An evaluation of the implementation of Mercedes Benz production system (MPS) and the employee change readiness at Mercedes Benz commercial vehicles South Africa

McAllister, Rozane Ronardo January 2015 (has links)
The evaluation report section describes the evaluation of the implementation of Mercedes Benz Production System (MPS) at Mercedes Benz Commercial Vehicles, which is a division of Mercedes Benz South Africa’s manufacturing plant situated in East London. The section evaluates the changes the implementation of MPS brought to the Key Performance Indicators (KPI’S) of the division and evaluates the change readiness of the employees in the division prior to the change. The change implementation was initiated by the management of MBCV as a strategic organisational change to bring about continuous improvement to the KPI’s of the organisation. These KPI’s are Safety, Quality, Delivery, Cost and Morale (SQDCM). The reason behind the change at the time was deemed critical to MBCV in order to meet the annual KPI targets and remain cost competitive and sustainable. The evaluation report further describes the results of the change with regards to the organisational KPI’s and the level of employee change readiness which was conducted through a questionnaire survey. A brief literature review is included in the Evaluation Report under section one describing key concepts about Production Systems, Lean Manufacturing and Change Management. The evaluation section includes recommendations based on the results of the research findings and ends with a conclusion. The literature review section explores the literature that supports production systems, lean manufacturing and change management concepts, its definitions, importance and benefits. The literature review describes and critiques key concepts of the research such as productions systems, MPS in particular, lean manufacturing concepts and related change management topics relevant to the research. The literature review defines production systems and the concepts of lean manufacturing, highlighting the benefits of the concepts to enhance organisations’ manufacturing capabilities. An integrated part of lean manufacturing is people and the implementation of lean manufacturing into an organisation requires change management theories therefore key understanding in this particular research was to discuss change management concepts, in particular, employee change readiness. The literature will discuss different tools to assess employee change readiness and from this develop an employee change readiness tool. The change management concepts evaluated change readiness and the consequences if organisations are not ready for change. The research methodology section describes how that the research was conducted in two phases, one to evaluate the implementation of MPS with regards to the organisational KPI’s (SQDCM). This was assessed through reports from projects and presentations made by the project teams on improvements of the organisational KPI’s. The second phase evaluated the change readiness of the employees prior to the implementation of MPS. This phase of the research was intended to retrieve quantitative data with an adapted questionnaire which was distributed to employees. To evaluate the change readiness, a change model known as ADKAR was used as an evaluation instrument. The modified ADKAR questionnaire was distributed to employees in hard copies and completed during a weekly team meeting. The results were summarised and descriptive statistics were used to analyse the final results. Microsoft Excel (2010 version) was used to illustrate and display the graphs. Section three discussed the research methodology in more detail. The study shows that although there were some positive changes that came from the implementation of MPS in MBCV, especially to the following KPI’s (Safety, Quality, Delivery and Cost), real consideration should be given to employee morale and the level of change readiness of MBCV employees.

A Quantitative Evaluation of the Productivity of the Mercedes-Benz Production System

Shaw, Derrick Tajuan 01 January 2019 (has links)
Productivity of automotive manufacturing production systems have been an area of study among researchers since the industrial revolution. Automotive manufacturing production systems that are implemented properly increase productivity in production environments. Researchers have demonstrated that productivity can be improved through modeling the Toyota production system. However, researchers have not established how implementing Mercedes Benz production system (MBPS) impacted Mercedes-Benz cars' productivity between 1999 and 2017. The purpose of this quantitative research study was to examine the effect of implementing the Mercedes-Benz Production System (MBPS). A survey was administered to 35 Mercedes-Benz employees that consisted of operation managers, plant managers, manufacturing engineers, and shop workers. The study used Spearman's correlations to analyze the strength of the associations between the dependent variable of productivity and the three independent variables of cycle-time variation, employee-headcount variation, and key performance indicators. The results showed no statistically significant relationship, supporting that implementing the MBPS was not sufficient enough to reject the null hypothesis the research questions. The social change implications for this research may promote positive social change by its emphasis on the implementation of manufacturing production systems. Such implementations may then stimulate increased economic efficiencies, quality, and profitability for society.

Unfolding Diagrams As Generative Design Tools In Architectural Design Process:united Network (un) Studio-mobius House / Arnhem Central Station / Mercedes Benz Museum

Kuyumcu, Basak 01 September 2010 (has links) (PDF)
The aim of this thesis is to explore the role of the diagrams as generative design tools in architectural design process. Identifying the utilization of the diagrams as infrastructural and organizational elements in the design process, it aims to be concentrate on their potency for generating novel design concepts. The search has been for the possibilities of design processes developed and manipulated not through analytical use of diagrams that represents the already established relationships but through their generative use that is responsible for the proliferation of ideas for novel design concepts. The alteration in the definition of diagrams, their active role in the generation of design ideas, and their progression during the design process, as well as the ways in which they contribute to the delay of formal concerns through the practice are scrutinized. In order to explore the generative and mediating roles of diagrams in architectural design practice, this thesis examines the utilization of diagrams by exemplifying the strategies of UN Studio. Through exploration of their pioneering projects, the M&ouml / bius House, the Arnhem Central Station and the Mercedes Benz Museum, it aims to unfold their design methods regarding diagrams. Diagrams are examined in terms of the way they are utilized and operated from conceptualization to building. While standing at a critical distance, it argues for an architectural design process where design ideas are formed and evolved by utilization of diagrams as generative tools from the initial phases of the design to the actualization of the building.

No. of bitstreams: 1 Eduardo Magalhaes Rodrigues.pdf: 1135925 bytes, checksum: 453b21c09c753046d5b47bf1bb5d1878 (MD5) Previous issue date: 2013-05-23 / The present dissertation is focused on the experience of the international trade union organization of workers since MBB in SBC. I highlight "since" because the very nature of the process led to the global connection with employees located at industrial units in foreigner countries of the same transnational company. Among several political players as well as in the academic world, there is the controversial issue about the importance of the union movement not only in Brazil, but also internationally. In other words, the main issue is about the effectiveness of international trade unionism in the presence of the capital hegemonic globalization. On one hand concerns if it is possible that this practice means an alternative to the hegemonic model, even being, nowadays, in an incipient stage. On the other hand if the international trade union perspective can contribute to the maintenance or new achievements of the workers. Such issues are strongly important, mainly in a world of intense and growing globalization of all sectors of society. There was an indication of positive responses to both questions above, suggesting that, despite the current worldwide crisis, involving the international trade union movement as well, is an feasible strategy and even essential to the worker. The methodology, besides the theoretical references, dealt with field research collecting primary data and interviews with the main protagonists of the international trajectory, which completes 30 years in 2014 / A presente dissertação analisa a experiência de organização sindical internacional a partir dos trabalhadores na Mercedes-Benz do Brasil na cidade de São Bernardo do Campo. Digo a partir , pois a própria natureza do processo levou à conexão global com os trabalhadores localizados em unidades de outros países da mesma transnacional. Há, entre os atores políticos mais diversos, bem como no mundo acadêmico, a controversa questão sobre a importância do movimento sindical não só no Brasil, mas também em nível internacional. Isto é, contesta-se a respeito da efetividade do sindicalismo internacional diante a globalização hegemônica do capital. Uma questão diz respeito se as práticas adotadas, mesmo que ainda incipientes, significam uma futura alternativa ao modelo hegemônico. Outra trata se a perspectiva internacional sindical em curso pode contribuir para a manutenção ou novas conquistas para os trabalhadores. Tais questões são vitais, especialmente em um mundo de intensa e ainda crescente globalização em todos os setores sociais. Evidenciou-se a indicação de respostas positivas às dúvidas acima, sugerindo que, não obstante a crise atual, também, do movimento sindical internacional, trata-se de uma estratégia exequível e mesmo indispensável ao trabalhador. A metodologia seguida, além das referências teóricas, lançou mão, basicamente, da pesquisa de campo por meio do estudo de fontes primárias e entrevistas junto aos principais protagonistas da trajetória internacional que em 2014 completa 30 anos

No estudo, o NbCl5 s?lido foi utilizado como reagente, e nos outros m?todos foi empregado um catalisador de ni?bio enxertado em s?lica e um catalisador de grupos sulf?nicos imobilizado em s?lica. Nos processos heterog?neos a SiO2 (507 m2g-1, ?rea espec?fica) utilizada como suporte dos catalisadores, foi produzida a partir de areia constru??o e carbonato. O NbCl5 e os grupos ?SO3H foram imobilizados diretamente ? temperatura ambiente na SiO2, formando respectivamente o SiO2-Nb, com 412 m2g-1 de ?rea espec?fica e o SiO2-SO3H, com 115 m2g-1 de ?rea espec?fica. Nas esterifica??es utilizando NbCl5 s?lido foi determinado que para a obten??o de rendimentos razo?veis de ?steres de benz?licos (>85%) e ?steres met?licos (>70%) em rea??es a temperatura ambiente, a propor??o m?nima em moles de NbCl5:?lcool benz?lico deve ser 1,5:1,0 e para obten??o dos ?steres met?licos a propor??o de 1,5:6,0. Nas metodologias aplicando os catalisadores heterog?neos foi utilizada uma quantidade de 7% (m/m) do catalisador SiO2-SO3H para catalisar a esterifica??o de diferentes ?cidos carbox?licos com ?lcool benz?lico. E para as mesmas rea??es com o catalisador SiO2-Nb foi utilizada uma raz?o de 10% (m/m) do catalisador. Ambos os processos foram realizados sob refluxo na aus?ncia de um solvente; rendimentos muito semelhantes foram obtidos apesar do catalisador SiO2-SO3H possuir uma ?rea superficial muito menor que o catalisador SiO2-Nb. / Disserta??o (Mestrado) ? Programa de P?s-gradua??o em Biocombust?veis, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / The current work describes the study of new methodologies for obtaining benzyl esters and methyl esters of fatty acids (biodiesel) using solid NbCl5 and heterogeneous acid catalysts. In this study, solid NbCl5 was used as a reagent, and in the other methods a silica grafted niobium catalyst and a sulphonic group catalyst immobilized on silica were used. In the heterogeneous processes the SiO2 (507 m2g-1, specific area) used as support of the catalysts, was produced from sand building and carbonate. The NbCl5 and the -SO3H groups were directly immobilized at room temperature in SiO2, forming respectively SiO2-Nb, with 412 m2g-1 of specific area and SiO2 -SO3H, with 115 m2g-1 of specific area. In the esterifications using solid NbCl5 it was determined that in order to obtain reasonable yields of benzyl esters (>85%) and methyl esters (>70%) in reactions at room temperature, the minimum mole ratio of NbCl5/benzyl alcohol should be 1,5:1,0 and in the obtainment of the methyl esters at a ratio of 1,5:6,0. In the methodologies applying the heterogeneous catalysts to an amount of 7% (w/w) of the catalyst SiO2 -SO3H to catalyze an esterification of different carboxylic acids with benzyl alcohol. Both processes were performed under reflux in the absence of a solvent; very similar yields were obtained although the SiO2-SO3H catalyst had a much lower surface area than the SiO2-Nb catalyst.
