Algoritmo genético-tabu para a programação reativa da produção em um sistema de manufatura com recursos compartilhados
(Universidade Federal de São Carlos, 2009-11-20) Duarte, Ageu Morais; Morandin Júnior, Orides; https://lattes.cnpq.br/4192845106907956; https://lattes.cnpq.br/0175023747066668
Manufacturing systems with shared resources have been designed to meet the market needs, which require high quality products, low cost and the guarantee of the conditions agreed with the customer. The production scheduling in a manufacturing system is a complex task due to its combinatorial nature. Several studies show the use of search methods, such as Genetic Algorithms (GAs) and Tabu Search (TS), applied to the refinement of the production scheduling problem. The GAs present as disadvantages, the premature convergence, the lack of search intensification mechanisms in promising regions and also the lack of mechanisms which maintain the diversification of the population. In order to make GAs more effective in their search, by avoiding the premature convergence and ensuring the population diversity, some mechanisms are added to them so as to adjust their parameters during the search process, the so called Adaptative Genetic Algorithms (AGAs). However, these mechanisms do not guarantee the search intensification in the promising regions found. On the other hand, the TS presents mechanisms of search intensification and diversification, although its computational time depends on how optimal its initial solution is (solution by which the search process starts). In order to overcome the limitations of the traditional search methods, the Hybrid Algorithms (HAs) have been developed. They consist of the association of one method with another so that one helps the other in its deficiencies . This dissertation proposes the development of a Genetic-Tabu Algorithm (GTA) applied to the problem of the production reactive scheduling in a manufacturing system with shared resources, in order to ensure good compromise between makespan values and feedback time. The TS will be a functionality added to the AG and to the AGA, in other words, it will be a procedure to refine the individual(s) of the initial position and also to refine the individual obtained by the search methods. Tests have been conducted to determine which selection method (roulette or tournament) is more adequate for the definition of the neighborhood structure and also for the definition of the time to apply the mutation operator. Besides, other tests have been conducted by using different ways to calculate the makespan; one of them proposed in this dissertation and the others by Deriz (2007) and by Sanches (2008).
Elaboração e avaliação de conteúdo educacional para educação a distância sobre úlceras por pressão
(Universidade Federal de São Carlos, 2009-11-20) Casaburi, Paula Regina; Zem-Mascarenhas, Silvia Helena; https://lattes.cnpq.br/0185144417072417; https://lattes.cnpq.br/6430250104416309
In search of qualification, the nursing searches increasingly a continuous update of all the team. One of the strategies that can be used for professional training is the education in service. In this perspective, for the creation of educational projects for training, the nursing has several technological resources in the health institutions and the computer is a facilitator of teaching activities and upgrade. The use of distance education mediated by computer finds wide application in the educational process, providing cost savings and increases the flexibility of teaching. In this context, this project aimed to develop and evaluate an educational content about pressure ulcers to the EAD. For this, placed a survey of the knowledge of a nursing team who worked in an outpatient unit on the prevention and treatment of chronic skin ulcers (pressure ulcers) to support the development of educational content. The development of an educational content about pressure ulcers used the Planning Learning Activities Supported by Computer based on the concepts of the Theory of Meaningful Learning. The course about prevention and treatment of pressure ulcers was created in the virtual learning environment Moodle, using as a structure a division by chapters and consists of an introductory text, introductory exercises, revealing the knowledge (educational content) and the full text. In addition, a glossary, chat, discussion forums, course evaluation, recommended links, notice board and contact have been used as tools. In the final step of this study was made an assessment of educational content for expertises in the nursing subject and distance education. In the assessments were highlighted by all the evaluators the scientific rigor and update of the course available. Also identified some areas for improvement, as increase interactivity with the student and improve the quality of the images presented. This work was possible to verify the importance of information technology for the development of distance education courses for nursing and health education, and the importance of researches about skin ulcers. We identified that the creation of courses with the help of a multidisciplinary team is a strategy that we must use, searching with this the creation of interactive courses with the students, providing greater adherence and understanding of the material provided. We 11 conclude that despite the continued growth of distance education, several investments are still needed to reach the same one of its purposes that is to expand the science education.
Análise da planta genérica de valores por meio de estrato de renda no município de São Carlos
(Universidade Federal de São Carlos, 2009-11-20) Medvedchikoff, Tatiana Gakiya; Röhm, Sergio Antonio; https://lattes.cnpq.br/7332654261230826; https://lattes.cnpq.br/5327141817744769
The tax planning is necessary for there to be a rational application of resources and improvements in basic infrastructure for the municipality. Therefore, the assessment and questioning of the results indicated in the Generic Plant Values can provide information to the legitimacy of taxation more fair and accessible. This study evaluated the consistency of values existing plant in São Carlos - SP with respect to income levels provided by the Brazilian Institute of Geography and Statistics (IBGE). The methodology used algebra through the Spring software. The results indicated possible inconsistencies between the income strata and venal values established. It is concluded that the plant venal values could be more efficient if they changed the criteria for charging for urban voids and taken into account the income strata of the taxpayer.
