This analysis was accomplished in the Nevoga corporation Znojmo.

Purpose – The practical purpose of the study is to find an efficient logistics solution that takes in to consideration the cost, delivery performance and delivery quality for a furniture manufacturer. To fulfil the purpose three objectives have been formulated: To map a furniture manufacturer’s logistics flows and identify any potential wastes. To present an efficient logistics solution for a furniture manufacturer operating in the Nordic countries. To investigate the effect of outsourcing on delivery performance and delivery quality for a furniture manufacturer. The academic purpose of the study is to investigate if existing theories in Lean and value stream mapping can be applied to logistics flows to map and improve efficiency. This is fulfilled by achieving the first two objectives stated above. Method – In order to achieve the purposes literature studies have been conducted in order to give a theoretical background on the subject. A case study was conducted in order to test the theories against empirical data gathered at a furniture manufacturer. The empirical data was gathered by interviews and document studies. Findings – The furniture manufacturer’s logistics flows were mapped and evaluated using an improvement model from the Lean theory. The mapping identified a number of wastes and areas of improvement. A future state with a more efficient flow could then be stated. In order to implement the future state some logistics activities may need to be outsourced to a third party. By using evaluation tools a supplier may be selected without negative impact on delivery performance or delivery quality. Implications – The study has shown that methods for value stream mapping can be used in more areas than practiced today. By using Lean tools companies can identify wastes within their logistics processes and thereby achieve a more efficient management. Limitations – The scope of the study is relatively limited and for a more generalisable result additional flows at the studied company as well as other companies would have to be studied. When mapping logistics flows at international corporate groups a common strategy for streamlining flows is important already at the beginning of the improvement. The study was conducted at a distribution centre in Sweden and no consideration was taken to other parts of the group. Transports has traditionally been regarded as a non-value adding activity but in order to conduct the study transports had to be defined as value adding since distribution of products is necessary. / Syfte – Studiens praktiska syfte är att finna en effektiv logistiklösning som tar hänsyn till kostnader, leveransprecision och leveranskvalitet för ett företag inom möbelbranschen. För att uppnå syftet har tre delmål formulerats: Att kartlägga ett möbelföretags logistikflöden och identifiera eventuella slöserier. Att ta fram en effektiv logistiklösning för ett möbelföretag med tillverkning i nordiska länder. Att utreda påverkan på leveransprecision och leveranskvalitet vid outsourcing av logistikverksamhet hos ett möbelföretag. Studiens akademiska syfte är att undersöka om befintliga teorier inom Lean och värdeflödesanalys kan tillämpas för att kartlägga och förbättra effektiviteten i logistikflöden. Detta uppfylls genom att uppnå de första två delmålen formulerade ovan. Metod – För att uppnå syftena har litteraturstudier använts för att lägga en teoretiskt grund inom ämnet. Vidare genomfördes en fallstudie för att testa teorierna mot empiri insamlad hos ett fallföretag inom möbelbranschen. Empirin bestod av intervjuer och dokumentstudier. Resultat – Fallföretagets logistikflöden kartlades och utvärderades med hjälp av en förbättringsmodell från teorin. Kartläggningen visade på ett antal slöserier och förbättringsområden i flödet. Ett önskat framtida läge med ett effektivare flöde kunde därefter ritas upp. För att kunna genomföra det önskade framtida läget kan vissa logistikaktiviteter behöva outsourcas till en tredje part. Genom att använda verktyg för utvärdering kan leverantör väljas utan negativ påverkan på leveransprecision och leveranskvalitet. Implikationer – Studien har visat att metoder för värdeflödesanalys kan användas inom fler områden än vad som görs idag. Med hjälp av de verktyg som finns inom Lean kan företag synliggöra slöserier inom sina logistikprocesser och därmed få en mer effektiv hantering. Begränsningar – Studiens omfattning är relativt begränsad och för ett ännu mer generaliserbart resultat skulle fler flöden hos fallföretaget samt hos andra företag behöva studeras. Vid kartläggning av logistikflöden hos internationella koncerner är en gemensam strategi för att effektivisera flödena viktig redan vid starten av förbättringsarbetet. Studien är genomförd vid en logistikcentral i Sverige och hänsyn har inte tagits till övriga delar i koncernen. Transporter har i klassisk värdeflödesanalys betraktats som en icke värdeskapande aktivitet men för att kunna genomföra studien har de behövt lyftas till att vara en värdeskapande aktivitet som är nödvändig för att distribuera företags produkter.

Throughout history companies have come to realize the importance of work revolving quality in order to remain competitive on the market. Process development is a natural part of quality management. There exists several different philosophies and tools to make use of in this work, examples are Lean Production and Six Sigma. The state of research of the programs are well studied, but the combination of Lean and Six Sigma's work methodology DMAIC has many unknowns. The objective with this study has been to integrate Lean with DMAIC. The study's purpose has been to investigate whether DMAIC is consistent with theories about Lean. The question this study tried to answer is how Lean-DMAIC can be used to minimize inconsistencies in flow of information in a global production company. The purpose of this paper has mainly been answered with the aid of the literature study. The question at issue has mainly been answered by the case study. The objective has been answered with a combination of the case- and literature study. The work procedure is based on DMAIC´s methodology, while Lean provided the tools for success in combination with the philosophy´s train of thought that permeate the work. The results of the study illuminated that Lean-DMAIC works in a simultaneous fashion in order to find inconsistencies in existing flows of information; with these results the study's question has been answered. By the end of the study it was possible to ascertain that a better question for this particular study would have been how Six Sigma is consistent with Lean, as DMAIC is a method, thus they cannot be directly compared. In this study, DMAIC provided the step-for-step method for how to model the work and in what manner the process was examined. Lean on the other hand provided the right tools and the train of thought in order to succeed. This culminated in that several improvement measures could be produced based on the study's results. / Företag har under historiens gång kommit att förstå vikten av kvalitetsarbete för att vara konkurrenskraftiga på marknaden. Processutveckling är en naturlig del av kvalitetsarbete och det finns olika filosofier och verktyg tillgängliga för ändamålet, exempelvis Lean Production (Lean) och Sex Sigma. Forskningsläget av dessa program är välstuderade, men kunskapen om kombinationen av Lean och Sex Sigmas arbetsmetodologi Define-Measure-Analyze-Improve-Control (DMAIC) är lägre. Målet med undersökning är därför att integrera Lean med DMAIC och syftet är att utreda huruvida DMAIC är konsistent med teorier om Lean. Studiens frågeställning har varit hur Lean-DMAIC kan användas för att minimera avvikelser i informationsflöden i ett globalt produktionsföretag. Syftet uppnås med hjälp av en litteraturstudie, frågeställningen besvaras med hjälp av en fallstudie och målet med en kombination av studierna. Fallstudiens arbetssätt baseras på DMAIC som metodologi för arbetets struktur, medan Leans filosofi genomsyrar arbetet samtidigt som dess verktyg utnyttjas. Resultatet visade att Lean-DMAIC fungerar simultant, både teoretiskt och praktiskt, för att upptäcka avvikelser i informationsflöden. Därmed har undersökningens mål uppfyllts. Efter studien gick det att konstatera huruvida en bättre frågeställning hade varit hur Sex Sigma är konsistent med Lean, eftersom DMAIC är en metod framför filosofi. DMAIC gav steg-för-steg metoden för hur arbeten utformades och processen undersöktes, medan Lean gav verktyg och rätt tankesätt för att lyckas. Detta resulterade i förbättringsåtgärder åt företaget där fallstudien genomfördes.

Globalisering och ökad teknikutveckling samt ökade kundkrav sätter nya krav på la-gerfunktionen. Som ett resultat av detta finns ett behov för företag att arbeta med att förbättra sitt nuvarande lagerarbete. Syftet med denna studie är att undersöka ar-betet på ett råvaru- och färdigvarulager och skapa en modell för ett effektivt lagerarbete inom textilindustrin. Utifrån dessa aspekter syftar arbetet till att skapa en modell för ett effektivt lagerarbete på ett företag inom textilindustrin i Jämtland som har lagerfunktion placerad separat från resten av verksamheten. Med hjälp av observationer och intervjuer samt med genomgång av litteratur har verktyg som Plan-Do-Check-Act (PDCA), Value Stream Mapping (VSM) och aspekter gällande lagerplacering lyfts fram vid skapandet av en modell. Modellen har även tagit hänsyn faktorer för en effektiv lagerverksamhet samt hinder för implementering av förändringar. Faktorer såsom ledningens engagemang, motivation samt hinder i form av en brist av en känsla av sammanhang lyfts fram. En modell presenteras som kan använ-das av företaget samt andra företag i liknande situation. / Globalization, an increasing amount of technology development and higher customer needs put new demands on companies warehousing function. As a result, there is a need for companies to work to further improve their current warehouse processes. The purpose of this paper is to create a model for efficient warehouse operations at a company operating within the textile industry in Jämtland that has stor-age function placed separately from the rest of the business. With the help of observations and interviews as well as a literature review, tools such as Plan-Do-Check Act (PDCA), Value Stream Mapping (VSM), and inventory placement aspects have been highlighted in the creation of a model. The model has also taken into account factors for efficient warehouse operations as well as barriers to implementation of changes. Factors such as management's commitment and motivation as well as obstacles in the form of a lack of a sense of coherence are highlighted. A model is presented that can be used by the company and other companies in similar situations.

In today's market, many companies find themselves in a situation where customers place higher demands on companies. This is a challenge for companies to meet these demands effectively, one way to do it is to implement Lean which can lead to increased productivity, lower costs and better quality. One of the most effective and important tools for streamlining production within Lean is value stream mapping, which identifies the most important activities where they are categorized as value-creating, non-value-creating and waste. There is a clear trend for companies to implement new ways of working that focus on reducing non-value-creating activities. However this can lead to an increased workload, where repetitive tasks are performed at a higher rate without break or variations. However, there is still lack of a knowledge addressed in research and studies on manufacturing organizations, which have contributed to the development of various models for conducting value stream mapping that take ergonomic factors into account.  The purpose of this study is to investigate how an ergonomic value stream mapping can contribute to creating a future production flow with reduced waste and a reduced ergonomic strain in the manufacturing industry. Furthermore, the aim is to investigate how the ergonomic value stream mapping can be used as a basis for a machine investment. The study's primary information has been collected through interviews and observations. Semi-structured interviews were conducted with three respondents as well as structured and unstructured observations.  The results and conclusions of the study show that the proposed changes in the production flow will be able to contribute to a more efficient future production flow with reduced ergonomic load. The ergonomic strain is reduced both at the activity level and for the entire production process. The study confirms that ergonomic value stream mapping can be used as a basis for a machine investment by identifying how changes affect the ergonomic strain and production efficiency.

In today's world the challenge of logistics becomes more and more important for all companies, which consequently contributes to the need of an integrated system of in-house logistics. Goods must flow easily between stations and departments in order to achieve the best utilization of transportation as well as maintaining a good distribution structure to handle these processes in an efficient and effective way to enhance business performance and competitiveness. This report aims to provide research on how to strategically organize, plan and structure the flow of internal logistics within an organization. The research in this study originates from 3 main methods, a theoretical review, a case study and a benchmark. The main idea of the thesis was to contribute with scientific knowledge of improvements that can be achieved within internal logistics targeting companies operating within the service sector. In order to understand the scope of the problem the current state at the case Tropical Islands was analysed and served to identify areas where possible improvements could be achieved. Further on, in combination with the theory and empirical findings the main conclusions of the thesis was the need to strategically organize the flow of internal logistics to improve efficiency and enhance competitiveness. It was made evident that planning is essential in order to successfully implement the milk runs. Other tools could be utilized to further eliminate drawbacks that might occur.

Kurs: Ämnesfördjupande kurs i logistik, 2FE02E, VT 2015 Författare: Martin Norén Kristoffer Nählstedt och Oscar Weberg Handledare: Petra Andersson Examinator: Åsa Gustafsson Titel: En fallstudie om e-handel – Identifierade slöserier i returflödet Bakgrund: I en bransch med mycket returer krävs en effektiv hantering av returer för att inte kostnaderna ska skena iväg. Hela returflödet behöver vara smidigt för att snabbt få ut returnerade varor på marknaden igen. Hur ser ett returflöde ut i nuläget på ett företag i e-handelsbranschen? Returflödet kommer undersökas genom en fallstudie på ett företag. Genom att identifiera slöserier enligt Lean Production förväntas denna uppsats eliminera eller åtminstone reducera identifierade slöserier. Syfte: Syftet med uppsatsen är att identifiera slöserier i returflödet och presentera förbättringsförslag som reducerar nämnda slöserier. Metod: Studien har utförts som en kvalitativ fallstudie med ett deduktivt angreppssätt och ett postpositivistisk synsätt.  Primärdatan har samlats in genom semi-strukturerade intervjuer och observationer. Slutsats: Efter en genomförd Value Stream Mapping analyserar författarna returflödes nuvarande tillstånd. Därefter identifieras slöserier och orsakerna till varför slöserierna uppstår. I slutsatsen presenteras förslag på förbättringar såsom att öka andelen webbreturer och minska avstånden inom lagret.
