Neste aspecto, o setor de autopeças, situado num mercado de extrema concorrência e de instabilidades, tem procurado a adoção de práticas de fabricação com vistas a promover aumentos em seus índices de qualidade e produtividade. O objetivo deste trabalho é analisar o panorama das indústrias fornecedoras do complexo automobilístico brasileiro, no que diz respeito à adoção das melhores práticas de fabricação. A metodologia utilizada foi o estudo de caso do tipo survey, questionário enviado pelo correio e posteriormente analisado através do uso de técnicas estatísticas. Os resultados obtidos permitiram concluir que a realidade da maioria das empresas analisadas está muito distante quando comparados com as melhores práticas de produção preconizadas pela literatura em questão / Abstract: The increase of international competition and the policies adopted by the Brazilian Government, in the beginning of the decade of 90, have altered the relationships between market and industry. In this point, the automotive suppliers, located in a market of extreme competition and instabilities, has been seeking the adoption of world class manufacturing, to promote increases in their quality metrics and productivity. The aim of this work is to analyze the panorama of the Automotive Brazilian Suppliers, regarding the adoption of ¿world class manufacturing parctices¿.

This treatise takes the form of an impact study. It is based on a three-month period of research involving literature review, interviews with VWSA officers and a survey of 111 of the 5500 workers who comprised the workforce of the VWSA plant in Uitenhage at that time. The author has attempted to portray the general views of experts in the field of HIV/AIDS corporate impact and impact management. In addition he has attempted to assay the current and forecast policies and practices in respect of the management of the epidemic by VWSA. The workers in the plant were consulted by survey and a variety of insights into the level of understanding of the epidemic, tolerance levels, expectations and so on were made. The quantification of these insights must be viewed with caution since the survey sample of 111 was relatively low for a workforce of circa 5500. Calculations in respect of representativity are included to facilitate calculated caution. It has been shown that the HIV/AIDS epidemic has a considerable current impact on the company and that this impact can be expected to grow considerably in the future. It has been suggested that an active intervention program would be well timed if implemented immediately

In this intensely competitive environment of the global economy, the survival of even the most established manufacturers depends on their ability to continuously improve quality whilst reducing costs. The resulting productivity of producing more with less is the only key to market leadership and sustainable competitive advantage. Changing production methods from mass-production to Lean Manufacturing has become the essential practise for successful manufacturers (Rogers and Sim, 2009). The purpose of this study is to investigate what factors negate the adoption and implementation of Lean Manufacturing as a means to gain competitive advantage. The focus was on companies that have participated in the AIDC Tirisano cluster programme. The study investigated what effect Organisational Culture, Leadership Behaviours, Employee Involvement and Strategy Integration have on Lean Manufacturing adoption and implementation. This study applied the mixed methodologies of qualitative and quantitative approaches using methodological triangulation. A cross sectional analytical survey approach in a descriptive case study was undertaken. The findings from the questions and the interviews from the respondents who participated in the survey indicated that the practices in some companies enable the successful adoption and implementation of Lean Manufacturing whilst in some others the practices will negatively affect the adoption and implementation. The study concludes by stating that South African automotive component manufacturers are under immense pressure to improve quality and reduce costs. Initiatives like Lean Manufacturing should be undertaken in order to bring about these improvements. But this improvement comes about by changing the current way of doing things. Companies need to undertake a total approach when implementing Lean as part of the business strategy and this must be driven by management as leaders and a team culture that involves all employees needs to be present.

This dissertation summarises an analysis and assessment of the application of Quality Management Systems (QMS) by Small, Medium and Micro Enterprises (SMMEs), in the Engineering Manufacturing Sector of the greater Cape Town Metropolitan area. An outline of the existing hypothesis derived from previous international SMME studies related to the adoption of QMS by SMME’s, the management’s understanding of quality principles, the potential business benefits of QMS and the reasons for implementing Quality Management systems are given as background to the study. The dissertation includes a discussion of literature on the state of QMS in SMMEs, in particular, recent international research literature hypothesising that SMME management lack essential QMS knowledge and that, in general, most SMME’s do not have a QMS and that SMMEs only implement a QMS as a result of contractual pressures / requirements. Also reported are the results and findings of a survey conducted to test the validity of the existing hypotheses amongst a representative sample of Engineering Manufacturing SMMEs registered with the Cape Regional Chamber of Commerce and Industry in the Western Cape. Results of the survey indicate that almost 90 percent, of the companies surveyed had some type of Quality management System, the only two companies that reported not having a QMS, were companies classified as “Micro”, in terms of the National Small business Act. Analysis of the response to the survey concludes that, in general, more than 80 percent of Engineering SMMEs in the Manufacturing Sector have adopted a QMS based on ISO 9001 and that, on average, their management have a medium to high level of understanding of QMS and the associated business benefits. It is also apparent from survey responses, that companies classified as “Micro” in terms of the Small Business Act of 1996, do not see the need for a formal QM system as the owners of these companies consider them too small for a formal QMS. Instead they take direct ownership of their service and product quality in the face of the customer.

The purposes of this dissertation were to define enterprise resource planning (ERP) systems, assess the varying performance benefits flowing from different ERP system implementation statuses, and investigate the impact of critical success factors (CSFs) on the ERP system deployment process. A conceptual model was developed and a survey instrument constructed to gather data for testing the hypothesized model relationships. Data were collected through a cross-sectional field study of Indian production firms considered pioneers in understanding and implementing ERP systems. The sample data were drawn from a target population of 900 firms belonging to the Confederation of Indian Industry (CII). The production firms in the CII member directory represent a well-balanced mix of firms of different sizes, production processes, and industries. The conceptual model was tested using factor analysis, multiple linear regression analysis and univariate Anova. The results indicate that the contributions of different ERP system modules vary with different measures of changes in performance and that a holistic ERP system contributes to performance changes. The results further indicate that the contributions of CSFs vary with different measures of changes in performance and that CSFs and the holistic ERP system influences the success achieved from deployments. Also, firms that emphasize CSFs throughout the ERP implementation process achieve greater performance benefits as compared to those that focus on CSFs during the initial ERP system deployment. Overall, the results of the study support the relationships hypothesized in the conceptual model.

Para atender as novas exigências, as empresas devem buscar flexibilidade e agilidade, ou seja, devem ser capazes de se reconfigurar rapidamente a fim de atender as necessidades do consumidor final de maneira efetiva, com produtos de alto valor agregado e baixo custo. A proposta do modelo organizacional de Empresa Virtual (EV) fornece às empresas as características necessárias para competir no mercado e ir de encontro às necessidades dos clientes. A Empresa Virtual é definida como uma aliança temporária de empresas que se unem para dividir suas habilidades, competências essenciais e recursos para melhor atender uma oportunidade de negócio, sendo a cooperação entre as empresas suportada por tecnologia da informação (CAMARFNHA-MATOS e AFSARMANESH, 2005). Devido à natureza autônoma e heterogênea dos membros da EV, a manufatura do produto é realizada por empresas com formas de produção e tecnologias distintas. Isso causa problemas relacionados à qualidade dos produtos/serviços oferecidos; ao ritmo da produção; às antecipações ou atrasos da produção em relação ao tempo previamente planejado; etc., acarretando em prejuízos e até no não cumprimento dos objetivos da EV. Diante deste contexto, este trabalho propõe uma metodologia de análise que auxilie na tomada de decisão frente a problemas logísticos relacionados ao tempo de produção, buscando soluções que garantam o sucesso de operação da EV. / Abstract: Today, companies operate in markets in permanent change. In order to meet the new requirements of these markets, they must search flexibility and agility, i.e., they should be able to reconfigure quickly to attend the needs of the end consumer in an effective way, with high value added and low cost products. The purpose of the Virtual Enterprise (VE) organizational model provides the companies with the necessary characteristics to compete in the market and to meet the needs of clients. The Virtual Enterprise is defined as a temporary alliance of companies that come together to share their skills, essential competences and resources in order to better respond to a business opportunity, being this cooperation supported by information technology (CAMARINHA-MATOS and AFSARMANESH, 2005). Due to the heterogeneous and independent nature of the virtual enterprise members, the product manufacturing is made by companies with different ways of production and technologies. This causes problems related to the quality of the offered products / services; the production rate; the advances or delays in the production in relation to the previously scheduled time; etc., resulting in losses and even in noncompliance with the objectives of the virtual enterprise. In this context, this work proposes a methodology of analysis, which aids the decision making in logistical problems related to the production time, seeking solutions to ensure success in the operation of the virtual enterprise. / Mestrado / Materiais e Processos de Fabricação / Mestre em Engenharia Mecânica
