Experiences of spanish public administration in requirements management and acquisition management processes

This paper shows the main contributions of the 1st Symposium on Improvement Process Models and Software Quality of Public Administrations. The obtained results expose the need to promote the implementation of Software Maturity Models and show possible advantages of its application in software processes of Public Administrations. Specifically, it was analyzed the current status in two process areas: Requirements Management and Subcontracting Management.

Dynamic Model-based Management of Service-Oriented Infrastructure.

Models are an effective tool for systems and software design. They allow software architects to abstract from the non-relevant details. Those qualities are also useful for the technical management of networks, systems and software, such as those that compose service oriented architectures. Models can provide a set of well-defined abstractions over the distributed heterogeneous service infrastructure that enable its automated management. We propose to use the managed system as a source of dynamically generated runtime models, and decompose management processes into a composition of model transformations. We have created an autonomic service deployment and configuration architecture that obtains, analyzes, and transforms system models to apply the required actions, while being oblivious to the low-level details. An instrumentation layer automatically builds these models and interprets the planned management actions to the system. We illustrate these concepts with a distributed service update operation.

The impact of sustainable construction and knowledge management on sustainability goals. A review of the venezuelan renewable energy sector

The recognition of the relevance of energy, especially of the renewable energies generated by the sun, water, wind, tides, modern biomass or thermal is growing significantly in the global society based on the possibility it has to improve societies′ quality of life, to support poverty reduction and sustainable development. Renewable energy, and mainly the energy generated by large hydropower generation projects that supply most of the renewable energy consumed by developing countries, requires many technical, legal, financial and social complex processes sustained by innovations and valuable knowledge. Besides these efforts, renewable energy requires a solid infrastructure to generate and distribute the energy resources needed to solve the basic needs of society. This demands a proper construction performance to deliver the energy projects planned according to specifications and respecting environmental and social concerns, which implies the observance of sustainable construction guidelines. But construction projects are complex and demanding and frequently face time and cost overruns that may cause negative impacts on the initial planning and thus on society. The renewable energy issue and the large renewable energy power generation and distribution projects are particularly significant for developing countries and for Latin America in particular, as this region concentrates an important hydropower potential and installed capacity. Using as references the performance of Venezuelan large hydropower generation projects and the Guri dam construction, this research evaluates the tight relationship existing between sustainable construction and knowledge management and their impact to achieve sustainability goals. The knowledge management processes are proposed as a basic strategy to allow learning from successes and failures obtained in previous projects and transform the enhancement opportunites into actions to improve the performance of the renewable energy power generation and distribution projects.

Project Management : Gestión de la remedición mediambiental de las plantas de gas manufacturado

Para hacerse cargo del legado de las Plantas de Gas Manufacturado (MGP) en el Estado de Nueva York, la División de Remediación Medioambiental del Departamento de Conservación Medioambiental, creo las Investigaciones de las áreas afectadas y el Programa de Remediación Medioambiental. Con el paso de los años, la conciencia y entendimiento de la importancia y complejidad de estos proyectos fue creciendo, ya que las investigaciones realizadas daban fe del tamaño y extensión de la contaminación asociada a las plantas de gas manufacturado, propiedad ahora de las diversas compañías de gas que operan a lo largo y ancho del Estado de Nueva York. Tras varios años dentro del Programa de Remediación Medioambiental, muchas de estas compañías han intentado manejar estos vastos y complejos proyectos como han podido, dejándose llevar un poco, subestimando y pasando por alto muchos detalles, ya que al fin y al cabo son proyecto regulados por el estado y que, por tanto, son financiados enteramente por este. Esto ha ido causando en los últimos años grandes problemas a algunas Compañías que a la hora de reportar estos proyectos se han encontrado con una falta total de control y grandes lagunas que resolver. Una técnica para resolver estos problemas es hacer uso de grandes técnicas de gestión empresarial como es el Project Management. En este proyecto se exponen y desarrollan las técnicas que han de utilizarse para integrar la Gestión de Proyectos con el fin de poder gestionar y coordinar las competentes demandas de alcance, tiempo, costes, calidad, recursos, y riesgos con el fin de alcanzar los requerimientos y objetivos del proyecto y de la Compañía. ABSTRACT To address the Manufactured Gas Plant (MGP) legacy in New York State, the Department of Environmental Conservation’s Division of Environmental Remediation has established the MGP Site Investigation and Remediation Programs. With the passage of time the Department’s understanding of the complexity of these sites grew, as investigations identified the extend of the contamination problem associated with many MGPs, property of the Operating Companies in the State. Through many years under the Remediation Programs, some Operating Companies have tried to manage these large and complex projects as they could, underestimating and overlooking them, as they were, in fact, regulated and financed by the Department. This has cause a lot of controlling issues and gaps to solve to the companies. Now the companies are trying to solve this kind of problems using the more innovative management techniques, as Project Management. This project expose and explains how to integrate the project management processes into the MGP Projects under the Remediation Program, to manage and balance the competing demands of scope, time ,cost, quality, resources, and risk to meet the project and company’s requirements and objectives.

Metamodelo para la definición, implantación y mejora de los procesos de gestión de proyectos

En los últimos años hemos sido testigos de la creciente demanda de software para resolver problemas cada vez más complejos y de mayor valor agregado. Bajo estas circunstancias, nos podemos hacer la siguiente pregunta: ¿Está preparada la industria de software para entregar el software que se necesita en los próximos años, de acuerdo con las demandas del cliente? Hoy en día, muchos expertos creen que el éxito de esta industria dependerá de su capacidad para gestionar los proyectos, las personas y los recursos. En este sentido, la gestión de proyectos es un factor clave para el éxito de los proyectos software en todo el mundo. Además, considerando que las Pequeñas y Medianas Empresas de software (PYMEs) representan el 99,87% de las empresas españolas, es vital para este tipo de empresas la implementación de los procesos involucrados con la gestión de proyectos. Es cierto que existen muchos modelos que mejoran la eficacia de la gestión de proyectos, pero la mayoría de ellos se centra únicamente en dos procesos: la planificación del proyecto y la monitorización y control del proyecto, ninguno de los cuales a menudo es asequible para las PYMEs. Estos modelos se basan en el consenso de un grupo de trabajo designado para establecer cómo debe ser gestionado el proceso software. Los modelos son bastante útiles ya que proporcionan lineamientos generales sobre dónde empezar a mejorar la gestión de los proyectos, y en qué orden, a personas que no saben cómo hacerlo. Sin embargo, como se ha dicho anteriormente, la mayoría de estos modelos solamente funcionan en escenarios dentro de las grandes empresas. Por lo tanto, es necesario adaptar los modelos y herramientas para el contexto de PYMEs. Esta tesis doctoral presenta una solución complementaria basada en la aplicación de un metamodelo. Este metamodelo es creado para mejorar la calidad de los procesos de la gestión de proyectos a través de la incorporación de prácticas eficaces identificadas a través del análisis y estudio de los modelos y normas existentes relacionadas con la gestión de proyectos. viii ProMEP – Metamodelo para la gestión de proyectos Por lo tanto, el metamodelo PROMEP (Gestión de Proyectos basada en Prácticas Efectivas) permitirá establecer un proceso estándar de gestión de proyectos que puede adaptarse a los proyectos de cada empresa a través de dos pasos: En primer lugar, para obtener una fotografía instantánea (o base) de los procesos de gestión de proyectos de las PYMEs se creó un cuestionario de dos fases para identificar tanto las prácticas realizadas y como las no realizadas. El cuestionario propuesto se basa en el Modelo de Madurez y Capacidad Integrado para el Desarrollo v1.2 (CMMI-DEV v1.2). Como resultado adicional, se espera que la aplicación de este cuestionario ayude a las PYMEs a identificar aquellas prácticas que se llevan a cabo, pero no son documentadas, aquellas que necesitan más atención, y aquellas que no se realizan debido a la mala gestión o al desconocimiento. En segundo lugar, para apoyar fácilmente y eficazmente las tareas de gestión de proyectos software del metamodelo PROMEP, se diseñó una biblioteca de activos de proceso (PAL) para apoyar la definición de los procesos de gestión de proyectos y realizar una gestión cuantitativa de cada proyecto de las PYMEs. Ambos pasos se han implementado como una herramienta computacional que apoya nuestro enfoque de metamodelo. En concreto, la presente investigación propone la construcción del metamodelo PROMEP para aquellas PYMEs que desarrollan productos software de tal forma que les permita planificar, monitorizar y controlar sus proyectos software, identificar los riesgos y tomar las medidas correctivas necesarias, establecer y mantener un conjunto de activos de proceso, definir un mecanismo cuantitativo para predecir el rendimiento de los procesos, y obtener información de mejora. Por lo tanto, nuestro estudio sugiere un metamodelo alternativo para lograr mayores niveles de rendimiento en los entornos de PYMEs. Así, el objetivo principal de esta tesis es ayudar a reducir los excesos de trabajo y el tiempo de entrega, y aumentar así la calidad del software producido en este tipo de organizaciones. Abstract In recent years we have been witnessing the increasing demand for software to solve more and more complex tasks and greater added value. Under these circumstances, we can ourselves the following question: Is the software industry prepared to deliver the software that is needed in the coming years, according to client demands? Nowadays, many experts believe that the industry’ success will depend on its capacity to manage the projects, people and resources. In this sense, project management is a key factor for software project success around the world. Moreover, taking into account that small and medium-sized software enterprises (SMSe) are the 99.87% of the Spanish enterprises, it is vital for this type of enterprises to implement the processes involved in project management. It is true that there are many models that improve the project management effectiveness, but most of them are focused only on two processes: project planning and project monitoring and control, neither of which is affordable for SMSe. Such models are based on the consensus of a designated working group on how software process should be managed. They are very useful in that they provide general guidelines on where to start improving the project management, and in which order, to people who do not know how to do it. However, as we said, the majority of these models have only worked in scenarios within large companies. So, it is necessary to adapt these models and tools to the context of SMSe. A complementary solution based on the implementation of a metamodel is presented in this thesis. This metamodel is created to improve the quality of project management processes through the incorporation of effective practices identified through the analysis and study of relevant models and standards related to project management. Thus, the PROMEP (PROject Management based on Effective Practices) metamodel will allow establishing a project management standard process to be tailored to each enterprise’s project through two steps: Firstly, to obtain a baseline snapshot of project management processes in SMSe a two-phase questionnaire was created to identify both performed and nonperformed practices. The x ProMEP – Metamodelo para la gestión de proyectos proposed questionnaire is based on Capability Maturity Model Integration for Development v1.2. As additional result, it is expected that the application of the questionnaire to the processes will help SMSe to identify those practices which are performed but not documented, which practices need more attention, and which are not implemented due to bad management or unawareness. Secondly, to easily an effectively support the software project management tasks in the PROMEP metamodel, a Process Asset Library (PAL) is designed to support the definition of project management processes and to achieve quantitative project management in SMSe. Both steps have been implemented as a computational tool that supports our metamodel approach. Concretely, the present research proposes the accomplishment of the PROMEP metamodel for those SMSe which develop software products and enable them to plan, supervise and control their software projects, identify risks and take corrective actions, establish and maintain a set of process assets, define quantitative models that predict the process performance, and provide improvement information. So, our study suggests an alternative metamodel to achieve higher performance levels in the SMSe environments. The main objective of this thesis is help to reduce software overruns and delivery time, and increase software quality in these types of organizations.

Desarrollo de un sistema de gestión de tutorías a través de una aplicación móvil

RESUMEN Con la irrupción y el auge de las tecnologías móviles en estos últimos años, se ha hecho patente que los procesos de gestión tienden a ser controlados a través de estas tecnologías, permitiendo al usuario centralizar todos los servicios que le sea posible en un dispositivo de uso tan común como el teléfono móvil, así como acceder a ellos de forma rápida y cómoda. El sistema de tutorías de la Universidad Politécnica de Madrid no es la excepción. Desde su creación, el Grupo de Innovación Educativa Tutorial Action (GIETA) [1] ha trabajado en la modernización del proceso de gestión que conlleva el sistema de tutorías, buscando las deficiencias del sistema tradicional que pudiesen resolverse utilizando la tecnología. Este Trabajo de Fin de Grado (TFG) ha tenido como objetivo apoyar la labor iniciada por el GIETA, desarrollando un sistema de gestión de tutorías mediante una aplicación móvil. Para lograr este objetivo, inicialmente se realizó un proceso de reflexión sobre, entre otras cuestiones, la razón de ser de la aplicación a desarrollar, las ventajas que aportaría al usuario final, aquellos riesgos que podían amenazar al proyecto, etc. Este proceso se englobó dentro de la herramienta Agile Inception Deck. Tras este proceso de reflexión, se estructuró el proyecto en fases o sprints de desarrollo, en las que se llevó a cabo la implementación del resultado final de este TFG, una aplicación móvil para el sistema operativo Android, que aporta funcionalidad que resuelve todos los requisitos asociados a las distintas historias de usuario definidas para el proyecto. ABSTRACT With the rise of mobile technologies in recent years, it has become clear that management processes tend to be controlled through these technologies, allowing users to centralize all services as possible, using a device as common as the mobile phone, and access them quickly and easily. The tutorial system at the Technical University of Madrid is not an exception. Since it’s creation, the Group of Educational Innovation Tutorial Action has worked on the modernization of the management process that involves the tutorial system, looking for weaknesses of the traditional system that could be solved using technology. This TFG has aimed to support the work initiated by the GIETA, developing a tutorship management system through a mobile application. To achieve this goal, initially a process of reflection was held about, inter alia, the rationale for the application to be developed, the advantages it would bring to the final user, the risks that could threaten the project, etc. This process is encompassed within the Agile Inception Deck tool. After this process of reflection, the project was divided into phases or sprints, in which took place the implementation of the outcome of the TFG, a mobile application for the Android operating system, which provides functionality that meets all the requirements associated with the different user stories defined for the project.

La casa crecedera. El crecimiento programado de la vivienda con innovación europea y economía de medios latinoamericana

El concepto de casa crecedera, tal y como lo conocemos en la actualidad, se acuñó por primera vez en 1932 en el concurso Das Wachsende Haus organizado por Martin Wagner y Hans Poelzig dentro del marco de la Exposición Internacional Sonne, Luft und Haus für alle, promovida por la Oficina de Turismo de la ciudad de Berlín. En dicho concurso, se definía este tipo de vivienda como aquella célula básica o vivienda semilla que, dependiendo de las necesidades y posibilidades de los habitantes, podía crecer mediante otras estancias, conformando una vivienda completa en sí misma en cada fase de crecimiento. Numerosos arquitectos de primer orden, tales como Walter Gropius, Bruno Taut, Erich Mendelsohn o Hans Scharoun, participaron en este concurso, abriendo una nueva vía de exploración dentro de la vivienda flexible, la del crecimiento programado. A partir de ese momento, en Europa, y subsecuentemente en EEUU y otras regiones desarrolladas, se iniciaron numerosas investigaciones teóricas y prácticas en torno al fenómeno del crecimiento en la vivienda desde un enfoque vinculado a la innovación, tanto espacial como técnica. Por otro lado, aunque dentro del marco de la arquitectura popular de otros países, ya se ensayaban viviendas crecederas desde el siglo XVIII debido a que, por su tamaño, eran más asequibles dentro del mercado. Desde los años treinta, numerosos países en vías de desarrollo tuvieron que lidiar con migraciones masivas del campo a la ciudad, por lo que se construyeron grandes conjuntos habitacionales que, en numerosos casos, estaban conformados por viviendas crecederas. En todos ellos, la aproximación al crecimiento de la vivienda se daba desde una perspectiva diferente a la de los países desarrollados. Se primaba la economía de medios, el uso de sistemas constructivos de bajo costo y, en muchos casos, se fomentaba incluso la autoconstrucción guiada, frente a las construcciones prefabricadas ensambladas por técnicos especializados que se proponían, por ejemplo, en los casos europeos. Para realizar esta investigación, se recopiló información de estas y otras viviendas. A continuación, se identificaron distintas maneras de producir el crecimiento, atendiendo a su posición relativa respecto de la vivienda semilla, a las que se denominó mecanismos de ampliación, utilizados indistintamente sin tener en cuenta la ubicación geográfica de cada casa. La cuestión de porqué se prefiere un mecanismo en lugar de otro en un caso determinado, desencadenó el principal objetivo de esta Tesis: la elaboración de un sistema de análisis y diagnóstico de la vivienda crecedera que, de acuerdo a determinados parámetros, permitiera indicar cuál es la ampliación o sucesión de ampliaciones óptimas para una familia concreta, en una ubicación establecida. Se partió de la idea de que el crecimiento de la vivienda está estrechamente ligado a la evolución de la unidad de convivencia que reside en ella, de manera que la casa se transformó en un hábitat dinámico. Además se atendió a la complejidad y variabilidad del fenómeno, sujeto a numerosos factores socio-económicos difícilmente previsibles en el tiempo, pero fácilmente monitorizables según unos patrones determinados vinculados a la normatividad, el número de habitantes, el ahorro medio, etc. Como consecuencia, para el diseño del sistema de optimización de la vivienda crecedera, se utilizaron patrones evolutivos. Dichos patrones, alejados ya del concepto espacial y morfológico usualmente utilizado en arquitectura por figuras como C. Alexander o J. Habraken, pasaron a entenderse como una secuencia de eventos en el tiempo (espaciales, sociales, económicos, legales, etc.), que describen el proceso de transformación y que son peculiares de cada vivienda. De esta manera, el tiempo adquirió una especial importancia al convertirse en otro material más del proyecto arquitectónico. Fue en la construcción de los patrones donde se identificaron los mencionados mecanismos de ampliación, entendidos también como sistemas de compactación de la ciudad a través de la ocupación tridimensional del espacio. Al estudiar la densidad, mediante los conceptos de holgura y hacinamiento, se aceptó la congestión de las ciudades como un valor positivo. De esta forma, las posibles transformaciones realizadas por los habitantes (previstas desde un inicio) sobre el escenario del habitar (vivienda semilla), se convirtieron también en herramientas de proyecto urbano que responden a condicionantes del lugar y de los habitantes con distintas intensidades de crecimiento, ocupación y densidad. Igualmente, en el proceso de diseño del sistema de optimización, se detectaron las estrategias para la adaptabilidad y transformación de la casa crecedera, es decir, aquella serie de acciones encaminadas a la alteración de la vivienda para facilitar su ampliación, y que engloban desde sistemas constructivos en espera, que facilitan las costuras entre crecimiento y vivienda semilla, hasta sistemas espaciales que permiten que la casa altere su uso transformándose en un hábitat productivo o en un artefacto de renta. Así como los mecanismos de ampliación están asociados a la morfología, se descubrió que su uso es independiente de la localización, y que las estrategias de adaptabilidad de la vivienda se encuentran ligadas a sistemas constructivos o procesos de gestión vinculados a una región concreta. De esta manera, la combinación de los mecanismos con las estrategias caracterizan el proceso de evolución de la vivienda, vinculándola a unos determinados condicionantes sociales, geográficos y por tanto, constructivos. Finalmente, a través de la adecuada combinación de mecanismos de ampliación y estrategias de adaptabilidad en el proyecto de la vivienda con crecimiento programado es posible optimizar su desarrollo en términos económicos, constructivos, sociales y espaciales. Como resultado, esto ayudaría no sólo a mejorar la vida de los habitantes de la vivienda semilla en términos cualitativos y cuantitativos, sino también a compactar las ciudades mediante sistemas incluyentes, ya que las casas crecederas proporcionan una mayor complejidad de usos y diversidad de relaciones sociales. ABSTRACT The growing house concept -as we currently know it- was used for the first time back in 1932 in the competition Das Wachsende Haus organized by Martin Wagner and Hans Poelzig during the International Exhibition Sonne, Luft und Haus für alle, promoted by Berlin's Tourist Office. In that competition this type of housing was defined as a basic cell or a seed house unit, and depending on the needs and capabilities of the residents it could grow by adding rooms and defining itself as a complete house unit during each growing stage. Many world-top class architects such as Walter Gropius, Bruno Taut, Erich Mendelsohn or Hans Scharoun, were part of this competition exploring a new path in the flexible housing field, the scheduled grownth. From that moment and on, in Europe -and subsequently in the USA and other developed areas- many theorical and pragmatical researchs were directed towards the growing house phenomena, coming from an initial approach related to innovation, spacial and technical innovation. Furthermore -inside the traditional architecture frame in other countries, growing houses were already tested in the XVIII century- mainly due to the size were more affordable in the Real State Market. Since the 30's decade many developing countries had to deal with massive migration movements from the countryside to cities, building large housing developments were -in many cases- formed by growing housing units. In all of these developing countries the growing house approach was drawn from a different perspective than in the developed countries. An economy of means was prioritized, the utilization of low cost construction systems and -in many cases- a guided self-construction was prioritized versus the prefabricated constructions set by specialized technics that were proposed -for instance- in the European cases. To proceed with this research, information from these -and other- housing units was gathered. From then and on different ways to perform the growing actions were identified, according to its relative position from the seed house unit, these ways were named as addition or enlargement mechanisms indifferently utilized without adknowledging the geographic location for each house. The question of why one addition mechanism is preferred over another in any given case became the main target of this Thesis; the ellaboration of an analysis and diagnosis system for the growing house -according to certain parameters- would allow to point out which is the addition or addition process more efficient for a certain family in a particular location. As a starting point the grownth of the housing unit is directly linked to the evolution of the family unit that lives on it, so the house becomes a dynamic habitat. The complexity and the variability of the phenomena was taken into consideration related to a great number of socio-economic factors hardly able to be foreseen ahead on time but easy to be monitored according to certain patterns linked to regulation, population, average savings, etc As a consequence, to design the optimization system for the growing house, evolutionary patterns were utilized. Those patterns far away from the spatial and morphologic concept normally utilized in Architecture by characters like C. Alexander or J. Habraken, started to be understood like a sequence of events on time (spatial events, social events, economic events, legal events, etc) that describes the transformation process and that are particular for each housing unit. Therefore time became something important as another ingredient in the Architectural Project. The before mentioned addition or enlargement mechanisms were identified while building the patterns; these mechanisms were also understood as city's system of compactation through the tridimendional ocupation of space. Studying density, thorough the concepts of comfort and overcrowding, traffic congestion in the city was accepted as a positive value. This way, the possible transformations made by the residents (planned from the begining) about the residencial scenary (seed house), also became tools of the urban project that are a response to site's distinctive features and to the residents with different grownth intensities, activities and density Likewise, during the process of designing the optimization system, strategies for adaptations and transformation of the growing house were detected, in other words, the serial chain of actions directed to modify the house easing its enlargement or addition, and that comprehends from constructive systems on hold -that smooths the costures between grownth and housing seed- to spatial systems that allows that the house modify its utilization, becoming a productive habitat or a rental asset. Because the enlargement mechanisms are linked to the morphology, it was discovered that the use it's not related to the location, and that the adaptation strategies of the houses are linked to constructive systems or management processes linked to a particular area. This way the combination of mechanisms and strategies characterizes the process of housing evolution, linking it to certain social and geographic peculiarities and therefore constructives. At last, through the certain combination of enlargement mechanisms and adaptability strategies in the housing with scheduled grownth project is possible to optimize its development in economic, constructive, social and spatial terms. As a result, this would help not only to improve the life of the seed house residents in qualitative and quantitative terms but also to compact the cities through inclusive systems, given that the growing houses provide a larger complexity of uses and social relations.

Sistemas urbanos emergentes: procesos informales de gestión y producción de espacio público

Esta investigación analiza la capacidad del urbanismo de albergar sistemas emergentes de gestión urbana. El objetivo de esta tesis es describir estos procedimientos informales, realizando un exhaustivo recorrido a través de diversas experiencias de alteración del modo de gestión urbana al uso, para dar lugar a una sistematización de estos procesos que siente las bases para plantear nuevas formas de gestión urbana. Es decir, el fin no es tanto hacer una clasificación de las intervenciones más relevantes en materia urbana, sino descubrir su estructura, un orden para el desorden, una taxonomía en esas actuaciones que permita reformular las formas actuales de gestión de lo público. Se ha tratado de dibujar un mapa de oportunidades posibles en torno a la gestión del espacio urbano. A través de los procesos estudiados, esta investigación analiza los éxitos y fracasos obtenidos en los últimos cinco años de gestión alternativa de espacios vacantes, buscando extraer formulas susceptibles de incorporarse al modo actual de hacer ciudad. Este estudio pretende abordar un aspecto parcial, aunque fundamental del urbanismo, dando prioridad a lo público, sin la intención de negar el resto de formas del espacio urbano. Se concentra en los parámetros relativos a la interpretación de lo público: desatiende al conjunto urbano para descifrar ese fragmento. Así, el interés principal de esta tesis se concentra en la producción del espacio público. Al entender este ámbito como no exclusivo del urbanismo, otras actividades como el arte, la filosofía, la antropología o la sociología han aportado aspectos fundamentales dentro de esta investigación. De esta forma se ofrece un acercamiento poliédrico desde puntos de vista interdisciplinares, tratando de descubrir con rigor las posibilidades contrastadas de mejora del espacio urbano producido por los procesos emergentes de gestión informal de lo público. Mediante un metodología creada ex profeso (una estructura definida por tres líneas estratégicas: Gobernanza, Complejidad y Cohesión Social, que se desglosan en seis conceptos clave cada una) esta investigación analiza los aspectos relativos a la producción informal del espacio público de los sistemas emergentes. En relación con la Gobernanza, una parte de esta tesis se dedica al estudio de la informalidad, la transversalidad, la apropiación, la participación, la transparencia y las redes. La Complejidad se ha estudiado en su relación con la diversidad urbana, el uso sostenible del espacio público, la reactivación, la producción de espacio público, la ecología urbana y los procesos creativos. Para Cohesión Social se ha investigado la innovación en equipamientos, los procesos bottom-up, el rizoma, la identidad, los sistemas líquidos y el empoderamiento. Esta máquina para analizar se prueba en tres soportes urbanos: la escena urbana, los edificios-contenedores y los vacíos urbanos. Se han estudiado cinco situaciones urbanas en la ciudad de Madrid, seleccionados por ser las prácticas urbanas más relevantes de los últimos cinco años. Si bien este análisis nace de estos cincos casos, el modelo podría ser útil para otras investigaciones interesadas en los aspectos informales de la gestión urbana. Esta investigación se propone reclamar otras dimensiones más innovadoras que, si bien se escapan a los modos habituales de trabajar del urbanista, se revelan intensamente en los modos actuales de reclamar y producir espacio urbano. Se ha pretendido descubrir el espacio urbano como contenedor situacional del sentido público, potencial multiplicador de efectos funcionales como la gestión, la temporalidad, la participación, la rehabilitación, la multiplicidad de usos, la corrección del compacidad; efectos perceptuales y estéticos en la escena urbana; efectos políticos, de formación, de adquisición de poder; efectos sociales como la generación de nuevas redes, la creación de identidades. Se pretende que esta investigación arroje conclusiones que puedan tener aplicabilidad en la gestión y planificación del espacio público de ciudades y entornos urbanos inmersos a procesos semejantes. ABSTRACT This research examines the ability of urban planning to accommodate emerging urban management systems. The purpose of this thesis is to describe such informal procedures, by carrying out an exhaustive review across the different approaches to urban management, in order to systematize them as the basis for new ways of urban management. The aim is not, that is, to classify relevant urban interventions, but to recognize the intrinsic structure, an order for disorder, a taxonomy in those proceedings that could help reformulating existing forms of public management. The attempt has been to draw a map of possible opportunities around the management of urban space. Through the processes that have been the object of study, this research analyzes the successes and failures over the last five years of alternative management of vacant spaces, seeking to extract formulas that are likely to join the current way of making city. The focus of this urban study is the interpretation of public concepts, considered as key dimensions, not obliterating the other forms of urban space, but trying to make an in-depth analysis of this fragment within the global urban concept. Other activities intrinsically associated to public space generation, such as art, philosophy, anthropology or even sociology, are also contributing to this research. This interdisciplinary approach tries to enrich the research by recognizing the informal elements participating in emergent public management processes. The ex profeso devised methodology is structured by three main strategies: governance, complexity and Social Cohesiveness. Governance considers elements associated to informality, transversal dynamics, appropriation, participation, transparency and networking. Complexity encompasses elements of urban diversity, sustainable usage of public space, reactivation, urban space production, urban ecology and creative processes. Social Cohesiveness includes elements for equipment innovation, bottom-up processes, rhizome, identity, liquid systems and empowerment. This analyzing machine is tested on three urban scenarios: the urban scene, container buildings and empty spaces. Five relevant urban situations in Madrid have been selected, all of them developed in last five years, thus establishing the basis for other experiences of informal urban management. The result of the research, confirms the relevance of additional dimensions to traditional approaches for urban development. The urban space is recognized as a situational container of public sense and a potential multiplier of functional effects such as public management, temporality, participation, rehabilitation, multiplicity of uses, correction of compactness; perceptual and esthetic effects on the urban scene; politic effects, training, empowerment; social effects as generating new networks and identity creation. To sum up, the purpose of this thesis is to share the conclusions obtained by evaluating reference scenarios that could be applied in similar processes for cities and urban environment management and planning.

Commonalities between networking in multiplayer computer games and negotiation processes in a future multi-layered Air Traffic Management (ATM) system

First, this paper describes a future layered Air Traffic Management (ATM) system centred in the execution phase of flights. The layered ATM model is based on the work currently performed by SESAR [1] and takes into account the availability of accurate and updated flight information ?seen by all? across the European airspace. This shared information of each flight will be referred as Reference Business Trajectory (RBT). In the layered ATM system, exchanges of information will involve several actors (human or automatic), which will have varying time horizons, areas of responsibility and tasks. Second, the paper will identify the need to define the negotiation processes required to agree revisions to the RBT in the layered ATM system. Third, the final objective of the paper is to bring to the attention of researchers and engineers the communalities between multi-player games and Collaborative Decision Making processes (CDM) in a layered ATM system

Analysing the complexity of the model-based decision making processes within the industrial management context

PURPOSE The decision-making process plays a key role in organizations. Every decision-making process produces a final choice that may or may not prompt action. Recurrently, decision makers find themselves in the dichotomous question of following a traditional sequence decision-making process where the output of a decision is used as the input of the next stage of the decision, or following a joint decision-making approach where several decisions are taken simultaneously. The implication of the decision-making process will impact different players of the organization. The choice of the decision- making approach becomes difficult to find, even with the current literature and practitioners’ knowledge. The pursuit of better ways for making decisions has been a common goal for academics and practitioners. Management scientists use different techniques and approaches to improve different types of decisions. The purpose of this decision is to use the available resources as well as possible (data and techniques) to achieve the objectives of the organization. The developing and applying of models and concepts may be helpful to solve managerial problems faced every day in different companies. As a result of this research different decision models are presented to contribute to the body of knowledge of management science. The first models are focused on the manufacturing industry and the second part of the models on the health care industry. Despite these models being case specific, they serve the purpose of exemplifying that different approaches to the problems and could provide interesting results. Unfortunately, there is no universal recipe that could be applied to all the problems. Furthermore, the same model could deliver good results with certain data and bad results for other data. A framework to analyse the data before selecting the model to be used is presented and tested in the models developed to exemplify the ideas. METHODOLOGY As the first step of the research a systematic literature review on the joint decision is presented, as are the different opinions and suggestions of different scholars. For the next stage of the thesis, the decision-making process of more than 50 companies was analysed in companies from different sectors in the production planning area at the Job Shop level. The data was obtained using surveys and face-to-face interviews. The following part of the research into the decision-making process was held in two application fields that are highly relevant for our society; manufacturing and health care. The first step was to study the interactions and develop a mathematical model for the replenishment of the car assembly where the problem of “Vehicle routing problem and Inventory” were combined. The next step was to add the scheduling or car production (car sequencing) decision and use some metaheuristics such as ant colony and genetic algorithms to measure if the behaviour is kept up with different case size problems. A similar approach is presented in a production of semiconductors and aviation parts, where a hoist has to change from one station to another to deal with the work, and a jobs schedule has to be done. However, for this problem simulation was used for experimentation. In parallel, the scheduling of operating rooms was studied. Surgeries were allocated to surgeons and the scheduling of operating rooms was analysed. The first part of the research was done in a Teaching hospital, and for the second part the interaction of uncertainty was added. Once the previous problem had been analysed a general framework to characterize the instance was built. In the final chapter a general conclusion is presented. FINDINGS AND PRACTICAL IMPLICATIONS The first part of the contributions is an update of the decision-making literature review. Also an analysis of the possible savings resulting from a change in the decision process is made. Then, the results of the survey, which present a lack of consistency between what the managers believe and the reality of the integration of their decisions. In the next stage of the thesis, a contribution to the body of knowledge of the operation research, with the joint solution of the replenishment, sequencing and inventory problem in the assembly line is made, together with a parallel work with the operating rooms scheduling where different solutions approaches are presented. In addition to the contribution of the solving methods, with the use of different techniques, the main contribution is the framework that is proposed to pre-evaluate the problem before thinking of the techniques to solve it. However, there is no straightforward answer as to whether it is better to have joint or sequential solutions. Following the proposed framework with the evaluation of factors such as the flexibility of the answer, the number of actors, and the tightness of the data, give us important hints as to the most suitable direction to take to tackle the problem. RESEARCH LIMITATIONS AND AVENUES FOR FUTURE RESEARCH In the first part of the work it was really complicated to calculate the possible savings of different projects, since in many papers these quantities are not reported or the impact is based on non-quantifiable benefits. The other issue is the confidentiality of many projects where the data cannot be presented. For the car assembly line problem more computational power would allow us to solve bigger instances. For the operation research problem there was a lack of historical data to perform a parallel analysis in the teaching hospital. In order to keep testing the decision framework it is necessary to keep applying more case studies in order to generalize the results and make them more evident and less ambiguous. The health care field offers great opportunities since despite the recent awareness of the need to improve the decision-making process there are many opportunities to improve. Another big difference with the automotive industry is that the last improvements are not spread among all the actors. Therefore, in the future this research will focus more on the collaboration between academia and the health care sector.
