Simulation Based Control System for a Manufacturing System

The planning of small batches as well as a high level of product variety manufacturing systems and facilities is more complex when involves automation. Therefore solutions for flexible and fast reacting planning methods are needed. The fast evaluation of a high amount of planned manufacturing systems becomes important. A software-based solution could increase the quality and the efficiency of planning processes. Simulation has gained importance in the evaluation of such systems and will be used to support the evaluation processes. In context of this project, robotic and workplace simulation is utilized in planning, evaluation and realization of the flexible manufacturing system. The simulation model is used in order to create, generate and evaluate a control logic program of the system. The simulation model of manufacturing system is developed by utilizing Tecnomatix eM-Engineer. With the help of Siemens product package STEP 7 Professional, the control logic program of the model is tested in virtual commissioning. After iterative improvement steps, the improved control logic program is implemented in the real system

Remanufacturing approaches contributing to sustainable engineering Abordagens de remanufatura - uma contribuição para engenharia sustentável

Increasing use of resources by an increasing population with unequally distributed wealth make sustainability an urgent topic to pay attention to. A reference model for sustainability in engineering is presented referring to education and research, management, technology, processes and products as the relevant issues for a global change to sustainability. The European environmental laws for sustainable development are an attempt to cope with this challenge by legislative means. The provocative reality of practical implementation in dealing with electric and electronic products after their usage phases in Europe is illustrated. Laboratory developments in disassembly and testing demonstrate the feasibility of remanufacturing. In addition, approaches to increase the efficiency of remanufacturing by improving the product design are introduced.O crescente uso de recursos gerado pelo contínuo crescimento populacional inserido em um cenário de distribuição desigual de riqueza faz do termo sustentabilidade um tópico urgente para discussão. Neste artigo, apresenta-se um modelo de referência para sustentabilidade em engenharia que aborda questões relevantes para uma mudança global no caminho para a sustentabilidade, priorizando os seguintes elementos: educação e pesquisa; gestão, tecnologia, processos e produtos. As leis ambientais da União Européia esforçam-se para tratar com responsabilidade esse desafio de desenvolvimento sustentável. A realidade de implementações práticas em consideração a produtos eletro-eletrônicos depois de sua fase de uso é ilustrada no artigo. Desenvolvimentos em laboratório de desmontagens e testes demonstram a viabilidade da remanufatura. Além disso, abordagens para aumentar a eficiência do processo de remanufatura a partir de melhorias no processo de desenvolvimento do produto são também sugeridas
