Texto completoRisk management and corporate social responsibility took roles play how to manage global supply chain energy efficiency strategy and international logistics. All is based on facts-simulations, causes & impacts in transportation, production, and warehouse management”. In term of transportation in global supply chain shows for tracking performance systems hould be applied on appropriate standardized. Particularly for hazardous products. So that, the pollution level can be anticipated and calculated in exact level. The most important one is also the external level, so called leadership factor. This factor will reflect the corporate social responsibility performance.The type of production system which connected to global supply chain system is the most difficult one. Why do we have difficulties on this one? Because, some enterprises or countries for some extent could not make a better choice in term of scarcity for certain type of energy resources. For the warehouse section, the author found the result that electricity sector with real time data base has been giving realistic the way of energy efficiency of global supply chain.The energy efficiency in global supply chain is a perspective that efficiency energy in global level could be perform by any type of product, mainly on energy matter. By focusing on how to transport them, the way of production system, and how to build up warehouse system to keep source of energy become more efficient to serve end users

Texto completoShared situational awareness (SSA) is essential to success and safety in tactical environments, whether fighting wars or providing relief during disasters and humanitarian catastrophes. The increased availability of sensors in mobile devices offers groundbreaking opportunities for continuous context-aware applications that are capable of responding to the operating conditions of users and their environment. However, continuous context-aware applications involve high-energy consumption. A key challenge in tactical environments is to make the most effective use of scarce resources. There are numerous approaches for reducing energy consumption of continuous context-aware applications. This thesis examines two methods: Sensor Substitution and Triggering (SENST) and Acquisitional Context Engine (ACE). The goal of this thesis is to explore the capabilities and limitations of SENST and ACE for group context-awareness and provide a group energy-efficient sensor management strategy that enhances the dissemination of SSA in tactical environments.

Texto completoIn contemporary world, hybrid electric vehicles (HEVs) have shown enormous potential in energy-saving and emission-reducing. By appropriate energy management strategy (EMS), an obvious improvement concerning energy efficiency could be achieved meanwhile self-sustainability is well reserved. Based on a specific HEV prototype Elba developed for Shell Eco-marathon (SEM), relevant research has been carried out by KTH Eco Cars research and development (R&D) teams during recent years. However, because of lack of a proper EMS, Elba meets a bottleneck on improving its energy efficiency and obtaining excellent grade in SEM. To solve this problem, this project is launched to develop a model-based optimization control hierarchy which can be implemented in Elba. Prior to this, some preliminary works have been done, including a set of simplified models of Elba and its powertrain components, and a dynamic programming (DP) based look-up table. Thus, the scope of this project is defined as establishing a complete energy management control hierarchy including three-layer controls. The developing process runs from bottom to top layer. The work starts from refining the original mathematical models according to the newly updated results of components testing and related technical datasheets. Then component-level controllers are developed. Model-based feedforward control together with feedback control for disturbance rejection is employed to replace previous PID control. In the middle layer control, the most significant part in this project, equivalent consumption minimization strategy (ECMS) is employed to realize a properly instantaneous torque split scheme on three propelling components. In this process, optimized fuel consumption among with real-time battery state of charge (SOC) are taken into account. To preserve Elba’s drivability, an improper working mode is identified and rejected to avoid frequent engine switching on/off as well as less efficient energy recuperation. In terms of the infeasibility of the existing DP based look-up table, a reasonable adjudgment function is introduced to complement its functionality. Thus, the modified look-up table is able to provide rational acceleration reference acting as top layer control. The whole work is finished in MATLAB/Simulink platform. The simulation results indicate that, compared with the previous control strategy, the new one significantly improves energy efficiency and better preserves battery SOC. Indeed, these decent results are on basis of some ideal assumption and simplified models. As an attempt on research and development of optimization control strategy, some precious experience and achievements have been, after all, obtained during the thesis work. All these will be verified by field tests and will promote Elba’s further upgrading in the future.

Texto completoENGLISH ABSTRACT: This research study explored energy efficiency and the possible implications for a South African company, the Pioneer Foods Group (Pioneer Foods). “What value could Pioneer Foods derive from an energy efficiency strategy?” is the research question posed in this study. The case study analysis revealed that Pioneer Foods recently listed on the Johannesburg Stock Exchange and therefore needed to implement an environmental management strategy as part of their carbon footprint reporting. Energy efficiency turned out to be one aspect that could have a significant impact on their carbon footprint. The most important barrier to energy efficiency identified at Pioneer Foods was found to be the lack of real-time electrical consumption information as this could result in a lack of ownership taken by mill management. Further barriers included the use of wrong information for benchmarking purposes as well as a possible misunderstanding of the different electricity tariffs shown on the electrical utility bill. Possible ways to overcome the barriers to energy efficiency at Pioneer Foods included installation of energy meters for real-time monitoring of the energy consumption, empowerment of people to ensure buy-in, as well as key performance indicators for mill managers linked to energy efficiency. It was suggested that the energy efficiency strategy be implemented in stages covering short-term, medium-term and long-term objectives. This way the implementation process would seem less intrusive to people and also give the energy efficiency team the opportunity to learn more and perhaps adjust the strategy throughout the implementation process. This research project should act as a starting point for Pioneer Foods to grow from being unconsciously incompetent to becoming consciously competent in the field of energy efficiency. The observations made throughout this study, should convince companies that energy efficiency should not just matter to high energy users. All companies should explore their own drivers for implementing energy efficiency and act on it.
AFRIKAANSE OPSOMMING: Hierdie navorsingstudie het die effektiewe gebruik van energie, en die moontlike implikasies vir ‘n Suid Afrikaanse maatskappy, die Pioneer Voedsel Groep (Pioneer Voedsel) ondersoek. “Watter waarde sou Pioneer Voedsel kon put uit ‘n energie-effektiwiteit-strategie?” is die navorsingsvraag wat in hierdie studie gestel is. Uit die analise blyk dat Pioneer Voedsel onlangs op die Johannesburgse Effektebeurs genoteer is. Daar word dus van hulle verwag om ‘n omgewingsbestuur-strategie in plek te stel as deel van hul koolstofvoetspoor-verslaggewing. Dit blyk dat energie-effektiwiteit een aspek is wat ‘n groot impak op hulle koolstofvoetspoor kan hê. Die grootste struikelblok tot energie-effektiwiteit by Pioneer Voedsel geïdentifiseer, was die tekort aan intydse elektriese verbruiksinligting. Dit kan veroorsaak dat die bestuur nie eienaarskap neem van energie-effektiwiteit nie. Verdere struikelblokke sluit in die gebruik van foutiewe inligting vir metingsdoeleindes asook ‘n moontlike gebrek aan begrip van die verskillende elektrisiteitstariewe uiteengesit op die elektrisiteitsrekening. Moontlike maniere om die struikelblokke by Pioneer Voedsel te oorkom sluit in die installasie van energiemeters vir intydse monitering van energieverbruik, bemagtiging van mense om inkoop te verseker, en sleutelprestasie-aanwysers vir bestuurders gekoppel aan energie-effektiwiteit. Dit word voorgestel dat die energie-effektiwiteit-strategie in fases geïmplementeer word om sodoende kort-, medium- en langtermyn-mikpunte te bereik. Sodoende sal die implementering van die proses minder indringend vir personeel wees. Dit gee ook die energie-effektiwiteit-span die kans om meer te leer asook die strategie aan te pas soos nodig tydens die implementeringsproses. Hierde navorsingsprojek moet dien as die vertrekpunt vir Pioneer Voedsel om te groei van onwetend onbekwaam tot wetend bekwaam in die veld van energie-effektiwiteit. Verder behoort dit maatskappye te oortuig dat energie-effektiwiteit nie net ‘n verskil maak vir hoë energie verbruikers nie, maar dat alle maatskappye hulle eie drywers vir die implementering van energie-effektiwiteit behoort te identifiseer en daarvolgens aksiestappe te neem.

Texto completoTraditionally organizations have reported largely on financial information. The Global Reporting Initiative and the King III Code of Corporate Governance have become important guidelines in assisting organizations on how to report and consequently integrated reporting is quickly gaining popularity. As the potential effects of climate change and other environmental and social impacts of businesses become more apparent, stakeholders are placing pressure on these organizations to be more transparent in how they are dealing with these impacts. Strategy cannot be separated from sustainability (SAICA, 2009: 7); therefore there is increasing pressure on organizations to disclose their strategies. Not all companies disclose information relating to strategy and sustainability to the same extent. There are a range of factors that influence strategy disclosure. This study updates the 2010 study (Meyer, 2011) evaluating the extent of strategy disclosure in the energy and natural resources sector of five companies (BP, Eskom, Mondi, Sappi and Sasol) using a three-point evaluation scale. In addition the following analyses were done: A benchmarking exercise comparing the strategy disclosure and sustainability reporting of the five companies analysed against two industry leaders (Repsol and Enagas). Development of the drivers of strategy disclosure from the literature which were compared to the results from the three-point evaluation scale. The analysis was repeated using a six-point evaluation scale, as this more clearly determined the extent of strategy disclosure, which was then compared to the drivers of strategy disclosure. The results, obtained from the six-point evaluation scale, supported the drivers of strategy disclosure and concluded that product type, the competitive environment and risk are some of the main determinants of strategy disclosure in this study based on the companies evaluated. It was also concluded that, based on the three-point and the six-point evaluation scale, the average level of disclosure for the energy and natural resources sector is good, and had improved from 2010. Furthermore, it was also observed that strategy is not disclosed to the same extent as sustainability information. Baseline One had more of a focus on sustainability information, whereas Baselines Two and Three focussed more on strategy. The level of disclosure in Baseline One was more than that of Baselines Two and Three.

Texto completoIn this paper, the energy company Kraftringen Energi AB has been discussed, according to the purpose to investigate the strategies they use at a storm with a focus on their use of social media, Facebook. In addition, also a comparison was made to see if their work differs from the work that was done before the rebranding as Kraftringen Energi AB underwent two years ago with the work they do today, with a focus on the communication to their customers in during a storm. There was also a hope to present proposals for improvement, which the company can use in their future work.To implement this, the research case study method used, and where the focus has been on the information that emerged during the six semi-structured qualitative interviews were made that had a targeted selection of interview subjects. The materials developed during the interviews were then compared with the previous research and theory, but also with the content analysis made by the company's Facebook page during the storm Sven.The conclusion that has been developed with the help of the discussion shows that today there are strategies on how the work on this should work in a storm, which thus also become one of the suggestions for improvement that have been developed along with adding a charge of this task. There was also no significant difference in the work that was done before the brand transition to what is done today by a storm, beyond that the company uses Facebook. One idea that has been presented to this is to conduct training on the approach available today to find new improvements to it. But also that the company should consider developing strategies how their Facebook page to be used and if there is to be a responsible person for this page, as well as their other social media.

Texto completoThe global energy industry is actively moving toward renewable energy sources in order to meet the ever-increasing demand for energy in a sustainable manner. The South African government, however, has only recently begun creating an environment which is truly conducive to investment into the renewable energy industry. Metso, a Finnish multi-national corporation, has a strong global position in the field of biomass-based power generation for heat, power or combined heat and power applications. The corporation has developed a modular biomass-based power generation solution for power generation in the 3MW to 10MW range, which is highly automated and can essentially operate without the need for extensive human intervention and is known as the Metso Bio-energy Solution. Considering the current state of the South African energy environment, Metso management requested the researcher to investigate the opportunities that exist in the South African market for Metso’s Bio-energy Solution, and to propose a market entry strategy which Metso should follow in order to enter the South African market. In the findings, the researcher observed that South Africa has a clear potential for the development of a bio-energy industry for power generation, although the limited availability of biomass in certain regions and the various harvesting methods in industries such as the forestry and sugar industries do restrict the access to this resource. The municipal solid waste industry appears to be an area of interest as well, although very little information exists regarding the volumes of waste available and sorting practices, which may be required in order to access these resources. Interviews were held with experts in the field of energy, renewable energy and energy policy in order to obtain opinions on the market potential for Metso’s Bio-energy Solution. The general perception of all interviewees was that the technology has its place within the South African energy mix. The interviewees, however, did confirm that there currently appears to be a major focus on wind and solar energy in the country, although biomass technology may well be a better solution due to its baseload capabilities. It was found that the local policy environment, the lack of government initiative on renewable energy licensing and unclear tariff structures have all inhibited the proliferation of the renewable energy industry. In many cases, frustration with power outages and policy delays has caused companies to invest in biomass co-firing facilities for their own consumption. The factors for success for biomass-based technologies in the South African market would appear to be directly linked to job creation potential, access to reliable and sustainable biomass resources and access to investment capital, from both private equity and the state. It is the recommendation of the researcher that Metso enters into a joint venture with a large international environmental finance company, which would base their business model on the technology provided by Metso, whilst securing the political and financial support for projects of this nature in the country.

Texto completoAs a University that has been low rated amongst government agencies 2009, today KTH has a vision to become one of Europe’s leading universities in sustainable development. The aim with this paper is to investigate the energy consumption at KTH from a systems perspective. Another purpose is that the result could be used as a guideline for future work. The paper involves mapping of the energy consumption in the schools of KTH and a description of the current state regarding the energy work. Further, an interview survey has been performed in order to achieve a better understanding of how Akademiska Hus and KTH relates to the energy topic. The mapping shows that all schools shows a reduction in their energy consumptions, where ABE by the year 2015 has an energy consumption of 3988 MWh which is a decrease by 30 % compared to 2011 (5690 MWh). The lowest reduction is shown by ICT which counts to 8 %. The total energy consumption coming from facilities at KTH is counted to approx. 188 GWh. The result of this paper shows that the environmental work of KTH have not been on a satisfying level and that the current rental model between KTH and Akademiska Hus does not encourage progress in the energy topic at KTH. Further, it is proven that Akademiska Hus and KTH have different levels of ambition in the energy matter, and that the energy reporting tool that is provided to KTH has clear improvement potentials, where a distinction between property – and operation electric is one of them. This would allow clearer follow-ups of the energy goals in KTH, which is not the case today. A summary of improvement suggestions from the conclusions of the study are: Create a counterpart at KTH to the energy strategist at AH that could facilitate the communication between the parties and highlight the energy issues at KTH. Start a discussion concerning the rental model and improve it, to create incentives for energy savings mainly at the KTH side. Develop and introduced an improved energy reporting tool.

Deregulation shaping the Electricity industry across the world is a systems challenge cutting across interdisciplinary fields of technology, economics, public policy, environment and sociology. Decision makers that shape tomorrow's policy and investors that invest in financial and technological developments in this industry need to rely on multiple decision models to make informed decisions. This thesis serves to provide one such decision model among many that could be used to understand the key dynamics shaping a highly complex industry. We employ "top-down" and "bottom-up" approaches to build system dynamics model in an attempt to distinguish between adoption and diffusion phenomenon, as a result benefiting from hybrid modeling techniques that combine structures from both models. The models are evaluated with wide range of scenarios to arrive at policy guidance and business model recommendations. The dynamic hypothesis arising from our system dynamics model points to declining marginal profits in a saturating market coupled with proliferation of competitors, over-estimation of demand and diminishing margins for Curtailment Service Providers (CSPs) in the long run. We propose recommendations to surmount these challenges. To tap the smaller commercial and residential markets, CSPs must extend its reach by partnering with composite channel partners, who in the long run could also play a vital role in demand generation. In the face of commoditization and disruptive innovations, CSPs would not be able to sustain their margins just by aggregating demand response (DR) capacity, they would need to reinvent themselves to become energy management firms providing integrated, automated turnkey energy services including energy efficiency services, risk management, planning, sourcing along with providing DR services. Taking a systems approach in evaluating demand-side technology, we further investigate environmental implications of DR by characterizing the carbon savings from DR. Our analyses revealed that the carbon savings from DR triggered load curtailment when calculated using system wide carbon intensities differ substantially from those calculated with locational carbon intensities. Locational carbon intensity captures the location and time-specific dynamics of electricity demand. We, therefore, recommend it is a better metric for evaluating total carbon savings from load curtailment, which could be used to devise carbon abatement policies and structure the electricity market design rules. Furthermore, adding a carbon price to the marginal cost equation could change the dispatch order of plants and thus align carbon abatement policies with load reduction schemes.

Texto completoInitiatives to decrease emissions from the transport sector are increasing worldwide by seeking alternative technologies to replace oil-based mobility. Battery Electric Buses (BEB) present a promising solution thanks to their high energy efficiency, low greenhouse gas emissions and the absence of local pollutant emissions. However, this technology still faces many challenges, especially its high total cost of ownership (TCO) and other operational factors such as the limited bus driving range, the high energy refueling time, and the required charging technologies and strategies. In this context, this thesis presents a systematic methodology that aims at developing solutions to help overcoming these challenges by providing optimal battery sizing and charging strategy for BEB. First, a comprehensive multi-physical bus energy model is developed to evaluate its energy needs considering all the energy systems encountered within. The energy consumption of the bus is then evaluated at a variety of operating conditions. Then, a techno-economic model of an entire bus line is developed in order to assess the impact of different battery sizing and charging strategies on the costs and operation of BEB. A TCO model is introduced considering the BEB unit costs, battery purchase and replacement costs, energy and power costs, infrastructure, and maintenance costs. A case study in Paris city is presented and the analysis reveals the resulting tradeoff between the TCO and BEB schedule disruptions and delays as function of different battery sizes and charging strategies. A methodology to minimize the TCO of BEB deployment is presented providing the optimal battery sizing and charging strategy for BEB, while respecting the BEB operation constraints. The methodology is a 2-step optimization algorithm that utilizes both Dynamic programming and Genetic Algorithm optimization routines. The results show that the proposed methodology could reduce the BEB TCO between 15-25% compared to the currently adopted approaches to deploy BEB

A hybrid electric vehicle with an engine on the front axle and an electric motor on the rear axle is analyzed. A control strategy is developed based on a set of rules with different modes depending on the vehicle speed and accelerator pedal position, switching between using only the electric motor, only the engine, and a combination of both. The control strategy increases fuel economy while maintaining the charge level of the hybrid battery pack and providing a smooth and enjoyable driving experience.

Texto completoThis PhD thesis proposes Energy Management Strategies conceived for a hybrid electrical urban bus. The hybrid control system should create an efficient strategy of coordinating the flow of energy between the heat engine, battery, electrical and hydraulic motors. Firstly, a Deterministic Dynamic Programming (DDP) based approach has been proposed: simultaneous speed and powersplit optimization algorithm for a given trip (constrained by the traveled distance and time limit). This algorithm turned out to be highly time consuming so it cannot be used in real-time. To overcome this drawback, an Optimal Profiles Database based on DP (OPD-DP) has been constructed for real-time application. Afterwards, a Stochastic Dynamic Programming (SDP) technique is used to simultaneously generate an optimal speed profile and related powersplit strategy. This approach takes into account a stochastic nature of the driving behavior and urban conditions. The formulated energy optimization problem, being intrinsically multi-objective problem, has been transformed into several single-objective ones with constraints using an ε-constraint method to determine a set of optimal solutions (the Pareto Front).In urban environment, due to traffic conditions, traffic lights, a bus encounters frequent Stop&Go situations. This results in increased energy consumption during the starts. In this sense, a relevant Eco Adaptive Cruise Control with Stop&Go (eACCwSG) strategy brings the undeniable benefit. The algorithm smooths speed profile during acceleration and braking phases. One more important feature of this algorithm is the safety aspect, as eACCwSG permits to maintain a safety distance in order to avoid collision and apply a smooth braking. As it was mentioned before, smooth braking ensures passengers comfort

Texto completoIn clusters and virtualized data centers, the resources must be managed effectively by maximising the SLA fulfilment while minimising the cost. This work proposes a strategy for dynamic resource allocation in virtualized computing environments in order to reduce energy consumption without compromising performance requirements concerning availability and SLA violation. The proposed algorithms, based on classical heuristics, perform virtual machines migration between distinct hosts according to the variation in resources demand. These algorithms were evaluated from measurements in a real environment composed by heterogeneous virtualized hosts. We evaluate their performance in four different scenarios based on the CPU and memory utilization, number of migrations and energy consumption. In general, the results show that the algorithms responsible for consolidation and distribution of virtual machines between hosts are able to reduce energy consumption and dissipate the idle and overload points.
Em clusters e data centers virtualizados, os recursos precisam ser gerenciados com eficÃcia na busca de um trade-off entre a garantia de um atendimento satisfatÃrio à demanda por Qualidade de ServiÃo (QoS) e a reduÃÃo dos custos operacionais por parte dos provedores. Este trabalho propÃe uma estratÃgia para alocaÃÃo dinÃmica de recursos em ambientes computacionais virtualizados com vistas à reduÃÃo do consumo de energia, sem promover sobrecargas que podem comprometer o desempenho dos serviÃos ofertados. Os algoritmos propostos, baseados em heurÃsticas clÃssicas, realizam migraÃÃo de mÃquinas virtuais entre servidores distintos conforme variaÃÃo na demanda por recursos. Estes algoritmos foram verificados e validados por mediÃÃes em um ambiente real composto por servidores virtualizados heterogÃneos. O desempenho da proposta à avaliado em quatro cenÃrios distintos a partir das mÃtricas utilizaÃÃo de CPU, utilizaÃÃo de memÃria, nÃmero de migraÃÃes e consumo de energia. Os resultados mostraram que os algoritmos responsÃveis pela consolidaÃÃo e distribuiÃÃo das mÃquinas virtuais sÃo capazes de reduzir o consumo de energia e dissipar os pontos de Ãcio e sobrecarga do ambiente.

Texto completoENGLISH ABSTRACT: Red Bull is probably one of the most interesting brands ever created. Since its launch in Austria in 1986 and the launch in South Africa in November 1997, Red Bull has caused a stir. Dietrich Mateschitz created Red Bull after visiting Thailand and seeing the taxi drivers drinking syrup called Kraling Daeng. He took this mixture to his home country and started to develop something more acceptable to the Western taste. The Red Bull brand was developed and built by firstly developing the taste, then designing the can and lastly designing the famous cartoons. Only thereafter the rollout started. Red Bull created a new drinks category called energy drinks. This research will take a close look at and discuss how Red Bull used the strategic marketing process to decide whether to enter the South African market, and from a marketing point of view, how the brand was and still is managed, focusing specifically on the first ten years since its launch in South Africa. Red Bull hit the South African shops in November 1997. This happened after a local distributor, THUMB Trading and later J Melnick & Company, did some analysis about the market. This industry, political, economic, social, technical and environmental analysis showed that the brand could be successful in the country. The volatile and ever changing exchange rate and import duties would however be the biggest external factors affecting the pricing in South Africa. Red Bull Head Office together with the local distributor investigated the market size and market potential, concluding that there was huge potential to launch the product in South Africa. The distributor at the time, THUMB Trading, was a consumer goods importer with good knowledge of the market. Their distribution and penetration into the retail market was solid although they lacked in the newly identified on-premise market. A new team was established to service this on-premise market, which was Red Bull 's focus when entering the market, supported by consumer sampling. The first phase, getting the silver and blue can into all the trendy and well-known on-premise outlets, was very successful but soon the next phase of rolling the brand out to the retail and convenience stores needed to commence. This coincided with even more consumer awareness programs across the country. The marketing activities soon followed, not in the traditional 4 Ps style of price, product, place and promotion, but something quite different. Red Bull introduced their methodology looking at the brand based on five pillars - media, sport and events sponsoring, consumer collecting, trade and retail promotions, and market research. These pillars each have their specific goals closely interacted to form an integrated marketing approach. Red Bull has unique brand events such as Boxcart and "Flugtag" (Flying day) to create the awareness and fun around the brand. These events are held in popular and spectacular locations, which attract tens of thousands of spectators to witness the brand at first hand. The Red Bull sponsored and supported athletes help to promote the functionality of the brand by helping athletes (and other consumers) with endurance, recovery, concentration and focus in time when they need it most. The marketing mix also consists of trade and retail promotions where Red Bull has developed specific point-of-sale items for the different channels. The category management and "global score" projects further enhance the Red Bull visibility, resulting in increased sales. Red Bull looks at the marketing spend on a monthly basis making sure it is progressing according to the budget. Any deviations found in the control process are carefully analysed and the adjustments are made accordingly. The local marketing team has to submit a revision at the end of each quarter making sure they stay on track according to the Annual Business Plan approved in December of the previous year. Monthly feedback is given to the country manager or Quarterback and Area Manager in the marketing and sales report on all development according to a predefined set of targets. The Red Bull sales and marketing efforts in South Africa are not only supported by local marketing efforts but also by Red Bull Head Office's international marketing strategies. These include Red Bull projects such as the channel crossing, the Jesus statue jump and world record speed skiing attempts to name but a few. The Red Bull companies with the well-known Red Bull Racing and Torro Rosso respectively competing in the Formula One Grand Prix series, Hangar 7 housing the Flying Bulls or the Red Bull Air Race, also contributes to keep the brand in consumers minds. Red Bull is truly a different brand with unique ways of doing business. The planning and thinking integrate not only the different pillars but also the head office projects, and Red Bull companies make the marketing effort something special to watch. This integrated marketing approach comprising of so many different angles sets new marketing standards, and also makes it easier to understand why the brand is so strong globally. The Red Bull success can be attributed to a small number of things, which include their people,the passion for the brand, a drive to succeed, and their detailed planning methodology. The way of doing is consistent throughout the world, speaking the same language with the same message everywhere - a unique brand with strong brand values, focus and strategies, which thinks as a number two to be the number one ......

AFRIKAANSE OPSOMMING: Red Bull is waarskynlik een van die mees interessante handelsname wat ooit geskep is. Sedert die bekendstelling in Oostenryk in 1986 en die bekendstelling in Suid-Afrika in November 1997, het Red Bull 'n beroering veroorsaak. Dietrich Mateschitz het Red Bull ontwerp nadat hy Thailand besoek het en daar gesien het dat taxi-bestuurders 'n stroop, genaamd Krating Daeng, drink. Mateschitz het hierdie mengsel na sy tuisland teruggeneem en begin om iets te ontwikkel wat meer aanvaarbaar vir die Westerse smaak sou wees. Die Red Bull handelsmerk is ontwikkel en uitgebou deur eerste die smaak te ontwikkel, daarna die blikkie te ontwerp en laastens die welbekende tekenprente. Slegs daarna het die bekendstelling begin. Hierdie navorsing sal in diepte kyk en bespreek hoe Red Bull die strategiese bemarkingsproses gebruik het in die besluit om die Suid-Afrikaanse mark binne te dring al dan nie en vanuit 'n bemarkingsoogpunt bespreek hoe die handelsmerk bestuur is en steeds bestuur word deur spesifiek te fokus op die eerste tien jaar vanaf bekendstelling in Suid-Afrika. Red Bull is in November 1997 in Suid-Afrikaanse winkels beskikbaar gestel. Dit het gebeur nadat 'n plaaslike verspreider, THUMB Trading, later bekend as J Melnick & Company, 'n markanalise gedoen het. Hierdie industrie, politieke, ekonomiese, sosiale, tegniese en omgewingsanalise het gewys dat die handelsnaam baie suksesvol in die land kon wees. Die onbestendige en ewig veranderende wisselkoers asook invoerbelasting sou egter die grootste eksterne faktore wees wat betref die prysbepaling vir die Suid-Afrikaanse mark. Red Bull hoofkantoor, tesame met die plaaslike verspreider het die markgrootte en markpotensiaal ondersoek en tot die gevolgtrekking gekom dat daar baie potensiaal is om die produk in Suid-Afrika vry te stel. Die verspreider, THUMB Trading, was 'n invoermaatskappy van verbruikersgoedere met 'n grondige kennis van die mark. Hul verspreiding en penetrering van die handelsmark was bestendig, alhoewel hulle tekortgeskiet het in die nuut geidentifiseerde "op-perseel"-mark. Red Bull wou spesifiek fokus op die "op-perseel"-mark asook verbruikersmonsters terwyl die mark betree word en daar is toe 'n span saamgestel wat hierdie "op-perseel"-mark sou diens. Die eerste fase, om die silwer-en-blou-blikkie in al die gewilde, toonaangewende "op-perseel" verkooppunte beskikbaar te stel, was baie suksesvol, maar kort daarna moes die volgende fase begin - om die produk in die kleinhandelafsetpunte en gerieflikheidswinkels te hê. Hierdie fase het saamgeval met selfs nog meer gebruikersbewusmakingsprogramme oral deur die land. Die bemarkingsaktiwiteite het kort daarna gevolg - nie in die tradisionele 4 P-styl van prys, produk, plek en promosie nie, maar iets heeltemal eiesoortig. Red Bull het hulle metodologie bekendgestel wat daarop berus dat hulle die bemarking van die handelsmerk op vyf pilare basseer: media, sport en geleentheidsborgskappe, verbruikersversameling, handel- en kleinhandel promosies, asook marknavorsing. Hierdie pilare het elk sy eie spesifieke doelwitte met noue wisselwerking tussen mekaar om uiteindelik 'n geintegreerde bemarkingsbenadering te vorm. Red Bull bied unieke okkasies, soos "Boxcart" en "Flugtag" (Vliegdag) aan om bewusmaking en pret rondom die handelsmerk te verhoog. Hierdie okkasies word in gewilde, skouspelagtige plekke aangebied wat tienduisende toeskouers teiken wat die handelsmerk eerstehands kan ervaar. Atlele wat deur Red Bull geborg en/of ondersteun word, help om die funksionaliteit van die handelsnaam te bevorder deur atlete, asook ander verbruikers, te help met hul uithouvermoë, herstel, konsentrasie en fokus op die tye wat hulle dit die nodigste het. Die bemarkingsaktiwiteite sluit ook in handels- en kleinhandelpromosies waar Red Bull spesifieke verkooppunt-items ontwikkel het vir die verskillende kanale. Die kategorie bestuur- en globale puntestandprojekte bevorder die Red Bull sigbaarheid wat weer lei tot verhoogde verkope. Red Bull kyk maandeliks na die bemarkingsbesteding om sodoende te verseker dat dit volgens die begroting verloop. Enige afwykings wat tydens die kontrole proses gevind word, word baie deeglik geanaliseer en aanpassings word gemaak. Die plaaslike bemarkingspan moet elke kwartaal 'n revisie indien om te verseker dat hulle op die regte spoor bly aangaande die Jaarlikse Besigheidsplan wat Desembermaand van die vorige jaar goedgekeur is. In die bemarkings- en verkoopsverslag word maandeliks terugvoer aan die landbestuurder en areabestuurder gegee rakende alle vordering op grond van 'n voorafgedefinieerde stel doelwitte. Die Red Bull verkoop- en bemarkingsprestasies in Suid-Afrika word nie net deur plaaslike bemarkingspogings ondersteun nie, maar ook deur Red Bull hoofkantoor se internasionale bemarkingstrategiee. Hierdie sluit projekte in soos die kanaaloorkruising, die Jesusbeeld-sprong en wereldrekord spoedskipogings, om maar net 'n paar te noem. Die Red Bull maatskappye, tesame met die welbekende Red Bull Racing en Torro Rosso wat afsonderlik deelneem aan die Formule Een Grand Prix-reeks, die Hangar-7 wat die Vlieende Bulle of die Red Bull Lugspan huisves, dra almal daartoe by om bewusmaking van hierdie handelsnaam by verbruikers te verhoog. Red Bull is verseker 'n andersoortige handelsnaam wat op 'n unieke manier besigheid doen. In die beplanning- en oorwegingsfase word nie net die verskillende pilare geintegreer nie, maar ook die projekte wat deur die hoofkantoor geloods word en die Red Bull maatskappye maak die bemarkingsprojek iets besonders om te sien. Hierdie geintegreerde bemarkingsbenadering wat uit soveel verskillende fasette bestaan, stel nuwe bemarkingstandaarde, maar maak dit ook makliker om te begryp waarom hierdie handelsnaam wereldwyd so sterk is. Die sukses van Red Bull kan toegeskryf word aan 'n paar dinge, wat insluit hul mense, die passie vir die handelsmerk, die deursettingsvermoe om suksesvol te wees, asook hul gedetaileerde beplanningsmetodologie. Die manier van doen is wereldwyd konsekwent, praat oral dieselfde taal met dieselfde boodskap - waarlik 'n unieke handelsnaam met sterk waardes, fokus en strategiee, wat dink soos 'n nommer twee om verseker die nommer een te wees. . ....

Texto completoFuel cell hybrid propulsion system is gaining momentum in today's automotive market and offers a sustainable solution for the world climate change in the transport sector. However, the durability and reliability of the power sources used in the hybrid system are the inevitable obstacles for its massive commercialization. To optimize and maximize the lifespan of the hybrid system, a prognostics and health management (PHM) approach is deployed to manage and mitigate the power source degradation behaviour and applied to a fuel cell hybrid electric vehicle.In this context, two main contributions are made. The first stage is to deploy a prognostics method that can be used in the hybrid system. Particle filtering, as a commonly used state estimation method, is adapted for prognostics purpose in this thesis. It is used to handle the imprecise and uncertain degradation data and estimate the remaining useful life. The method is validated by historical fuel cell and battery datasets and the results are evaluated by the designed prognostics metrics.Subsequently, a second stage on the health management aspect of PHM is proposed. As the split of demanded power in a hybrid system is managed by an energy management strategy (EMS), the orientation of this stage is to develop a health-conscious EMS in the context of PHM. A great quantity of researches on prognostics with finished experimental data have been found in the literature, while how to use the prognostics results to make corrective control actions is rarely discussed. To help against this vacancy in hybrid system applications, a prognostics-enabled decision-making process is designed. The performance is evaluated by quantifying the degradation and the lifetime of the system in a simulated environment and a discussion on prognostics occurrence is launched for further investigations on maintenance
