Atualmente setor elétrico brasileiro está estruturado sobre a disponibilidade das unidades geradoras, subestações e linhas de transmissão. Com a aplicação das regras do novo modelo do setor, tanto as empresas de geração como as de transmissão, passaram a ser submetidas a mecanismos que penalizam a indisponibilidade, causada por desligamentos forçados ou programados, dos seus ativos. Para evitar a aplicação destes mecanismos, e outras penalidades, que causam grandes prejuízos, é preciso que o processo de manutenção garanta a disponibilidade e confiabilidade, dos equipamentos e instalações. Este trabalho propõe um método de gestão da produção, também direcionado para a eliminação das perdas existentes no processo de geração e transmissão de energia elétrica, adaptado da Manutenção Produtiva Total – TPM. O desenvolvimento do método está baseado no estudo da aplicação da TPM nas plantas de geração e transmissão da Eletrobras Eletronorte. O método proposto deverá fomentar a gestão da qualidade não só na manutenção e operação (O&M), mas também em todos os processos que possam impactar na disponibilidade dos ativos de geração e transmissão.

The process of product development (PPD) is a strategic factor in which companies seek to identify consumer needs. The relationship of the practices adopted, tools, techniques, among others, can determinate the maturity level of the company in this process. The purpose of this paper is to understand and diagnose the level of maturity of the PDP in footwear segment industry. For the case study, a company inserted into one of the largest poles of women’s footwear in Brazil, located in Jaú, São Paulo State, was researched. The diagnosis is based on the maturity levels of the unified model, reference in the process of product development, proposed by Rozenfeld et al. (2006). The application of the model assisted to diagnose the current maturity level of the company in this process, providing useful information to achieve higher levels of maturity in the PDP.

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.

In search for better competitiveness, the automotive industry has discussed and applied several concepts related to people and processes. However, in many organizations, the adopted concepts are implemented and kept unarticulated. In this context, authors recognize the role of the knowledge as competitive advantage, but it is still dealt in an implicit way with the traditional models of Production Management. Exploring opportunities in this scenario, this Thesis aims to analyse worker knowledge sharing using factors of Knowledge Management, Work Organization and Production Organization. For the realization of the present Thesis, the scope of the research was restricted to be the labour environment of the glass plants shop floor. The choice of the glass sector is justified due to high dependency on the tacit knowledge of blue-collars. The research uses a qualitative-quantitative approach and employs interviews with workers and managers to identify factors. To assess the importance of these factors in the management judgments, is employed the technique Incomplete Pairwise Comparisons based on Analytic Hierarchy Process Saaty (2001). The result indicates integration among factors and highlights the importance of systematic and technical conversation among operators to share better your knowledge. Also, worker knowledge sharing is improved using communication, training and work instruction. This research extends the conceptual frameworks encountered in literature from the factors integration of Knowledge Management with the Organization of Work and the Production and makes explicit use of the theme of knowledge. This contributes to promote of a favourable context for the creation and sharing of knowledge, among the people in the labour environment, and to support incremental innovation

Many researchers emphasize the increasing dynamics of business globalization, virtually as a new order of driving rules to be considered and included regarding operations management. In this sense, and trying to attain a set of suitable competitive conditions according to the needs of their business, the very internal processes of management and decision making have been growing in terms of complexity and range of issues to be considered. To do so, it is important to understand and absorb possible changes in competitive conditions as they arise. This paper aims to present a conceptual model and a case study to illustrate the assessment of the relationships involving actors within an operations network. The understanding of the basis behind these relationships and the identification of the existing hierarchic profile governing them, represent primary items to be considered embedded in a decision making system. The results obtained suggest the possibility to make use of the proposed model as an auxiliary tool to assess existing relationships within an operations network.

The local productive arrangements (LPA) are organizational mechanisms that enable the continuous performance of small businesses in production processes and business management models. To promote continuous improvement is essential that companies make decisions based on data that reflects business’ performance (performance measurement) and promote the cluster performance. This way, the aim of this article is to describe the performance measurement process that will support the corporate management of Micro and Small enterprises (SME) of a Local Productive Arrangement in Maringá, State of Paraná, Brazil. To develop this paper, the bibliographic search and action research methods were used. The field research was developed from the cooperation project (PROJVEST) conducted at the LPA, which goal is to deploy improvement actions in project’s participating companies. Metrics and performance indicators constructed from the diagnosis in the areas of Production, Quality and Ergonomics in companies will be presented. Among the main results, can be pointed out that the performance management of LPA is promoting the introduction of corporate management practices in SMEs, stimulating business cooperation, the continuous innovation in manufacturing processes and product quality and business processes.

The social networking sites have experienced a large and rapid growth in recent years and bring together millions of users in Brazil and worldwide. Such networks allow adding groups of people with common interests or relationships, enabling members of this group to communicate and exchange information. Some social networks have specific goals, for example, aggregate individuals with common interests and professional relationships. However, they all share information in some way, whether in the form of short texts, photos, videos, among others. Sharing information in files is also a growing activity on the Internet and can be done in various ways, from sending files via email to multiple contacts to make available areas shared by the same contacts. However, applications are not yet available to enable file sharing on Facebook, considered the premier social network today. Given the growing demand for sharing files over the Internet, and a large number of users familiar with the use of these integrated applications for Facebook there is a demand for applications that allow users to share files with their contacts in this social network. This study aims to investigate how users use Facebook, and their practices for file sharing. It is believed that the results will substantiate future projects to develop software for file sharing on Facebook. Due to the exploratory nature of this research, the choice was made for a survey to collect data, applied through the web. From the results obtained, was possible to observe a frequent use of file sharing, but no interest in paid services. Regarding Facebook, was possible to observe their extensive use in both the frequency of access as the hours spent, as well as an increased use of applications (games, quiz, etc.). The full set of results shows a favorable environment for developing applications for sharing files on Facebook.
