Internal Performance Benchmark : -Cost Gap Analysis between painting processes / Intern Prestandajämförelse : - Kostnadsanalys mellan två måleriprocesser

Rosell Sagrelius, Simon January 2018 (has links)
Scania OmniExpress Busproduction Finland Oy in Lahti, a company that manufactures buses of product family Scania Interlink LD, Scania Interlink MD, Scania Interlink HD and Scania Citywide LE Suburban. As Scania receives larger customer orders, these orders are divided into both Scania Production Słupsk S.A. and Scania OmniExpress Busproduction Finland Oy, which bring a desire to harmonize these factories. To achieve this harmonization an investigation is required of Scania OmniExpress Busproduction Finland Oy analysis process and comparison with Scania Production Słupsk S.A. To keep up the permanent development outcome, Strategic Plan Scania Production Lahti requires a survey of the painting process in Lahti, Finland. Based on this, an internal cost performance benchmark has been implemented between the factories. Through a currant status analysis of both facility’s, based on Strategic Plan Scania Production Lahti methods and strategies, as well as complementing this with external methods and theory, the gap between the factories has been conducted from a cost perspective. Based on the more in-depth analysis made in Scania OmniExpress Busproduction Finland Oy, an improvement work has been carried out. / Scania OmniExpress Busproduction Finland Oy i Lahti, tillverkar idag bussfamiljerna Scania Interlink LD, Scania Interlink MD, Scania Interlink HD och Scania Citywide LE Suburban. För att kunna leverera vid större kundordrar delas dessa upp mellan två Scaniaägda fabriker, Scania Production Słupsk S.A. och Scania OmniExpress Busproduction Finland Oy, detta medför att en harmonisering krävs mellan fabrikerna så att slutprodukten blir identisk. För att uppnå denna harmonisering utfördes denna studie mellan dessa fabriker. Att jobba med ständiga förbättringar är djupt inprintat i Scanias visioner och mål. I arbetet med ständiga förbättringar för processer skulle målerprocessen förbättras i denna studie. Genom en nulägesanalys i båda fabrikerna baserad på Strategic Plan Scania Production Lahti metoder och strategier såväl som kompliment från externa metoder och teorier har prestanda gapet identifierats. Baserat på en såväl djupare nulägesanalys i Scania OmniExpress Busproduction Finland Oy, har ett förbättringsarbete utförts.

Para tanto, há diversas formas de descobrir os fatores críticos de competitividade que podem estar presentes nos mais diversos setores de manufatura. Logo, o uso de técnicas robustas para avaliar e medir esses fatores torna-se essencial para o suporte à tomada de decisão. Este estudo tem o objetivo de analisar a influência dos processos de melhoria contínua e de aprendizado em termos de eficiência e volume de produção em uma empresa de manufatura. Para atingir o objetivo proposto, a pesquisa realiza um estudo de caso utilizando a Análise Envoltória de Dados (DEA), combinada com o teste de Regressão Linear e o teste de ANOVA. Nesta etapa, formula-se um modelo conceitual com quatro hipóteses principais e oito hipóteses secundárias. Para avaliação da eficiência DEA, o modelo utiliza retornos variáveis de escala (VSR) com orientação a insumo, considerando as principais matérias-primas utilizadas pela empresa com base no custo variável total. O teste de Regressão Linear efetua a avaliação do impacto do processo de melhoria e de aprendizado na eficiência (DEA). Por sua vez, o teste de ANOVA avalia as médias da eficiência de cada linha de produção para cada ano analisado. O estudo realiza-se de forma longitudinal, com avaliação de seis anos de produção de manufatura. Os resultados da pesquisa mostram que apenas uma das linhas de produção aumentou a eficiência ao longo do tempo. Além disso, indicam que duas linhas de produção tiveram impacto das ações de melhoria no volume de produção. Logo, as variáveis referentes aos programas de Kaizen, às horas de treinamento e à experiência dos funcionários influenciaram significativamente o modelo. Verifica-se que os projetos voltados à melhoria contínua e ao aprendizado não foram suficientes para aumentar a eficiência em duas importantes linhas de produção. Além disso, o estudo elucida que o volume de produção impacta negativamente a eficiência de uma das linhas de produção. Com a análise, é possível identificar quais fatores são representativos para aumentar a eficiência produtiva. Logo, conclui-se que a atualização tecnológica constitui um fator importante a ser seguido pela empresa estudada. / Everyday, companies seek to improve their productive efficiency and, thus, increase their profitability and competitiveness. For both, there are several ways to discover the critical factors of competitiveness that may be present in various manufacturing sectors. Thus, the use of robust techniques to assess and measure these factors is essential to support decision making. This study aims to analyze the influence of the processes of continuous improvement and learning in terms of efficiency and production volume in a manufacturing company. To achieve the proposed objective, the research conducts a case study using Data Envelopment Analysis (DEA), combined with the Linear Regression test and the ANOVA test. At this stage, a conceptual model with four main hypotheses and eight secondary ones is formulated. To evaluate the DEA efficiency, the model uses Variable Scale Returns (VSR) with input orientation considering the main raw materials used by the company based on the total variable cost. The Linear Regression test performs the evaluation of the impact of the improvement process and learning efficiency (DEA). In turn, the ANOVA test evaluates the average efficiency of each production line for each year analyzed. The study is carried out longitudinally, by reviewing six years of manufacturing. The survey results show that only one of the production lines increased efficiency over time. In addition, the results indicate that two production lines have been impacted by the actions of improvement in the volume of production. Therefore, the variables related to Kaizen programs, to the hours of training and to employees ́ experience significantly influenced the model. It can be concluded that the projects focused on continuous improvement and learning were not sufficient to increase efficiency in two major production lines. Furthermore, the study shows that the production volume negatively impacts the efficiency of the production lines. With the analysis, it is possible to identify which factors are representative to increase production efficiency. Therefore, it can be conclude that the technology upgrade is an important factor to be followed by the company studied.
