the public construction. The biggest difference between ANP and AHP (Analytic Hierarchy Process) lies in AHP’s assumption that all assessment criteria are independent, while ANP in the assessment criteria sets the dimensions as having internal or external dependencies. The results of the ANP method used to conduct the decision-making analysis are more in line with the needs of comprehensive assessment and logical thinking. Due to their more diversified and demanding nature, the project financial assessment was developed in accordance with the Promote Participation Act and involved the public interest. Therefore, the overall planning, cost of the project development, and financial investment were more holistic and did not just consider single interests independently. This study refers to the literature on the application of ANP and promotes the participation project-related reports that have been implemented in the country. The four main criteria structure (benefits, opportunities, costs, and risks) of the second-order network procedural method of the ANP was adopted for the study analysis. Although this study used the case of BOT as an example, the results have shown that this analytical model, according to its attributes and characteristics, can be used in other types of development projects. Due to its wide range of coverage and greater reliability, it can also provide reference for other studies, and it is expected to enhance future studies and in-depth research.

Since the deregulation of the airline industry in 1987, airline’s market in Taiwan is growing fast. Airlines form alliances with each other expand routes and enhance their competitivity. Currently there are five alliances such: Star Alliance, One World, Wings Alliances, Sky Team and Qualiflyer. In recent years, the mergering among airlines is prevailing. There are two types of alliance in practice: code-sharing, and mergering. This study applies game theory to analyze competition among airlines. The result could provide the airlines’ managers to evaluate the effectiveness of their agreement. There are three major components of the payoff function：the demand model, the market share model, and the cost model. Based on the estimated payoff function, this research applies the game theory to find the most profitable airfares under different cooperative scenarios. Given the optimal airfares, the corresponded payoff values of airlines are obtained. A case study of using survey data collected from passengers flying from Taipei to Amsterdam, from Taipei to San Francisco, and from Taipei to Sydney is presented to verify the effectiveness of the model. In addition, AHP and TOPSIS are selected to evaluate the decision process of making. Based on the test result, operation performance is the most important factor and the other important factors in descending order are finance performance, route overlap, maintain integration, and personnel integration.

The privatized nature of the current airline industry has increased its competitiveness. Stringent competition among airline carriers has led to the formation of alliances, which encompass all aspects of operation. More than just a contractual agreement to cooperate, such alliances encompass joint promotion or procurement to increase sales volume, reduce overhead costs, coordinate flight schedules to harmonize connections, and provide passengers with improved travelling pleasure, efficiency and time savings. The growing strength of alliances has motivated non-allied airlines to consider joining such an alliance. This work presents two analytical solutions based on use of airline data. Specifically, once an airline decides to join an alliance, either a fuzzy multi-criteria decision analysis is performed under selected key factors or discrimination analysis is performed to forecast airline clusters by collecting specific airline data. Finally, importance-performance analysis is perform to devise entry strategies into different alliances.

Abstract Domestic airlines have competed more fiercely since Taiwanese government deregulated the domestic airline market in 1987. Many airlines are looking for the ways to enhance their competitiveness. The purpose of this research is to establish a rigorous methodology to gauge competitiveness of airlines, and analyze key factors that influence the competitiveness of airlines. In addition, we can compare the competitiveness between airlines by multi-criteria evaluation method. Taiwan’s domestic airlines are used as an empirical study to examine the effectiveness of the methodology developed. According to the literature, we define competitiveness as utilizing the resources more efficiently, improving customers and stakeholders’ value sustainably. Besides, we establish five constructs to measure the competitiveness of airlines, the management ability, price competitiveness, service quality, productivity, and cost competitiveness. Then we conduct a sensitivity analysis to analyze to what degree each construct affects. The result shows that service quality and the management ability are the critical constructs. In other words, these two constructs affect the competitiveness more seriously. Second, the weights of criteria used in traditional evaluation methods are often determined by decision makers with their own judgements. The appropriateness of the weights are seldom discussed which might lead to erroneous results. Therefore, we provide a rigid and logical method to determine the weights. The result shows that Entropy method is suitable for Weighted Product Method (WPM) and TOPSIS. Besides, if the decision makers are lack of confidence in the weights of evaluation, they are suggested to use WPM. Finally, this study integrates the theory of competitiveness and Multiple Attribute Decision Making to establish a model comparing airline competitiveness between the year 1992 and 1997. When companies improve their management abilities, the ranks of their competitiveness will raise considerably. It is the same as the statement provided. The main contributions of this study are summarized as follows: 1.Developing a rigorous methodology to analyze the competitiveness of the airlines. 2.Defining the competitiveness of domestic airlines with measurable indices. 3.Understanding the nature of competitiveness and the complexities of the findings resulted from the study.

Aviators are still the final wall to solve abnomal flight condition in advanced aviation environment. For prosperous progressive travelling and aviation market, airliners are short of pilots. Airline pilots are different from other profession. It cost at least 10 million to eduate pilot. To realize the competency of airline pilots and give proper training would help them safely accomplish each flight duty. The purpose of the research is to find critical competency of airline pilots through critical incident and formulate related pilot selection criteria. These findings are 5 groups and 29 critical competency criteria. The 5 groups are aviation knowledge, learning skills, personality, willing to learning and job accomplishment and responsibility. And 29 critical competency are made of basic knowledge, new aviation knowledge and aviation environment, aircraft system knowledge, flight operation process, metrology knowledge aviation regulation knowledge, the skill of grasping knowledge, the skill of accepting training, CRM communication, flying skill, the skill of creating work atmosphere, the skill of logic reasoning, alertness, stability, hard to getup set, no rush, calmness, obey ness, punctuality , willing to admit error and correct it, humbleness, self-responsible, duty-responsible, safety-responsible, service, accomplishment, job eager, the desire of new information and eager of knowledge. Furthermore, the research is to verify the validty of critical competency and pilot selection model. For critical competency, by using Flight Operation Monitoring (FOM) system, logic reasoning and stability are with significantly difference in two different groups. Meanwhile, the two different groups have no different opinion of critical competency ranking after Spearman’s test. As to the pilot selection model, airliner’s management who has pilot selection screening experience is invited to give priority evaluation of applicants. With Spearman’s test, the result shows that the pilot selection model is with useful value.
