Federal Fluminense O objetivo do presente estudo consiste na identificação de oportunidades de melhoria em processos de produção de uma serralheria. Como método, serão utilizadas técnicas da gestão da qualidade em conjunto com a modelagem de processos, através da notação BPMN. Inicialmente, foi aplicado o diagrama de Ishikawa para identificação das possíveis causas e correlações para os gargalos encontrados. Posteriormente, foi utilizado o método dos "5 por quês" para identificar as causas raízes do problema em questão. O atraso na entrega de projetos foi identificado como principal oportunidade de melhoria para a empresa, sendo apontando como ação de melhoria o investimento em treinamento de seus funcionários, assim como a descrição de procedimentos, para evitar erros durante as operações. A mudança no fluxo operacional também foi sugerida, através do diagrama "TO BE" que contém as melhorias no processo com base no problema e nas causas identificadas. Palavras-chave: BPMN. Gestão de processos. Redesenho de Processos. The objective of the present study is to identify opportunities for improvement in production processes through their mapping, using tools and techniques of quality management, and to propose their redesign by BPMN notation. Initially, the Ishikawa diagram was applied to identify the possible causes and correlations for the bottlenecks encountered. Subsequently, the "5 why's" method was used to identify the root causes of the problem in question. The company was advised to deal with the delay in the delivery of projects, pointing out that improvement could come with the training of its employees, as well as the description of procedures, in order to avoid errors during operations. A change in operational flow has also been suggested, through the "TO BE" diagram which contains process improvements based on the problem and the identified causes.
Team formation is a key aspect of football, being able to bring sporting and financial results, but also susceptible to great risks. Considering that this problem involves subjective decisions, it also becomes subject to failures. The use of quantitative approach methodologies can overcome such aspects and offer better results for football clubs. In this context, a systematic review was carried out on Operations Research techniques for player selection and formation of football teams, demonstrating the main references and authors of the area. A search on the scientific bases Web of Knowledge, Scopus, and ScienceDirect was carried out during the month of January of 2018, analyzing a total of 1,637 articles. Of these, only 12 were selected for analysis. The research of Boon and Sierksma (2003) was identified as the main reference of the area, being referenced by four other authors. It is highlighted the low number of citations between the papers, as well as the lack of review articles like this one. All these aspects contribute to the relevance of this research, addressing a significant problem in one of the most popular sports in the world and unifying its main references.
Companies seek to improve service level, aiming to meet the most demanding customers that enable it survives in a complex and competitive marketplace. The article presents a study in a company of repair and maintenance of industrial equipment and instruments, located in Campos dos Goytacazes (RJ), aiming to identify the factors that influence the execution time of the operators' activities in the manometer calibration process. For this scope, the study of times and movements and statistical analyzes, such as Linear Regression and ANOVA, were applied. The survey revealed that operators who have completed their technical courses in mechanics perform the activities in standard time greater than those who have not yet completed and that working on board and being married do not change the execution time. It also revealed that employees of lower age and longer experience are preferable because of shorter operating times and that the age was statistically significant, revealing that the most appropriate age to have a shorter time is approximately 27 years.
For soccer managers, player selection lineups are a key process for better performance, both on financial and sports matters. However, to determine a quality solution to this problem it becomes more complex, as the number of alternatives and criteria increases and the number of viable solutions grows exponentially. This paper proposes a multicriteria method with genetic algorithm for the evaluation of soccer teams based on Brazilian Championship data. A team complementation percentage was calculated considering a total of 322 athletes and 18 criteria. The results presented a 3-6-1 format as the ideal for this case study, obtaining a team complementation value of 43.04%. The method adaptability for the decisionmaker is highlighted, showing it was possible to determinate the most complementary team according to the desired tactical formation and importance attributed for each criterion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
