Modelo de simulação computacional para balanceamento de linhas de produção das empresas cerâmicas de São Miguel do Guamá: um estudo de caso
(Universidade Federal do Pará, 2013-10-16) SILVA, Denilson Costa da; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065
This work is to present a computer simulation model for the purpose of solving the problem of balancing production lines of a factory belonging to the polo red ceramic potter-ceramic São Miguel of Guama. In this sense, it is initially performed a literature search on the discrete event systems, the methods of solution for line balancing and concepts involving the modeling and simulation. The methodology addresses the case study, which is conducted by the method proposed by Chwif (1999) in which covers three (03) macros stages in conducting a simulation project, whether the stage of design, implementation and analysis stage. With the computational model developed based on the current characteristics of the production line, one can describe the current state of the process, identify the problem operation as well as forward proposals for improvements from the construction of 03 scenarios. Where the third scenario presented the best results and, therefore, being the representative model of the balancing. At the end, it is understood as the main contributions of this work even bringing into the university experience of the practical application of simulation involving a ceramic industry of São Miguel of Guama and offer the industry of this region a potential tool for improving their processes productive.

Tilojo solo cimento com adição de rejeito de manganês do sudeste paraense
(Universidade Federal do Pará, 2015-04-24) NASCIMENTO, Antonio Carlos Santos do; MACEDO, Alcebíades Negrão; http://lattes.cnpq.br/8313864897400179
The housing issue, with regard to constructive inputs used, it is urgent for a paradigm shift that provides the adequacy of the project, many local specificities, as well as playing practice in man in its territory. Considering the Amazon that, like other areas of the country goes through an intense densification of cities, it is still the scene of action, not always positive, large mining projects, which in its wake, bring the issue of disposal of the waste to add the local issues. This work proposes as a solution path for the problem of mineral waste and constructive input: the soil-cement with the addition of mineral waste brick, reject it originates from the southeast of Pará manganese exploration Because the soil with cement brick. waste mineral manganese meet the requirements set by the NBR 8491/2012, presented compressive values above individually to 1.75 MPa, water absorption values lower than 20%, and negligible dimensional change, it still demonstrates its suitability major weather of the region - ultraviolet radiation and humidity - due to the results obtained in the accelerated aging test chamber. The results show promise, and beyond to suit the rules do not interfere significantly in the production process already developed, has large membership possibilities, contributing to building a new paradigm of development.
