Competition and Schedule Padding in the US Airline Industry

Disclosure programs can help consumers with limited information about product quality make better purchase decisions. A quality disclosure mandate such as the On-Time Disclosure Rule in the U.S. that requires airlines to provide information on the quality of their products can be beneficial, but can also be counterproductive if it encourages airlines to act deceptively by “gaming” the system. If airlines care about public perceptions of their on-time record, they have an incentive to improve their on-time performance ranking by resorting to unscrupulous means such as padding their schedules beyond normal time required to absorb scheduling stochastic fluctuations. This study investigates the impact of competition on airline schedule padding. We construct a measure for schedule padding under different optimal flight time choices. Using different measures of market structure, we find that more competitive (concentrated) markets are subject to less (more) schedule padding.

SUBSTANTIATION OF METHODICAL APPROACHES TO DEFINING BORDERS OF SANITARY NOISE PROTECTION ZONES IN AERODROME SURROUNDINGS

Borders of noise protection zones for populated aerodrome surroundings have been defined with account of equivalent and peak noise levels from different types of airplane in control points, take-off and landing paths, taxiing, day and night airline schedule, lay of land and seasonal variations. The effort was accomplished in four stages. The first stage was choosing methods and parameters to be measured. The second was analysis of airline schedule and noise produced by airplanes. The third was calculation of equivalent and peak noise levels and the fourth was setting guidelines on drawing the noise protection zones in populated airdrome surroundings.

MODEL OPTIMISASI ROBUST PADA MASALAH PENJADWALAN DI MASKAPAI PENERBANGAN

Buku ini berisikan hasil-hasil penelitian penulis tentang metode yang dapat digunakan untuk membangun robust airline schedule, yaitu penjadwalan yang disusun sedemikian sehingga dapat meminimumkan propagasi delay ketika dioperasikan. Model model optimisasi yang telah dihasilkan terdiri dari model optimisasi untuk melakukan pergeseran jam keberangkatan penerbangan, model optimisasi pengalokasian slack, dan formulasi robust counterpart dari model pergeseran jam keberangkatan penerbangan.
