O presente trabalho de dissertação teve como objetivo a implementação de metodologias de Lean Management e avaliação do seu impacto no processo de Desenvolvimento de Produto. A abordagem utilizada consistiu em efetuar uma revisão da literatura e levantamento do Estado da Arte para obter a fundamentação teórica necessária à implementação de metodologias Lean. Prosseguiu com o levantamento da situação inicial da organização em estudo ao nível das atividades de desenvolvimento de produto, práticas de gestão documental e operacional e ainda de atividades de suporte através da realização de inquéritos e medições experimentais. Este conhecimento permitiu criar um modelo de referência para a implementação de Lean Management nesta área específica do desenvolvimento de produto. Após implementado, este modelo foi validado pela sua experimentação prática e recolha de indicadores. A implementação deste modelo de referência permitiu introduzir na Unidade de Desenvolvimento de Produto e Sistemas (DPS) da organização INEGI, as bases do pensamento Lean, contribuindo para a criação de um ambiente de Respeito pela Humanidade e de Melhoria Contínua. Neste ambiente foi possível obter ganhos qualitativos e quantitativos nas várias áreas em estudo, contribuindo de forma global para um aumento da eficiência e eficácia da DPS. Prevê-se que este aumento de eficiência represente um aumento da capacidade instalada na Organização, pela redução anual de 2290 horas de desperdício (6.5% da capacidade total da unidade) e pela redução significativa em custos operacionais. Algumas das implementações de melhoria propostas no decorrer deste trabalho, após verificado o seu sucesso, extravasaram a unidade em estudo e foram aplicadas transversalmente à da organização. Foram também obtidos ganhos qualitativos, tais como a normalização de práticas de gestão documental e a centralização e agilização de fluxos de informação. Isso permitiu um aumento de qualidade dos serviços prestados pela redução de correções e retrabalho. Adicionalmente, com o desenvolvimento de uma nova ferramenta que permite a monitorização do estado atual dos projetos a nível da sua percentagem de execução (cumprimento de objetivos), prazos e custos, bem como a estimação das datas de conclusão dos projetos possibilitando o replaneamento do projeto bem como a detecção atempada de desvios. A ferramenta permite também a criação de um histórico que identifica o esforço horário associado à realização das atividades/tarefas das várias áreas de Desenvolvimento de Produto e desta forma pode ser usada como suporte à orçamentação futura de atividades similares. No decorrer do projeto, foram também criados os mecanismos que permitem o cálculo de indicadores das competências técnicas e motivações intrínsecas individuais da equipa DPS. Estes indicadores podem ser usados na definição por parte dos gestores dos projetos da composição das equipas de trabalho, dos executantes de tarefas individuais do projeto e dos destinatários de ações de formação. Com esta informação é expectável que se consiga um maior aproveitamento do potencial humano e como consequência um aumento do desempenho e da satisfação pessoal dos recursos humanos da organização. Este caso de estudo veio demonstrar que o potencial de melhoria dos processos associados ao desenvolvimento de produto através de metodologias de Lean Management é muito significativo, e que estes resultam em ganhos visíveis para a organização bem como para os seus elementos individualmente.

Demand response concept has been gaining increasing importance while the success of several recent implementations makes this resource benefits unquestionable. This happens in a power systems operation environment that also considers an intensive use of distributed generation. However, more adequate approaches and models are needed in order to address the small size consumers and producers aggregation, while taking into account these resources goals. The present paper focuses on the demand response programs and distributed generation resources management by a Virtual Power Player that optimally aims to minimize its operation costs taking the consumption shifting constraints into account. The impact of the consumption shifting in the distributed generation resources schedule is also considered. The methodology is applied to three scenarios based on 218 consumers and 4 types of distributed generation, in a time frame of 96 periods.

Multi-agent approaches have been widely used to model complex systems of distributed nature with a large amount of interactions between the involved entities. Power systems are a reference case, mainly due to the increasing use of distributed energy sources, largely based on renewable sources, which have potentiated huge changes in the power systems’ sector. Dealing with such a large scale integration of intermittent generation sources led to the emergence of several new players, as well as the development of new paradigms, such as the microgrid concept, and the evolution of demand response programs, which potentiate the active participation of consumers. This paper presents a multi-agent based simulation platform which models a microgrid environment, considering several different types of simulated players. These players interact with real physical installations, creating a realistic simulation environment with results that can be observed directly in the reality. A case study is presented considering players’ responses to a demand response event, resulting in an intelligent increase of consumption in order to face the wind generation surplus.

Teaching and learning computer programming is as challenging as difficult. Assessing the work of students and providing individualised feedback to all is time-consuming and error prone for teachers and frequently involves a time delay. The existent tools and specifications prove to be insufficient in complex evaluation domains where there is a greater need to practice. At the same time Massive Open Online Courses (MOOC) are appearing revealing a new way of learning, more dynamic and more accessible. However this new paradigm raises serious questions regarding the monitoring of student progress and its timely feedback. This paper provides a conceptual design model for a computer programming learning environment. This environment uses the portal interface design model gathering information from a network of services such as repositories and program evaluators. The design model includes also the integration with learning management systems, a central piece in the MOOC realm, endowing the model with characteristics such as scalability, collaboration and interoperability. This model is not limited to the domain of computer programming and can be adapted to any complex area that requires systematic evaluation with immediate feedback.

Software development is a discipline that is almost as old as the history of computers. With the advent of the Internet and all of its related technologies, software development has been on high demand. But, and especially in SME (small and medium enterprise), this was not accompanied with a comparable effort to develop a set of sustainable and standardized activities of project management, which lead to increasing inefficiencies and costs. Given the actual economic situation, it makes sense to engage in an effort to reduce said inefficiencies and rising costs. For that end, this work will analyze the current state of software development’s project management processes on a Portuguese SME, along with its problems and inefficiencies in an effort to create a standardized model to manage software development, with special attention given to critical success factors in an agile software development environment, while using the best practices in process modeling. This work also aims to create guidelines to correctly integrate these changes in the existing IS structure of a company.

Teollisuuden palveluiden on huomattu olevan potentiaalinen lisätulojen lähde. Teollisuuden palveluiden dynaamisessa maailmassa räätälöinti ja kyky toimia nopeasti ovat kriittisiä asiakastyytyväisyyden ja kilpailuedun luomisprosessin osia. Toimitusketjussa käytetyn ajan lyhentämisellä voidaan saavuttaa sekä paremmat vasteajat, että alhaisemmat kokonaiskustannukset. Tutkielman tavoitteena on kuvata teollisuuden palveluiden dynaamista ympäristöä: asiakastarvetta, sekä mahdollisuuksia kaventaa pyydetyn ja saavutetun toimitusajan välistä eroa. Tämä toteutetaan pääosin strategisen toimitusajan hallinnan keinoin. Langattomien tietoliikenneverkkojen operaattorit haluavat vähentää ydinosaamiseensa kuulumatomiin toimintoihin, kuten ylläpitoon sitoutuneita pääomia. Tutkielman case osiossa varaosapalvelujen toimitusketjun kysyntä-, materiaali- ja informaatiovirtoja analysoidaan niin kvalitatiivisten haastatteluiden, sisäisten dokumenttien, kuin kvantitatiivisten tilastollisten menetelmienkin avulla. Löydöksiä peilataan vallitsevaa toimitusketjun ja ajanhallinnan paradigmaa vasten. Tulokset osoittavat, että vahvan palvelukulttuurin omaksuminen ja kokonaisvaltainen toimitusketjun tehokkuuden mittaaminen ovat ajanhallinnan lähtökohtia teollisuuden palveluissa.

Economists consider education as an investment in man. Education develops human resources necessary for the economic and political growth of any nation. Adam Smith stressed the importance of education and included the acquired and useful activities of all the inhabitants or members of society in his concept of fixed capital.‘ Karl Marx shared with Smith's view when he laid down that the function of education in a socialist society will be to overcome the alienation of the worker from the means of production; while developing the technical skill it will make him a complete man as well as a producer.2 Education is also considered as a powerful instrument for social change. By inculcating moral and spiritual values, it brings changes both in the individual and in the society. It aims at creating a social order founded on the values of freedom, social justice and equal opportunity.3 The objective of this exploratory study is to enquire into the existing system of managing higher educational institutions in Kerala, compare it with the accepted principles of management believed to be applicable to all organisations, and develop a model capable of introducing more effective management practices

Traffic Management system (TMS) comprises four major sub systems: The Network Database Management system for information to the passengers, Transit Facility Management System for service, planning, and scheduling vehicle and crews, Congestion Management System for traffic forecasting and planning, Safety Management System concerned with safety aspects of passengers and Environment. This work has opened a rather wide frame work of model structures for application on traffic. The facets of these theories are so wide that it seems impossible to present all necessary models in this work. However it could be deduced from the study that the best Traffic Management System is that whichis realistic in all aspects is easy to understand is easy to apply As it is practically difficult to device an ideal fool—proof model, the attempt here has been to make some progress-in that direction.
