Using system view to explain the development of mobile commerceChiang, Hsin-uan 13 September 2006 (has links)
Because of recently speeding up populization of the third generation mobile service, people raise the interest of researching mobile commerce again. This research will focus on studying the important factors of developing of mobile commerce, the relation of those factors, and the reason why mobile commerce could only success in Japen and Korea.
When 1999 people start to pay much attention to research the mobile commerce, most telecommunication providers in developing country have highly investment on mobile service. But only Japenese telecommunication providers gain success at that time.
During this period, academic circles and industrial circles constantly have research reports about mobile commerce. If we read these reports by their published years, we may find a revolving phenomenon: firms involving in developing m-comerce gained failure => related reports A published, and proposed some reasons of that failure and their suggestions => firms fixed their action by those reports, tried to develop m-cpmmerce again, but still faced failure => related reports A published, and proposed some reasons of that failure and their suggestions => firms fixed their action by those reports, tried to develop m-cpmmerce again, but still faced failure.
So this research tries to probe into the m-commerce by study the history of developing of m-commerce, including collecting the firms¡¦actions and perspectives and the representive literatures and discussions.
This research also believe that including this report, we haven¡¦t understood the m-commerce thoroughly. And the m-commerce is also changing by the increasing of bandwidth and the developing of new applicatons. And that the developing of m=-commerce needs the telecommunication firms, cellular phone firms and contant firms to collaboration to match the users¡¦pattern of each country.
Depanding on the three factors above, we believe that we should hold a systematic and overall point of view to understand the m-commerce, not simplely by several key success factors or key failure factors.
Depends on the case study in chapter 4, we have concluding a systematic analysis model. And we also compare the successful developing of Japenese and Korean m-commere. Finally we provide three dimensions of evaluatipn the developing project of m-commrce.

Taking a system view on customer value creationÅslund, Anna January 2016 (has links)
In Quality Management and Total Quality Management (TQM) customer focus and customer value creation is of importance and in organisations it is of high priority. Quality Management has had an internal focus when it comes to customer value creation but in the 21st century there is a need for an outward orientation and to go beyond the organisational borders. Also an increasing interest in social, societal and environmental issues can be seen, for instance by customers, organisations, quality awards and within the quality area. An area that considers these issues is the societal entrepreneurial sector. The purpose of this thesis has been to contribute to the knowledge and understanding about customer value creation from a system view. Additionally the purpose has been to contribute to the development of Quality Management. In order to fulfil the purpose, case studies have been performed. Cases within the societal entrepreneurial area have been studied and seven studies have been performed. Data have been collected through interviews, direct observations, participating observations and documents. All data have been collected empirically except in one study where a literature case study was used. The data were analysed through tools such as process mapping, attribute value mapping and rich picture process maps combined with analytical methods for case study research. The research journey started out from TQM and an internal perspective on customer value creation. As the studies went on, the system borders became wider as other areas important to customer value creation were identified: the customer value creating system went from an internal perspective to include an external perspective. The findings contribute to earlier research findings and give a comprehensive and simplified picture of a complex phenomenon and an opportunity to understand customer value creation from a system view. This thesis provides an overall map of the customer value creating system. Additionally it contributes to the development of Quality Management by expanding the view on customer value creation to include both an internal and an external oriented perspective. It also contributes by suggesting a fifth step in the quality management movement ´System Quality Management´ that considers social, societal and environmental factors through continuous improvement before, during and after value creation for customers. Further it contributes with a developed view on customers and the concept of customer value creation. The overall map provided includes three areas. Growth and development of societal entrepreneurial initiatives. The result shows important components for the creation of societal value based on the growth and development of societal entrepreneurial initiatives. Included are the processes, input and output important for societal value creation from unidentified needs until societal value can be delivered, management process and support process fields. Customer value creation in the customer sphere. Customer value has been found to be created beyond the use or purchase of a product or service. Value has also been found to be created for those that are not in direct contact with an initiative or its product or service. Customer value has been found to spread into society like ripples in a complex system of value creation. And Value Ripple Logic has been developed to describe this phenomenon. Management role in customer value creation. The management’s role in value creation has been found to be of importance in the creation of customer value in an indirect way through interaction with the surroundings and the initiative. Factors and behaviours have been found which are connected to the leaders and their essential management processes along with their input and output. The findings presented in this thesis have considerable potential for development. Further studies need to be done within the area concerning how customer value is created and to achieve an even more comprehensive picture of the customer value creating system and the suggested fifth step. The results presented in this thesis are a contribution to the knowledge and understanding about customer value creation from a system view and the development of the Quality Management. / <p>Vid tidpunkten för disputationen var följande delarbeten opublicerade: delarbete 6 accepterat för publicering och delarbete 7 inskickat.</p><p>At the time of the doctoral defence the following papers were unpublished: paper 6 accepted for publication and paper 7 submitted.</p>

Vers un dimensionnement optimal structure-commande de système multi-convertisseurs. : Application aux réseaux de tramways / Optimal design stucture-control of multi-converter systems. : Application to tramways networkVial, Rémi 26 January 2012 (has links)
La réduction de la facture énergétique et la réalisation des services systèmes au réseau électrique passent par l’intégration massive de convertisseurs d’électronique de puissance.On parle alors de systèmes multi-convertisseurs, de structures relativement complexes.Leur dimensionnement tant énergétique que dynamique peut ainsi s’avérer délicat e timpose actuellement au concepteur d’étudier chaque convertisseur indépendamment de son environnement. En négligeant ces interactions, cette méthode conduit souvent à un surdimensionnement, notamment des filtres d’entrée des convertisseurs, et ne prémunit pas le réseau d’éventuelles instabilités dynamiques.Les travaux de cette thèse proposent donc une méthode systémique pour le dimensionnement du réseau dans son ensemble. A partir d’un modèle construit automatiquement et intégrant l’ensemble des contraintes intervenant dans le dimensionnement énergétique,dynamique ou harmonique d’un système multi-convertisseurs, des outils de commande avancés permettent d’optimiser ce dimensionnement.Cette méthodologie de conception est alors appliquée à une nouvelle structure d’alimentation d’un réseau de tramways permettant un meilleur rendement sur cycle de fonctionnement complet. / Optimal design stucture-control of multi-converter systems. Application to a tramwaynetworkPower electronic is now widely used and allows better efficiency and performances. Wetalk about multi-converter to describe this complex system.Usually, to design this kind of system, engineers study each different part regardless ofpossible interactions. To avoid potential instability caused by this approximation, designershave to oversize input filter which lead to bulk solution.This thesis deals with system view use for design wide grid. A model is built automatically,and constraints are added, to take into account energy, dynamic and harmonicrequirements. Optimal and robust control are used to obtain the best design.This approach is used on a new power architecture for tramways, and allows a betterefficiency over operating cycle.

Specifika informačního managementu v síťové topologii / Specifika informačního managemntu v síťové topologiiBuzek, Jiří January 2011 (has links)
This work deals with programs designed to manage data networks and to their use in managerial practice. The purpose is to explain how these programs contribute to a systemic understanding of managed network and system thinking. All these methods are applied on example of two largest wireless ISP companies in South Bohemia. The dissertation explains the issue of making mental models of the managed network, which concerns specially managers of ISP companies. The work is not an administrator view at programs for network management, but rather a management view and instructions how to use these programs in management decisions to solve complex problems and future development of managed network.

Synchronization analysis and simulation of a standard IEEE 802.11g OFDM signalLowham, Keith D. 03 1900 (has links)
Approved for public release, distribution is unlimited / Synchronization of orthogonal frequency-division multiplexed (OFDM) signals is significantly more difficult than synchronization of a single-carrier system. The recently approved IEEE Standard 802.11g specifies a packet-based OFDM system that provides a basis for the discussion of OFDM synchronization in a packet-based environment. Algorithms that synchronize the receiver carrier demodulation frequency and phase, the data frame, the OFDM symbol timing, and the data symbol timing are discussed and analyzed in an AWGN channel. System View simulation is used to implement the frame and carrier frequency synchronization algorithms, where the performance of these algorithms is analyzed and they are shown to be useful detection algorithms for Standard 802.11g signal reception. / Lieutenant Commander, United States Navy

Storskalig förändring i komplexa system : Utforskande av en förändringsresa, från traditionell förvaltning till offensivkvalitetsutveckling i en kommunStenmark, Maria January 2017 (has links)
Utifrån att samhället genomgår stora förändringar och står inför nya utmaningar finns ett behov av förmåga att möta framtiden på ett nytt sätt. Det ställs nya krav på hur organisationer behöver jobba med utveckling då transformationen skapar nya beteenden hos oss människor. Offentlig sektor utmanas precis som andra myndigheter och företag. Ambitionen med examensarbetet har varit att utforska och beskriva en förändring i stor skala utifrån ett helhetsperspektiv. En kommunal verksamhet, som i två års tid arbetat med att åstadkomma en storskalig förändring, har varit föremål för denna fallstudie. Fallstudien har genomförts genom bland annat djupintervjuer, workshops och semistrukturerade intervjuer. Analysen har hämtat inspiration från Kuipers, Higgs, Kickert, Tummers, Grandia, och van der Voets (2013) rekommendationer till forskning om förändring i offentlig sektor. Rekommendationerna handlar om att inkludera förändringens kontext, innehåll, process, resultat och ledarskap. Den förändring studieobjektet genomgår inkluderar värderingar och kultur, arbetssätt och verktyg och drivs med målet att öka professionaliseringen, öka graden av personcentrering och för att etablera ett kontinuerligt lärande. Studiens resultat har visat att flera händelser och insatser är avgörande i en storskalig förändring mot offensiv kvalitetsutveckling som stämmer överens med tidigare forskning som rekommenderar att flera olika modeller och strategier bör användas beroende på situation. Studiens resultat visar också att framgång kan uppnås genom att bedriva flera förändringsprocesser parallellt och på kort tid. Tidigare forskning talar istället om att förändring behöver ta tid. Flera upplevda framgångsfaktorer har identifierats och de flesta framgångsfaktorerna är inte desamma som lyfts i den tidigare forskning som studerats. De framgångsfaktorer som är unika för fallstudien är: modigt ledarskap, systemtänkande, att utgå från kundens fokus istället för kunden i fokus, användning av teoretiska förändringsmodeller för att förankra förändringsarbetet, att driva flera förändringsprocesser parallellt i högt tempo och att inkludera organisationens kontext och historia. Studiens resultat har visat att fallorganiastionens förändringsprocess kan beskrivas i fjorton steg. Vissa av stegen återfinns i de teorier som studerats och vissa återfinns inte. Att stegen skiljer sig åt kan bero på att detaljnivån skiljer sig mellan studiens resultat, som mer specifik och de teoretiska förändrinsmodellerna, som är mer generella. Hörnstenarna i hörnstensmodellen har utifrån studiens resultat kunnat sekvenseras i en viss ordning och beskrivas med olika tyngdpunkt och betoning. Hörnstensmodellen skulle enligt studien kunna användas som en värderingsmodell i ett storskaligt förändringsarbete men också utifrån arbetssätt och verktyg. / Society is going through rapid change and social transformation is taking place. This is a result of mega trends such as individualization and digitalization. People are behaving in new ways and our future desires are harder than before to predict. New business models need to develop both within the private and the public sector. The ambition with this master thesis has been to take a whole system perspective and explore and describe a large scale transformation taking place within a large organization. A case study at the elderly care within public sector has been made to accomplish the ambition. The organization which has been studied has purposely been working with a large scale change program for two years with the determination to achieve a higher level of professionalism and customer orientation. The research design has included in-depth interviews, workshops, observations and semi-structured interviews. The analysis has been inspired from Kuipers, Higgs, Kickert, Tummers, Grandia, och van der Voets (2013) recommendations to include context, content, process, result and leadership in change-oriented research within the public sector. The results from the case study shows that many different efforts and activites are crucial to achieve a large scale change implementing TQM. This finding is in line with previuos reasearch. Another finding from the case study, that differs from previous research, is many simultaneously initiatives and efforts managed in a relatively short time seems to be a success factor for large scale change in large organizations and complex systems. Previous research says in contradiction that change needs time. Many more perceived success factors was identified. Some of them are slightly similar to previous research but many of the findings are not found in theories studied. Critical success factors uniqe for this case study are: courageous leadership, systems thinking, a perspective taken from the customers point of view instead of a customer oriented perspective, the practical use of theorethical change models, many change projects simultaneously driven in a fast speed and the organisations history of change projects included as well as the organisations unique context. The findings from the case study also shows a change process that can be described in fourteen steps. Some of these steps are found in the change management theories and others are not. The descpription of the steps from this case study are somewhat more detailed and related to the context whereas the theoretical change models have a more general characteristic. The change process was also viewed through the TQM-model named The corner stone model, and this showed that the cornerstones can be sequenced in a certain order based on the results of the study. The stones can also be described with different highlighting due to the change context. Different emphasis and content among the cornerstones could also been seen. The corner stone model could, accoring to this case study, could therfore be used as a value model in large scale change, but also as a change model for working ways and tools. / <p>2017-06-28</p>
