Design industrial como fonte de vantagem estratégica: estudo de caso na indústria moveleira

This research was based on the lack of academic investigations which recognize industrial design as an strategic advantages source. It was chosen to adopt a wide approach, not common in administration researches, through which aspects frequently ignored by most of the strategy and marketing literature could be recognized. The investigation took place at a big brazilian company, from the furniture industry, more specifically from the office furniture segment. Two product development cases were selected: one of them classified by the company as an example of success and the other as a failure case. It is an exploratory study. Some important topics were identified, and they may be developed in future researches: the existence of intra-organizational conflicts between marketing and engineering; the big companies' power over market configuration, and the State influence over local markets dinamics.

Processos de aprendizagem e suas influências sobre a acumulação de competência tecnológica : o caso da Empresa Enxuta Industrial Ltda.

Esta dissertação é um estudo de caso sobre aprendizagem tecnológica que, considerando as evidências empíricas descritas no Capítulo 6 e à luz da Tabela 3.1, procurou identificar a trajetória de acumulação de competência tecnológica da Enxuta Industrial Ltda., ao longo do período estudado (1980 - 2000), para as funções tecnológicas de investimentos (decisão e controle sobre a planta e engenharia de projetos), de processos e organização da produção, de produtos e de equipamentos. Para construir a estrutura de competências tecnológicas para a indústria de eletrodomésticos foi utilizada a estrutura desenvolvida por Figueiredo (2000). Por outro lado, considerando as evidências empíricas descritas no Capítulo 7 e à luz da Tabela 3.2, procurou-se identificar a influência dos processos de aprendizagem utilizados pela empresa sobre a sua trajetória de acumulação de competência tecnológica. Os processos de aprendizagem são avaliados à luz de quatro características chave: variedade, intensidade, funcionamento e interação, a partir do uso da estrutura desenvolvida por Figueiredo (2000). Este estudo verificou que o modo e a velocidade de acumulação de competência tecnológica na Enxuta Industrial Ltda. foram influenciados pelos processos e mecanismos de aprendizagem usados para adquirir conhecimento tecnológico e convertê-lo em organizacional. Estes processos e mecanismos de aprendizagem propiciaram a empresa alcançar uma maior velocidade na acumulação de capacidades tecnológicas, quando de sua entrada na indústria de eletrodomésticos, o que proporcionou alcançar o desenvolvimento tecnológico necessário para atuar nesta indústria. Porém, a simples incidência desses processos na empresa não garantiu uma implicação positiva para a acumulação de competência tecnológica. Pois, no período de 1991 - 1995, verificou-se a deterioração do funcionamento dos processos de aprendizagem utilizados na empresa, o que pode ter influenciada negativamente a repetibilidade e a interação daqueles processos. Isto parece ter contribuído para que a empresa falhasse em construir e acumular competências tecnológicas inovadoras naquele período. Através do uso de estrutura existente na literatura, aplicada a uma indústria diferente de estudos anteriores, esta dissertação sugere que deve existir um esforço organizado, contínuo e integrado para a geração e disseminação de conhecimento tecnológico na empresa, o que pode acelerar a acumulação de competências tecnológicas, desta forma propiciando à empresa a construção de uma trajetória de aproximação da fronteira de desenvolvimento tecnológica da indústria.

A situation awareness interface for a bi-wheeled industrial hovercraft: design, development and evaluation

The intention of this thesis is to develop a prototype interface that enables an operator to control a bi-wheeled industrial hovercraft that will work within a fusion power plant if the automation system fails. This fusion power plant is part of the ITER project a conjoint effort of various industrialized countries to develop cleaner sources of energy. The development of the interface prototype will be based on situation awareness concepts, which provide a means to understand how human operators perceive the world around, then process that information and make decisions based on the knowledge that they already have and the projected knowledge of the reactions that will occur in the world in response to the actions the operator makes. Two major situation awareness methods will be used, GDTA as a means to discover the requirements the interface needs to solve, and SAGAT to conduct the evaluation on the three interfaces. This technique can isolate the differences an operator has in situation awareness when presented with relevant information given by each of the three interfaces that were built for this thesis. Where the first interface presents the information within the operator’s focal point of view in a pictorial style, the second interface shows the same information within the same point of view has the first interface but only shows it in a textual manner. While the third interface shows the relevant information in the operator’s peripheral field of view. Also SAGAT can provide insight on the question to know if providing the operator with feed-forward information about the stoppage distances of the bi-wheeled industrial hovercraft has any effect on the operator’s decision making.

Projeto e Operação em Escala Semi-Industrial de um Equipamento para Tratamento de Águas Produzidas na Indústria do Petróleo Utilizando Nova Tecnologia: misturador-decantador à inversão de fases - MDIF

The aim of this work is to use a new technology in the treatment of produced wastewaters from oil industry. An unit for treat produced waters called UTMDIF, was designed, installed and operated in an industrial plant for treatment of effluents from oil industry. This unit operates by means of the method of separation of phase inversion and can become a promising alternative to solve the problem of oil/water separation. This method constitutes the basis of the working of a new design of mixersettler of vertical configuration which occupies small surface area. The last characteristic becomes specially important when there is limitation on the lay-out of the plant, for example, over maritime platforms to explore oil. This equipment in a semi-industrial scale treats produced wastewaters contaminated with oil at low concentrations (ranging from 30 to 150 mg/L) and throughputs of 320 m3/d (47,4 m3 m-2 h-1). Good results were obtained in oil/water separation which leads to the necessary specification to discharge those wastewaters. Besides, the non dependence of the efficiency of separation in spite of the salinity of the medium becomes the equipment an attractive new technology to treat wastewaters containing oil at low concentrations

Anthropotechnological analysis of industrial accidents in Brazil

The Brazilian Ministry of Labour has been attempting to modify the norms used to analyse industrial accidents in the country. For this purpose, in 1994 it tried to make compulsory use of the causal tree approach to accident analysis, an approach developed in France during the 1970s,without having previously determined whether it is suitable for use under the industrial safety conditions that prevail in most Brazilian firms. In addition, apposition from Brazilian employers has blocked the proposed changes to the norms. The present study employed anthropotechnology to analyse experimental application of the causal tree method to work-related accidents in industrial firms in the region of Botucatu, São Paulo. Three work-related accidents were examined in three industrial firms representative of local, national and multinational companies. on the basis of the accidents analysed in this study, the rationale for the use of the causal tree method in Brazil can be summarized for each type of firm as follows:the method is redundant if there is a predominance of the type of risk whose elimination or neutralization requires adoption of conventional industrial safety measures (firm representative of local enterprises); the method is worth while if the company's specific technical risks have already largely been eliminated (firm representative of national enterprises); and the method is particularly appropriate if the firm has a good safety record and the causes of accidents are primarily related to industrial organization and management (multinational enterprise).

Evaluation of neighborhood impacts caused by companies of the high-tech industrial cluster of São Carlos, SP, Brazil

The purpose of this study was to develop a methodology for evaluating neighborhood impacts using a Geographic Information System (GIS) and to apply the procedures to the companies of the High-Technology Industrial Cluster of São Carlos. To this end, an evaluation was made of the neighborhood impacts on the physical environment, urban components, quality of life, and urban infrastructure using impact matrices, and the impacts were assigned scores according to type, order, magnitude and duration. Fifty one companies were examined based on data provided by the companies themselves and on field surveys. The impacts are represented spatially in proportional symbols maps, based on the spatial distribution of the companies in the urban area of the city of São Carlos and the areas of influence of each company. The application of the proposed methodology served to validate it and indicated that the neighborhood impacts caused by the companies of this study are related to each company's type of activity, its size, and its occupation of the area. © 2008 Journal of Urban and Environmental Engineering (JUEE).

Pectin and pectinases: Production, characterization and industrial application of microbial pectinolytic enzymes

Pectinases are a big group of enzymes that break down pectic polysaccharides of plant tissues into simpler molecules like galacturonic acids. It has long been used to increase yields and clarity of fruit juices. Since pectic substances are a very complex macromolecule group, various pectinolytic enzymes are required to degrade it completely. These enzymes present differences in their cleavage mode and specificity being basically classified into two main groups that act on pectin smooth regions or on pectin hairy regions. Pectinases are one of the most widely distributed enzymes in bacteria, fungi and plants. This review describes the pectinolytic enzymes and their substrates, the microbial pectinase production and characterization, and the industrial application of these enzymes. © Pedrolli et al.; Licensee Bentham Open.

Lidar observation campaign of sugar cane fires and industrial emissions in the State of São Paulo, Brazil

Brazil has an important role in the biomass burning, with the detection of approximately 100,000 burning spots in a single year (2007). Most of these spots occur in the southern part of the Amazon basin during the dry season (from August to november) and these emissions reach the southeast of the country, a highly populated region and with serious urban air pollution problems. With the growing demand on biofuels, sugarcane is considerably expanding in the state of São Paulo, being a strong contributor to the bad air quality in this region. In the state of São Paulo, the main land use are pasture and sugarcane crop, that covers around 50% and 10% of the total area, respectively. Despite the aerosol from sugarcane burning having reduced atmospheric residence time, from a few days to some weeks, they might get together with those aerosol which spread over long distances (hundreds to thousands of kilometers). In the period of June through February 2010 a LIDAR observation campaign was carried in the state of São Paulo, Brazil, in order to observe and characterize optically the aerosols from two distinct sources, namely, sugar cane biomass burning and industrial emissions. For this purpose 2 LIDAR systems were available, one mobile and the other placed in a laboratory, both working in the visible (532 nm) and additionally the mobile system had a Raman channel available (607 nm). Also this campaign counted with a SODAR, a meteorological RADAR specially set up to detect aerosol echoes and gas-particle analyzers. To guarantee a good regional coverage 4 distinct sites were available to deploy the instruments, 2 in the near field of biomass burning activities (Rio Claro and Bauru), one for industrial emissions (Cubatão) and others from urban sources (São Paulo). The whole campaign provide the equivalent of 30 days of measurements which allowed us to get aerosol optical properties such as backscattering/extinction coefficients, scatter and LIDAR ratios, those were used to correlate with air quality and meteorological indicators and quantities. In this paper we should focus on the preliminary results of the Raman LIDAR system and its derived aerosol optical quantities. © 2010 Copyright SPIE - The International Society for Optical Engineering.

The formation of the professionals for the timber industrial sector of the civil construction

The common point between the two forms of production of the wood-based sector in Brazil, one practically manufacturing and the other high technology, is in the qualification of the of the labor. In both cases, the professionals are being formed directly in the productive line and rarely with qualification in the academic area. There is not a public political education for the qualification of the labor, and the work market that does not demand qualified professionals, contributes for the sector stagnation. So, in order to excel the socio-cultural barriers in relation to the use of wood in the buildings, new attitudes are necessary in the teaching of the contents of the curricular programs, mainly, in formation of the architect and civil engineering.
