1. Assessment of shop floor layouts in the context of process plans with alternatives
Abstract Paper aims The paper seeks to compare the performance of three layouts in a make to order (MTO) production system with high product variability. Originality No previous work sought to compare job shop, cellular and virtual cell layouts in an MTO system with high product variability, with just 21 resources, a low amount. The analysis considered m

5. Solidification microstructures and mechanical and corrosion resistances of dilute Pb-Sn alloys / Microestrutura de solidificação e resistencias mecanicas e a corrosão de ligas Pb-Sn diluidas
Lead-acid batteries manufacturers have modified the manufacturing processes and the chemical composition of alloys used in battery grids in order to decrease their weight as well as to reduce the production costs, and to increase the battery life-time cycle and the corrosion-resistance. The morphological microstructures characterized by cellular and dendriti

7. Comparação de desempenho entre as configurações celular, funcional e celular virtual através de simulação e projeto de experimentos
The appropriate choice of the production management system and the physical layout of the shop floor are fundamental for the viability of an industrial activity in the current globalized and highly competitive economy. More and more specialized products, with successively shorter life cycles seek to respond to the frequent market changes, demanding an agile

8. Produção de quimosina B de Bos taurus em Pichia pastoris
Enzymatic milk coagulation for cheese manufacturing involves the cleavage of the scissile bond in κ casein by an aspartic protease. Bovine chymosin B is commonly used at the industrial level for milk coagulation because it combines a strong clotting activity with a low general proteolytic activity. In the present study, we report the expression, purific

10. Classification method of elements that cause the run-up period in changeover / Metodo de classificação dos elementos do periodo da retomada de produção
The setup time reduction methodologies gained importance when the industry was challenged to produce in small lots and high variety with the same production system. In the historical context, SMED methodology, elaborated by Shigeo Shingo, a Toyota Motors Company consultant, deserves special attention. His methodology has given prominent steps in terms of eva
