Customer retention is an important issue for any business, especially in mature markets such as the UK mobile market where new customers can only be acquired from competitors. Different methods and techniques have been used to investigate customer retention including statistical methods and data mining. However, due to the increasing complexity of the mobile market, the effectiveness of these techniques is questionable. This study proposes Agent-Based Modelling and Simulation (ABMS) as a novel approach to investigate customer retention. ABMS is an emerging means of simulating behaviour and examining behavioural consequences. In outline, agents represent customers and agent relationships represent processes of agent interaction. This study follows the design science paradigm to build and evaluate a generic, reusable, agent-based (CubSim) model to examine the factors affecting customer retention based on data extracted from a UK mobile operator. Based on these data, two data mining models are built to gain a better understanding of the problem domain and to identify the main limitations of data mining. This is followed by two interrelated development cycles: (1) Build the CubSim model, starting with modelling customer interaction with the market, including interaction with the service provider and other competing operators in the market; and (2) Extend the CubSim model by incorporating interaction among customers. The key contribution of this study lies in using ABMS to identify and model the key factors that affect customer retention simultaneously and jointly. In this manner, the CubSim model is better suited to account for the dynamics of customer churn behaviour in the UK mobile market than all other existing models. Another important contribution of this study is that it provides an empirical, actionable insight on customer retention. In particular, and most interestingly, the experimental results show that applying a mixed customer retention strategy targeting both high value customers and customers with a large personal network outperforms the traditional customer retention strategies, which focuses only on the customer‘s value.

Em um mercado cada vez mais competitivo como o de telefonia celular pós-paga as organizações modernas estão em constante busca por lucratividade e crescimento contínuo. Nesse sentido, a retenção dos clientes atuais e a busca por fidelidade tornam-se pauta de discussões acadêmicas e empresariais. No estudo dessa fidelidade, a academia se divide em duas correntes: a primeira defensora da satisfação como antecessor necessário da lealdade e a segunda, da lealdade como elemento independente da satisfação. O presente trabalho buscou aclarar esses conceitos, com definição dos termos e principais pensamentos. Por meio de pesquisa realizada junto aos consumidores de telefonia celular pós-paga, verificou-se a avaliação desse público quanto à satisfação, vínculo, imagem da operadora, bem como a manutenção ou não desse relacionamento. / In a competitive market as the mobile post paid, the modern companies are in a constant search for profitability and growth. In that sense, the consumer retention and the study of loyalty become topics into the agendas of the academics and the business discussions. Through the study of the consumer´s loyalty the academics are divided in two different ideas: the first one defends the satisfaction as a prior to the loyalty and, for the defenders of the second idea, the loyalty is an independent element from the satisfaction. The current paper tried to dig into these concepts, with the definition of the main terms and thoughts. By researches made with the mobile post paid consumers, the evaluation of topics such as satisfaction, link, image and the capacity to keep the relationship.

The advance of mobile phone devices and wireless communication have dramatically change the way individuals do for their personal lives and businesses. Nowadays, people can not only talk with their peers located at different places, they can also get the desired information ubiquitously. Business strategies that are based on simple mobile phones have to be adapted to a complex mobile business ecosystem. The mobile phone market in Guatemala has almost saturated, and the mobile operators have to come up with creative ideas to increase their revenues. This thesis explores what the user¡¦s intentions toward mobile services in Guatemala. Understanding users¡¦ intension will allow entrepreneurs to create new business strategies that would fill an existing void that exists on the Guatemalan mobile market.

This work aims to prepare the analysis puts current trends in the mobile market, and these results are then used to evaluate the current position of Vodafone Czech Republic and its marketing communications to mobile communications market in the Czech Republic. The analytical part of the work focuses on the local telecommunications market, regulatory environment, and marketing communications company described. Based on these findings are then also defined current trends in the mobile communications market and they then derive predictions of the future development of the entire market. Given the specific nature of this market, the individual's internal analysis based on information obtained directly from the surveyed companies, which for this work of great benefit as set out conclusions are backed by real market data. The work also draws on research methods conducted among customers of mobile operators, but their aim was to determine customer attitudes to new technologies or brand awareness operator or its marketing communications.

This work deals with the development of cross-platform mobile applications and compares cross-platform development frameworks. First the mobile devices market is defined and its dominant platforms are described. The main objective is to compare the frameworks with defined criteria. The theoretical part analyzes the mobile market and defines the different types of mobile devices. Further, describes the various mobile platforms, including its architecture and de-velopment environment. Subsequently, the approaches to cross-platform development are described with their individual frameworks. In the practical part the selected frameworks are compared to defined criteria and subse-quently evaluated.
