Description:
Emerging systems like wearable device environments, mobile apps, and sensors networks have been transforming how organizations and communities carry out their business processes and decision-making. These systems, when designed as constituent systems within a System-of-Systems (SoS), present new and unique features that cannot be provided by any individual system separately. This may expand the comprehension of variables and thus enhance business analysis. However, the heterogeneity and managerial independence of the constituent systems pose challenges when modeling, designing and developing a SoS. They have their own prerequisites, architectures, and technologies used that might not be flexible to changes or, even more, may diverge to the overall SoS. Moreover, a SoS often provides information and/or features that do not match target-users’ needs, which in turn could hamper business tasks and decisions. Therefore, this project proposal will develop a methodology that designs SoSs more aligned with business processes by understanding the bridging elements among them and how they can be handled. This methodology will be built on two elements: (a) an architectural design process that guides the design of a SoS architecture and (b) a model that handles emerging behavior of SoS by matching its functionalities to characteristics of business activities. These elements will be established and evaluated in interactive design and analysis cycles, taking as a case study the context of monitoring environmental variables within a Brazilian early-warning center. Results expected from this project include both the methodology’s elements and lessons earned from their employment in both experimental evaluations and a real-world case study. Together, these contributions comprise valuable contributions to practice and research on the design, development, and evaluation of SoS more aligned with organizations’ processes and decisions.

Description:
The objective of the project is the development and application of heuristic methods and decomposition techniques, based on the POPMUSIC method. The basic ideas of POPMUSIC can be summarized in the following four steps: (i) create an initial solution; (ii) decompose the initial solution into “parts”; (iii) optimize a portion of the initial solution (made up of several “parts”); (iv) repeat the previous step until the optimized portions cover the entire solution. The most complex part of the method is to create the initial solution. This is because it is very difficult to create a decent solution with less complexity than O (n^2), where n is the size of the problem. Considering “large” instances (>> 10^4), this step is impractical. On the other hand, step (iii) can be performed in “almost linear” time, as shown in works in the literature for the problem of cartographic labeling and for the problem of location and routing. In fact, with the POPMUSIC method, the improvement in the quality of a given solution, obtained through a basic optimization method, such as an exact method, for example, is not what most contributes to the complexity of the algorithm.

Description:
In the last few decades, there has been an exponential growth in the advancement of the storage and processing capacity of the available hardware, so that the infrastructure of organizations has evolved substantially. Above all, in the 2010’s, taking advantage of this scenario of greater abundance of data, there were solid advances in the results obtained by Machine Learning models, which is a subfield of Artificial Intelligence. Such results belong to tasks in different areas, ranging from Computer Vision to Natural Language Processing, and are mainly due to new algorithms and architectures of Artificial Neural Networks, which received the nickname Deep Learning. This project aims to study and apply some of these models to problems in different fields.

Descrição:
A prefeitura da cidade do Rio de Janeiro, através da IPLAN, criou recentemente um serviço inspirado no Uber, para a rede de táxis oficiais cadastrados, chamado Taxi.Rio. Tal serviço está no ar desde novembro de 2017. O sistema registra dados de todas as chamadas e corridas ocorridas e canceladas. A partir da iniciativa de parceria institucional firmada entre a prefeitura do Rio de Janeiro e a UNIRIO, esses dados de mobilidade originados das corridas estarão disponíveis para análises. Estamos engajados em vários estudos com tais dados. O projeto aqui descrito visa a desenvolver um estudo do comportamento de passageiros e motoristas na aceitação e no cancelamento de chamadas de corridas. De acordo com dados preliminares do banco de dados da Taxi.Rio, 46% das corridas são canceladas. Entender por que tantas corridas são canceladas é objetivo importante por diversas razões. A identificação das causas principais dos cancelamentos é condição fundamental para a formulação de políticas públicas que lidem com tal problema. Do ponto de vista econômico, o excesso de cancelamentos prejudica o já congestionado trânsito, com reflexos negativos sobre a mobilidade urbana na cidade do Rio de Janeiro. Há também efeitos negativos sobre o meio-ambiente, por conta dos deslocamentos inúteis das viaturas (quantificar tal efeito é per se uma meta importante). À luz do que foi observado nos EUA, com dados do Uber mencionados acima, pretende-se investigar que fatores impactam a produtividade do serviço público de mobilidade Taxi.Rio que justifiquem um índice de cancelamento tão alto e, mais especificamente, analisar características que influenciam cancelamentos de chamadas de corridas, tanto por motoristas quanto por passageiros. Consideraremos fatores objetivos como por exemplo o tempo de demora do serviço, mas também fatores subjetivos como caraterísticas extraídas das imagens dos motoristas. Também estudaremos os fatores determinantes da avaliação, tanto de motoristas, quanto de passageiros. Por fim, a partir da descoberta de padrões nos cancelamentos e nas execuções das corridas, almejamos desenvolver um sistema de recomendações de corridas que minimizem o número de cancelamento, com isso melhorando o serviço prestado à população. Também esperamos poder estimar o crescimento do serviço compartilhado do Taxi.Rio.

Description:
The globalization of the software industry has expanded business opportunities for organizations that hire and offer IT products and services. In this context, the choice of which technology or application to acquire, develop, replace or discontinue requires an assessment of which options are best suited to the needs of stakeholders and to budget and IT architecture constraints. However, in recent years, the increasing dependence on networks of suppliers and external developers to achieve organizational goals and address the diverse demands has made maintenance decisions for these architectures more complex. This is due to the fact that this set of technologies and applications, which can be extended and/or integrated, forms a central technological platform that brings together a community of suppliers, external developers and users, producing networks called Software Ecosystems (ECOS). Due to the effects of the dynamic nature of an ecosystem, IT managers and architects need to deal with several requirements that must be settled in the maintenance decisions for the architectures of these platforms. Given their recent propositions, it is unknown which pieces of data from these networks and how their joint analysis will support the decisions of such professionals. More specifically, it is not known what requirements should be coordinated in decisions to maintain the architecture of an ECOS platform and how to support organizations that seek to qualify activities of this nature in software development. The research project presented aims to fill this gap in the literature, and its objective is to develop an approach to requirements coordination, aiming to optimize maintenance of IT architectures in the ECOS scenario.

Descrição:
As cidades inteligentes envolvem a integração de serviços e aplicações em uma infraestrutura tecnológica unificada com o objetivo de melhorar a qualidade dos serviços de uma cidade. O desenvolvimento dessas aplicações não é trivial, pois é necessário levar em consideração diversas características inerentes do contexto de cidades inteligentes, como aspectos de interoperabilidade, gerenciamento de um grande volume de dados, aspectos sociais de interação dos usuários com as aplicações e entre outros. Para apoiar o desenvolvimento das aplicações no contexto de cidades inteligentes, pode-se fazer uso de técnicas de desenvolvimento definidas na Engenharia de Software (ES) que buscam prover meios para apoiar diversas atividades do desenvolvimento de sistemas. Essas técnicas podem estar relacionadas com o processo de desenvolvimento de software, elicitação de requisitos e modelagem das aplicações. Desta forma, as técnicas buscam garantir que os sistemas sejam desenvolvidos corretamente e com a qualidade esperada. Executar essas técnicas para o desenvolvimento de aplicações no contexto de Cidades Inteligentes ainda é um desafio. Desta forma, o objetivo deste projeto é o desenvolvimento de técnicas de desenvolvimento de software no contexto de Cidades Inteligentes, tais como: (i) definição de processo de software aderente às características de aplicações para Cidades Inteligentes; (ii) criação de modelagens de software específicas para este contexto; e, (iii) técnica de avaliação da qualidade das aplicações deste contexto. Espera-se que os resultados a serem obtidos com este projeto contribuam com o avanço da pesquisa científica em Engenharia de Software, além de disponibilizar novas técnicas para serem utilizadas pela Indústria de Software.

Descrição:
Buscando alcançar seus objetivos de negócio, as organizações estabelecem estratégias envolvendo à produção de software e à prestação de serviços de TI interna ou externamente. Organizações são entidades dinâmicas e, como tal, seus objetivos de negócio e estratégias sofrem alterações ao longo do tempo, motivadas por fatores internos (por exemplo, resultados obtidos) e externos (por exemplo, novas leis ou necessidades estabelecidas pelo mercado). O uso de indicadores apoia a monitoração e controle de estratégias e do alcance a objetivos de negócio, uma vez que fornece informações sobre os resultados obtidos e auxilia na identificação de ações corretivas necessárias quando eles não são satisfatórios. Porém, definir estratégias e indicadores para monitorá-los não é uma tarefa trivial. Além disso, é preciso lidar com as alterações necessárias ao longo do tempo. Nesse sentido, um método de apoio à definição de estratégias e indicadores, bem como monitoração e controle das estratégias e destas em relação aos objetivos de negócio pode contribuir para o fornecimento de software e serviços de TI alinhados aos objetivos de negócio da organização e, dessa forma, auxiliar no seu alcance. Este projeto de pesquisa tem por objetivo criar um método de apoio às organizações de software e prestadoras de outros serviços de TI na definição e no monitoramento dos objetivos e estratégias para atingi-los, de forma a manter o alinhamento com os objetivos de negócio. Além disso, prevê-se a definição de um padrão para aplicação da abordagem GQM+Strategies para definição de estratégias.

Description:
This research project addresses software degradation caused by unwanted behavior by developers and strategies to deal with that behavior. These strategies will possibly be inspired by game theory concepts. We assume that software degradation can be measured by the number and types of kludges made by software developers in the code. A kludge is code that: (i) partially corrects a bug or partially implements a feature; and (ii) the developer knows that the code is only a partial solution, with a high probability. This project aims to study how software projects evolve in terms of number and types of kludges. We are trying to identify kludges by looking at alerts generated by the PMD source code analyzer. PMD is a static source code analyzer commonly used to find possible programming flaws. The steps in this project involve: (i) confirming the assumption that the frequency of PMD alerts is an accurate measure of kludge prevalence; (ii) confirm the assumption that kludges hinder software development; (iii) confirm the assumption that there is a game in which, in the Nash balance, a developer chooses a strategy in which they obtain personal benefits while causing damage to the project, making kludges; (iv) if all of these assumptions are true, propose a strategy to change the environment so that developers choose not to make so many kludges; (v) implement this mechanism by creating a plug-in for a prominent CI tool, such as Travis, Jenkins or GitLab.

Description:
Computationally difficult problems with enormous practical importance appear in the most diverse areas, such as computer science, operational research, bioinformatics, engineering, transport, networks, logistics, business, etc. Despite technological advances, efficiently finding optimal solutions for important problems of this nature is still a challenge, often unfeasible due to time constraints. An alternative to efficiently obtain approximate (not necessarily optimal) quality solutions is the use of heuristics based on metaheuristics (intelligent heuristics). Metaheuristics are general procedures that generate families of algorithms that must be instantiated for each specific problem. They are based, above all, on the combination of constructive algorithms with local search techniques that enable us to escape from greater locations that trap simpler heuristics. Among the main metaheuristics, it is possible to mention: simulated annealing (SA), tabu search, genetic algorithms (GA), greedy randomized adaptive search procedure (GRASP), variable neighborhood search (VNS), iterated local search (ILS), large neighborhood search (LNS), ant colony, among others. Another alternative, which has been explored recently, are hybrid methods that combine heuristics and mathematical programming, known as matheuristics. For many computationally difficult problems, in a wide variety of areas, heuristic methods are considered to be state of the art methods.
The most general objective of the research is the development of heuristics and hybrid algorithms to solve problems of high computational complexity (NP-Difficult). For this, it is necessary to carry out a theoretical research comprising the in-depth study of several metaheuristics and several NP-difficult problems, or models of entire linear programming; and an experimental research: analyzing the data produced by the tests, both with regard to the quality of the solutions, specificity of the instances, and relative times.

Description:
Online social media is becoming a central research topic in several areas of academic research. One of the objectives of this project is to explore the most popular online social networks, such as Facebook, Twitter, Linkedin and Youtube, in order to try to understand how people, that is, users of these networks, behave and influence specific temporal phenomena of any nature, for example: spread of an epidemic (public health), current ideological propensity (politics), target audience of a certain product (commercial), among others. Social Network Analysis (SNA) is an approach that provides a set of collection and analysis methods strongly based on Graph Theory. The first challenge is to identify what type of network will be needed for a given study. Then, it is necessary to choose what will be considered actors (nodes) and relationships (connections). The collected data will serve as the basis for generating the graph underlying the network, when the analysis itself begins. This analysis depends on measurements obtained from the graph generated. In general, these measures can be classified into two types: metrics of a node and metrics of the network (graph). Among the main metrics for the analysis of a node are: degree of the node, degree of intermediation, degree of proximity, eigenvector and page rank. As the main network metrics, we can mention: density, clustering coefficient, centralization, components, diameter and modularity. Finally, it is necessary to interpret these metrics. In addition to the objective previously described, another point of interest is to investigate and propose new metrics and algorithms directed to SNA.

Description:
Organizations are increasingly investing in the management of their processes in order to increase their productivity. Business process models have been used to expose information on how the business works, in order to contribute with discussions and speed up changes. In this sense, they also become instruments of communication and common understanding of the organization’s members about its operation. On the other hand, organizations have been subject to greater demands for the ability to provide transparency about their operation, performance and results. At this point, process models can serve as instruments for representation of the services provided by these organizations. However, process models, in general, contain information about their operation that do not represent important elements for the customer, for example: quality criteria for the service provision, response times, ways of delivering the service value, elements that are part of the Service Level Agreements that every service provision organization must share with its client. This project seeks to define and implement ways of representing information about Service Level Agreements in business process models so that they can be better understood by customers, demonstrating greater value delivery by organizations. This representation, at first, will occur through the enrichment of the semantics of the elements used to represent process models.

Description:
Software-defined networks are already providing network administrators with greater control power, but generating many OpenFlow rules simultaneously is still hard work. It is necessary to preview each type of traffic, or at least implement the treatment to be performed in the control layer for still unknown packages. This research project is aimed at the creation of a set of resources that provide the administrator with a traffic orchestration architecture with a friendly configuration language, to define how traffic should be routed within an OpenFlow network domain. This language will be used for the high-level definition of network policies, which in its turn will be interpreted and will generate a set of OpenFlow rules that have a higher priority than those created by the IP routing platform in use.

Contents:
Genetic Programming is a type of heuristic search developed with the intention of generating programs automatically to perform certain tasks. Genetic Programming uses evolutionary operators, similar to those used in genetic algorithms, to evolve a set of programs over several generations. Although the scope of this technique in generating programs automatically is still limited, it has been used for other purposes. In this research project, we propose the use of genetic programming to define a software design theory in the form of a set of equations that relate structural design metrics. Our expectation is that the optimization of the software structure according to these equations reflects the organization of the source code of systems considered successful according to criteria oriented to the technical and economic evaluation of the software maintenance capacity.

An increasingly dynamic, unpredictable and challenging environment means that organizations need to cross their borders and establish partnerships with other organizations to remain competitive. This interorganizational relationship allows participating organizations to combine resources, knowledge and power with each other, in addition to collaborating to better deal with the identified joint work opportunity. However, despite having a mutual or compatible goal, it is common for these organizations to face several challenges during the partnership. This research project aims to explore the management of interorganizational relationships, both at the private and government levels. The understanding of the life cycle of interorganizational relationships and the application of modeling techniques for Objectives and Business Processes, Collaborative Systems, Knowledge Management and Project Management enable the design of a support framework for the management of interorganizational relationships. This framework supports the integration and monitoring of participating organizations, enables the interoperability of processes and information, and allows the development of skills for joint action and the achievement of shared objectives, thus ensuring that joint work will be effective and successful.

Description:
This research project aims to create a flow monitoring system in Software Defined Networks based on weathermap visualization schemes. This system aims to integrate tools that allow a panoramic view of the data flows that cross an OpenFlow network, as well as their characteristics, allowing to identify the path of each flow within the monitored network. Thus, it is expected that this system will be used to support the dimensioning of network capacity, the definition of routing policies, the verification of the impact of failures and decision making related to traffic engineering and resilience in the data plan.

Description:
Currently, search tools are widely used to support formal and informal learning, but such tools do not consider didactic-pedagogical theories and approaches in their design and evaluation. Thus, Searching as Learning appears as an emerging area of research that is based on the evolution of search engines when contemplating the teaching-learning characteristics. A great opportunity opens up for the Educational Technologies area, which can bring the necessary theoretical foundation to a new generation of search tools, as well as experience in the use of technologies to support Education. The potential for technological research and innovation is widely addressed in this project, by (i) proposing a formalization of the concepts necessary for Searching as Learning (including how educational theories and approaches can relate to the concepts of information retrieval); (ii) analyzing the exploratory search process and how the activities of this process impact the user’s learning; (iii) designing and intervening in search systems, rethinking them with a learning support tool; and (iv) evaluating the exploratory search process and the learning results that occur during a search.

Description:
The main objective of this research project is to produce a system to manage and consult the collection formed by the Núcleo de Memória da Museologia no Brasil (NUMMUS), implemented by the School of Museology at the Human and Social Sciences Center of this University, in 2005. For such, it is possible to enumerate three specific objectives: 1. Develop the prototype of a system for registering and consulting some items in the collection, providing for the issue of accessibility. 2. After validating the prototype, develop a web application of the complete version of the system and oriented to usability and accessibility. 3. Add new technologies to the system, such as, for example, development or reuse/adaptation of ontologies for the semi-automatic classification of elements of the collection, and integration with other data available on the web (semantic web), storage of 3D images, etc.

Description:
This research project aims to produce reflections and identify categories that enable a better understanding of how Information Systems (IS) can be used in social management contexts, for example, social movements, voluntary associations, and non-governmental organizations. The research, based in knowledge derived from social-technical approaches, will investigate questions about how IS are related to social, political and economic dynamics in the contexts mentioned above. Qualitative bias methodologies are used in the research, such as systemic view, actor-network theory, grounded theory, design science research, research-action, among others. The research design is based on multiple and longitudinal case studies, which comprise empirical investigations of questions such as “how?” and “why?” on contemporary phenomena within their real context.

Description:
The class of stream processing applications represents different important processing domains (e.g., image, video, audio, and unstructured data produced by sensors). The project challenge is to enable these applications to run in cloud computing environments rather than running in traditional high-performance processing centers. The cloud computing model enables greater control over the resources and the user can pay-per-use. The elasticity (increase and decrease in the use of computational resources) of these environments allows users to save money when stream processing applications support the proper on-demand resource provisioning. This scenario is quite interesting and appropriate to be investigated in these applications since the intensity of the data flow varies and the computational cost of the operation is often irregular for each item/task being processed. Our goal in this project is to investigate different ways of exploiting parallelism and automatic elasticity. In addition, we intend to provide efficient stream parallelism support for a set of applications from this domain in the cloud.
