D., Christine Henze Redaktionsschluß: 31.12.2004 Institut für Informatik 3 Vorwort Die Informatik ist weiterhin dabei, die Gesellschaft in vielen Bereichen zu beeinflussen und zu verändern. Die schnelle Entwicklung stellt das Institut für Informatik ständig vor die Herausforderung, diesem Wandel in Lehre und Forschung gerecht zu werden. Kontinu- ierliche Aktualisierung von Lehrinhalten sowie die Entwicklung neuer Forschungsideen werden auch weiterhin die Grundlage erfolgreicher Arbeit des Instituts sein. Auch im Jahre 2004 gelang es dem Institut, seine Professorenschaft zu erweitern. Prof. J. Redlich nahm zum 1. Juli 2004 den Ruf auf die Professur Systemarchitektur an. Seine Professur deckt die Bereiche Betriebssysteme und Kommunikation hervorragend ab. Als weiterer Kollege wurde im August Prof. R. Reulke auf eine Sonderprofessur berufen; er nahm gleichzeitig seine Arbeit als Abteilungsleiter am benachbarten Institut für Verkehrs- forschung des Deutschen Zentrums für Luft- und Raumfahrt (DLR) auf. Auch in diesem Jahr hat das Institut in Lehre und Forschung Bemerkenswertes geleistet. Besonders hervorzuheben sind die Erfolge der Lehr- und Forschungseinheit Künstliche Intelligenz, die als Teil des GermanTeams beim RoboCup 2004 in Portugal Weltmeister in der „Sony four-legged Robot League“ wurde und die „Open Challenge“ für sich entscheiden konnte. Das Aibo-Team „Humboldt“ unter der Leitung von Prof. Burkhard gewann die GermanOpen in Paderborn in der Liga der vierbeinigen Roboter. Die drei Schwerpunkte des Institutes – Große Datenräume in Web-basierten Umgebungen, Algorithmen und Logik und Modellbasierte Systementwicklung haben weiter an Profil und an Leistungskraft gewonnen. Mit seinen Ringvorlesungen "Schwerpunkte der Informatik" im Wintersemester 2003/2004 zum Thema Eingebettete Systeme , im Sommersemester 2004 zum Thema Modellbasierte Softwareentwicklung und im Wintersemester 2004/2005 zum Thema Große Datenräume in Web-basierten Umgebungen hat das Institut sein Engagement für den Technologie-Standort Adlershof – zusammen mit weiteren Aktivitäten – deutlich gestärkt. Trotz aller Erfolge steht das Jahr 2004 auch für entscheidende Einschnitte, die dem Institut auferlegt wurden. Erst die kommenden fünf Jahre werden die Konsequenzen dieser Einsparungen in Lehre und Forschung deutlich machen. Das Institut wird alles daran setzen, durch geeignete Maßnahmen (erhöhtes Engagement in der Drittmitteleinwerbung, inten- sivere Industriekooperationen, verbesserte Lehre) den negativen Effekten dieser Einspa- rungen entgegenzuwirken. Nur wenn dies gelingt, wird das Institut weiterhin seine Qualität und seine Reputation ausbauen können. In der Lehre wurden die ersten Schritte zur Einführung von Master- und Bachelor- Studiengängen gemacht. Seit dem Wintersemester 2004 ist das Institut zusammen mit der Wirtschaftswissenschaftlichen Fakultät Träger des Master-Studiengangs „Wirtschafts- informatik“, des ersten Studienganges dieser Art in Berlin. Prof. Johann-Christoph Freytag, Ph.D. Geschäftsführender Direktor Berlin, Januar 2005 4 Jahresbericht 2004 Preface Computer Science continues to impact and to change all aspects of our lives. This fast development continuously challenges the Institut für Informatik (Computer Science Department) to adapt its teaching and research. Constant adaptation and keeping research and teaching in-line with these new developments is necessary to guarantee a successful basis for our work at the department. In 2004 the department succeeded to increase again the number of professors. In July Prof. J. Redlich accepted a position in joining the department as the professor for system architecture (German: Systemarchitektur ). His work covers the areas of operating systems and communication. Furthermore, Prof. R. Reulke accepted a “special” professorship (German: Sonderprofessur) in the area of computer vision in August of 2004; at the same time he began his work as the head of one of the departments at the neighboring Institute for Traffic Research (German: Institut für Verkehrsforschung) of the German Center for Aeronautics (Deutschen Zentrum für Luft- und Raumfahrt - DLR). In 2004 the department continuously improved its performance in many aspects showing very good results. In particular, the success of the members of the AI-professorship (Lehr- und Forschungseinheit Künstliche Intelligenz) is worthwhile to mention: At the RoboCup 2004 in Portugal they won as part of the GermanTeam the World Championship in the „Sony four-legged Robot League“; the same is true for the „Open Challenge“ category . The Aibo-Team „Humboldt” lead by Prof. Burkhard won the GermanOpen in Paderborn in the “four-legged Robot League”. The three focal points in research – Large Data Spaces in Web-based Environments , Algorithms and Logic, and Model-driven Software Development – continued to strengthen the department’s capabilities. To strengthen these efforts the department introduced a lecture series (German: Ringvorlesungen) on „Special Topics in Computer Science“ run every semester. During the winter semester 2003/2004 the focus was on Embedded Systems . During the summer semester 2004 the lectures focused on Model-based Software Development. Finally, during the winter semester 2004/2005 the lectures emphasized Large Data Spaces in Web-based Environments . In addition, these lectures helped – in combination with other activities - to increase the visibility of the department within the Technology Park „Adlershof”. Despite all of these achievements, the department also has faced radical reductions during this year which it was forced to accept. The coming five years will show the serious impact of financial and personnel reductions in research and teaching. The department is committed to do everything in compensating the negative impacts these reductions have, by appropriate actions (for example, increased efforts in securing third-party funding, more cooperation with industrial partners, improved teaching quality). Only if the department succeeds in implementing these kinds of measurements, it will be positioned for improving its quality in research and teaching. With respect to the curriculum the department took first steps in introducing Master and Bachelor degrees. Since the winter semester 2004 the Computer Science Department started – together with the Business School (German: Wirtschaftswissenschaftliche Fakultät) – Institut für Informatik 5 a program for a Master degree in Business & Computer Science (German: „Wirtschafts- informatik“) the first one of its kind in Berlin.

While the firm’s sales growth met shareholder expectations, net income remained largely stable. During the following weeks and months, Siemens’ top management not only faced increased pressure from its shareholders, but also higher environmental uncertainty and stronger global competition than during the early and mid-1990s. The challenge for the top management team was to optimize the business portfolio in a way that promised to add substantial shareholder value over the next years.

    2011 Estudio del Departamento de Servicios de Siemens S.A. Autor: Borja Calatayud Soriano Director: Bernardo Tormos Martínez 22/06/2011 1 Borja Calatayud Soriano Prefacio Este es un Trabajo para la Universidad Politécnica de Valencia de final del Máster en la Ingeniería del Mantenimiento, cursado después de haber obtenido la diplomatura de Ingeniero Técnico Industrial Especializado en Mecánica. Se ha realizado el periodo de prácticas en la empresa SIEMENS S.A. la cual y teniendo en cuenta la situación económica actual, se plantea diversas estrategias administrativas, entre ellas centralizar el departamento de organización y gestión del servicio técnico, de la parte de industrias, para toda España. Con estas premisas se decidió realizar este estudio para proponer mejoras en la misma, en el sector de servicio técnico y mantenimiento, estudiando su eficiencia. Pudiendo demostrar así, los conocimientos sobre todo a nivel organizativo adquiridos a lo largo de la formación del máster. Teniendo en cuenta que la empresa ya dispone de sistema organizativo altamente eficiente, sería importante aclarar hasta qué punto se puede mejorar o no la eficicácia del departamento, para que la dirección pueda tener un punto de vista enfocado hacia la correcta gestión del mantenimiento, que no es más que encontrar el equilibrio entre el correcto control y funcionamiento de las instalaciones y el coste del mantenimiento. 2 Borja Calatayud Soriano 1.Índice Prefacio ............................................................................................................................
