Para isso, utilizam muitas ferramentas de gestão, muitas delas de origem japonesas, como o Mapeamento do Fluxo de Valor (MFV) e o sistema kanban. Este trabalho tem o objetivo de descrever e classificar os sistemas de produção, os tipos de processos produtivos e de leiaute, apresentar a ferramenta MFV e o sistema kanban e, realizando um estudo de caso, apresentar a aplicação destas ferramentas na prática, de forma a facilitar a utilização das mesmas por gestores. O estudo apresenta uma fábrica com sistema tradicional de produção, um processo em lotes e um leiaute misto, englobando o leiaute funcional e células lineares e funcionais. Foram calculados, para a empresa estudada, um lead time de 68,59 dias, um tempo de processamento de 0,92 segundo, um takt time de 0,66 segundo e uma eficiência de fluxo de 1,78 x 10-5%. Com o desenvolvimento de um de fluxo de valor futuro, obteve-se a redução do lead time para 15,64 dias e o aumento da eficiência de fluxo para 7,84 x 10-5%, o que representa uma melhoria de 338%. O presente trabalho descreve a adaptação da teoria do sistema kanban à prática, apresentando o cálculo utilizado para definição do número de kanbans de produção, o design estabelecido para o cartão, a definição do quadro porta-kanban e o funcionamento do sistema. A pesquisa apresenta as dificuldades encontradas para a realização do MFV e do sistema kanban, pela escassez e dificuldade de levantamento dos dados de produção necessários e mostra a possibilidade de adaptação da teoria à prática, assim como a importância dos profissionais conhecerem as teorias das ferramentas de gestão para melhor aproveitarem o que elas têm a oferecer

This master thesis provides a relatively detailed description of the consonant-vowel structure of standard spoken Czech. The first part covers approaches to and findings on the combinatorial system and distribution of sound units in speech; aspects of continuous speech segmentation into intonation phrases and stress groups, phonotactics of languages in general and Czech in particular, and speech rhythm are also addressed. Recordings of 12 professional speakers of Czech - comprising 6639 words and 5368 stress groups in total - have been used to create data sets that have enabled the author to describe CVCV structures of Czech words and stress groups. The results of this research present frequencies of words and stress groups and their relations to word-class dimension, frequencies of phones in words and stress groups; in this respect, both syllabic liquids and glottal stops have been taken into account. Further, the thesis includes an overview of the most frequent CVCV patterns in words and stress groups and their variability with regard to word classes. The final part focuses on how frequently consonants, vowels and their pairs and trios occur at different places within a unit. The results are continuously compared both between themselves and with the research that used the larger SYN2005 written...

The major objective of present study is to find out the sources which cause higher Work in Process (WIP) in the production line. In which a detailed analysis is performed in the area of inventory, reorder point, Takt time, and Kanban. All the analyses are based on the data obtained from the company’s ERP system and have been used to run some scenarios during the analysis.Lots of problems are responsible to cause higher WIP. But current report only focuses and concentrates in leveling the work load, implementing pull system, suggesting reorder point and Takt time.The current situation is described through Value-stream Map (VSM) and the impact cost matrix is used to show the impact of each problem in the production line in terms of costs. In the analysis chapter, root cause method has been used in order to show the cause and effect of higher WIP. Detailed analyses together with explanations are listed by orders. Therefore, three major suggestions are proposed and the future VSM is plotted to show the effect and change of the suggestions which helps to improve the current situation by eliminating the waste.

As the effort of today’s industries to continuously move towards lean production, pull production system has been developed as one possible solution of lean. It is popularly known in the industry world, and is indeed a proven technique to achieve substantial savings on inventory, production cost incurred by manufactures all over the world. However, a careful understanding of pull production systems is required to access its suitability to a particular production setup. It is necessary to develop a proper way to implement pull production systems.             This study is based on a real life scenario in a leading driveline manufacturing company. The production system is studied in detail as regard to its production characteristic. A theoretical review is first made as research foundation. A careful analysis study within the company is conducted with all the existing constrains to figure out improvement opportunities. Eventually, from the applicability point of view, proposals of future pull production system implementation have been developed. The objective of the proposals is to minimize the identified weaknesses of the current system, including long lead time, low flexibility and unconnected flow.

Syftet med arbetet är att undersöka pianolärares arbetssätt beträffande puls, takt och rytm i sin undervisning samt att undersöka eventuella samband mellan dessa arbetssätt, lärarens genrebakgrund och undervisningens sociala organiseringsform. Den litteratur som presenteras i områdesorienteringen inkluderar förslag på arbetssätt som kan användas i instrumentalundervisning för att arbeta med dessa aspekter. Som metod för studien har en webbenkät skickats ut, där frågorna om arbetsmetoder utgår från de metoder som presenteras i områdesorienteringen. I resultatet redovisas analyserna av svaren på enkätfrågorna, som sammanlagt 30 respondenter besvarade. Generellt sett används de föreslagna arbetssätten i låg utsträckning. Ett samband mellan social organiseringsform och arbetet med puls upptäcktes, som visar att lärare med individuell undervisning enligt föreliggande studie arbetar med puls i högre utsträckning än de lärare vars elever får både individuell undervisning och gruppundervisning. I diskussionen lyfts sex teman, Puls, Takt, Rytm, Pianolärares arbete med puls, takt och rytm, Social organiseringsform samt Genre, i relation till tidigare nämnd litteratur. / The purpose of this study is to examine how piano teachers in Sweden work with pulse, meter and rhythm when they teach, and to discover possible correlations between this work and the teacher’s main genre and the form of the lessons (individual or group). The literature that is presented in the background chapter includes suggestions for methods that can be used in the instrumental lessons to work with these aspects. A web survey was used as s a method for the study. The survey questions asked reflect the teaching methods presented in the literature review. The results section shows the analysis of responses to the survey, which was answered by 30 respondents. Generally speaking, the suggested methods are not being much used. A correlation between the form of the lessons and the work with pulse was discovered, which shows that teachers with individual lessons according to this study work more with pulse than teachers whose students receive both individual and group lessons. In the discussion section the following six themes are lifted in relation to previously presented literature: Pulse, Meter, Rhythm, Piano teacher’s work with pulse, meter and rhythm, Social form of the lesson and genre.

Syfte: Ett flertal studier har undersökt om socialt ansvarstagande (CSR) är lönsamt, men inga entydiga bevis finns. Tidigare undersökningar har dock implicit antagit att CSR-aktiviteter är lönsamma oavsett hur de implementeras. Vi ifrågasätter detta antagande och undersöker hur implementeringen av CSR påverkar dess lönsamhet. Vi undersöker om variablerna takt, konsekvens och väg förklarar relationen mellan CSR och bolagens lönsamhet. Metod: Studien är utförd enligt ett positivistiskt perspektiv med en hypotetisk-deduktiv ansats och en longitudinell design med fem års observationer. Data har insamlats från Thomson Reuters Eikon och Thomson Reuters Datastream. Data har analyserats med statistiska metoder. Resultat & slutsats: Studien visaratt implementeringen av CSR påverkar bolags CFP och studien diskuterar de teoretiska förutsättningarna för sådana effekter. Bolag kan påverka lönsamheten av CSRgenom att implementera den på rätt sätt. Förslag till fortsatt forskning: Ett förslag till fortsatta studier av CSR-implementering är att inte bara mätabolagens redovisningsmässiga mått utan även se på de marknadsmässiga. Att mäta bolag CSR-aktiviteter med start i tidigare årtal än vi gjort kan dessutom öka möjligheten att mäta effekter av implementering. Uppsatsens bidrag: Föreliggande studie utvidgar CSR-litteraturen och redovisningslitteraturen genom att (1) diskutera hur implementering av CSR kan påverka dess lönsamhet och (2) empiriskt undersöka effekten av implementering av CSR på lönsamhet. Det praktiska bidraget är att kunskap om hur implementering av CSR kan påverka lönsamheten är till nytta för all implementering av CSR och för behovet av lagstiftning om socialt ansvarstagande. / Aim: A number of studies have investigated whether social responsibility (CSR) is profitable, but no unambiguous evidence exists. However, previous surveys have implicitly assumed that CSR activities are profitable regardless of how they are implemented. We question this assumption and investigate how the implementation of CSR affects its profitability. We investigate whether the variables pace, consistency and path explain the relationship between CSR and the company's profitability. Method: The study is conducted in a positivist perspective with a hypothetical deduction. The procedure is quantitative and secondary data has been collected from Thomson Reuters Eikon and Thomson Reuters Datastream. The data from this longitudinal study has been analyzed and processed in MiniTab. Result & Conclusions: The study is conducted in a positivist perspective with a hypothetical deduction and a longitudinal design with fiveyear’s observations. Data has been collected from Thomson Reuters Eikon and Thomson Reuters Datastream. Data has been analyzed using statistical methods. Suggestion for future research: A proposal for further study of CSR implementation is to not only measure the company's accounting standards but also look at the market-related. Measuring companies CSR activities starting in earlier years than we did can also increase the ability to measure effects of implementation. Contribution of the thesis: Present study extends the CSR literature and accounting literature by (1) discussing how implementation of CSR can affect its profitability and (2) empirically investigates the impact of CSR implementation on profitability. The practical contribution is that knowledge about how the implementation of CSR can affect profitability is beneficial to all implementation of CSR and the need for social responsibility legislation.

The first part of the thesis is dedicated to introducing the company's history, products, and selected economic indicators. The following part is a theoretical analysis of types of assembly lines, their characteristics and methods for determining the consumption standards of time. The practical part analyzes time efficiency of a specific assembly line. The results of the analysis are presented in table and graphs based on three proposals that are designed to reduce the production cycle. The final part provides techno-economic overview and valuation of improvements designed according to the key indicators presented in the thesis.

Currently, there is a monthly breach with its vehicle delivery policy. This policy refers to said company, it refers to a minimum of 92% of units towards the points of sale. However, in the last quarter of 2017 and the semester of 2018, it has only been met from 82% to 90%. These are 5% -10% that have not come to meet in each month, but also directly to the profitability of the company. On the one hand, storage costs are increased by each car that does not arrive or dissatisfaction is generated by the customer, this is the problem of 3 main causes, which is the installation time of radios, installation of alarms and more vehicles that are not served in the damage assessment area. As a root cause, we have the first, since, on the one hand, a bottleneck is generated by the lack of car attention and, on the other hand, represents 20% of the monthly sales of the case study, For what needs to be done to reduce this bottleneck and increase the capacity of the vehicles in this area, the damage is detailed, two lines of evaluation are carried out. This type of triage, we ensure a standardized work, since there was a group of vehicles waiting with different types of damage in the same operating line. Also, the delivery of vehicles on time is improved to 95% and the times of the areas of installation of radios, installation of alarms and damage assessment are reduced by 42.85%, 51.42% and 50% respectively.
