Inovação auxiliada por computador (CAI): uma análise bibliométrica de artigos publicados entre 2004 e 2013

In recent decades, innovation has come to be seen as a crucial factor for the competitiveness of organizations. From a process little orderly, innovation has come to be systematized, with the establishment of tools, methodologies and theories. A variety of computer programs have been created to support innovation, giving rise to a new category of tools, which is being called Computer Aided Innovation (CAI). This exploratory research seeks to understand more precisely the concept of CAI, as well as identify key publications, authors, institutions and regions in which it has been developed, besides seeking to identify gaps and trends of the topics covered in the area. Given the purpose of the research, it was decided to use bibliometrics, which allows obtaining the information indicated from the analysis of the main databases related to CAI. The research consists of 217 articles, published between 2004-2013. The methodological procedures to develop the research involved the following steps: a) raise the state of the art regarding the Computed Aided Innovation; b) Survey and data collection of scientific papers on CAI; c) categorization and bibliometric analysis and d) classify and analyze the topics covered. The results obtained through the bibliometric analysis revealed that there were 378 different authors, and authors have increased an average of 34.7% from 2004 to 2013. When checking the adhesion of the Lotka´s law to the field of CAI, It was observed that 72.8% of the authors had only one publication, 15% more than proposed by Lotka, than the area of CAI does not adjust to this law. The most productive authors were Runhua Tan (complete count) and Noel Leon (direct counting). The most cited author was Gaetano Cascini. The most productive country in the world is China, with 41% of publications, as well as having the largest number of researchers (42% of total) and the largest number of institutions. However, the country with the greatest relevance is France, because the French articles had 30.4% of the citations. The more productive institution is Hebei Universi ty of Technology, China, with 16% of the articles. The institution most frequently cited is INSA Strasbourg, France. By analyzing the topics covered, it was realized that the "Idea Management" category is more developed and the category "Management Patent" is the one with the least amount of work. It is considered that this research has contributed to give visibility to researchers, institutions and countries that have contributed to the development of CAI, besides recognizing the theoretical core that serves as the foundation of knowledge of the area. The theme CAI is extremely important for the improvement of the innovation process, enabling to innovate more efficiently and effectively.Nas últimas décadas, a inovação passou a ser vista como um fator crucial para a competitividade das organizações. De um processo pouco ordenado, a inovação tem passado a ser sistematizada, com o estabelecimento de ferramentas, metodologias e teorias. Uma variedade de programas computacionais têm sido criadas para apoiar a inovação, dando origem a uma nova categoria de ferramentas, que vem sendo denominada Computer Aided Innovation (CAI), ou Inovação Auxiliada por Computador. Esta pesquisa, de característica exploratória, busca compreender com maior exatidão o conceito de CAI, bem como identificar as principais publicações, autores, instituições e regiões nas quais o assunto tem sido desenvolvido, além de buscar identificar as lacunas e tendências dos temas abordados na área. Dada a finalidade da pesquisa, decidiu-se pelo uso da bibliometria e da análise de conteúdo para alcançar os objetivos estabelecidos. O universo da pesquisa constitui -se de 217 artigos, publicados no período de 2004 a 2013. Os procedimentos metodológicos para desenvolver a pesquisa envolveram os seguintes passos: a) levantar o estado da arte no que se refere a Inovação Auxiliada por Computador; b) levantar e coletar os dados dos artigos científicos em CAI; c) categorizar e fazer análise bibliométrica e d) classificar e analisar os temas abordados. Os resultados obtidos, por meio da análise bibliométrica, revelaram que houve 378 autores diferentes, e que a média de autores aumentou em 30,4% de 2004 a 2013. Ao verificar a aderência da lei de Lotka à área de CAI, observou-se que 72,8% dos autores tiveram apenas uma publicação, sendo 15% a mais do que o proposto por Lotka, ou seja, a área de CAI não se ajusta a esta lei. Os autores mais produtivos foram Runhua Tan (contagem completa) e Noel León (contagem direta). O autor mais citado foi Gaetano Cascini. O país mais produtivo do mundo é a China, com 41% das publicações, além de possuir o maior número de pesquisadores (42% do total) e o maior número de instituições. No entanto, o país com a maior relevância é a França, pois os artigos franceses tiveram 30,4% das citações. A instituição mais produtiva é Hebei University of Technology da China, com 16% dos artigos. A instituição mais citada é INSA Strasbourg, França. Ao analisar os temas abordados, percebeu-se que a categoria “Gestão de Ideias” é mais desenvolvida e a categoria “Gestão de Patentes” é a que possui a menor quantidade de trabalhos. Considera-se que esta pesquisa contribuiu para dar visibilidade aos pesquisadores, instituições e países que tem contribuído para o desenvolvimento do CAI, além de reconhecer o núcleo teórico que serve de alicerce do conhecimento da área. O tema CAI é de suma importância para a melhoria do processo de inovação, possibilitando inovar com mais eficiência e eficácia

Evolution of component and aspect-based product line architectures

Orientador: Cecília Mary Fischer RubiraTese (doutorado) ¿ Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: Arquiteturas de linhas de produtos são essenciais para facilitar a evolução das linhas, pois ajudam a lidar com sua complexidade, abstraindo seus detalhes de implementação. A variabilidade arquitetural difere arquiteturas de linhas de produtos de arquiteturas de sistemas únicos. Ela reflete a existência de alternativas de projeto arquitetural e é expressa por meio de um conjunto de pontos de variação e variantes arquiteturais. A variabilidade arquitetural pode dificultar a evolução de arquiteturas de linhas produtos, pois a implementação da variabilidade software pode aumentar a complexidade da arquitetura com a possível adição de elementos e dependências extras. A variabilidade de linhas de produtos é usualmente capturada modelo de características e implementado pela arquitetura de linha de produtos. Entretanto, a implementação de características, pontos de variação e variantes podem estar espalhados por diversos elementos arquiteturais, o que dificulta a sua evolução. Em geral, cenários de evolução de linhas de produto envolvem adição e/ou remoção de características, mudança de uma característica obrigatória para opcional, entre outros. Quando cenários de evolução afetam características cujas implementações estão espalhadas na arquitetura, eles podem causar impacto de mudança em vários elementos arquiteturais. Estudos recentes exploram o uso de aspectos para modularizar a implementação de características em arquiteturas de linhas de produtos. Aspectos são usados para modularizar interesses transversais que, no contexto de linhas de produtos, são interesses que afetam diversas características. Contudo, esses estudos não consideram (i) arquiteturas componentizadas com interfaces explícitas e (ii) o uso integrado de componentes e aspectos para modularizar a implementação da variabilidade arquitetural. Idealmente aspectos devem ser modelados o mais cedo possível, de preferência, junto com o modelo de características para possibilitar a criação de arquiteturas bem estruturadas com aspectos. Todavia, não existem modelos que integrem o modelo de características e aspectos, nem métodos que consideram aspectos para gerar arquiteturas de linhas produtos a partir do modelo de características. A solução proposta nesta tese envolve inicialmente um estudo comparativo para mostrar a facilidade de evolução de arquiteturas de linhas de produtos propiciada pelo uso integrado de componentes e aspectos. Em seguida, é proposta uma visão estendida do modelo de características que permite representar características transversais. Essa visão, chamada de visão de características orientada a aspectos, é usada para criar arquiteturas de linhas de produtos orientadas a aspectos. Além disso, um modelo arquitetural de componentes é estendido para integrar aspectos para modularizar a variabilidade arquitetural. Por fim, o método FArM, que provê o mapeamento de modelo de características para modelos de arquitetura de linha de produtos, é estendido para considerar características transversais. Foram conduzidos dois estudos empíricos: um para avaliar se o uso integrado de componentes e aspectos facilita ou não a evolução de arquiteturas de linhas de produtos. O outro estudo empírico avalia a modelagem de características transversais e a extensão do método FArM propostos para projetar arquiteturas de linhas de produtos que sejam fáceis de evoluir. Os dois estudos apresentaram resultados promissores indicando que a solução proposta nesta tese facilita a evolução de arquiteturas de linhas de produtosAbstract: Product line architectures are essential to facilitate the evolution of product lines, as they handle their complexity by abstracting implementation details. Architectural variability is what differs product line architectures from single system architectures. It reflects the existence of alternative design options and it is expressed by a set of architectural variation points and variants. Architectural variability can hinder product line architecture evolution because the implementation of software variability can increase architecture complexity by possibly adding extra elements and dependencies. Product line variability is usually captured in the feature model and it is implemented by product line architectures. However, the implementation of features, variation points, and variants may be scattered over architectural elements, which can hinder its evolution. In general, product line evolution scenarios involve feature addition/removal, changing a mandatory feature to an optional feature, and so forth. When evolution scenarios affect features whose implementations are scattered over architecture, they can cause a great change impact on several architectural elements. Recent studies have explored the use of aspects to modularize feature implementation in product line architectures. Aspects can modularize crosscutting concerns, which, in the context of product lines, are concerns that affect several features. Nevertheless, these studies do not consider (i) componentized architectures with explicit interfaces, and (ii) the integration of aspects and components to modularize the implementation of architectural variability. Ideally, aspects should be modeled as soon as possible, preferably, together with the feature model in order to enable the design of well structured product line architectures with aspects. However, there are neither models which integrate features and aspects, nor methods that considers aspects to design product line architectures from the feature model. The solution proposed in this thesis involves a comparative study that presents the support for product line architecture evolution provided by the integration of components and aspects. Then, it is proposed an extended view of the feature model which enables to represent crosscutting features. This view, called aspect-oriented feature view, is used to design product line architectures with aspects. Lastly, the FArM method, which provides guidelines to map from the feature model to the product line architecture model, is extended to consider crosscutting features. Two empirical studies were conducted: one to assess whether the integration of components and aspects facilitates product line architecture evolution. The other empirical study evaluates whether the crosscutting feature modeling and the FArM method extension proposed supports the design of evolvable product line architectures. Both studies presented promising results which indicate that the solution proposed in this thesis facilitates product line architecture evolutionDoutoradoCiência da ComputaçãoDoutor em Ciência da Computaçã

An approach based on software product lines using components and aspects in Android platform

Orientador: Cecília Mary Fischer RubiraDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: O número de dispositivos móveis utilizando a plataforma Android cresceu dramaticamente nos últimos anos, contribuindo para uma explosão no número de aplicações. Hoje, são mais de um milhão de aplicativos disponíveis para download. Essas aplicações estão crescendo em número, tamanho e estão se tornando cada vez mais complexas, requisitando técnicas sofisticadas de engenharia de software, como por exemplo, programação orientada a aspectos e o desenvolvimento baseado em componentes, que foram amplamente explorados em plataformas desktop mas não foram muito investigadas na plataforma Android. Na literatura, poucos estudos foram feitos para mostrar sua viabilidade em cenários reais de implantação. Nesta plataforma, existem limitações de memória e poder de processamento que podem limitar o uso dessas técnicas sofisticadas. Este trabalho explora a plataforma Android em uma abordagem que utiliza essas técnicas sofisticadas de engenharia de software para modularizar interesses transversais para construção de Linhas de Produtos de Software (LPS) e a aplicação desta abordagem em estudo de caso reais. No primeiro estudo de caso, a abordagem é avaliada em relação à quantidade de memória e desempenho, e posteriormente, comparada em relação a abordagens tradicionais como o desenvolvimento baseado em componentes e o desenvolvimento orientado a objetos. No segundo estudo de caso, a abordagem é verificada em relação ao atendimento de requisitos não funcionais de tolerância a falhas no domínio de coleta de dados em campo. Os principais artefatos desse segundo estudo de caso são uma arquitetura e uma aplicação para este domínioAbstract: The number of smartphones running on Android platform increased dramatically in the past few years, contributing to an explosion in the number of applications. Today, there are more than a million available for download. These applications are increasing in the number, size and becoming more complex requiring sophisticated software engineering techniques such as Aspect-Oriented Programming (AOP) and Component-Based Development (CBD) which are highly exploited in desktop environments but have not been much investigated in this platform. In the literature, few studies have been conducted in order to show their feasibility in real industry deployment scenarios. In Android platform, there are limitations in memory and processing power that can limit the use of these software engineering techniques. This work explores Android platform in an approach that uses these sophisticated techniques to modularize crosscutting concerns to build Software Product Lines (SPLs) and its application in real case studies. In the first case study, the approach is evaluated in terms of memory allocation and performance; later, it is compared to traditional approaches such as component-based development and object-oriented programming. In the second case study, the approach is verified in terms of fault-tolerant non-functional requirements suitability in the data collection domain. The main artifacts of this second case study include an architecture and an application for data collection domainMestradoCiência da ComputaçãoMestre em Ciência da Computação131824/2013-9CNP

A Digital Game Maturity Model

Game development is an interdisciplinary concept that embraces artistic, software engineering, management, and business disciplines. Game development is considered as one of the most complex tasks in software engineering. Hence, for successful development of good-quality games, the game developers must consider and explore all related dimensions as well as discussing them with the stakeholders involved. This research facilitates a better understanding of important dimensions of digital game development methodology. The increased popularity of digital games, the challenges faced by game development organizations in developing quality games, and severe competition in the digital game industry demand a game development process maturity assessment. Consequently, this study presents a Digital Game Maturity Model to evaluate the current development methodology in an organization. The objective is first to identify key factors in the game development process, then to classify these factors into target groups, and eventually to use this grouping as a theoretical basis for proposing a maturity model for digital game development. In doing so, the research focuses on three major stakeholders in game development: developers, consumers, and business management. The framework of the proposed model consists of assessment questionnaires made up of key identified factors from three empirical studies, a performance scale, and a rating method. The main goal of the questionnaires is to collect information about current processes and practices. This research contributes towards formulating a comprehensive and unified strategy for game development process maturity assessment. The proposed model was evaluated with two case studies from the digital game industry
