This BSc thesis introduces the development of an independent, standalone software, VisualSR2D, for the characterization of software roughness. The software is written in Matlab, can be installed in any Windows OS as an standalone application and is available under request. It is intended to be an alternative for Softgauges (National Physical Laboratory, UK), RPTB (Physikalisch-Technische Bundesanstal, Germany) and SMATS (National Institute of Standards and Technology, USA) in the study of surface roughness. The standard ISO 5436-2 is presented, the above mentioned alternative developments are analyzed and compared, best practices are gathered, and finally, the development and functionality of VisualSR2D is presented.

This paper presents a material demand forecasting to executive aircrafts modifications, the objective was to determinate a cadence of kits of materials in order reduce over stock, but also keeping the customer quality support. This work was motivated by the strong tendency that the market has to cut costs, especially those that do not add value to the product, waste. To solve the problem the Poisson probability distribution was used and also the error measures MPE, MAPE and MSE. At the end, after some adjustments, we found a satisfactory model for the problem

This work proposes a study on the materials selections and processes for the manufacture of aircraft and showing a methodology to reduce the manufacturing cost. The DFMA can be understood as a methodology that aims at reducing manufacturing and assembly costs and coupled with the increase of product quality through design simplifications. The most commonly material used in the manufacture of aircraft is aluminum alloys due to these possess great structural strength, good elasticity, and being stainless having a low specific weight (about 1/3 that of steel), reducing the weight of the aircraft. A case study in which an operation in the process of verifying the quality was generating unnecessary costs time / man for the company was also developed. The problem solution was simple, just removing the attachment process. It was found that the DFMA methodology is extremely important for the simplification of processes and projects, contributing to the reduction of manufacturing costs of aircraft

Given the competitive reality of the globalized market, companies are compelled to develop strategic aspects of the management process, in order to ensure their survival. Among the strategic aspects is the price formation process, whose reasoning occurs mainly of adoption through cost system. Knowledge of costs and expenses provides conditions for the company to position itself strategically in the market, being able to follow the price of competition and sometimes even surpass them, called, more and more attention with regard to price formation. This study aims to identify the best price to be transferred to the market. To this end, were approached concept of pricing and its components, their strategies and pricing objectives, as well as the influence of demand on price formation, as well as the added value the brand and quality; and even a careful analysis of the price established by the said company in the service offered. We used the method of literature review and case study in the company ESA international aeronautical industry. Thus, we sought to explain about the main concepts for pricing in order to support decision making

In this article an index decomposition methodology is used to estimate the effect of intersectorial and intrasectorial changes in explaining the 38% reduction in industrial energy intensity in the Basque Autonomous Community from 1982 to 2001. Period-wise additive decomposition results show that (1) the decline is fully explained by intrasectorial changes and that (2) intersectorial changes have not contributed to reduce but to increase the energy intensity of the Basque industrial sector. However, timeseries decomposition analysis shows that (1) four different phases can be distinguished in the evolution of energy intensity of the Basque industry from 1982 to 2001 and (2) that the evolution of the “Iron and Steel” sector is determinant when explaining those phases. Moreover, the analysis stresses the necessity to disaggregate the “Iron and Steel” sector in order to be able to distinguish purely technological effects from the rest of intrasectorial changes.

[ES] El presente trabajo tiene por objeto el estudio del nivel de endeudamiento, el coste de la deuda y las rentabilidades de la industria del calzado de la Comunidad Autónoma de La Rioja por sectores y tamaños. De acuerdo con la Economía Industrial, que considera el sector de actividad como el principal determinante de los resultados de las organizaciones, se analiza si las variables estudiadas son distintas en función de su pertenencia al sector del calzado en comparación con el de la industria agroalimentaria, por ser éste el más importante de la economía de la región. Por otro lado, de acuerdo con la Teoría de los Recursos y Capacidades, que considera que son los factores internos los que explican las diferentes rentabilidades, estudiaremos un recurso interno como es el tamaño, viendo su influencia sobre las variables comentadas. Por último, los resultados del estudio conjunto de la pertenencia a un sector de actividad por tamaños homogéneos nos permiten afirmar que el coste de la deuda de las pequeñas empresas es significativamente distinto en función de dicho sector de pertenencia.

[ES] Este trabajo propone una serie de factores como determinantes del nivel de expansión internacional de la industria vitivinícola chilena: i) tamaño de la empresa; ii) gestión de la calidad; iii) tecnologías de la información y la comunicación; iv) planificación de la gestión internacional, y finalmente, v) adaptación de la estrategia de marketing internacional. El contraste empírico sobre la base de datos de exportación de la industria vitivinícola chilena entre los años 2004 y 2007, permitió confirmar seis de las siete hipótesis planteadas. Este estudio concluye con un apartado destinado a resumir las principales contribuciones teóricas y prácticas, así como las limitaciones y futuras líneas de investigación.

[ES] La necesidad de determinar los requerimientos del cliente y satisfacerlos se ha convertido en el principal objetivo de las empresas. Gestionar esa actividad, comúnmente asociada al departamento de marketing, ha llegado a ser el fin de cualquier sistema de calidad, y por ende, del resto de departamentos de la organización. A través de un estudio de casos, este trabajo pretende identificar cuales son las prácticas de marketing habituales en la industria del mueble, y plantear un marco de actuación idóneo de acuerdo con los procedimientos establecidos en las normas de calidad ISO 9000:2000.

[ES] El sector de la construcción tiene, en España, una notable importancia, por su aportación al PIB (del entorno del 10%) y al empleo (en torno al 10%) y porque aglutina un amplio tejido empresarial. El deterioro de la situación económica y la saturación del mercado residencial han llevado a una fuerte contracción de la actividad constructiva, después una larga época de crecimiento.
