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.

This Master's thesis deals with the optimization of the material flow between two areas of the production plant of the selected company. At the beginning of the thesis there is shown theoretical framework which is needed for subsequent analysis and determination of the proposals to improvement. In this part there is pointed out to the understanding of the process and the various concepts related to the process management. Furthermore, for the purposes of the application part there are selected and analyzed specific tools of lean manufacturing. These include for example the spaghetti diagram, the product / process matrix and the value stream mapping as the essential tool of this thesis. All this is complemented by ABC analysis. After that these methods are also applied in the practical part for solving the current project in the selected company. At first in solving the project there is dealt with the determination of the most problematic material flow between two areas of production plant. Then there is suggested the optimization solutions and all of this is also complemented by the economic evaluation of the whole project.

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.

Globale Krisen, Rohstoffengpässe oder Preisschwankungen stellen die globalisierten Lieferkettensysteme der westlichen Produzenten vor große Herausforderungen. Das Konzept der Kreislaufwirtschaft ist eine Möglichkeit, sich angesichts dieser Herausforderungen robuster zu positionieren, um weniger abhängig von äußeren Einflüssen zu sein. Die größte Hürde bei dem Aufbau von Netzwerken für Kreislaufwirtschaftsprozesse ist die Identifikation von potentiellen Partnern auf Basis von Stoffstrommodellen. Ein erfolgreiches Mapping ist von vielen Faktoren abhängig. Aktuell existiert kein Ansatz, um die Stoffströme so zu modellieren, dass die Darstellung und Berechnung für eine Partnersuche in der Kreislaufwirtschaft geeignet ist. Um der Komplexität, sowohl der Stoffstrommodellierung, als auch der Partnersuche gerecht zu werden, wird hier ein MBSE-Ansatz gewählt - ein überlegener Modellierungsansatz im Detaillierungsgrad und der Adaptionsfähigkeit. Das Modell verknüpft die 3 Hauptelemente der Wertstromanalyse (Produktionsprozess, Materialfluss und Geschäftsprozess) und ermöglicht dadurch neuartige Kennzahlen zu ermitteln. Diese Kennzahlen und die detaillierte Modellierung schaffen eine verbesserte Informationslage, auf Basis derer die Effektivität der Partnersuche in der Kreislaufwirtschaft signifikant gesteigert wird. Nach einer theoretischen Herleitung der Modellierungslogik und der Erweiterung des bestehenden Ansatzes der nachhaltigen Wertstromanalyse (engl. Sustainable Value Stream Mapping – Sus-VSM) wird anhand eines Beispiels das MBSE-Modell implementiert und validiert. Dieser MBSE-Ansatz besitzt das Potential, die Beschreibung industrieller Produktions- und Herstellungsprozesse erheblich zu verfeinern und dadurch Analysen und Berechnungen zu optimieren, was zu einer besseren Vernetzung der Industrie führt. Die dadurch identifizierten industriellen Symbiosen fördern die Kreislaufwirtschaft maßgeblich und helfen Ressourcen nachhaltiger zu nutzen.

This diploma thesis deals with eliminating of bottlenecks in a production of eletrical devices, focusing mainly on the production line. It analyzes the current situation and using value stream mapping for a selected product it identifies bottlenecks of the production process. Further it proposes remedial measures to improve current situation.

The topic of diploma thesis was implemented in selected mechanical engineering company producing precision parts in small series. The main aim of the thesis is to create the suggestion of optimal supply process for new orders. The first part of thesis describes the company, area of its business and the processes of the order. In second part, the production analysis is carried out: production order path, production analysis for two reference parts, comparison of all time delay over two last years, find bottlenecks in the supply process. Base on analysis, theoretical approaches was described. In the last chapter there are suggestions for improvement of supply processes and thus shortening of production time of new orders.

Con el propósito de neutralizar los diversos problemas de pérdidas productivas, en los procesos constructivos se desea implementar la herramienta Value Stream Mapping (VSM) la cual pertenece a la filosofía Lean Manufacturing que es implementada en Lean Construction, con el fin de tener una construcción sin pérdida, dicha herramienta consiste en la creación de mapas que representan el procedimiento de las actividades y flujos de información necesarios para obtener un producto en su etapa final, en este caso sería la obtención de un elemento estructural. La cual nos podrá ayudar a obtener un diagnóstico del estado actual de los procesos. Value Stream Mapping no solo detecta los problemas productivos desde su origen, si no te ayuda a poder proponer mejoras en los procesos con el objetivo de poder eliminar las pérdidas productivas del proyecto en general. Una vez analizada las propuestas de mejora se procederá a realizar un mapa de estado futuro obteniendo un mayor rendimiento en el ciclo de producción. Los datos obtenidos en campo fueron tomados en un periodo aproximado de 3 meses en la obra “Condominio Bolivia Nº 4848” (Edificio Multifamiliar) dichos datos permitieron obtener el rendimiento productivo actual de los procesos, mediante la herramienta Value Stream Mapping se procedió analizar el estado actual y elaborar el mapas de flujos de valores para ver el estado futuro del proceso del elemento estructural. Para la elaboración del mapa del flujo de valor futuro se consideró las mejoras obtenidas por el Value Stream Mapping, finalmente, se justifica que si se puede mejorar los procesos constructivos a través de la herramienta Value Stream Mapping. / In order to neutralize the various problems of productive losses, in the construction processes we want to implement the Value Stream Mapping (VSM) tool which belongs to the Lean Manufacturing philosophy that is implemented in Lean Construction, in order to have a lossless construction, this tool consists in the creation of maps that represent the procedure of the activities and information flows necessary to obtain a product in its final stage, in this case it would be to obtain a structural element. Which can help us get a diagnosis of the current state of the processes. Value Stream Mapping not only detects productive problems from its origin, it does not help you to be able to propose improvements in processes in order to eliminate the productive losses of the project in general. Once the improvement proposals have been analyzed, we will proceed to make a future status map obtaining a higher performance in the production cycle. The data obtained in the field were taken in a period of approximately 3 months in the work "Bolivia Condominium No. 4848" (Multifamily Building) this data allowed to obtain the current productive performance of the processes, using the tool Value Stream Mapping proceeded to analyze the current state and develop the value flow maps to see the future state of the structural element process. For the development of the future value stream map, the improvements obtained by the Value Stream Mapping were considered, finally, it is justified that if construction processes can be improved through the Value Stream Mapping tool. / Tesis
