Formal validation of automated policy refinement in the management of network security systems

Policy hierarchies and automated policy refinement are powerful approaches to simplify administration of security services in complex network environments. A crucial issue for the practical use of these approaches is to ensure the validity of the policy hierarchy, i.e. since the policy sets for the lower levels are automatically derived from the abstract policies (defined by the modeller), we must be sure that the derived policies uphold the high-level ones. This paper builds upon previous work on Model-based Management, particularly on the Diagram of Abstract Subsystems approach, and goes further to propose a formal validation approach for the policy hierarchies yielded by the automated policy refinement process. We establish general validation conditions for a multi-layered policy model, i.e. necessary and sufficient conditions that a policy hierarchy must satisfy so that the lower-level policy sets are valid refinements of the higher-level policies according to the criteria of consistency and completeness. Relying upon the validation conditions and upon axioms about the model representativeness, two theorems are proved to ensure compliance between the resulting system behaviour and the abstract policies that are modelled.

Software maintenance project delays prediction using Bayesian Networks

Managing software maintenance is rarely a precise task due to uncertainties concerned with resources and services descriptions. Even when a well-established maintenance process is followed, the risk of delaying tasks remains if the new services are not precisely described or when resources change during process execution. Also, the delay of a task at an early process stage may represent a different delay at the end of the process, depending on complexity or services reliability requirements. This paper presents a knowledge-based representation (Bayesian Networks) for maintenance project delays based on specialists experience and a corresponding tool to help in managing software maintenance projects.

Quality management for vital forest tree seedlings : Final report, Project no: P33854-1

The work concerns development of a prototype molecular tests to identify vitality status of conifer seedlings. The work is done by NSure, Holland, Dalarna University and SUAS. In case for spruce, a successful validation experiment has been performed to validate the identified frost tolerance and vitality genes. Multiple indicators were identified that can be used to either reinforce the existing ColdnSure test, but also for development of a vitality test. The identified frost tolerance and vitality genes for pine still need to be validated. NSure together with Dalarna University aim to perform a validation next season. Multiple LN indicators were identified in spruce that can be used to determine the effectiveness of a LN treatment, but they are not yet validated. In spruce and pine hardly any scientific research is performed to study the effect of a LN treatment, particularly not at molecular level. Therefore NSure together with Dalarna Research Station want to apply for a project. Within this project, we would be able to develop the tests further.

Flood Risk Management In Small Urban River Using A Sustainable Urban Drainage System: Wortley Beck, Leeds, Uk

In the UK, urban river basins are particularly vulnerable to flash floods due to short and intense rainfall. This paper presents potential flood resilience approaches for the highly urbanised Wortley Beck river basin, south west of the Leeds city centre. The reach of Wortley Beck is approximately 6km long with contributing catchment area of 30km2 that drain into the River Aire. Lower Wortley has experienced regular flooding over the last few years from a range of sources, including Wortley Beck and surface and ground water, that affects properties both upstream and downstream of Farnley Lake as well as Wortley Ring Road. This has serious implications for society, the environment and economy activity in the City of Leeds. The first stage of the study involves systematically incorporating Wortley Beck’s land scape features on an Arc-GIS platform to identify existing green features in the region. This process also enables the exploration of potential blue green features: green spaces, green roofs, water retention ponds and swales at appropriate locations and connect them with existing green corridors to maximize their productivity. The next stage is involved in developing a detailed 2D urban flood inundation model for the Wortley Beck region using the CityCat model. CityCat is capable to model the effects of permeable/impermeable ground surfaces and buildings/roofs to generate flood depth and velocity maps at 1m caused by design storm events. The final stage of the study is involved in simulation of range of rainfall and flood event scenarios through CityCat model with different blue green features. Installation of other hard engineering individual property protection measures through water butts and flood walls are also incorporated in the CityCat model. This enables an integrated sustainable flood resilience strategy for this region.

On Real-Time Monitoring And Control For Efficient Management Of Drinking Water Networks: Barcelona Case Study

Drinking water utilities in urban areas are focused on finding smart solutions facing new challenges in their real-time operation because of limited water resources, intensive energy requirements, a growing population, a costly and ageing infrastructure, increasingly stringent regulations, and increased attention towards the environmental impact of water use. Such challenges force water managers to monitor and control not only water supply and distribution, but also consumer demand. This paper presents and discusses novel methodologies and procedures towards an integrated water resource management system based on advanced ICT technologies of automation and telecommunications for largely improving the efficiency of drinking water networks (DWN) in terms of water use, energy consumption, water loss minimization, and water quality guarantees. In particular, the paper addresses the first results of the European project EFFINET (FP7-ICT2011-8-318556) devoted to the monitoring and control of the DWN in Barcelona (Spain). Results are split in two levels according to different management objectives: (i) the monitoring level is concerned with all the aspects involved in the observation of the current state of a system and the detection/diagnosis of abnormal situations. It is achieved through sensors and communications technology, together with mathematical models; (ii) the control level is concerned with computing the best suitable and admissible control strategies for network actuators as to optimize a given set of operational goals related to the performance of the overall system. This level covers the network control (optimal management of water and energy) and the demand management (smart metering, efficient supply). The consideration of the Barcelona DWN as the case study will allow to prove the general applicability of the proposed integrated ICT solutions and their effectiveness in the management of DWN, with considerable savings of electricity costs and reduced water loss while ensuring the high European standards of water quality to citizens.

Organizational design as an enabler for innovation: evidence from a German Mechanical Engineering Company

Over the past two decades there has been a profusion of empirical studies of organizational design and its relationship to efficiency, productivity and flexibility of an organization. In parallel, there has been a wide range of studies about innovation management in different kind of industries and firms. However, with some exceptions, the organizational and innovation management bodies of literature tend to examine the issues of organizational design and innovation management individually, mainly in the context of large firms operating at the technological frontier. There seems to be a scarcity of empirical studies that bring together organizational design and innovation and examine them empirically and over time in the context of small and medium sized enterprises. This dissertation seeks to provide a small contribution in that direction. This dissertation examines the dynamic relationship between organizational design and innovation. This relationship is examined on the basis of a single-case design in a medium sized mechanical engineering company in Germany. The covered time period ranges from 1958 until 2009, although the actual focus falls on the recent past. This dissertation draws on first-hand qualitative empirical evidence gathered through extensive field work. The main findings are: 1. There is always a bundle of organizational dimensions which impacts innovation. These main organizational design dimensions are: (1) Strategy & Leadership, (2) Resources & Capabilities, (3) Structure, (4) Culture, (5) Networks & Partnerships, (6) Processes and (7) Knowledge Management. However, the importance of the different organizational design dimensions changes over time. While for example for the production of simple, standardized parts, a simple organizational design was appropriate, the company needed to have a more advanced organizational design in order to be able to produce customized, complex parts with high quality. Hence the technological maturity of a company is related to its organizational maturity. 2. The introduction of innovations of the analyzed company were highly dependent on organizational conditions which enabled their introduction. The results of the long term case study show, that some innovations would not have been introduced successfully if the organizational elements like for example training and qualification, the build of network and partnerships or the acquisition of appropriate resources and capabilities, were not in place. Hence it can be concluded, that organizational design is an enabling factor for innovation. These findings contribute to advance our understanding of the complex relationship between organizational design and innovation. This highlights the growing importance of a comprehensive, innovation stimulating organizational design of companies. The results suggest to managers that innovation is not only dependent on a single organizational factor but on the appropriate, comprehensive design of the organization. Hence manager should consider to review regularly the design of their organizations in order to maintain a innovation stimulating environment.

The human side of project management - an investigation of critical chain concepts in the Argentinean Project Environment

The global marketplace is rapidly intensifying. Longer product sales lives, greater profit margins or simply survival, is dependent on management¿s ability to create and lead change. Project Management has become an important competency, combined with other business practices to adapt to the trend of changing conditions. Critical Chain is a relatively new project methodology, elaborated by Eliyahu Goldratt in order to complete projects faster, make more efficient use of resources and securing the project deliverables. The methodology is based on the assumption that traditional project techniques such as CPM and PERT, do not recognize critical human behavior. The methodology claims that many project failures are a direct result of how safety is built into the task delivery times, and then wasted by human behavior such as Student Syndrome, Parkinson Law and Multitasking. However, there has been little or no previous research regarding this topic in the Argentine marketplace. This study intended to investigate to what extent the human behavior concepts of critical chain project management are present, by performing in-depth interviews with Argentine project stakeholders. It appears that the four human behavior concepts are present in Argentina and that the majority of Argentine companies are yet to apply project management techniques.

Rio de Janeiro is among the cities with the highest amount of NGOs in the world. However, not all of the projects carried out by the NGOs are equally successful. In this research, I would like to analyze a selection of some of the most well-known social development enterprises operating in Rio, in order to better understand how they operate, what difficulties they face, which factors play the crucial role in achieving peak performance. Moreover, I would like to compare the field research findings with the academic theory on management of social development NGOs, and possibly come up with ideas for further improvements.

Estudos de caso : implantação de sistemas ERP - uma análise crítica à luz da metodologia de Project Management

Este documento constitui-se em uma dissertação de mestrado, requisito parcial para a obtenção do grau de Mestre em Gestão Empresaria e Pública. Este estudo procura mostrar que a adoção dessa nova tecnologia através de projetos de implantação de sistema de ERP não só mudam processos administrativos como também produtos, serviços e estruturas organizacionais e que a sua implantação se constitui em um grande projeto que envolve um número considerável de recursos e tempo das organizações. Este estudo procurar mostrar também que os impactos que tais projetos trazem, são mais fortemente sentidos ou não pela organização de acordo com uma série de fatores, entre eles, a resistência à mudança e o quanto a organização está preparada para enfrentar essas mudanças, o medo da perda do emprego pela adoção de uma nova tecnologia, problemas com a falta de comunicação das mudanças, questões relacionadas à cultura organizacional vigente, a falta de envolvimento da alta administração, entre outras. Para gerenciar todas essas variáveis, as organizações modernas adotam técnicas para garantir o sucesso da implantação dessas novas tecnologias. o estudo aqui proposto tem como objetivo determinar até que ponto a utilização de metodologias e de técnicas de Project Management é o suficiente para que esses projetos alcancem o sucesso esperado pelas organizações. A quantidade de variáveis que influenciam o resultado de um projeto são muitas e cada uma delas possui um papel importante que deve ser avaliado. As conclusões desta pesquisa demonstram que o sucesso de um projeto nem sempre se resume a atingir os objetivos inicialmente propostos, relativos ao cumprimento do prazo, escopo e custo de um projeto, conforme define a metodologia de Project Management. Outros aspectos considerados por essa metodologia, se melhor ou pior aplicados, também contribuem para o sucesso ou fracasso de um projeto de implantação de um sistema de ERP sendo o seu fracasso traduzido ou não, no cumprimento do prazo, do escopo inicialmente previsto ou no custo inicialmente calculado. Outros aspectos que não apenas a aplicação correta da metodologia de Project Management contribuem para os resultados alcançados pelo projeto.

Study of the innovation management process in the development of a discontinuous product case: Motorola RAZR V3

This study will collaborate by bringing some detailed analysis and findings on a special case study of a discontinuous product development process, trying to answer how the discontinuous product development process takes place and the main factors that influence this process. Additionally, it tried to explore some explanations for the difficulties generally faced by the companies to sustain innovation. The case is about the Motorola cell phone RAZR V3, launched in 2004. RAZR V3 was noted by industry experts as game-changing feat of design and engineering, selling more than 110 million units by end of 2008 and recognized as one of the fastest selling products in the industry. The study uses a single case methodology, which is appropriate given the access to a phenomenon that happened inside corporate dominium and it is not easily accessed for academic studies, besides being a rare case of success in the cellular phone industry. In order to magnify the understanding of the phenomenon, the exploration was extended to contrast the RAZR development process and the standard product development process in Motorola. Additionally, it was integrated a longitudinal reflection of the company product development evolution until the next breakthrough product hitting the cellular phone industry. The result of the analysis shows that discontinuous products do not fit well traditional product development process (in this case, stage-gate). This result reinforces the results obtained on previous studies of discontinuous product development conducted by other authors. Therefore, it is clear that the dynamics of discontinuous product development are different from the continuous product development, requiring different treatment to succeed. Moreover, this study highlighted the importance of the management influence in all the phases of the process as one of the most important factors, suggesting a key component to be carefully observed in future researches. Some other findings of the study that were considered very important for a discontinuous product development process: have champions (who believe and protect the project) and not only one champion; create a right atmosphere to make flow the creative process; question paradigms to create discontinuous products; simple guiding light to focus the team; company culture that accepts and knows how to deal with risks; and undoubtedly, have a company strategy that understands the different dynamics of continuous and discontinuous product development processes and treat them accordingly.

Open innovation and the challenges of human resource management

This paper considers challenges of Human Resource Management (HRM) in Open Innovation processes. It examines which strategies managers used to overcome these problems in the case of the Brazilian Oil and Gas company Petrobras. By conducting an inductive case study it develops a contextual model based on the use of grounded theory. It argues that the most important categories were to overcome problems of (a) the interpersonal relationship, (b) power shifting inside the organization, and (c) making people more valuable to the organization and shows how managers tackled these challenges. It contributes with a deep analysis of HRM challenges in Open Innovation that is important for a better understanding of management problems that can come along with Open Innovation processes.

Análise da percepção ambiental como instrumento ao planejamento da educação ambiental

O presente trabalho teve como objetivo realizar um diagnóstico da percepção ambiental da comunidade educativa da Universidade Federal do Rio Grande do Sul (professores, alunos e técnicos administrativos). O estudo da percepção ambiental de uma população é fundamental para compreender as inter-relações da mesma com o seu ambiente. Conhecendo a realidade desta comunidade, pode-se realizar projetos de educação ambiental que atenda as necessidades encontradas nesta população. Conforme a Conferência de Tbilisi, a educação ambiental deve girar em torno de problemas concretos e ter um caráter interdisciplinar. Conforme a Política Nacional de Educação Ambiental, a educação ambiental deve ser tratada em todos os níveis de ensino, formal e informal. Este trabalho foi realizada uma pesquisa quantitativa, baseada em um questionário pré-estabelecido, com uma amostra de 1042 entrevistas. Com a análise dos dados observou-se que a comunidade educativa da UFRGS está preocupada com as questões ambientais, mas está pouco envolvida em ações concretas. A comunidade educativa da UFRGS possui trabalhos que permitem uma análise mais apurada das relações entre a percepção ambiental dessa comunidade e a educação ambiental, como o Relatório de Resíduos Sólidos (GIGA), que trata da gestão dos resíduos produzidos nessa comunidade. Além disso, a UFRGS passa, a partir de 2006, a oferecer um Curso de Graduação em Engenharia Ambiental, o qual pode contribuir significativamente para a consolidação de um processo de educação ambiental e de gestão de resíduos dentro da UFRGS. Este trabalho demonstrou a necessidade de implantação de um projeto de Educação Ambiental na UFRGS, e os resultados desta pesquisa poderão servir como subsídio para a elaboração deste projeto.

Does absorptive capacity affect project performance? A study based on project management practices, organization learning, and knowledge

The literature has emphasized that absorptive capacity (AC) leads to performance, but in projects its influences still unclear. Additionally, the project success is not well understood by the literature, and AC can be an important mechanism to explain it. Therefore, the purpose of this study is to investigate the effect of absorptive capacity on project performance in the construction industry of São Paulo State. We study this influence through potential and realized absorptive capacity proposed by Zahra and George (2002). For achieving this goal, we use a combination of qualitative and quantitative research. The qualitative research is based on 15 interviews with project managers in different sectors to understand the main constructs and support the next quantitative phase. The content analysis was the technique used to analyze those interviews. In quantitative phase through a survey questionnaire, we collected 157 responses in the construction sector with project managers. The confirmatory factor analysis and hierarchical linear regression were the techniques used to assess the data. Our findings suggest that the realized absorptive capacity has a positive influence on performance, but potential absorptive capacity and the interactions effect have no influence on performance. Moreover, the planning and monitoring have a positive impact on budget and schedule, and customer satisfaction while risk coping capacity has a positive impact on business success. In academics terms, this research enables a better understanding of the importance of absorptive capacity in the construction industry and it confirms that knowledge application in processes and routines enhances performance. For management, the absorptive capacity enables the improvements of internal capabilities reflected in the increased project management efficiency. Indeed, when a company manages project practices efficiently it enhances business and project performance; however, it needs initially to improve its internal abilities to enrich processes and routines through relevant knowledge.

Applying DEMO to model and automate a process in a workflow system: a case study in a city hall

Organizations are Complex systems. A conceptual model of the enterprise is needed that is: coherent the distinguished aspect models constitute a logical and truly integral comprehensive all relevant issues are covered consistent the aspect models are free from contradictions or irregularities concise no superfluous matters are contained in it essential it shows only the essence of the enterprise, i.e., the model abstracts from all realization and implementation issues. The world is in great need for transparency about the operation of all the systems we daily work with, ranging from the domestic appliances to the big societal institutions. In this context the field of enterprise ontology has emerged with the aim to create models that help to understand the essence of the construction and operation of complete systems; more specifically, of enterprises. Enterprise ontology arises in the way to look through the distracting and confusing appearance of an enterprise right into its deep kernel. This, from the perspective of the system designer gives him the tools needed to design a successful system in a way that’s reflects the desires and needs of the workers of the enterprise. This project’s context is the use of DEMO (Design and Engineering Methodology for Organizations) for (re)designing or (re)engineering of an enterprise, namely a process of the construction department of a city hall, the lack of a well-founded theory about the construction and operation of this processes that was the motivation behind this work. The purpose of studying applying the DEMO theory and method was to optimize the process, automating it as much as possible, while reducing paper and time spent between tasks and provide a better service to the citizens.
