1. HYBRID MANUFACTURING SYSTEM WITH THREE OPTIONS OF REMANUFACTURED AND DISPOSAL ITEMS
ABSTRACT This study is devoted to the optimal control of a hybrid manufacturing system with returned products after usage, represented as an infant mortality mode under a periodic review policy. Three hybrid models have been discussed; remanufacturing is continuous along the planning period (without a disposal option), remanufacturing happened in the second

2. Optimal design of a set of permanent magnet generators with the same cross-section
The optimal design of a set of two permanent magnet generators that share the same cross section to reduce the manufacturing cost is presented using a gradient optimization algorithm. The optimization tool is used to define the optimal number of pole pairs of the set of machines and the optimal permanent magnets width respecting the geometrical and performan

4. The contribution of manufacturing industry in software development / A contribuição da indústria da manufatura no desenvolvimento de software
Os Métodos Ágeis surgiram no final da década de 90, como uma alternativa aos métodos prescritivos de desenvolvimento de software. Eles propõem uma nova abordagem de desenvolvimento, eliminando gastos com documentação excessiva e burocrática, enfatizando a interação entre as pessoas e as atividades que efetivamente trazem valor ao cliente. Nos últi

7. Desenvolvimento de um programa computacional para a integraÃÃo de dados de projeto, fabricaÃÃo e mediÃÃo de peÃas torneadas com Ãnfase na sÃntese de tolerÃncias dimensionais determinÃsticas
The objective of this work was to develop a computer program called Manufacturing Management System â SGF developed with the Excel language. This software integrates three stages: design, manufacturing by machining and measurement. So, itâs divided in three different and independent modules: design, manufacturing and measurement. In the design module is pr

8. Manufacturing constraints applied to the topology optimization method. / Restrições de manufatura aplicadas ao método de otimização topológica.
The design of a mechanical component is a very complex task, which includes constraints such as maximum weight and maximum stiffness, and also manufacturing constraints, associated with the manufacturing processes required at the shop floor. It is known that Topology Optimization (TO), despite of being a very effective and powerful method to obtain optimal s

9. AplicaÃÃo da teoria das restriÃÃes para otimizaÃÃo dos sistemas de produÃÃo em uma empresa do setor quÃmico
Todayâs businesses environment are highly competitive. The organizations search for cost, quality and leadtime advantages. Now the company that not to strive to improve quality, reduce leadtime and cost and lower the working capital, will not survive. The Theory of Constraints consists in a tool created for system optimization. The Theory of Constraints was

10. Proposta de um método de participação da produção utilizando o desenvolvimento enxuto de produto
Lean manufacturing tools are well known and implemented to eliminate waste and improve materials flow throughout a production process. These lean principles are now studied and applied to product development process (PDP), aligned to the companys needs to develop and launch new products with lower cost and increased speed. Therefore, the objective of the pre

11. Product mix decision: comparing theory of constraints, activity based costing, general model and discretionary cost considered discretionary cost. / Decisão de mix de produtos: comparando a teoria das restrições, o custeio baseado em atividades e o modelo geral com a utilização de custos discricionários.
The optimal product mix selection must consider internal and external factors of a manufacturing company. The external ones are mainly products prices, industry competition, substitute and complementary products, distribution channels, industrial location, and government taxes among others. The internal factors are related mainly to the use of the industrial

12. Relaxação lagrangeana com fixação de variáveis aplicada ao problema de sequenciamento em uma máquina
This paper deals with the Single-machine Scheduling Problem. This kind of problem arises in several practical situations, such as the problems of planning operations on machines in a manufacturing industry. The Single-machine Scheduling Problem consists in sorting n jobs to be processed on a single machine. The jobs are independent and the machine can only e
