Diagóstico ambiental de empreendimentos do distrito industrial Antônio Crepaldi – Presidente Prudente/SP

Recently, the environmental concern has grown due to the higher awareness about the availability and the importance of natural resources for survival on the Earth. So, laws and regulations were implemented aiming the environmental preservation. It has being developed new systems, technologies and techniques in order to minimize wastage of resources and minimize waste generation that may cause environmental impacts, in order to abide by the laws and regulations. These techniques and systems have been developed mostly for the industrial sector, because it’s one of the most responsible for the waste generation and impacts. One of the most employed systems is the environmental management, performed during the environmental diagnosis of the area/activity. So, this study aimed the environmental assessment and the establishment of proposals for the mitigation of the most significant environmental impacts generated in five industries of the Antonio Crepaldi industrial district – Presidente Prudente, in order to contribute to environmental issues and provide greater efficiency in the productive process of these industries...

Uma análise das estratégias de manufatura adotadas por seis montadoras da indústria automobilística mundial

The Brazilian automotive industry has undergone profound changes during the 90’s decade, as a consequence of the market opening up through the liberation of automobile imports. The exposure of the Brazilian domestic market to competition with imported products of high quality and lower prices indicated the need for significant changes in those auto industries operating in this country, with the intention of making them competitive. To achieve these objectives management and production concepts were adopted, such as: the just-in-time philosophy; lean manufacturing; outsourcing; reengineering and increasing the rate of automation in both production and management systems. These changes helped to increase productivity and, in turn, reduced the level of employment in the sector, especially in activities where the required qualification levels were low. Despite this modernization, the Brazilian companies have committed themselves to meet the specific needs of the Brazilian market. The objective of this paper is to analyze and present manufacturing strategies from six manufacturers of automotive vehicles: Toyota in Japan, Fiat in Italy, Volkswagen in Brazil and Germany and General Motors in the U.S. and Brazil. The predominant method of research was from reviewing relevant literature, whereas the empirical data was analyzed qualitatively. The article seeks to identify the manufacturing strategies adopted by manufacturers located in the above countries, electing one automotive manufacturer to represent each country. The research demonstrated that the processes for production of automobiles in four plants located in, the U.S. (GM); Italy (Fiat); Japan (Toyota) and Germany (VW) are similar to those adopted in Brazilian industrial plants of the same companies (GM and VW), with differences of operations only in the business strategies adopted by each of them.

Planejamento para a implantação da ISO 9001 em uma empresa do setor industrial

The fierce competitiveness of the current market and the sophistication of customer requirements made the commitment to quality a need within organizations. The search for quality has been carried out by the adoption of quality management systems, a formal organization that should be present throughout the organization, from the initial identification of market needs to the satisfaction of customer requirements. The methodology most commonly used for this purpose is based on the requirements of ISO 9001, latest version of 2008. Considering this scenario, was developed a case study in a small company of the industrial sector with the development of a plan for the implementation of ISO 9001. The proposed methodology involved the construction of a theoretical framework on the subject and the development of a case study with a qualitative approach. Initially, was applied a questionnaire to the representative of the organization about the company's operating procedures, activity logs held, current documentation, planning and resource management for the construction of an assessment about the adequacy of the company needs to ISO 9001. Were obtained as results the characterization of production processes and organizational structure of the company and examples of policy and objectives of quality, performance indicators, document control, system for visualization of non-compliances, among others. Finally, the benefits of adopting a quality management system based on ISO 9001 requirements for the company and its environmental issues such as increased process efficiency, less waste and greater profitability, were pointed out, and the conditions for effective certification in the future

Desenvolvimento de um sistema de controle para avaliação de fontes de energias renováveis no bombeamento de água

The use of alternative energy systems in the current days is an urgent necessity due to the problems that the planet is facing as the heating and loss of ozone layer. The scarcity of conventional energy is another problem that must be solved for the future of humanity. It must be considered that the people are inhabiting places moved away not always with available energy. The application of technologies as automation and control can help us to solve this problem. Therefore, this work aimed at apply an equipment of industrial usage, the Programmable Logical Controller, PLC, in alternative energies systems, as eolic generation and fotovoltaic generation used for water pumping, aiming the automatic control and the efficiency in the places where it has simultaneous availability of these sources, based in criterion of priority that previously established itself between them. It was made a hydraulic and energetic evaluation of the energy system, eolic and fotovoltaic, used in the automatic control system of pumping, in the place of accomplishment of the experiment, according to previously established physical conditions. The results have shown that the control system using the PLC is practicable and has trustworthiness. The program developed can be adapted for the use with several power plants in a specific application place. The fotovoltaic system of pumping, using a polycrystalline of 70 Watts connected to a pump Shurflo 8000, showed to be efficient with significant flows in almost all the months. The eolic system of pumping, using an eolic generator of 400 Watts assembled in place of experiment, did not demonstrate energetic capacity for use in this specific type of application.
