Optimizing PV use through active demand side management

With recent technological developments within the field of power conditioning and the progressive decrease of incentives for PV electricity in grid-connected markets, new operation modes for PV systems should be explored beyond the traditional maximization of PV electri city feed-in. An example can be found in the domestic sector, where the use of modern PV hybrid systems combin ed with efficient electrical appliances and demand side management strategies can significantly enhance the PV value for the user. This paper presents an active demand side management system able to displace the consumer’s load curve in response to local (PV hybrid system, user) and external conditions (external grid). In this way, th e consumer becomes an “active consumer” that can also cooperate with others and the grid, increasing even more the PV value for the electrical system.

Sistemas de gestión de puentes : optimización de estrategias de mantenimiento : implementación en redes locales de carreteras

En la actualidad, y en consonancia con la tendencia de “sostenibilidad” extendida a todos los campos y parcelas de la ciencia, nos encontramos con un área de estudio basado en la problemática del inevitable deterioro de las estructuras existentes, y la gestión de las acciones a realizar para mantener las condiciones de servicio de los puentes y prolongar su vida útil. Tal y como se comienza a ver en las inversiones en los países avanzados, con una larga tradición en el desarrollo de sus infraestructuras, se muestra claramente el nuevo marco al que nos dirigimos. Las nuevas tendencias van encaminadas cada vez más a la conservación y mantenimiento, reduciéndose las partidas presupuestarias destinadas a nuevas actuaciones, debido a la completa vertebración territorial que se ha ido instaurando en estos países, entre los que España se encuentra. Este nutrido patrimonio de infraestructuras viarias, que cuentan a su vez con un importante número de estructuras, hacen necesarias las labores de gestión y mantenimiento de los puentes integrantes en las mismas. Bajo estas premisas, la tesis aborda el estado de desarrollo de la implementación de los sistemas de gestión de puentes, las tendencias actuales e identificación de campos por desarrollar, así como la aplicación específica a redes de carreteras de escasos recursos, más allá de la Red Estatal. Además de analizar las diversas metodologías de formación de inventarios, realización de inspecciones y evaluación del estado de puentes, se ha enfocado, como principal objetivo, el desarrollo de un sistema específico de predicción del deterioro y ayuda a la toma de decisiones. Este sistema, adicionalmente a la configuración tradicional de criterios de formación de bases de datos de estructuras e inspecciones, plantea, de forma justificada, la clasificación relativa al conjunto de la red gestionada, según su estado de condición. Eso permite, mediante técnicas de optimización, la correcta toma de decisiones a los técnicos encargados de la gestión de la red. Dentro de los diversos métodos de evaluación de la predicción de evolución del deterioro de cada puente, se plantea la utilización de un método bilineal simplificado envolvente del ajuste empírico realizado y de los modelos markovianos como la solución más efectiva para abordar el análisis de la predicción de la propagación del daño. Todo ello explotando la campaña experimenta realizada que, a partir de una serie de “fotografías técnicas” del estado de la red de puentes gestionados obtenidas mediante las inspecciones realizadas, es capaz de mejorar el proceso habitual de toma de decisiones. Toda la base teórica reflejada en el documento, se ve complementada mediante la implementación de un Sistema de Gestión de Puentes (SGP) específico, adaptado según las necesidades y limitaciones de la administración a la que se ha aplicado, en concreto, la Dirección General de Carreteras de la Junta de Comunidades de Castilla-La Mancha, para una muestra representativa del conjunto de puentes de la red de la provincia de Albacete, partiendo de una situación en la que no existe, actualmente, un sistema formal de gestión de puentes. Tras un meditado análisis del estado del arte dentro de los Capítulos 2 y 3, se plantea un modelo de predicción del deterioro dentro del Capítulo 4 “Modelo de Predicción del Deterioro”. De la misma manera, para la resolución del problema de optimización, se justifica la utilización de un novedoso sistema de optimización secuencial elegido dentro del Capítulo 5, los “Algoritmos Evolutivos”, en sus diferentes variantes, como la herramienta matemática más correcta para distribuir adecuadamente los recursos económicos dedicados a mantenimiento y conservación de los que esta administración pueda disponer en sus partidas de presupuesto a medio plazo. En el Capítulo 6, y en diversos Anexos al presente documento, se muestran los datos y resultados obtenidos de la aplicación específica desarrollada para la red local analizada, utilizando el modelo de deterioro y optimización secuencial, que garantiza la correcta asignación de los escasos recursos de los que disponen las redes autonómicas en España. Se plantea con especial interés la implantación de estos sistemas en la red secundaria española, debido a que reciben en los últimos tiempos una mayor responsabilidad de gestión, con recursos cada vez más limitados. Finalmente, en el Capítulo 7, se plantean una serie de conclusiones que nos hacen reflexionar de la necesidad de comenzar a pasar, en materia de gestión de infraestructuras, de los estudios teóricos y los congresos, hacia la aplicación y la práctica, con un planteamiento que nos debe llevar a cambios importantes en la forma de concebir la labor del ingeniero y las enseñanzas que se imparten en las escuelas. También se enumeran las aportaciones originales que plantea el documento frente al actual estado del arte. Se plantean, de la misma manera, las líneas de investigación en materia de Sistemas de Gestión de Puentes que pueden ayudar a refinar y mejorar los actuales sistemas utilizados. In line with the development of "sustainability" extended to all fields of science, we are faced with the inevitable and ongoing deterioration of existing structures, leading nowadays to the necessary management of maintaining the service conditions and life time extension of bridges. As per the increased amounts of money that can be observed being spent in the countries with an extensive and strong tradition in the development of their infrastructure, the trend can be clearly recognized. The new tendencies turn more and more towards conservation and maintenance, reducing programmed expenses for new construction activities, in line with the already wellestablished territorial structures, as is the case for Spain. This significant heritage of established road infrastructure, consequently containing a vast number of structures, imminently lead to necessary management and maintenance of the including bridges. Under these conditions, this thesis focusses on the status of the development of the management implementation for bridges, current trends, and identifying areas for further development. This also includes the specific application to road networks with limited resources, beyond the national highways. In addition to analyzing the various training methodologies, inventory inspections and condition assessments of bridges, the main objective has been the development of a specific methodology. This methodology, in addition to the traditional system of structure and inspection database training criteria, sustains the classification for the entire road network, according to their condition. This allows, through optimization techniques, for the correct decision making by the technical managers of the network. Among the various methods for assessing the evolution forecast of deterioration of each bridge, a simplified bilinear envelope adjustment made empirical method and Markov models as the most effective solution to address the analysis of predicting the spread of damage, arising from a "technical snapshot" obtained through inspections of the condition of the bridges included in the investigated network. All theoretical basis reflected in the document, is completed by implementing a specific Bridges Management System (BMS), adapted according to the needs and limitations of the authorities for which it has been applied, being in this case particularly the General Highways Directorate of the autonomous region of Castilla-La Mancha, for a representative sample of all bridges in the network in the province of Albacete, starting from a situation where there is currently no formal bridge management system. After an analysis of the state of the art in Chapters 2 and 3, a new deterioration prediction model is developed in Chapter 4, "Deterioration Prediction Model". In the same way, to solve the optimization problem is proposed the use of a singular system of sequential optimization elected under Chapter 5, the "Evolutionary Algorithms", the most suitable mathematical tool to adequately distribute the economic resources for maintenance and conservation for mid-term budget planning. In Chapter 6, and in the various appendices, data and results are presented of the developed application for the analyzed local network, from the optimization model, which guarantees the correct allocation of scarce resources at the disposal of authorities responsible for the regional networks in Spain. The implementation of these systems is witnessed with particular interest for the Spanish secondary network, because of the increasing management responsibility, with decreasing resources. Chapter 7 presents a series of conclusions that triggers to reconsider shifting from theoretical studies and conferences towards a practical implementation, considering how to properly conceive the engineering input and the related education. The original contributions of the document are also listed. In the same way, the research on the Bridges Management System can help evaluating and improving the used systematics.

Espacio web para el diseño de un museo virtual de la historia de la informática

El objetivo principal de crear un espacio web para el Museo Histórico de la Informática (MHI) perteneciente a la Escuela Técnica Superior de Ingenieros Informáticos (ETSIINF) de la Universidad Politécnica de Madrid (UPM) es la difusión de la historia de la informática entre el público en general. Si bien es cierto que existe ya una página web de consulta del MHI con algunas imágenes y contenido sobre los objetos que allí se exhiben, es también reseñable que se trata de un espacio obsoleto, lleno de carencias y extremadamente difícil de gestionar y actualizar, por lo que se hacía imprescindible actualizar el diseño del espacio web, los contenidos y el sistema de gestión de los mismos, cosa que es de gran interés para un lugar divulgativo. En la actualidad, existen maneras mucho más amigables para el usuario de navegar por una web; y de la misma manera para un administrador, gestionar el contenido de la misma y mantener a los usuarios bien informados de todo lo que se ofrece en cada momento. Esto es posible gracias a los sistemas de gestión de contenidos o content management system (CMS), de los que se hablará lo largo de todo el documento. Estos sistemas, dan una facilidad mucho mayor a los encargados de llevar al día una página web, sin tener que saber de programación, lenguajes o informática en general, ya que incorporan paneles de control muy intuitivos y fáciles de manejar, que son una ventaja tanto para ellos como para los usuarios. Es por esta razón que, hay páginas web como la de las empresas IKEA, Ubuntu o, en especial para el caso que compete al documento, el museo del Louvre usan gestores de contenidos para sus páginas web. Y es que las ventajas y facilidades que ofrece un CMS son realmente interesantes y se tratará de todas ellas en el documento, de la elección del CMS que mejor se ajusta a los requisitos del museo, las restricciones a la hora del despliegue en el ámbito de la ETSIINF y de cómo mejorará esto la calidad visual y divulgativa del MHI. Este trabajo se desarrolla a lo largo de 11 capítulos, en los que se muestra como construir un sitio web, las posibilidades y la elección final para este caso. En el primer capítulo se hace una pequeña introducción de lo que es el proyecto, se especifican los objetivos, la motivación del mismo y el alcance que tiene. En el segundo capítulo se muestra la información que se ha recopilado en el trabajo de investigación que se hace previo al desarrollo. En él se muestran los distintos tipos de páginas web, que tecnologías y lenguajes se pueden usar para su construcción, una comparativa sobre otras entidades similares al MHI, las limitaciones que presenta el entorno y la elección final que se consideró más adecuada para este caso. En el capítulo tres se empieza a desarrollar la solución a través del diseño. Aquí se puede encontrar el diseño de más bajo nivel que se le presenta al cliente para sentar las bases del trabajo, el diseño de alto nivel con un mayor grado de realidad que el anterior y una preparación de lo que serán los planes de prueba. El capítulo cuatro muestra todo lo que se ha usado en la implementación y la integración de la página web: herramientas, tecnologías, plantillas de diseño y módulos que proporcionan distintas funcionalidades. Llegados al capítulo cinco, se puede ver una detallada documentación de los resultados de las pruebas de usabilidad y accesibilidad realizadas, y las conclusiones que subyacen de estas. Una vez acabada la implementación del sitio web del MHI, en el capítulo seis se intenta hacer una labor de consultoría, mostrando precios y presupuestos de las distintas tareas que se han llevado a cabo para la realización de este proyecto. En el capítulo siete se extraen las conclusiones de todo lo acontecido en los capítulos anteriores y en el ocho unas líneas sobre posibles trabajos futuros que se podrían llevar a cabo en base a lo que ya se tiene en la institución, incluido este trabajo. Para facilitar la comprensión y satisfacer la curiosidad del lector, se ha incluido en el capítulo nueve la bibliografía con toda la documentación consultada y en el diez un glosario de términos para la aclaración de términos y acrónimos más técnicos. Para acabar, en el capítulo once se anexionan tanto el documento que se usó para las pruebas de usabilidad como un manual de administrador para el sitio web, que hace más amigable el entorno para las personas que lo tengan que mantener en un futuro.---ABSTRACT---The main goal of creating a website for the Informatics Historical Museum (“Museo Histórico de la Informática” or MHI) located in the Higher Technical School of Informatics Engineers (“Escuela Técnica Superior de Ingenieros Informáticos” or ETSIINF) of the Polytechnic University of Madrid (“Universidad Politécnica de Madrid” UPM), is to promote the aforementioned museum as to increase its reach to the public. While it is true that there already is a consulting website with some pictures and information about the items which are displayed in the building, it is outdated and the data is scarce. Moreover, it is extremely complicated to manage and to regularly update the web page, which is very important for informative/broadcasting media. Currently, there are easier ways for the users of a website to consult whatever information they want, as well as it is now easy for a website manager to display new content and to keep the users informed about what is been offered at every moment. This is possible because of content management systems (CMS), which will be discussed throughout the entire paper. These systems make it easier to use for the administrator of a website to keep it up to date without the necessity for them of having any knowledge or skills in programming, languages or computing, because the systems have an intuitive control panel that is easy to use, which is an advantage for both managers and users. Because of all these reasons, there are lots of companies that use this kind of systems, such as IKEA, Ubuntu or, especially, the Louvre Museum, to which we direct our attention all throughout this report. It is easy to notice that these systems have an important and very interesting number of perks and benefits. In the next chapters of the document we will explain the benefits of the program as well as the choice on the kind of CMS that best suits the requirements of the museum and, finally, the restrictions of the school for the deployment and of how all of this will improve the visual and informational qualities of the MHI. This work is developed over 11 chapters, shown how to build up a website, the possibilities and the final choice for this case. In the first chapter a brief introduction of the project, goals, motivation and scope thereof having specified are done. Before the development of the website, the second chapter shows de information of the researching work. It discusses the different types of websites, technologies and languages that can be used for build-up, a comparison of similar entities to MHI, the limitations of the environment and the final choice was considered more appropriate for this case. Chapter three begins to develop the design of the solution. Here there are the lowest level design that presents the customer to fix any problem, the high level design with a higher degree of reality than the last and the test plans. Chapter four shows everything that has been used in the implementation and integration of the website: tools, technologies, design templates and modules that provide different functionalities. Reaching the fifth chapter, you can see a detailed documentation of the results of the usability and accessibility tests made to some users and the conclusions of it. Once the implementation of MHI website is done, in chapter six there is a consultancy work, showing prices and budgets of the different tasks which were carried out for this project. In chapter seven there are the conclusions of what happened in the previous chapters and eight chapter shows possible future works that could be carried out based on what the institution already have, including this work. To make easier to the reader understand this paper and satisfy his curiosity, the chapter nine includes the bibliography consulted with all the documentation and chapter ten has a glossary of terms and an explanation of technical terms and acronyms. Finally, in chapter eleven there are attached both the document that was used for usability testing as a manual administrator for the website, making the environment friendlier for people who have to maintain it in the future.

Diseño web con Drupal 7

En este documento se van a desarrollar las técnicas para la creación de páginas web utilizando uno de los sistemas de gestión de contenido, también llamado CMS, por sus siglas en inglés, Content Manager System, más potentes del mercado, y open source, es decir de código abierto, como es el caso de Drupal. Se usará este sistema de gestión en su versión 7, y la actualización 37, o lo que es lo mismo, se usará Drupal 7.37, aunque se actualizará a la versión 38, puesto que esta versión fue publicada a mitad de los desarrollos y la versión 8 todavía está en versión beta y no es suficientemente estable como para crear una página web robusta con esa versión del CMS. Estas explicaciones están basadas en dos páginas web creadas en dicho gestor de contenidos, una de ellas ya en producción, www.lrl.es, que también podrá ser accedida desde www.luqueagentescomerciales.es, página web diseñada para un agente comercial de herramientas. La segunda, todavía no está en producción pero se puede acceder a ella desde el servidor wamp montado en local, 81.37.0.251/epi, que es una mejora de la página www.elpactoinvisible.es, diseñada para una galería de arte de Málaga. A lo largo del documento se verán distintas opciones que se pueden llegar a utilizar gracias a Drupal para obtener el resultado esperado y se darán las explicaciones pertinentes para saber cuál de ellas usar para focalizar distintos aspectos según se decida ir por una vía u otra de desarrollo, y se mostraran, con código cuando sea necesario, las soluciones utilizadas en las distintas páginas, de las que se ha hablado en el párrafo precedente, y el porqué de usar esa solución en vez de otras alternativas que también son viables para dichos objetivos. ABSTRACT This paper will develop techniques for creating web pages using one of the systems content management, also called CMS, for its acronym in English, Content Manager System, and the most powerful in the market, and open source, as is the case of Drupal. This management system in its version 7, and updating 37, or as it is called, Drupal 7.37 is used, although it will be updated to version 38, because this version was published in the middle of the developments and version 8 is still in beta and is not stable enough to create a robust site with this version of CMS. These explanations are based on two websites created in this CMS, one of them already in production, www.lrl.es, which also can be accessed from www.luqueagentescomerciales.es, web page designed for a tools commercial agent. The second one, is not yet in production but can be accessed from the WAMP server installed locally, 81.37.0.251/epi, which is an improvement to www.elpactoinvisible.es page, designed for an art gallery in Malaga. Throughout the document you can get several options to be used thanks to Drupal in order to achieve result and explanations will be given to indicate one of theme to use for targeting different aspects and which developing method or path to follow and will be shown, in code if it should be necessary, the solutions used in different pages which have been discussed in the preceding paragraph, and why to use that solution instead of other alternatives are also viable for such purposes.

Conceptual Modelling of Complex Network Management Systems

Society, as we know it today, is completely dependent on computer networks, Internet and distributed systems, which place at our disposal the necessary services to perform our daily tasks. Moreover, and unconsciously, all services and distributed systems require network management systems. These systems allow us to, in general, maintain, manage, configure, scale, adapt, modify, edit, protect or improve the main distributed systems. Their role is secondary and is unknown and transparent to the users. They provide the necessary support to maintain the distributed systems whose services we use every day. If we don’t consider network management systems during the development stage of main distributed systems, then there could be serious consequences or even total failures in the development of the distributed systems. It is necessary, therefore, to consider the management of the systems within the design of distributed systems and systematize their conception to minimize the impact of the management of networks within the project of distributed systems. In this paper, we present a formalization method of the conceptual modelling for design of a network management system through the use of formal modelling tools, thus allowing from the definition of processes to identify those responsible for these. Finally we will propose a use case to design a conceptual model intrusion detection system in network.

Benefits of management systems integration: a literature review

The purpose of this paper is to identify the benefits of integrated management systems by comparing them with the benefits obtained through the individual implementation of ISO 9001 and ISO 14001 standards. The methodology used is a literature review based on an electronic search in the Web of Science, ScienceDirect, Scopus and Emerald databases. Findings show that although some benefits are common regardless the system management type, the benefits obtained with integration are greater than considering management systems separately because of the wider scope considered in integration. This is one of the first papers, to the best of our knowledge, to compare benefits from the two management systems standards when implemented separately and when integrated. In addition, some ideas are proposed for consideration in future research on the internalization of management systems and selection effect.

Fragmented coherence: Solid waste management in Colombo

Notwithstanding the increasingly fragmented organizational relationships within Colombo's urban governance system, the cooperative nature of stakeholder relationships lends a high level of coherence to the overall system. Since 1995, Colombo's solid waste management system has been characterized by the increased role of the private sector, community-based organizations and NGOs. Whilst the increasingly fragmented nature of this system exhibits some deeply ingrained problems, there are also a number of positives associated with the increased role of civil society actors and, in particular, the informal sector. Reforming regulatory frameworks so as to integrate some of the social norms that are integral to the lives of the majority of urban residents will contribute to regulatory frameworks being considerably more enforceable than is currently the case. Such reform requires that institutional and regulatory frameworks need to be flexible enough to adapt to the changing social, political and economic context. In the Colombo case, effective cooperation between public sector and civil society stakeholders illustrates that adaptive institutional arrangements grounded in pragmatism are feasible. The challenge that arises is to translate these institutional arrangements into adaptive regulatory frameworks - something that would require a significant mind shift on the part of planners and urban managers.

Scalable location management for context-aware systems

Location information is commonly used in context-aware applications and pervasive systems. These applications and systems may require knowledge, of the location of users, devices and services. This paper presents a location management system able to gather, process and manage location information from a variety of physical and virtual location sensors. The system scales to the complexity of context-aware applications, to a variety of types and large number of location sensors and clients, and to geographical size of the system. The proposed location management system provides conflict resolution of location information and mechanisms to ensure privacy.

Knowledge management applied to enterprise risk management

Risk and knowledge are two concepts and components of business management which have so far been studied almost independently. This is especially true where risk management (RM) is conceived mainly in financial terms, as for example, in the financial institutions sector. Financial institutions are affected by internal and external changes with the consequent accommodation to new business models, new regulations and new global competition that includes new big players. These changes induce financial institutions to develop different methodologies for managing risk, such as the enterprise risk management (ERM) approach, in order to adopt a holistic view of risk management and, consequently, to deal with different types of risk, levels of risk appetite, and policies in risk management. However, the methodologies for analysing risk do not explicitly include knowledge management (KM). This research examines the potential relationships between KM and two RM concepts: perceived quality of risk control and perceived value of ERM. To fulfill the objective of identifying how KM concepts can have a positive influence on some RM concepts, a literature review of KM and its processes and RM and its processes was performed. From this literature review eight hypotheses were analysed using a classification into people, process and technology variables. The data for this research was gathered from a survey applied to risk management employees in financial institutions and 121 answers were analysed. The analysis of the data was based on multivariate techniques, more specifically stepwise regression analysis. The results showed that the perceived quality of risk control is significantly associated with the variables: perceived quality of risk knowledge sharing, perceived quality of communication among people, web channel functionality, and risk management information system functionality. However, the relationships of the KM variables to the perceived value of ERM are not identified because of the low performance of the models describing these relationships. The analysis reveals important insights into the potential KM support to RM such as: the better adoption of KM people and technology actions, the better the perceived quality of risk control. Equally, the results suggest that the quality of risk control and the benefits of ERM follow different patterns given that there is no correlation between both concepts and the distinct influence of the KM variables in each concept. The ERM scenario is different from that of risk control because ERM, as an answer to RM failures and adaptation to new regulation in financial institutions, has led organizations to adopt new processes, technologies, and governance models. Thus, the search for factors influencing the perceived value of ERM implementation needs additional analysis because what is improved in RM processes individually is not having the same effect on the perceived value of ERM. Based on these model results and the literature review the basis of the ERKMAS (Enterprise Risk Knowledge Management System) is presented.

Strategic and operational risk in an international collaboration agency: a knowledge management solution

The International Cooperation Agency (identified in this article as IDEA) working in Colombia is one of the most important in Colombian society with programs that support gender rights, human rights, justice and peace, scholarships, aboriginal population, youth, afro descendants population, economic development in communities, and environmental development. The identified problem is based on the diversified offer of services, collaboration and social intervention which requires diverse groups of people with multiple agendas, ways to support their mandates, disciplines, and professional competences. Knowledge creation and the growth and sustainability of the organization can be in danger because of a silo culture and the resulting reduced leverage of the separate group capabilities. Organizational memory is generally formed by the tacit knowledge of the organization members, given the value of accumulated experience that this kind of social work implies. Its loss is therefore a strategic and operational risk when most problem interventions rely on direct work in the socio-economic field and living real experiences with communities. The knowledge management solution presented in this article starts first, with the identification of the people and groups concerned and the creation of a knowledge map as a means to strengthen the ties between organizational members; second, by introducing a content management system designed to support the documentation process and knowledge sharing process; and third, introducing a methodology for the adaptation of a Balanced Scorecard based on the knowledge management processes. These three main steps lead to a knowledge management “solution” that has been implemented in the organization, comprising three components: a knowledge management system, training support and promotion of cultural change.

Rules for mapping a conceptual model onto various data base management systems. Available in 2 volumes.

The design and implementation of data bases involve, firstly, the formulation of a conceptual data model by systematic analysis of the structure and information requirements of the organisation for which the system is being designed; secondly, the logical mapping of this conceptual model onto the data structure of the target data base management system (DBMS); and thirdly, the physical mapping of this structured model into storage structures of the target DBMS. The accuracy of both the logical and physical mapping determine the performance of the resulting systems. This thesis describes research which develops software tools to facilitate the implementation of data bases. A conceptual model describing the information structure of a hospital is derived using the Entity-Relationship (E-R) approach and this model forms the basis for mapping onto the logical model. Rules are derived for automatically mapping the conceptual model onto relational and CODASYL types of data structures. Further algorithms are developed for partly automating the implementation of these models onto INGRES, MIMER and VAX-11 DBMS.

Planning and implementing safety management systems

This thesis describes a study of the content and applicability of BS8800:1996 Guide to occupational health and safety management systems. The research is presented chronologically, with literature review and content analysis of SMS related guides and standards interwoven with two elements of qualitative empirical work. The first of these was carried out shortly after publication of BS8800 in 1996, a 'before-the-event' investigation of how organisations were intending to approach SMS implementation. The challenges faced by these organisations are reviewed against standard management theory, suggesting that the initial motivation for SMS implementation governs the approach organisations will adopt to guidance such as BS8800. The second phase of empirical work was undertaken in the context of OHSAS 18001, an auditable protocol based on BS8800, which allows organisations to certify their safety management systems. A discussion of the evolution of certifiable safety management system is presented, highlighting the similarities and differences between this, BS8800, SMS and wider management system standards. A case study then reviews the experiences of a catering company that implemented 18001, motivated by the opportunity for certification as a business benefit. The empirical work is used to comment on the guidance provided by BS8800, within its evolved role as guidance organisations may use for implementation of a SMS to be certified according to the specifications of OHSAS 18001. It is suggested that optimal implementation is facilitated by initial status review, continual improvement and the use of annexes, where there are used to make changes to the existing safety management system. This thesis concludes with a discussion of these elements, highlighting pertinent areas within BS8800 where revision or amendment may be appropriate.

A comparison of U.S. and Japanese management systems and their transferability to Singapore industry

This research compares U.S. and Japanese management systems and evaluates their transferability to the Singaporean manufacturing industry. The objectives were:- a) To determine the effectiveness of U.S. and Japanese management systems when applied to Singapore. b) Determine the extent of transferability of U.S. and Japanese management systems to Singapore. c) Survey general problems ecountered in the application of U.S. and Japanese management systems to the Singapore industry. The study using questionnaire survey and interviews covered a total of eighty companies from four groups of firms in four industrial sectors comprising of U.S. and Japanese subsidiaries based in Singapore and their respective parent companies. Data from the questionnaires and interviews were used to investigate environmental conditions, management philosophy, management functions/practices, management effectiveness, and firm productivity. Two-way analysis of variance was used to analyse the questionnaire data. The analysis of the perceptual data from the questionnaire survey and interviews suggested that both U.S. and Japanese parent companies performed better in almost all the management variables studied when compared to their subsidiaries in Singapore. U.S. subsidiaries have less difficulty in adjusting to the Singapore environmental conditions and obtained better results than the Japanese subsidiaries in management functions/practices and management philosophy than the U.S. subsidiaries. In addition, the firm productivity (in terms of labour and capital productivity) of U.S. subsidiaries in Singapore was found to be higher than those of the Japanese subsidiaries. It was found that the Japanese parent companies returned the highest score among the four groups of firms in all the four industrial sectors for all the four management variables (i.e. environmental conditions, management philosophy, management functions/practices, and management effectiveness) surveyed using questionnaires. In contrast, the average score for Japanese subsidiaries in Singapore was generally the lowest among the four groups of firms. Thus the results of this study suggest that the transfer of U.S. management system into the Singapore industry is more successful than the Japanese management system. The problems encountered in the application of U.S. and Japanese management in Singapore were identified and discussed by the study. General recommendations for the Singaporean manufacturing industry were then made based on the findings of the questionnaire survey and interview analysis.

Risk management in organizations:an integrated case study approach

In any organization, risk plays a huge role in the success or failure of any business endeavour. Measuring and managing risk is a difficult and often complicated task and the global financial crisis of the late noughties can be traced to a worldwide deficiency in risk management regimes. One of the problems in understanding how best to manage risk is a lack of detailed examples of real world practice. In this accessible textbook the author sets the world of risk management in the context of the broader corporate governance agenda, as well as explaining the core elements of a risk management system. Material on the differences between risk management and internal auditing is supplemented by a section on the professionalization of risk – a relatively contemporary evolution. Enterprise risk management is also fully covered. With a detailed array of risk management cases – including Tesco, RBS and the UK government – lecturers will find this a uniquely well researched resource, supplemented by materials that enable the cases to be easily integrated into the classroom. Risk managers will be delighted with the case materials made available for the first time with the publication of this book.
