Strategic risk management in water utilities : development of a holistic approach linking risks and futures

Linares Luis, Ana Margarida January 2014 (has links)
Risk management plays a key role in water utilities. Although tools are well established at operational and tactical levels of management, existing methods at strategic level lack a holistic treatment and a long-term perspective. In fact, risks are analysed per se, despite being interconnected; and long-term scenarios are commonly used for strategic planning, rather than for risk management, most of the time being related to one single issue (for example: climate change). In order to overcome the limitations identified in the existing methodologies, a novel approach for water utilities to manage risk at strategic level was developed and tested in EPAL - the largest and oldest water utility in Portugal. It consists of (i) setting a baseline risks comparison founded on a systemic model developed ‗bottom-up‘ through the business; (ii) the construction of future scenarios and an observation of how baseline risks may change with time. Major contributions of this research are the linkage between operational and strategic risks, capturing the interdependencies between strategic risks; the ability to look at long term risk, allowing the visualizing of the way strategic risks may change under a possible future scenario; and the novel coupling of risks and futures research. For the water sector, this approach constitutes a useful tool for strategic planning, which may be presented to the Board of Directors in a simple and intuitive way, despite the solid foundations of the underlying analysis. It also builds on in-house expertise, promoting the dissemination and pervasiveness of risk management within the companies and, on the other hand, allowing unveiling of existing knowledge, making it explicit and more useful for the organization.

Interactive media - a tool to enhance human communication

Kemshal-Bell, Guy Jonathon, guykb@bigpond.net.au January 2007 (has links)
This exegesis investigates the use of interactive online media to support the development of communication and problem solving skills amongst learners in a Vocational Education and Training (VET) context. It describes the development of the Maelstrom website as a response to the identified need for a collaborative, interactive online space where learners can explore and experiment within the safe and anonymous environment provided. The user interaction within the Maelstrom and user responses to their experiences are discussed and analysed to not only inform the role of the Maelstrom within the broader context on interactive online communication and collaboration, but also to guide future research.

From Delphi To Scenario By Using Cluster Analysis: Turkish Foresight Case

Sakarya, Basak 01 May 2007 (has links) (PDF)
In this thesis, the technologies that appeared to be strategic according to the Vision 2023 Technology Foresight Project were examined in terms of how they might form up technology clusters. This thesis aims to identify technology clusters in terms of common knowledge base and to use these clusters in future scenarios as a foresight tool. In this study, Vision 2023 Delphi survey respondents&rsquo / intersecting expertise levels in different fields were accepted as indicators of common knowledge base in these fields and technology clusters were formed up in this direction. In order to attain technology clusters, the appropriateness of hierarchical and nonhierarchical clustering methods and projection techniques were examined. Taking the clusters into consideration, Ward&rsquo / s method revealed the healthiest results for our data set. Investigation of scenario building which had not been used in Turkey as a an effective foresight tool, forms the second step of this study. Scenario method was examined from a historical perspective and different approaches were investigated. Finally, using the technology clusters that were gained through Ward clustering, a scenario building study by scenario matrix was conducted as an example.

Forest health based scenario building as an accessible tool for climate change management in Bruce Peninsula National Park

Moores, Kelly January 2014 (has links)
The global climate is changing; there are many predictions about the ecological impacts, and even more uncertainty. Predicted ecological impacts include northward shifting biomes, invasive species, decoupling of biotic interactions, all of which are threats to the ecological integrity (EI) of Canada’s National Parks System. To maintain EI, parks must be managed for resilience with climate change in mind. Lack of human and financial resources are restrictions to managing for climate change, challenges exacerbated by government cutbacks in 2012. To overcome these restrictions a tool for informing management in a climate was designed using an existing research program and management based scenario building at the case study location of Bruce Peninsula National Park (BPNP). The tool designed for informing management is called Scenario Building, which accounts for uncertainty and focuses on the essential drivers of the local ecological community. Diversity and health in the forest community are essential drivers in the BPNP ecosystem with interactions at many tropic levels so the forest health research program was selected as the basis for scenarios. Results show a range of tree species that require a variety of soil and moisture regimes. Understanding the ecology of the keystone forest species allows for understanding of how they may reacted to predicted climate changes. Regional climate predictions based on the A2 and B1 primary climate scenarios of the IPCC were integrated with the forest health data, and two levels management option- passive and active to develop 4 scenarios that can inform management of the park. Passive and active management were defined by the number of dollars spent on active management. The 4 scenarios developed were: Scenario 1 B1 Passive Management - Status Quo, Scenario 2 B1 Active Management - Regional Resilience, Scenario 3 A2 Passive Management - Evolving Forests, Scenario 4 A2 Active Management- Anticipatory Restoration. A set of scenarios allows managers to set a management trajectory balances resilience and EI with economic viability in the face of climate change. Analysis of the BPNP scenario suite tell us that BPNP is one park that is in a good position to be able to adapt to a changing climate without major risk to EI, however significant steps can be taken to minimize losses or even improve EI by anticipating needs and investing in active management.

Možné scénáře budoucího vývoje v Mali / Alternative scenarios of future development of the Mali crisis

Hankeová, Tereza January 2012 (has links)
As history is focused on the past and sociology deals with the present, shouldn't be international relations oriented towards the future? On the concrete example of Mali crisis are demonstrated the advantages of the scenario building method, which enhances the relevance of theories of international relations. Northern Mali has been traditionally isolated geographically, politically and economically. Since the beginning of 2012, fights broke out again. The rising threat of Islamist groups was confirmed in the Sahel. This thesis primarily deals with the potential evolution of the Malian crisis, which has been caused by a complex set of interactions. The analysis of events preceding the crisis enables to define driving factors, which will continue to influence the crisis in the future. In addition are defined key uncertainties that could substantially reverse its predictable evolution. Four scenarios outlining alternative future development in northern Mali will be constructed in accordance with a chosen new scenario building method. They differ from each other by varied interactions between key actors and key unknowns and by their temporal and spatial dynamics.

Modèle et outil pour soutenir la scénarisation pédagogique de MOOC connectivistes / Model and tool to support pedagogical scenario building for connectivist MOOC

Bakki, Aïcha 12 December 2018 (has links)
Le travail que nous présentons dans cette thèse s’inscrit dans une problématique générale des EIAH. Il s’intéresse plus particulièrement aux Massives Open Online Courses (MOOC) et concerne plus précisément l’activité de conception de scénarios pédagogiques par des enseignants dans les environnements MOOC connectivistes (cMOOC). Le but principal est de proposer une approche, des modèles et des outils pour assister les enseignants dans le processus de scénarisation et d’opérationnalisation des scénarios pédagogiques dans le contexte des cMOOC. Afin de répondre à ces besoins, la première partie de cette thèse est consacrée à la spécification du processus de création et de déroulement d’un cMOOC. La deuxième partie du manuscrit est consacrée au modèle cORPS de description de scénarios pédagogiques orientés cMOOC.Pour réifier nos propositions, nous avons développé un outil de scénarisation pédagogique adapté au contexte des cMOOC, appelé MOOCAT. Cet outil est doté d’un service de déploiement automatique des scénarios pédagogiques et exploite la notion de workflow à travers la réutilisation et l’adaptation de la notation BPMN. Finalement, l’environnement MOOCAT a été expérimenté auprès de différents publics d’un point de vue utilité et utilisabilité. Les résultats obtenus permettent de confirmer que MOOCAT permet de concevoir des scénarios pédagogiques connectivistes. Les feedbacks des participants ont souligné particulièrement sa simplicité d’utilisation et le bénéfice d’avoir un outil de scénarisation visuelle. / The work presented in this thesis is part of a broader issue of Technology Enhanced Learning (TEL) field. It is particularly interested in Massive Open online Courses (MOOC) environments and concerns more specifically the activity of designing and conceiving pedagogical scenarios by teachers in connectivist MOOC (cMOOC).The main goal is to provide an approach, models and tools to assist teachers in the scenario conception process and the operationalization of pedagogical scenarios in a cMOOC context.In order to meet these needs, the first part of this thesis is devoted to specification of the cMOOC creation and execution process describing the involved stakeholders and the characteristics of each process step. The second part of the manuscript is consecrated to the cORPS model, which describes and defines a cMOOC-oriented pedagogical scenario.To reify our proposals, we have developed an authoring environment for cMOOC context, called MOOCAT. One of the specific characteristics of our tool lies in the exploitation and reuse of the BPMN notation. This tool and the associated operationalization service are covered in the third part of this manuscript.Finally, different publics of practitioners tested MOOCAT notably from a utility and usability point of view. The obtained findings confirm that MOOCAT can be used to design connectivist pedagogical scenarios and provide all the necessary elements for the design of such courses. Feedback from participants particularly highlighted its ease of use and the benefit of a visual authoring tool.

Eenergetinio saugumo scenarijai: Lietuvos, Latvijos ir Lenkijos atvejis / Energy security scenarios: cases of Lithuania, Latvia and Poland

Vaišnoras, Tomas 16 June 2010 (has links)
Susidomėjimas ateities studijomis kaip moksline veikla ypač padidėjo pastaraisiais metais, tai paskatino poreikis prognozuoti galimus socialinius, ekonominius, ekologinius ar politinius pokyčius sparčiai besivystančiame pasaulyje. Socialiniuose bei politikos moksluose prognostiniai metodai ilgą laiką buvo laikomi nepatikimais, tačiau, pastaruoju metu, suvokdami prognozavimą kaip neatsiejamą strateginio planavimo dalį politinių procesų tyrėjai vis dažniau taiko scenarijų konstravimo metodą, mėgindami atrasti galimus ateities įvykių raidos variantus. Patikimas energijos išteklių tiekimas yra vienas pagrindinių valstybės saugumo garantų. Ateities energetikos sektoriaus vystymasis priklauso nuo daugelio kintamųjų, tokių kaip augantis energijos poreikis, aplinkosaugos reikalavimai, technologinis progresas, liberalizavimo procesai ir t.t., todėl norint tinkamai pasiruošti galimiems pokyčiams reikalingas nuoseklus ir racionalus politinis planavimas. Labai svarbu įvertinti būsimus iššūkius, galimybes bei tikėtinas raidos kryptis, o scenarijų kūrimas yra tinkamiausias metodinis įrankis šiems tikslams pasiekti. Pagrindinis darbo tikslas yra sukonstruoti galimus Lietuvos, Latvijos ir Lenkijos energetinio saugumo scenarijus. Norint pasiekti šį tikslą pirmiausiai reikia apsibrėžti energetinio saugumo sąvoką bei scenarijų konstravimo metodą. Svarbu apžvelgti visų trijų valstybių energetikos sektorius, jų stipriąsias ir silpnąsias puses. Kadangi Lietuva, Latvija ir Lenkija yra Europos...

It is influenced by the need to foresee economic, social or political changes in rapidly developing world. For a long time future studies in political and social sciences were considered unreliable. However, in the recent years, foresight became an important part of strategic planning, thus scenario building method is more and more often used by policy analysts. Uninterrupted and reliable energy supply is one of the main pillars of country’s national security. Future development of the energy sector depends on many variables such as the growing energy demand, the technological development, the liberalization of the energy markets etc. Therefore, if countries want to prepare properly for possible changes, consistent and rational political planning is needed. It is very important to assess the future challenges, possibilities and the most likely trends of development, whereas scenario building is the most suitable method for reaching these objectives. The main objective of this research paper is to build possible energy security scenarios for Lithuania, Latvia and Poland. First of all, to achieve this objective one needs to define energy security and scenario building method. It is also important to review the energy sector of each of the three countries, in order to find strengths, weaknesses and main threats to their security. The EU common energy policy has a direct...

La Décroissance au prisme de la modélisation prospective : Exploration macroéconomique d'une alternative paradigmatique / A paradigmatic shift through the prism of prospective modelling : Macroeconomic exploration of degrowth pathways

Briens, François 14 December 2015 (has links)
Face aux enjeux socioéconomiques, démocratiques, et environnementaux, la croissance économique comme fin en soi, ou comme condition nécessaire au « développement », est de nouveau remise en cause. Depuis le début du XXIème siècle, suscitant un intérêt grandissant et de vifs échanges, la Décroissance se fraie une place dans le débat. Après avoir resitué son émergence dans la perspective historique de la controverse qui s'est développée, au cours de la deuxième moitié du XXe siècle, autour de la croissance et du modèle de développement des pays industrialisés, nous suggérons une synthèse des principales idées et des propositions concrètes actuellement portées par ses partisans. Celles-ci soulèvent un certain nombre de questions complexes, pour lesquelles nous proposons d'apporter quelques éclairages à travers un exercice de modélisation prospective. Nous réalisons pour cela une série d'entretiens, qui visent à recueillir différentes visions détaillées et quantifiées de ce que pourraient être, selon les participants, des scénarios de Décroissance, ou - plus largement- des scénarios de transitions souhaitables et soutenables, notamment en termes d'évolution des institutions, des modes de vie et de consommation, pour la France. En parallèle de ces entretiens, nous développons un modèle spécifique de simulation dynamique de l'économie française, construit autour de l'analyse entrées-sorties, sur la base de données publiques, et incorporant un haut niveau de détail. A l'aide de cet outil macroéconomique, nous proposons alors d'explorer, sur un horizon à long terme (2060) les implications possibles de différents scénarios, dont ceux élaborés à partir des entretiens. Nous nous intéressons par exemple aux conséquences possibles en termes d'emploi, de finances publiques, de consommation d'énergie, d'émissions de polluants atmosphériques, et de production de déchets. Les résultats des simulations soulignent l'importance des choix institutionnels, des facteurs culturels, comportementaux, et « non-techniques », et le potentiel de certaines propositions des mouvements de la Décroissance. Ils invitent ainsi à ouvrir le débat autour de la construction collective d'un nouveau projet de société. Dans cette perspective, notre approche offre un support simple et efficace pour la compréhension commune et la délibération collective. / The development paths followed by industrial societies in the last decades have led them in front of complex socioeconomic, democratic and environmental crises, which question the relevance of economic growth, either as a goal in itself, or as a way to achieve “development”. With the emergence of the degrowth movement at the beginning of the 21st century, the call for transitions towards sustainable “post-growth societies” is now consolidating into a multifaceted political project. For the “wealthiest” countries, where the ecological footprint per capita is greater than the global sustainable level, this project may be envisioned as a voluntary, socially sustainable, equitable and smooth downscaling of production and consumption, and thus throughput, to an environmentally sustainable level. Such a project raises numerous questions, for instance: what concrete proposals could initiate such a transition? What could such paths induce in terms of employment, public debt, energy consumption, waste, or greenhouse gas emission mitigation? What structural or institutional obstacles must be overcome and how? Etc. In this research, we offer to discuss such questions with the help of prospective modeling. Our approach involves a series of interviews, conducted, among others, with actors within the Degrowth movement. These are aimed at collecting detailed and quantified visions or narratives about what Degrowth scenarios or – more broadly speaking– scenarios of transition towards sustainable and desirable societies could look like, for France, in the mind of participants, especially in terms of institutions, lifestyles and consumption patterns. In parallel, we have designed and developed a specific dynamic simulation model of the French monetary economy, featuring a high level of detail and disaggregation, based on input-output analysis, and built using public data. Using this macroeconomic tool, we investigate, over the long term (2060), the possible outcomes of different scenarios, including those inferred from the interviews, in terms of employment, public debt, energy consumption, waste and atmospheric emissions. We discuss the potential strengths and weaknesses of the different visions they reflect. Our results highlight in particular the importance of cultural, social, behavioral and “non-technical” factors, stress the potential of various degrowth proposals, and recall the critical need for the collective elaboration of a societal project. In this perspective, our modeling approach provides a simple, yet powerful tool for common understanding and collective deliberation.

No. of bitstreams: 1 Sergio Satt Junior.pdf: 2776264 bytes, checksum: de08438865c711b12dacc3721b268331 (MD5) Previous issue date: 2012-07-06 / Nenhuma / O ambiente empresarial atual apresenta determinados eventos de alta incerteza e de difícil previsibilidade, é necessário que as empresas e seus gestores estejam preparados para atuar em novos e diferentes ambientes de negócios. A mudança no ambiente do refino de petróleo no Brasil iniciou com a abertura do mercado de combustíveis em 1997, Lei 9.478/97. Essa lei propiciou a participação de outros agentes, além da Petrobras, no exercício das atividades de importação e exportação de derivados de petróleo. O segmento de refino no Brasil tem apresentado ciclos de baixa e alta, pois os preços dos derivados nas refinarias não têm sido reajustados na mesma velocidade dos movimentos de preços dos derivados no mercado internacional. Com isso, as refinarias não integradas, é o caso estudado neste trabalho - a Refinaria de Petróleo Riograndense, têm apresentado menor rentabilidade se comparadas com refinarias integradas. Portanto, é necessário identificar eventuais vantagens competitivas que permitam sustentar o negócio deste tipo de refinaria a partir de uma perspectiva de longo prazo. Para tal, foi aplicado o método de construção de cenário Global Business Network (GBN), a fim de criar cenários futuros que apontem alternativas de atuação para uma refinaria de petróleo de baixa escala e não integrada. Além disso, verificar quais as contribuições que o método de construção de cenários GBN trouxe para a empresa e seus gestores. A pesquisa foi caracterizada como qualitativa, exploratória, utilizando o método pesquisa-ação para descrever melhor a construção dos cenários na empresa pesquisada. O resultado da pesquisa foi a geração de dois cenários futuros para a Refinaria Riograndense, onde se apresentam caminhos distintos de atuação no segmento de refino, considerando o ambiente futuro dos negócios e as características da empresa, ou seja, refinaria de petróleo de baixa escala e não integrada. As conclusões do trabalho indicam que o método de construção de cenário GBN contribui para melhorar a percepção da empresa e dos seus gestores sobre o ambiente do futuro do negócio, reduzindo erros no processo de tomada de decisão. Com isso, foi possível apontar caminhos futuros de sobrevivência para a empresa em um ambiente de forte competitividade e restrições ambientais. Também, o método GBN mostrou-se ser flexível às características da empresa, permitindo valorizar os conhecimentos e experiências dos gestores, bem como incentivar o envolvimento dos gestores no processo de construção de cenários. / In the current business environment, there are certain events with high uncertainty that make predictability difficult; thus, companies and their managers must be prepared to act in new and different business environments. Changes in the environment of oil refining in Brazil began with the opening of the fuel market in 1997, since Law 9,478/97 enabled other agents, in addition to Petrobras, to participate in activities related to the import and export of oil products. The refining segment in Brazil has experienced cycles with low and high prices because they have not been adjusted at the same speed as the ones of oil products in the international market. From this perspective, non-integrated refineries were analyzed in this study, mainly the Riograndense Oil Refinery, which has shown lower profitability than integrated ones. Therefore, potential competitive advantages that enable the business to support this type of refinery in the long term were identified. The method of building Global Business Network (GBN) scenarios was applied in order to create future scenarios which can suggest alternatives to a small-scale and non-integrated oil refinery. Besides, the contributions that the method of building GBN scenarios brought to the company and its managers were verified. This qualitative and exploratory research used action research to better describe scenario building in the company. Results generated two scenarios (Maverick and Revolution) for the future of the Riograndense Refinery; they showed distinct paths to be followed in the refining segment, taking into consideration the future of the business environment and the characteristics of the company, i. e., a small-scale and non-integrated oil refinery. The study concludes that the method of constructing GBN scenario helps to improve the perception of the company and its managers about the future of the business environment, reducing errors in the process of decision making. In addition, future directions for the company to survive in an environment with strong competition and environmental constraints could be identified. Furthermore, the GBN method proved to be flexible concerning the characteristics of the company since it valued managers’ knowledge and experience and encouraged them to get involved in the process of scenario building.

Statistical And Spatial Approaches To Marina Master Plan For Turkey

Karanci, Ayse 01 February 2011 (has links) (PDF)
Turkey, with its climate, protected bays, cultural and environmental resources is an ideal place for yacht tourism. Subsequently, yacht tourism is increasing consistently. Yacht tourism can cause unmitigated development and environmental concerns when aiming to achieve tourist satisfaction. As the demand for yacht tourism intensifies, sustainable development strategies are needed to maximize natural, cultural and economic benefits. Integration of forecasts to the strategic planning is necessary for sustainable and use of the coastal resources. In this study two different quantitative forecasting techniques - Exponential smoothing and Auto-Regressive Integrated Moving Average (ARIMA) methods were used to estimate the demand for yacht berthing capacity demand till 2030 in Turkey. Based on environmental, socio-economic and geographic data and the opinions gathered from stakeholders such as marina operators, local communities and government officials an allocation model was developed for the successful allocation of the predicted demand seeking social and economical growth while preserving the coastal environment. AHP was used to identify and evaluate the development, social and environmental and geographic priorities. Aiming a dynamic plan which is responsive to both national and international developments in yacht tourism, potential investment areas were determined for the investments required to accommodate the future demand. This study provides a multi dimensioned point of view to planning problem and highlights the need for sustainable and dynamic planning at delicate and high demand areas such as coasts.
