How The 1996 Hotel Majestic agreement may explain a future PP/CiU relationship in Madrid

Some historians have argued that 1996 marked a ‘second transition’ for Spain because of the return to power of the political right in Madrid and that the relationship and eventual pact between the Partido Popular (PP) and Convergència i Unió (CiU) meant that the state could finally escape the ghosts of its Francoist past. For this research, face-to-face interviews were conducted with Catalan Members of Parliament who served under either José María Aznar or Jordi Pujol in Madrid or Barcelona. Drawing upon both interviews and other evidence, including the analysis of election results and the 1996 Hotel Majestic Agreement, the research seeks to provide a better understanding of the previous relationships between the PP and CiU and their leaders in order to understand what lessons might be learnt that would contribute to anticipating and explaining possible future negotiations between the two parties. This is attempted by first examining the potential costs and benefits of political pacts between centre (Madrid) and periphery (Barcelona). Secondly, due to many interviewees making reference to Salvador Espriu’s work La Pell de Brau, the three routes of Espriu’s Catalan nationalism are put into the context of the political pacts. Finally, the likelihood of future agreements between PP and CiU are hypothesized, not only how those agreements may (or may not) come about, but also, what might the result of those negotiations be. Ultimately, it is concluded that the benefits of the Hotel Majestic Agreement outweighed the costs, thus leaving the door open for future negotiations, even if some of those interviewed disagreed.

Sistema de reserves hoteleres on-line, basat en el protocol de comunicació OTA

L’origen d’aquest projecte neix en la necessitat de crear un sistema de reserves hoteleres on-line integral i amb connectivitat amb altres sistemes de reserves. S'ha optat pel protocol de comunicació OTA(Open Travel Alliance), es tracta d'un protocol de comunicació XML ideat per empreses del sector turístic dels Estats Units per la necessitat comuna d’unes especificacions tècniques que permetessin la comunicació electrònica de la informació

The customer valuations game as a basis for revenue management

I describe the customer valuations game, a simple intuitive game that can serve as a foundation for teaching revenue management. The game requires little or no preparation, props or software, takes around two hours (and hence can be finished in one session), and illustrates the formation of classical (airline and hotel) revenue management mechanisms such as advanced purchase discounts, booking limits and fixed multiple prices. I normally use the game as a base to introduce RM and to develop RM forecasting and optimization concepts off it. The game is particularly suited for non-technical audiences.

Equivalence of piecewise-linear approximation and Lagrangian relaxation for network revenue management

The network revenue management (RM) problem arises in airline, hotel, media,and other industries where the sale products use multiple resources. It can be formulatedas a stochastic dynamic program but the dynamic program is computationallyintractable because of an exponentially large state space, and a number of heuristicshave been proposed to approximate it. Notable amongst these -both for their revenueperformance, as well as their theoretically sound basis- are approximate dynamic programmingmethods that approximate the value function by basis functions (both affinefunctions as well as piecewise-linear functions have been proposed for network RM)and decomposition methods that relax the constraints of the dynamic program to solvesimpler dynamic programs (such as the Lagrangian relaxation methods). In this paperwe show that these two seemingly distinct approaches coincide for the network RMdynamic program, i.e., the piecewise-linear approximation method and the Lagrangianrelaxation method are one and the same.

A new compact linear programming formulation for choice network revenue management

The choice network revenue management model incorporates customer purchase behavioras a function of the offered products, and is the appropriate model for airline and hotel networkrevenue management, dynamic sales of bundles, and dynamic assortment optimization.The optimization problem is a stochastic dynamic program and is intractable. A certainty-equivalencerelaxation of the dynamic program, called the choice deterministic linear program(CDLP) is usually used to generate dyamic controls. Recently, a compact linear programmingformulation of this linear program was given for the multi-segment multinomial-logit (MNL)model of customer choice with non-overlapping consideration sets. Our objective is to obtaina tighter bound than this formulation while retaining the appealing properties of a compactlinear programming representation. To this end, it is natural to consider the affine relaxationof the dynamic program. We first show that the affine relaxation is NP-complete even for asingle-segment MNL model. Nevertheless, by analyzing the affine relaxation we derive a newcompact linear program that approximates the dynamic programming value function betterthan CDLP, provably between the CDLP value and the affine relaxation, and often comingclose to the latter in our numerical experiments. When the segment consideration sets overlap,we show that some strong equalities called product cuts developed for the CDLP remain validfor our new formulation. Finally we perform extensive numerical comparisons on the variousbounds to evaluate their performance.

On the tractability of the piecewise-linear approximation for general discrete-choice network revenue management

The choice network revenue management (RM) model incorporates customer purchase behavioras customers purchasing products with certain probabilities that are a function of the offeredassortment of products, and is the appropriate model for airline and hotel network revenuemanagement, dynamic sales of bundles, and dynamic assortment optimization. The underlyingstochastic dynamic program is intractable and even its certainty-equivalence approximation, inthe form of a linear program called Choice Deterministic Linear Program (CDLP) is difficultto solve in most cases. The separation problem for CDLP is NP-complete for MNL with justtwo segments when their consideration sets overlap; the affine approximation of the dynamicprogram is NP-complete for even a single-segment MNL. This is in contrast to the independentclass(perfect-segmentation) case where even the piecewise-linear approximation has been shownto be tractable. In this paper we investigate the piecewise-linear approximation for network RMunder a general discrete-choice model of demand. We show that the gap between the CDLP andthe piecewise-linear bounds is within a factor of at most 2. We then show that the piecewiselinearapproximation is polynomially-time solvable for a fixed consideration set size, bringing itinto the realm of tractability for small consideration sets; small consideration sets are a reasonablemodeling tradeoff in many practical applications. Our solution relies on showing that forany discrete-choice model the separation problem for the linear program of the piecewise-linearapproximation can be solved exactly by a Lagrangian relaxation. We give modeling extensionsand show by numerical experiments the improvements from using piecewise-linear approximationfunctions.

Evaluación y plan de actuación en materia de Prevención de Riesgos Laborales del Hotel Tanit (Benidorm)

El presente documento es un proyecto de intervención en el marco de la prevención de riesgos laborales en un hotel de tres estrellas de la localidad turística de Benidorm. A partir de un análisis exhaustivo de las necesidades de la organización, sus características intrínsecas, su modelo de gestión de la prevención de riesgos laborales, y una evaluación específica de cuatro puestos de trabajo, se pretende comprobar el funcionamiento de la gestión de la prevención, con el objetivo de proponer aquellas actuaciones que puedan mejorarlo. Para llevar a cabo dicha labor, se empleará una metodología analítica extraída de las guías técnicas del Instituto Nacional de Seguridad e Higiene en el trabajo (INSHT en adelante), que contemplan modelos y metodologías de evaluación ampliamente contrastados como el modelo de demanda-control-apoyo social de Robert Karasek, desarrollado por la metodología ISTAS21 de la NTP 604 del INSHT, o la Guía Técnica de pantallas de visualización de datos (PVD) del INSHT desarrolladora del RD 488/1997.El proyecto pretende de esta manera alcanzar unas conclusiones acordes a la fiabilidad de la metodología empleada, y de esta forma proponer actuaciones preventivas correctoras para los factores de riesgo hallados durante la evaluación de los puestos de trabajo, y que se ajusten en todo momento a los requerimientos legales vigentes en materia de prevención de riesgos laborales.Finalmente, el proyecto propondrá a modo de conclusiones la actualización del Plan preventivo con el que cuenta la empresa, en base a los descubrimientos hallados durante la investigación, así como una serie de acciones dirigidas a la satisfactoria integración de la actividad preventiva dentro del modelo de gestión de la empresa.
