Made available in DSpace on 2015-05-08T14:53:31Z (GMT). No. of bitstreams: 1 arquivototal.pdf: 2225329 bytes, checksum: aeb2b58ce9683163296978cd44822c1c (MD5) Previous issue date: 2012-08-30 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This dissertation concerns the application of the Activity Based Costing method (ABC) as a tool to hold cost reduction in service companies. The first step was the contextualization of the method importance followed by the justification of the research. After that, a literary review was made and it involved value chain, cost management, ABC method, time-driven ABC, target costing, kaizen costing, value stream mapping and tourism. Based on the researched literature this survey could be separated in three phases: (1) application of the costing method in service costing, (2) application of the value stream mapping in services with a greater incidence of indirect costs and (3) suggestion of a more appropriated cost reduction technique to the service in analysis. This research is exploratory and applied; it is also focused on three case studies in service, two restaurants and a travel agency. The results obtained with the survey indicate service costs and point out the ABC method as an auxiliary tool in the search for cost reduction, having in mind that the more accurate treatment of indirect costs provided by ABC method facilitated the identification of the services which needed wastage analysis. In the last chapter the final considerations related to the research are presented as well as suggestions for future searches. / Esta dissertação trata da aplicação do método de custeio ABC (Activity Based Costs) como ferramenta de suporte à redução de custos em empresas no setor de serviços. Primeiramente, contextualizou-se a importância do método e justificou-se a realização da pesquisa. Em uma etapa posterior realizou-se uma revisão de literatura sobre cadeia de valor, gestão de custos, método de custeio ABC, time-driven ABC, custeio-meta, custeio kaizen, mapeamento do fluxo de valor, finalizando com uma breve revisão no setor de serviços com ênfase na atividade turística. Baseado na literatura pesquisada dividiu-se este estudo de caso em três fases: (1) Aplicação do método de custeio ABC em três empresas do setor serviços, (2) Aplicação do mapeamento do fluxo de valor nos serviços com maiores incidências de custos indiretos e (3) sugestão de técnica de redução de custos mais apropriada para o serviço em análise. A pesquisa possui natureza exploratória e aplicada, focada em um estudo de três casos no setor de serviços, dois restaurantes e uma agência de viagens. Os resultados obtidos na pesquisa indicam os custos dos serviços prestados e aponta o ABC como uma ferramenta auxiliar na busca pela redução de custos, pois o tratamento mais acurado dos custos indiretos fornecido pelo ABC facilitou a identificação dos serviços que necessitavam de uma análise nos desperdícios. No último capítulo são apresentadas as considerações finais acerca da pesquisa e sugestões de pesquisas futuras.

Hälsoekonomisk utvärdering av ett nytt arbetssätt för behandling av knäskador : En studie gjord på ortopedkliniken på Länssjukhuset i Kalmar / Health-economic evaluation of a new work procedure for treatment of knee injuries : A study at the orthopedic clinic at the County Hospital in Kalmar

Leku, Faton, Perikala, Louis January 2017 (has links)
Bakgrund: Kostnadsökningen inom hälso- och sjukvården har varit ett stort problem sedan 1980-talet och kommer att fortsätta vara ett problem i framtiden. Det har lett till en mer ansträngd ekonomisk situation som hälso- och sjukvården fått förhålla sig till. Därför är det av stor vikt att de disponibla medel som finns inom hälso- och sjukvården allokeras till de områden där de skapar som mest nytta. Syfte: Syftet med studien är att göra en hälsoekonomisk utvärdering av ett nytt arbetssätt för behandling av knäskador på ortopedkliniken på Länssjukhuset i Kalmar. Metodval: Studien är utformad som en utvärderingsstudie med en abduktiv utgångspunkt. Datainsamlingen har skett utifrån semistrukturerade intervjuer på LSK med personal som är involverad i projektet. Utöver de semistrukturerade intervjuerna har även numeriska data utgjort en del av studiens empiri. Slutsats: Efter genomförd studie kan vi konstatera att fler hälsoekonomiska utvärderingar behövs på icke-nationella nivåer för att stödja verksamheter inom hälso- och sjukvården. Det är viktigt att det aktivt arbetas med effektiviseringsarbeten inom offentliga verksamheter som främst finansieras av skattemedel. Vi kan även konstatera att det nya arbetssättet är mer lönsamt än det gamla både monetärt och icke-monetärt där förändringen bidragit med flera vinningar som exempelvis kortare ledtider, bättre samarbete och utökad kompetens. / Background: The cost increase in healthcare has been a major problem since the 1980s and will continue to be a problem in the future. This has led to a more strained economic situation for the healthcare sector. Therefore, it is of the utmost importance that the available funds in the healthcare sector are allocated to the areas where they are most beneficial.  Purpose: The purpose of this study is to make a health-economic evaluation of a new work procedure for the treatment of knee injuries at the orthopedic clinic at Kalmar’s County Hospital. Method: The study is designed as an evaluation study with an abductive outset. The data collection has been based on semi-structured interviews at LSK with the staff that was involved in the project. In addition to the semi-structured interviews, numerical data has also been part of the study for the empirical data collection. Conclusion: After completion of the study, we can state that more health-economic evaluations are needed at non-national levels to support healthcare organisations. It is important to actively work with efficiency initiatives in public organisations that are primarily funded by tax assets. We can also state that the new work procedure is more profitable than the old one, both monetary and non-monetary, where the change of work procedure has resulted in several non-monetary gains, such as shorter lead times, better cooperation and increased competence.

Effektivitetsförbättringar i interna serviceprocesser : En fallstudie inom massa- och pappersindustrin

Björklund, Elina, Gimström, Nina January 2017 (has links)
Effective and reliable delivery of services provides long-term performance to an organization. Inorder to create effective and reliable deliveries, activities that do not create value for the customer,namely the wastes, need to be reduced or eliminated. Value Stream mapping is a Leanmanagement tool that aims to clean processes from the wastes. With this as a starting point, studieshave previously been conducted to customize the tool for use on service processes. The studyresulted in Service value stream management, a model implemented in six steps. When the modelis applied in service processes, there is a wide variety of problems that may occur, it is therefore considered not possible to collect all problems in order to provide suggestions for improvements. This study aims to investigate whether the tool can be modified to better suit an internal serviceprocess in the pulp and paper industry. The literature review that has been conducted, revealedthat the existing model does not contain certain, according to the theory, important elementsadapted for Lean service. Beside the waste and tools that the model already consists of, fourrelevant wastes and twelve tools were found during the literature review. Other interestingcomponents that emerged through the literature review, were the views of what an organizationshould learn about and how successes should be measured. In order to fulfill the purpose of ourstudy, the Lean tool Service value stream management, was tested with the additions found duringthe literature review. The test was conducted at an internal service process at a case company tosee if there is evidence to add or remove some of the new wastes, tools or components to themodel. At the case company, data was collected through interviews and observations as well asthrough a survey. The study resulted in the 5K-model which consists five steps to eliminate andreduce wastes. With this model, organizations in the pulp and paper industry should be able tocreate higher efficiency in their internal service processes. To visualize and measure efficiency, amathematical formula was developed that could be considered useful even outside the 5K model.

Value Stream Analysis of Online Deliveries at Ecommerce Department in a Logistic Company

Bangalore Rajanna, Raghunandan, Prasad Nallaye karthikeyan, Harvind January 2020 (has links)
Lean production is one of the proven approaches for identifying and eliminating the activities that do not add value to the customers and delivering and provide the best possible quality service to customers. Implementation of lean is deemed to be feasible in any organization regardless of its size or industry background. For initiating lean in an organization there are many tools, techniques and approaches that are available. Value Stream Mapping (VSM) is one such tool that is touted as cost-effective and easy to be implemented. This thesis proposes to conduct Value Stream Analysis (VSA) at at e-commerce (online) department at the case company to understand their material and information flows by analyzing the current state and develop implementable solutions to improve the overall productivity of the online deliveries. The tasks to perform are: · To map the current state value stream. · To identify wastages and propose solutions to eliminate them. · To provide productivity improvement proposals. A mix of quantitative and qualitative methods were used in this study for data collection and data analysis. This project, which is designed as a longitudinal case study that pri-marily focuses on gathering accurate, real-time data related to the product family, and on drawing a visual representation of the current materials and information flow. VSM has been implemented and the data were analysed. The results obtained from this study concludes that, VSM is an appropriate technique to initiate lean ways of work in larger firms that lacks sufficient knowledge and experience on lean. In addition to it, produc-tivity improvement proposals provided in this study are considered to be key factors in initiating lean transformation in an organization from a technical point of view while, management support and acceptance of change is necessary from an organizational point of view. This thesis will be useful to researchers, professionals and others con-cerned subject to understand the significance of value stream mapping in larger e-com-merce logistic firms.
