Abstract:
Accurately representing the price-demand relationship is critical for the success of a price optimization system. This research first uses booking data from 28 U.S. hotels to investigate the validity of two key assumptions in hotel revenue management. The assumptions are: 1) customers who book later are willing to pay higher rates than customers who book earlier; and, 2) demand is stronger during the week than on the weekend. Empirical results based on an analysis of booking curves, average paid rates, and occupancy rates for group, restricted retail, unrestricted retail, and negotiated demand

Abstract:
The Genetic Algorithm (GA) is a popular global search algorithm. Although it has been used successfully in many fields, there are still performance challenges that prevent GA’s further success. The performance challenges include: difficult to reach optimal solutions for complex problems and take a very long time to solve difficult problems. This dissertation is to research new ways to improve GA’s performance on solution quality and convergence speed. The main focus is to present the concept of shadow price and propose a two-measurement GA. The new algorithm uses the fitness value to measure s

The purpose of this thesis is to develop an optimization model that chooses the optimal and price efficient combination of underlying assets for a equally weighted basket option. To obtain a price efficient combination of underlying assets a function that calculates the basket option price is needed, for further use in an optimization model. The closed-form basket option pricing is a great challenge, due to the lack of a distribution describing the augmented stochastic price process. Many types of approaches to price an basket option has been made. In this thesis, an analytical approximation o

Consequently, the emphasis of the system operation management has been shifted from the supply-side to the demand-side.

Abstract:
The air transportation market has been growing steadily for the past three decades since the airline deregulation in 1978. With competition also becoming more intense, airline companies have been trying to enhance their market shares and profit margins by composing favorable flight schedules and by efficiently allocating their resources of aircraft and crews so as to reduce operational costs. In practice, this is achieved based on demand forecasts and resource availabilities through a structured airline scheduling process that is comprised of four decision stages: schedule planning, fleet assi

Abstract:
Les marchés de l’électricité sont aujourd’hui en forte transformation, notamment du fait des efforts de libéralisation pour étendre la compétence de gestion du système électrique par le marché. C’est par exemple le cas avec la mise en place de prix nodaux pour gérer les congestions sur le réseau. Par ailleurs, le développement des moyens de production d’électricité d’origine renouvelable met en cause le fonctionnement du système électrique. Dans ce cadre, la question d’investissement pour un producteur éolien se complexifie. Sa rémunération est susceptible à court terme de passer d’un système

The thesis contains the theoretical basis for study of possibilities of pricing information goods. The source areas are microeconomics, marketing, competitive advantage and economics of information goods. The model of market is created with constraints defined on the ground of theoretical basis. The thesis analyzes requirements that define the system that supports the choice of pricing strategy. It includes detailed design of the prototype of such system. The prototype is designed with robustness because of the future improvements. The design describes the prototype's input parameters and thei

There are many real cases where a company needs to determine the price of its products so as to maximise its revenue or profit.<p>To do so, the company must consider customers' reactions to these prices, as they may refuse to buy a given product or service if its price is too high. This is commonly known in literature as a pricing problem.<p>This class of problems, which is typically bilevel, was first studied in the 1990s and is NP-hard, although polynomial algorithms do exist for some particular cases. Many questions are still open on this subject.<p><p>The aim of this thesis is to investiga

Abstract:
Le Min-up/min-down Unit Commitment Problem (MUCP) consiste à trouver un plan de production de coût minimum pour un ensemble d’unités de production électrique sur un intervalle de temps discrétisé. A chaque pas de temps, la production totale doit satisfaire la demande prévue. Chaque unité respecte des temps minimum de marche et d’arrêt. Nous montrons que le MUCP est fortement NP-difficile, mettant ainsi en valeur l’impact du couplage dynamique des contraintes de demande sur la difficulté du problème. Pour appréhender cette difficulté, nous introduisons les inégalités interval up-set, généralisa

Abstract:
NP-hard problems of higher-dimensional orthogonal packing are considered. We look closer at their logical structure and show that they can be decomposed into problems of a smaller dimension with a special contiguous structure. This decomposition influences the modeling of the packing process, which results in three new solution approaches. Keeping this decomposition in mind, we model the smaller-dimensional problems in a single position-indexed formulation with non-overlapping inequalities serving as binding constraints. Thus, we come up with a new integer linear programming model, which we su
