Interlocutor: uma metodologia de mediação coletiva em trabalho cooperativo suportado por computador. / Interlocutor: a methodology of collective mediation by computer supported cooperative work.

Barros, Edson de Almeida Rego 17 August 2006 (has links)
A presente pesquisa tem como objetivo identificar e explorar uma metodologia na área de Trabalho Cooperativo Apoiado por Computador (Computer Supported Cooperative Work – CSCW), que aborda processos colaborativos unindo indivíduos, assim como grupos, para que possam trabalhar em conjunto visando metas comuns, estando fisicamente ou não no mesmo local, atuando de forma síncrona ou assíncrona. A metodologia proposta procura reunir o conhecimento de várias pessoas sobre determinados temas, por meio de um sistema de comunicação em rede de computadores, transformando o grupo de indivíduos em uma única voz, sendo o sistema o Interlocutor do grupo. O Sistema Interlocutor funciona em rede e depende de três módulos: o Interrogador que é a comunicação com o meio externo, o Colaborador que é o canal para participação dos membros do grupo, e o Servidor que controla o funcionamento de todo o aplicativo. A metodologia Interlocutor é inspirada em conceitos extraídos de várias áreas tais como Inteligência Coletiva, método Delphi, estrutura de Comitês, Sistemas de Apoio à Decisão (Group Decision Support System - GDSS), Grupos de Trabalho (Groupware) entre outros. Esta metodologia pode ser empregada em situações críticas, que demandam respostas rápidas e precisas, ou mesmo em contextos planejados nos quais se deseja estudar alternativas detalhadamente. Na presente tese são apresentados três possíveis cenários de aplicação da metodologia proposta, bem como possíveis configurações para futuros estudos mais apurados. São apresentados ainda os resultados dos testes efetuados em um desses cenários que validaram a metodologia. Em conclusão, a metodologia Interlocutor é uma forma para a criação e o funcionamento de sistemas capazes de obter resultados de Inteligência Coletiva. / The present research aims to identify and to explore a methodology in the area of Computer Supported Cooperative Work (CSCW), encompassing cooperative processes that joint individuals, as well as groups, in a way that they can work seeking common goals together, being or not physically in the same place, acting synchronously or asynchronously. The proposed methodology searches to gather the several people's knowledge on certain themes, through a communication system in net of computers, transforming the individuals' group in a single voice, being the system the Interlocutor of the group. The Interlocutor System works in net and it depends on three modules: the Interrogator that it is the communication with the external middle, the Collaborator that it is the channel for participation of the members of the group, and the Servant that controls the operation of the whole application. The Interlocutor Methodology is inspired in extracted concepts of several such areas as, among others, Collective Intelligence, method Delphi, structure of Committees, Group Decision Support System (GDSS), Groupware. This methodology can be used in critical situations, that demand quick and necessary answers, or even in planned contexts in which it is wanted to study alternatives in full details. The present thesis presents three possible sceneries of application of the proposed methodology, as well as possible configurations for futures approaches. It is also presented the results of the tests made in one of these sceneries that validated the methodology. In conclusion, the Interlocutor Methodology is a form for the creation and the operation of systems capable to obtain results of Collective Intelligence.

The Effect of Decision Aids on Work Group Performance

Hacker, Marla E. 10 April 1997 (has links)
Organizations increasingly use work groups to perform process improvement tasks. Little research exists about groups assigned complete tasks such as process improvement which involves completing all group processes, such as: generating, selecting, negotiating, and executing. This research tested the impact of decision aids on work group processes and work group performance. Laboratory and field experiments were performed. Decision aids were shown to impact work group processes. Decision aids increased the number of ideas considered by the work group, increased the equality of participation in the work group, decreased the overall level of conversation, and reduced consensus during evaluation of sensitive issues. No significant difference was found between decision aid types and work group performance. A regression model was identified which predicts group performance. Two variables were high predictors of work group performance: the level of conversation occurring in the group and the range between high and low idea contributors. The range between high and low idea contributors was correlated with the skill level of participants in the group. / Ph. D.

Drake, Robert Gervase 12 1900 (has links)
Approved for public release; distribution is unlimited / The goal of this study is to provide a single source of data that enables the selection of an appropriate voice recognition (VR) application for a decision support system (DSS) as well as for other computer applications. A brief background of both voice recognition systems and decision supports systems is provided with special emphasis given to the dialog component of DSS. The categories of voice recognition discussed are human factors, environmental factors, situational factors, quantitative factors, training factors, host computer factors, and experiments and research. Each of these areas of voice recognition is individually analyzed, and specific references to applicable literature are included. This study also includes appendices that contain: a glossary (including definitions) of phrases specific to both decision support system and voice recognition systems, keywords applicable to this study, an annotated bibliography (alphabetically and by specific topics) of current VR systems literature containing over 200 references, an index of publishers, a complete listing of current commercially available VR systems. / http://archive.org/details/applicationofvoi00drak / Lieutenant, United States Navy

Shared displays to support collaborative exploration of ocean summits

Lai, Sherman 05 1900 (has links)
In group decision support systems, understanding the roles, dynamics and relationships between participants is imperative to streamlining the decision-making process. This is especially true when decision makers have varying interests. Research has shown that decision-making processes amongst groups with varying interests will often reach bottlenecks with issues, such as unwillingness to share information, or a limited ability of the participants to share ideas at the same time. We explored this research territory of group decision-making by implementing collaboration software to support Ocean Summits, a new approach that uses real-time simulations as part of the decision-making process for stakeholders to explore fisheries management policies. The research reported in this thesis has three goals: (1) to better understand the decision-making process in fisheries management, (2) to build a prototype system to tackle the major issues in the decision-making process and (3) to determine the best way to share and display information critical to the stakeholders' decision-making process by exploring the use of shared screens and information in comparison to private displays. We discovered that the use of shared screens with shared information yielded the best results, as opposed to private screens with shared information or private screens with private information. It was observed that sharing information allowed participants to explore more alternative solutions.

Developing A Group Decision Support System (gdss) For Decision Making Under Uncertainty

Mokhtari, Soroush 01 January 2013 (has links)
Multi-Criteria Decision Making (MCDM) problems are often associated with tradeoffs between performances of the available alternative solutions under decision making criteria. These problems become more complex when performances are associated with uncertainty. This study proposes a stochastic MCDM procedure that can handle uncertainty in MCDM problems. The proposed method coverts a stochastic MCDM problem into many deterministic ones through a Monte-Carlo (MC) selection. Each deterministic problem is then solved using a range of MCDM methods and the ranking order of the alternatives is established for each deterministic MCDM. The final ranking of the alternatives can be determined based on winning probabilities and ranking distribution of the alternatives. Ranking probability distributions can help the decision-maker understand the risk associated with the overall ranking of the options. Therefore, the final selection of the best alternative can be affected by the risk tolerance of the decisionmakers. A Group Decision Support System (GDSS) is developed here with a user-friendly interface to facilitate the application of the proposed MC-MCDM approach in real-world multiparticipant decision making for an average user. The GDSS uses a range of decision making methods to increase the robustness of the decision analysis outputs and to help understand the sensitivity of the results to level of cooperation among the decision-makers. The decision analysis methods included in the GDSS are: 1) conventional MCDM methods (Maximin, Lexicographic, TOPSIS, SAW and Dominance), appropriate when there is a high cooperation level among the decision-makers; 2) social choice rules or voting methods (Condorcet Choice, Borda scoring, Plurality, Anti-Plurality, Median Voting, Hare System of voting, Majoritarian iii Compromise ,and Condorcet Practical), appropriate for cases with medium cooperation level among the decision-makers; and 3) Fallback Bargaining methods (Unanimity, Q-Approval and Fallback Bargaining with Impasse), appropriate for cases with non-cooperative decision-makers. To underline the utility of the proposed method and the developed GDSS in providing valuable insights into real-world hydro-environmental group decision making, the GDSS is applied to a benchmark example, namely the California‘s Sacramento-San Joaquin Delta decision making problem. The implications of GDSS‘ outputs (winning probabilities and ranking distributions) are discussed. Findings are compared with those of previous studies, which used other methods to solve this problem, to highlight the sensitivity of the results to the choice of decision analysis methods and/or different cooperation levels among the decision-makers

No. of bitstreams: 1 Marinaldo Oliveira Santos_.pdf: 2682832 bytes, checksum: f39463fc89972fe2230fe980b0b16e05 (MD5) Previous issue date: 2016-07-18 / UNISINOS - Universidade do Vale do Rio dos Sinos / A avaliação de desempenho funcional é uma das principais ferramentas de gestão de pessoas, seus resultados dão subsídios ao gestor para o planejamento de ações e políticas de melhorias, visando metas individuais e organizacionais. O caso selecionado para o estudo é a Avaliação Periódica de Desempenho (APED), regulada pelas normas legais representadas pela Lei n. 1.534 de 29 de dezembro de 2004 e pelo decreto n. 2.551 de 13 de outubro de 2005. O presente trabalho tem como objetivo propor melhorias no modelo atual de avaliação de desempenho dos servidores públicos do estado do Tocantins visando ao aprimoramento do instrumento de medição de desempenho por meio do emprego da abordagem de auxílio multicritério à decisão (AMD). Para alcançar este objetivo, foi adotada uma abordagem que combina os métodos AHP e PROMETHEE II, e ainda suas extensões para decisão em grupo, a abordagem de Agregação Individual de Prioridades (AIP) para o AHP e o PROMETHEE GDSS para o PROMETHEE II. Os resultados obtidos pela pesquisa propiciaram o aprimoramento do instrumento de avaliação atual da APED, por meio da definição de pesos para os avaliadores, competências e fatores de avaliação. Somado a isso, a partir do instrumento aprimorado, foi possível reformular o cálculo da nota final do avaliado empregando uma agregação aditiva. Com esses resultados, espera-se a melhoria efetiva do modelo atual de APED, que possibilitará a apresentação de resultados mais precisos em conformidade com o desempenho real das atividades laborais do funcionário, viabilizando a definição de políticas de qualificação de pessoal, valorizando o servidor público a fim de promover, de forma mais eficiente, os serviços públicos. / Functional performance evaluation is one of the main people management tools, its results give the manager subsidies for the planing of actions and improvement policies in order to achieve individual and organizational goals. The case selected for the study is Avaliação Periódica de Desempenho (APED), regulated by legal norms represented by the Law n. 1,534 of December 29, 2004 and the Decree 2,551 of 13 october, 2005. In this thesis I shall propound improvements to the current model of perfomance evaluation of public employees of Tocantins state in order to improve the perfomance measurement instrument through the use of multi-criteria decision aid - MDA approach. To achieve this goal, I adopted an approach that combines the AHP and PROMETHEE II methods, and also their extensions to group decision, the Aggregation Individual Priorities approach (AIP) for AHP and PROMETHEE GDSS for PROMETHEE II. The results obtained by the research, led me to the improvement of the current evaluation tool (APED), by defining weights for evaluators, skills and evaluation facts. Added to this, from the improved instrument, it was possible to reformulate the calculation of the final grade of evaluated using an additive aggregation. With these results it is expected the improvement of the current model of (APED), which will allow the submission of further accurate results in accordance with actual performance of labor employee activities, allowing the definition of qualification of personnel policies enhancing the public employee to provide more efficiently the public services
