Estudo sobre eficiência energética em uma unidade industrial

This work contemplates an opportunities study of the rational use of energy in an industrial unity from the demand analysis and electrical energy consumption. Through a guide of energy analysis it was described how to find the main problems that create energy wastes in an industry, showing the ways so the production processes avoid such wastes and start to use energy in a more sensible e efficient way. It was also studied, the technical e economical viability of possible interventions to be implemented in terms of energy conservation and of possible demand supply alternatives

Joint economic design of X̄ and R control charts for processes subject to two independent assignable causes

A model for the joint economic design of X̄ and R control charts is developed. This model assumes that the process is subject to two assignable causes. One assignable cause shifts the process mean; the other shifts the process variance. The occurrence of the assignable cause of one kind does not block the occurrence of the assignable cause of another kind. Consequently, a second process parameter can go out-of-control after the first process parameter has gone out-of-control. A numerical study of the cost surface to the model considered has revealed that it is convex, at least in the interest region.

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

Oxidação e remoção de ferro e manganês em águas para fins de abastecimento público ou industrial: uma abordagem geral

The iron and manganese ions are present in a high frequency in water source in Brazil. Despite of the frequency in which such problems occur, the way the problem is faced is still traditional, i.e. focusing on oxidative process instead of solid-liquid separation. The treatment can be very simple, in groundwater, or very complex, when metals are present together with organic matter in water. This article presents a review of principal works besides some important aspects about iron and manganese in natural water, occurrence, forms in natural water, organic complexes, oxidation and removal applying solid/liquid separation processes. Further, a new strategy for iron and manganese removal is presented. The information described does not exhaust the matter, so a large bibliography was cited at the end of the article.

Innovation in industrial clusters: a survey of footwear companies in Brazil

The aim of this study is to characterize the relationships in innovation and business clustering processes in the productive chain of small and medium enterprises (SME) of Brazil. The object of study are SMEs the local procuctive cluster of the shoes in Franca, State of São Paulo. The conceptual model developed is based on the following constructs: vertical integration, innovation and characteristics of the cluster, and it is focused on identifying the agents that act predominantly in product innovation processes in the cluster. A survey was conducted. It was found that there is cooperation between the companies in the productive arrangement studied, and that shoe manufacturers are those who, predominantly, stimulate innovation within the cluster.
