In the LCD display products source section LED light display product is OK to replace the traditional CCFL light display products, especially in the NB computer and computer monitor are almost over two to three years CCFL products will be completely out of the market. The LCD itself does not glow and need another light source to support it. Backlight module can provide light source to LCD display product. In the early the light source of backlight module is CCFL. But LED light source is going to replace CCFL from 2007. Most of all new developments in the field of the NB computer backlight module changes light source from CCFL to LED. Even the computer monitor light source is starting to use LED too. The development technologies and production quality of the LED backlight module are significant challenges in LED backlight module factory. The purpose of this study was to identify development technologies and production technologies factors of bottlenecks, and finding a solution. And can provide some help to LED backlight module industry terms. This study selects ' 8D process ' to be analysis model. And collect 5 backlight module factories development experience and production status data. Hope these data through 8D analysis process can find the major related factors of development technologies and production technologies. In-depth research, look forward to finding out the production technologies relevant factors oppression ' technical specification ' production. This study is expected to be able to find some effect LED backlight module process yield factor, then apply the stratification out product issues and process issues, this study is intended for process issue do take an in-depth look at the problem and solution, but about product issue will be' design solutions ' way to describe. I believe this research can help LED backlight module industry to reduce production cost and improve the development speed.

Quality tools Ishikawa, Taguchi, fall into this prospect of improvement, and can evaluate the applicability of these tools in a medium-sized industry, producer of paper packaging. Through its application, aims to remove some of the losses existing in the process, improving their productivity and the quality of the final product. Application of Taguchi aims to evaluate the best settings and patterns of operation of the equipment to meet the demands of consumers, owners and employees of the company. / No presente trabalho realizou-se um estudo do sistema troca rápida de ferramenta, método Taguchi, sistema Toyota, método Ishikawa, para minimizar ou resolver problemas envolvidos na produção, em específico, em indústria de embalagem de papel, motivado pela necessidade de melhorar o sistema produtivo da empresa, com vistas a reduzir as perdas de matéria prima e também os custos da produção. As ferramentas de qualidade Ishikawa, método Taguchi, enquadram-se nessa perspectiva de melhoria, e pode-se avaliar a aplicabilidade destas ferramentas em uma indústria de médio porte, produtora de embalagens de papel. Através da sua aplicação, pretende-se eliminar algumas das perdas existentes no processo, melhorando sua produtividade e a qualidade do produto final. A aplicação do Taguchi tem como objetivo avaliar as melhores regulagens e padrões de operação do equipamento para atender às exigências dos consumidores, proprietários e colaboradores da empresa.

In today’s market it is possible to get a competitive advantage with right quality- and safety work to satisfy the customers in the automotive- and manufacturing industry. Today companies are also highly exposed with today’s media and social media which make the quality assurance even more important to avoid bad publicity. This report consists of an investigation about how the automotive- and manufacturing industry work with their suppliers’ to mutually achieve the required quality targets. Toyota Motor Corporation has single handily been a trademark for high quality for a long time in the automotive industry. Their successful organization is based on different principles which have created The Toyota Way. Thus the authors’ of this report has chosen to select some of these principles, which are thought to be appropriate for the reports purpose. The principles are investigated and described so that they can be compared to the case study at Volvo Cars Torslanda. The purpose is to find potential improvement possibilities and recommendations for both Volvo Cars and for the manufacturing industry. The findings and analysis has shown that a more cross-functional way of working in teams between different departments should be used in a greater extension. Thus to achieve greater knowledge in the decision making process concerning the organization and to improve the quality assurance work concerning the suppliers’. Another recommendation is to greater encourage job rotations among the quality engineers concerning the different quality reviews. The authors’ are sure that greater job rotation can encourage better motivation at work and support to become an even more learning organization in addition to achieve the greater quality assurance. With these findings and recommendations the authors’ believe and suggests that further research can be done with a deeper approach towards the specific recommendations to find further improvement possibilities concerning the automotive- and manufacturing industry.

This diploma thesis focusses on quality management system settings in accordance with the international standard ISO/TS 16949 in the conditions of a medium-sized enterprise, a supplier for the automotive industry. The theoretical part of the thesis is based on professional literature, including professional articles, and describes individual theoretical outcomes, which are subsequently applied in the practical part. The practical part of the thesis concentrates on the project of the implementation of this standard into the structure of medium-sized enterprises. Furthermore, the thesis evaluates financial and temporal difficulties with regard to the introduction of certification. It also provides an analysis of key processes, proposes a process map and offers a risk analysis via the method FMEA as well as an assessment of individual tools of quality management. Overall, the thesis provides a holistic overview of the issue concerning the implementation of quality management system in the conditions of the supplier for the automotive industry.

This document undertakes a practical study to measure the effectiveness of the Lean Service Quality (LSQ) model, which combines the development of a multi-elemental scale to measure service quality (SERVQUAL) and a conceptual/practical Lean Service model, with the aim of reducing the number of poorly performed technical repairs at a Toyota automobile dealership. The main result of the research was defining a practical guide to replicate the LSQ model. In addition, as the model’s first approach, the study demonstrated that, for the dealership under study, the rate of bad repairs was ultimately reduced by 5.17%.

The Paper is focused on risk analysis of composite bumper Arway S production process. The bumper is produced by Composite Components company for Iveco bus producer. According to discussions of expert team, several types of quality discrepancies were discovered. By using FTA analysis we discovered causes of those discrepancies. FMEA method and Pareto Analysis helped to set most dangerous discrepancies which cumulative seriousness reached 54 %. In discussion, the expert team set corrective action. In parallel with FMEA and Pareto Analysis 8D method was used. It's results were in line with other methods and complete the whole image of the issue. Arway S is a key product and so some of those proposed corrective actions were realized immediately. As a result, the appearance of rejections with specific defect almost vanished.

The thesis deals with a proposal to change the production process by eliminating the redundant control activities. The first part of the thesis presents various possible theoretical approaches for this issue. It is followed by familiarisation with the concerned production company. The second part is the analytical part where the carried out activities of a particular automotive production unit are identified. These control activities are investigated and then either omitted or authorized. Finally the root causes for the fact that those activities have not already been eliminated are found.
