Discussion of the gradual progress of automobile industry - take the United States , Japan and Germany as an example

Lin, Yun-tiao 29 August 2006 (has links)
The nature of range ¡§ automobile ¡§ has high technology and traditional science both together. It expands living habit and areas for the human beings but also lead hazard and risky on environment and safety. What is the value of competition about the automobile? What are the cons and pros on traditional manufactures with United States, Japan and Germany? Any structure change from then until now? The subject essay is based upon the automobile research report, which was issued on 1990 by MIT, analysis of GM with The United States, Toyota with Japan and Volkswagen with the Germany 1991-2005 financial statements and volume production strategy to continue the analysis. The automobile manufactures were following the model of productions TPS after MIT research report was announced. The above companies were not being able to follow and copy the model very successfully. Because that past successful enterprise cultural was difficult to abandon and among different countries cultural background and basis were total different and individual. They could only practice the fur of Japanese Toyota. For example, GM was combined with Toyota to build up factory as issue; looks like GM have had good flow and function on inventory turn over percentage and cost of sales volume. After operation factors were getting worse even turn their inefficiency out to the fact. The traditional craftsman¡¦s art with Germany were become the sign of obstacle to the TPS.

Análise e aplicação de métodos de modularização no desenvolvimento do produto /

Ramos, Cesar Coutinho. January 2016 (has links)
Orientador: Antônio Wagner Forti / Banca: Bruno Chaves Franco / Banca: Carlos Alberto Chaves / Resumo: Este trabalho compara qualitativamente sete métodos de modularização, com o objetivo de escolher e aplicar aqueles que melhor se adaptam ao projeto piloto de modularização de uma suspensão traseira a ar para caminhões e ônibus. Dentre os métodos estudados, os métodos MFD (Modular Function Deployment) e DSM (Design Structure Matrix) foram escolhidos, basicamente em função de possuírem: aplicação prática, repetibilidade dos resultados, softwares disponíveis e facilidade de organização dos dados. O método DSM serviu de base para gerar os primeiros possíveis módulos e simplificar o problema dos inicias 44 componentes para 26, simplesmente com uma visão funcional e técnica. O MFD foi utilizado principalmente para estruturar o processo de modularização e atender aos requisitos dos clientes e estratégias do negócio. Os resultados apresentados pelos dois métodos foram analisados de forma detalhada e indicaram a formação de sete módulos, que foram obtidos tanto diretamente dos métodos DSM e MFD, quanto da combinação de ambos. Ficou evidente, através dos resultados alcançados, que a utilização conjunta desses dois métodos, juntamente com a análise criteriosa dos resultados no desenvolvimento do produto aumentou consideravelmente a eficiência do processo de modularização / Abstract: This work presents and compares qualitatively seven modularization methods, in order to choose and apply those that best suits for a rear air suspension modularization pilot project for trucks and buses. Among the methods studied, the MFD (Modular Function Deployment) and DSM (Design Structure Matrix) methods were mainly chosen on the basis that they present: practical application, repeatability, software availability and ease data organization. The DSM method was the basis to generate the first possible modules and simplify the problem from the initial 44 to 26 components, only with a functional and technical approach. The MFD was mainly used to structure the modularization process and meet the customer requirements and business strategies. The results shown by the two methods were analyzed in detail and resulted in the generation of seven modules, which were obtained either directly from DSM and MFD methods, or from the combination of both. It became evident, by the results achieved, that the combined use of these two methods, along with a careful analysis of the results on product development, greatly increased the modularization process efficiency / Mestre

Ana Claudia Tassi Amancio 22 September 2016 (has links)
A atual pesquisa faz parte do grupo de pesquisa, cadastrado no Conselho Nacional de Desenvolvimento Científico e Tecnológico, sobre moda na cadeia têxtil, tendo como foco as questões sociais da cadeia produtiva da manufatura do vestuário de moda. O mercado de produto de vestuário de moda massificado enfrenta grandes dificuldades com consumidores que desejam produtos personalizados e serviços rápidos, eficientes e, ao mesmo tempo, conforme suas necessidades. Cada vez mais as empresas do setor de vestuário necessitam de gestões eficientes a partir de novas estratégias alinhadas com as novas tecnologias visando o desenvolvimento, a produção e a comercialização do produto com o objetivo de atender a demanda do mercado consumidor. As empresas que apostam nesses produtos personalizados estão descobrindo que as soluções convencionais poderão ser extintas e que há necessidades de novas práticas para estarem aptos a desenvolver os produtos e serviços que atendam às necessidades e aos desejos dos seus consumidores. O processo de diferenciação e personalização na manufatura do vestuário da moda ocorre de forma cada vez mais acelerada. Neste contexto, a indústria em seu processo de desenvolvimento de novos produtos se antecipa buscando descobrir tendências, a fim de produzir de forma otimizada e atender a demanda de consumidores específicos que desejam ser percebidos de forma cada vez mais individualizada. Esta pesquisa tem como objetivo geral estudar a diferenciação e personalização da produção através da customização em massa, atendendo a demanda de um determinado público-alvo. Em relação aos procedimentos metodológicos, foram realizadas pesquisas bibliográficas que resultaram na fundamentação teórica, a qual auxiliou na construção dos questionários com perguntas semiestruturas, a serem aplicadas nos estudos de casos com empresas que utilizam estratégias de diferenciação do produto, através da customização em massa. Após, foi possível analisar os casos, bem como comparar por meio de quadros, as estratégias e processos utilizados pelas por estas empresas. Os resultados permitiram confirmar quais estratégias e processos são necessários para prática efetiva do produto diferenciado e personalizado através da customização em massa. Portanto, este estudo se justifica pela importância social e econômica do setor têxtil e da moda e pela escassez de bibliografia acerca do tema. Espera-se assim que essa pesquisa possa lançar luz em um campo pouco pesquisado, além contribuir com referencial bibliográfico / The present research is part of the research group, registered with the National Council for Scientific and Technological Development, on fashion in the textile chain, focusing on social issues of the productive chain of manufacture of fashion apparel. The massiveness fashion apparel product market faces great difficulties with consumers who want customized products and fast, efficient and at the same time, as needed. More and more clothing sector firms need efficient efforts from new strategies aligned with new technologies for the development, production and marketing of the product in order to meet the demand of the consumer market. The companies that invest in these customized products are finding that conventional solutions may be extinct and that there is need for new practices to be able to develop products and services that meet the needs and desires of its consumers. The differentiation and customization process in the fashion garment manufacturing is increasingly accelerated rate. In this context, the industry in the development process of new products anticipates seeking to discover trends in order to produce optimally and meet the demand for specific consumers who wish to be perceived increasingly individualized. This research has the general objective to study the differentiation and customization of production through mass customization, meeting the demand of a targeted audience. Regarding the methodological procedures were conducted literature searches that resulted in the theoretical foundation, which helped build the questionnaires with semi-structured questions, to be applied in the case studies with companies using product differentiation strategies through mass customization. After it was possible to analyze the cases and compare through frameworks, strategies and processes used by these companies. The results confirm what strategies and processes are needed for effective practice of differentiated and personalized product through mass customization. Therefore, this study is justified by the social and economic importance of the textile sector and fashion and the lack of literature on the subject. It is hoped that this research will shed light on a little-researched field, besides contributing to bibliographic references

Produção do fungo entomopatogênico Metarhizium rileyi (Farlow) por fermentação líquida e sólida / Production of the entomopathogenic fungus Metarhizium rileyi (Farlow) by liquid and solid fermentation

Kauana Abati 06 October 2015 (has links)
Metarhizium rileyi é um importante fungo patogênico a várias espécies de pragas desfolhadoras da família Noctuidae. Existe uma grande demanda para a produção em escala deste fungo, mas ainda não há produtos comerciais no mercado brasileiro. Os objetivos do presente estudo foram avaliar a produção de conídios de M. rileyi por fermentação sólida usando diferentes grãos e cereais e a produção de blastosporos por fermentação líquida em meios com diferentes fontes de carbono e nitrogênio. Na produção de conídios em substrato sólido, foi empregado o isolado ESALQ 1305 em oito tratamentos com grãos/cereais incubados por 15 dias. Para os experimentos de produção de blastosporos em substrato líquido, foram conduzidos quatro experimentos sequenciais onde foram testados diferentes meios e concentrações de células oriundas do pré-cultivo e diferentes fontes e concentrações de carbono, nitrogênio, relação C:N e tempo de cultivo. Os dados foram submetidos a análise de variância e as médias comparadas pelo teste de Tukey a 5%. Os substratos sólidos que resultaram em maior produção de conídios foram o feijão fradinho moído sem peneirar (7,4 ± 2,8 x 108 conídios.g-1) e trigo moído peneirado (3,3 ± 1,2 x 108 conídios.g-1). Nos experimentos de fermentação líquida a 300 R.P.M e 25 °C observou-se que os meios desenvolvidos por Jaronski e Jackson (2012) com relação C:N de 50:1, proporcionam as maiores concentrações de blastosporos de M. rileyi. Os melhores resultados foram obtidos no último experimento com o isolado ESALQ 1305 quando o pré-cultivo foi realizado com meio contendo 36 g.L-1 de concentração de carbono e relação C:N de 50:1, posteriormente inoculado na razão de 105 blastosporos.mL-1 nos meios de cultivo contendo 40 g.L-1 e 80 g.L-1 de carbono, tendo extrato de levedura como fonte proteica, obtendo-se concentrações de 3,6 ± 1,6 x 109 blastosporos.mL-1 e 4,0 ± 0,6 x 109 blastosporos.mL-1, respectivamente, após quatro dias. Os resultados demonstram a viabilidade da produção de blastosporos de M. rileyi, por fermentação líquida. / Metarhizium rileyi is an important fungus pathogenic to various species of defoliating pests of the family Noctuidae. There is a great demand for mass production of this fungus, but there is still no commercial products in the Brazilian market. The objectives of this study were to evaluate the conidial production of M. rileyi by solid fermentation using different grains and cereals and the production of blastospores by liquid fermentation in media with different sources of carbon and nitrogen. In the production of conidia in solid substrate, the isolated ESALQ 1305 was used in eight treatments with grains/cereals incubated for 15 days. For the production of blastospores in liquid substrate, four sequential experiments were conducted using different media, concentrations of pre-cultivation, sources of carbon, nitrogen, C:N ratio and cultivation time where tested. Data were analyzed by the use of ANOVA and post hoc comparisons of means using the Tukey\'s test to 5%. The solid substrates resulting in higher production of conidia were black-eyed beans milled without sieving (7.4 ± 2.8 x 108 conidia.g-1) and wheat milled and sieved (3.3 ± 1.2 x 108 conidia.g-1). In the liquid fermentation experiments to 300 R.P.M. and 25 °C it was observed that the media developed by Jaronski and Jackson (2012) with C:N ratio of 50:1, provides the greatest concentration of blastospores of M. rileyi. The best results were obtained in the last experiment with the isolate ESALQ 1305, when the pre-cultivation was conducted in media containing concentration of carbon of 36 g.L-1 and C:N ratio of 50:1, inoculated in the ratio of 105 blastosporos.mL-1 in culture media containing 40 g.L-1 and 80 g.L-1 of carbon, using yeast extract as protein source, obtaining the concentrations of 3.6 ± 1.6 x 109 blastospores.mL-1 and 4.0 ± 0.6 x 109 blastospores.mL-1, respectively, after four days. The results demonstrate the viability of high-yield production of blastospores of M. rileyi by liquid fermentation.

Entry mode selection of multinational enterprises entering high risk countries in sub-Saharan Africa

Van Coller, Sunel January 2016 (has links)
Throughout the years, different theories and models have been developed regarding multi-national enterprises' (MNEs') entry into foreign markets. One such model is the Organisational Model, identifying three different types of enterprise, each selecting a different mode of market entry during foreign market expansion. These are: massproduction enterprises, disaggregate-production enterprises and project-based enterprises. This model was based on studies focusing mainly on the US, Europe and Asia. Research indicates, however, that MNEs increasingly identify sub-Saharan Africa (SSA) as a region for possible expansion. In view of persistent risk within the SSA region, this study's focus is on determining which entry modes MNEs use when entering a perceived high-risk market in SSA. This research study focused on MNEs that have expanded or are currently expanding into a perceived high-risk country in SSA. A qualitative research design was selected, applying an in-depth case study analysis to six different MNEs two MNEs representing each type of enterprise as categorised by the Organisational Model. Semi-structured personal interviews were conducted with each participant. Each interview focused on elements relating to the MNE's perception of, and approach to selecting entry mode into, high-risk markets. Findings predominantly did not find support for the Organisational Model, indicating that MNEs entering perceived high-risk markets in SSA preferred different entry mode strategies and approached risk consideration differently. Some findings did confirm the literature, by indicating that MNEs consider country risk when entering a foreign market in SSA. / Dissertation (MCom)--University of Pretoria, 2016. / Business Management / MCom / Unrestricted

Initiating transformation towards AI in SMEs

Rönnberg, Hanna, Areback, Jenny January 2020 (has links)
Purpose – The purpose is to explore how SMEs can initiate transformation towards AI. The purpose will be fulfilled through identifying which opportunities that exist for SMEs and which challenges they are facing. Additionally, we will identify which requirements are necessary to face these challenges. Method – A qualitative approach was most suitable for this study since the purpose is to explore how SMEs can initiate transformation towards AI. It was also suitable since we have collected data through interviews. We have done a single case study where we have studied one supply chain. Finally, we have had an inductive research approach which means that we have gathered a theoretical background which has founded the base and the background for our study, but our interviews have founded the result of the study and created a conclusion based on that. Findings –The result of the study provides identified opportunities with AI for SMEs, what challenges can occur, and which requirements that are needed to face the challenges. The opportunities are identified as forecasting, maintenance and repair, self-optimization, and tracing and tracking. The identified challenges when initiating transformation towards AI are cultural difficulties, lack of external communication, lack of internal communication, limited internal processes, and lack of resources. The requirements are identified as automation, data, strategy, and capabilities. The opportunities, challenges and requirements are summarized in a framework. Theoretical and Managerial Implications – We have contributed to literature by exploring how an SME, as a mass production company, can benefit from AI by identifying opportunities, challenges, and requirements. Additionally, the framework guides SMEs to prepare for opportunities with AI and ensure that they have all of the requirements. Further, by understanding which requirements that are necessary for a transformation and which challenges that can occur, managers can reduce risk of failing projects. Limitations and Future Research –The number of studied companies together with that the study is a single case study limits the generalizability. It creates a suggestion for future research where a wider set of data can be collected. Additionally, we have identified challenges that can occur, however how companies should face these challenges in the best way is a suggestion for future research.
