Flödeslogistik vid Laponia Hotel / Flow Logistics

Eriksson, Ingela January 2002 (has links)
<p>The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout. </p><p>In order to find the best system I have chosen to analyse three different logistic models, each representing different levels of logistic systems. The first model, representing the logistics of a small restaurant, is named ´the simple logistic model´ and has a manual system. The second method is called ´the complex logistic model´. This model describes the hotel that is too small to afford a full-scale computer system, and too complex to operate with only a manual system. The last model is'the advanced logistic model'and it is meant to represent the full-scale logistics with all necessary computer aid. </p><p>The models are analysed by the SWOT method and the materials used are found through literature research, interviews and observations. The analyse shows that the best model for Laponia Hotel's restaurant would be the advanced logistic model in combination with the simple logistic model. This would allow the restaurant to use all the benefits of computer aid and large quantities without loosing the small-scale feeling of ownership and responsibility among the employees.</p>

Skillingaryds stålrörsindustri AB handles different kinds of steel pipes and got their market mainly in the furniture industry and in department stores. At the moment the company find themselves in a strong up going course. In a few years the company’s turnover has increased with over 10 million SEK. This has led to a demand for structure changes and reorganizing through the company. The development has forced the company to invest in new premises, which must be adapted for the production and further expansion of the company. This report describes how an analysis of the present layout has been made and how effectivity and flow can be improved between machines, storage and personal. By using the method Simplified systematic layout planning, three proposals have been made. To give the clearest picture as possible of the layouts, all machines and buildings were drawn in a 3D CAD-program called Solid Works. This will also give the company resources to continue to work with the material in case of another expansion. Suggestion D scored the most points in the valuation and is considered to be the best solution. It is based on a big central storage and a compact machine park. The suggestion provides a smooth flow through the production line and short distances between machines while having large spaces for storage and assembly. During the course of this paper a few instances of superfluous transports, bad storage handling and lack of order have been detected. Skillingaryds stålrörsindustri AB is recommended to start working with 5S. Labelling of articles is of importance when it comes to create order and standardization of areas to help the personal to find the items they need.

Jämförelsestudie mellan två layoutmetoder samt förslag till ny verksamhetslayout / Comparative study between two layout methods as well as proposal for a new business layout

Ulfheden, Linnea January 2019 (has links)
Avdelningen Aviation på Eltel Networks Infranet AB arbetar ständigt för att erbjuda kostnadseffektiva tjänster för flygtrafiken för att säkerställa hög luftsäkerhet. Eltel Networks verksamhet är helt kundorderstyrt. Verksamhetslayouten är statisk och anpassas inte utefter kundernas behov. Eltel Networks vill få större kontroll på materialflödet och skapa en mer flexibel verksamhet. Inför ett layoutplaneringsprojekt kan metoden systematisk lokalplanläggning användas på ett systematiskt tillvägagångssätt. Metoden används av organisationer för att designa eller omdesigna en anläggning. Det finns även en förenklad version av systematisk lokalplanläggning. Syftet med studien var att jämföra två layoutmetoder samt ge förslag på ny verksamhetslayout utifrån jämförelsen. En jämförelsestudie genomfördes av de två layoutmetoderna med utgångspunkt vilken metod som passar bäst för mindre materialflöde och minde lokalyta. Förslag på en ny layout ska ges med hänsyn till att hitta en mer flexibel verksamhet. Utifrån jämförelsen framkom det att metoden förenklad systematisk lokalplanläggning är bäst lämpad att genomföras för en layout med mindre materialflöde och mindre lokalyta. Förslag till en mer flexibel verksamhetslayout har presenteras utifrån metoden förenklad systematisk lokalplanläggning. / The department Aviation at Eltel Networks Infranet AB is constantly working to offer cost effective air traffic services to ensure high air safety. Eltel Networks business is completely customized. The business layout is static and does not match customer needs. Eltel Networks want to gain more control over the material flow and create a more flexible business. Facing a layout planning project, the method systematic layout planning can be used in a systematic approach. The method is used by organizations to design or redesign a facility. There is also a simplified version of systematic layout planning. The purpose of the study was to compare two layout methods as well as propose a new business layout based on the comparison. A comparison study was carried out by the two layout methods based on which method best suits less material flow and less space. Proposals for a new layout should be given with regard to finding a more flexible business. Based on the comparison, it was found that the simplified systematic layout planning method is best suited for a layout with less material flow and less space. Proposals for a more flexible business layout have been presented based on the simplified systematic layout planning method.

Flödeseffektivisering och systematisk effektivisering av fabrikslayout vid lokalbyte för Permanova Lasersystem AB / Flow efficiency and systematic streamlining of the factory layout at the facility move for Permanova Laser Systems AB

Palmblad, Oscar January 2021 (has links)
Marknaden för industriella lasersystem förväntas att växa i framtiden, vilket leder till att producenter utav dessa system måste förbereda sig för att möta marknadens krav. Ett av dessa företag är Permanova Lasersystem AB som arbetar med att ta fram lasersystem, legotillverkning och optik för kunder. Målet med detta projekt är att öka produktionen av standardoptik från stycktillverkning till 50 optik/år och att hjälpa Permanova ta fram en layout till deras nya anläggning som de ska flytta till. Målen för projektet kan delas in i tre huvudmål: • Ta fram ett optimalt produktionsflöde • Ta fram en optimal fabrikslayout • Ta fram optimala arbetsstationer För att uppnå dessa mål har metoder inom LEAN applicerats, såsom värdeflödesanalyser, 7+1 slöseri, kanban, Just in time och flaskhalsanalyser. För att ta fram optimala layouter för företaget har även förenklad systematisk lokalplanläggning applicerats. För att skapa ett optimalt produktionsflöde skapades först en värdeflödesanalys för nuvärdet, vilket visade på hur produktionen sker idag samt vilka förbättringsmöjligheter som finns. Till denna nuvärdesanalys gjordes en tidsstudie på nuvarande standardoptik som låg i grunden för senare balansering i produktionen. En värdeflödesanalys för framtida produktion utvecklades från nuvärdesanalysen och dess förbättringsmöjligheter, vilket gav ett nytt produktionsflöde med en mer optimal affärsmodell för framtiden. Förenklad systematisk lokalplanläggning applicerades i 3 iterationer, en för varje utrymme som projektet arbetade med. Dessa tre iterationer var för huvudlayouten, verkstaden och renrummet. För huvudlayouten fanns det 3 huvudkoncept där verkstadens placering styrde vart de andra av Permanovas affärsområden placerades. Det vinnande av dessa huvudkoncept vidareutvecklades och skapade en layout som uppfyllde alla företagets krav samt de flesta av deras önskemål. Flera verkstadslayouter togs fram för varje huvudlayout, där det vinnande konceptet utvecklades vidare till ett koncept som applicerar värdeflödesanalysen för framtiden väl. Denna layout minimerar transportsträckor mellan arbetsstationerna och ökar produktiviteten. För renrummet utvecklades flera koncept men för endast ett utrymme då alla renrumsytor liknande varandra. Det vinnande konceptet vidareutvecklades och skapade en layout som är lik dagens produktion i renrummet, vilket var något som montören ansåg fördelaktigt. / The market for industrial laser systems is expected to grow in the future, which means that manufacturers of these systems must prepare to meet market demands. One of these companies is Permanova Lasersystem AB, which works with developing laser systems, contract manufacturing and optics for customers. The goal of this project is to increase the production of standard optics from single-piece production to 50 optics/year and to help Permanova develop a layout for their new facility, which they will move to. The goals of the project can be divided into three main goals: • Develop an optimal production flow • Develop an optimal factory layout • Develop optimal workstations To achieve these goals, methods within LEAN have been applied, such as value steam mapping, 7 + 1 wastes, kanban, Just in time and bottleneck analysis. To produce optimal layouts for the company, simplified systematic layout planning has also been applied. In order to create an optimal production flow a value stream map for the present production was created, which showed how the production works today and what opportunities for improvement exist. For this value stream map a time study was made on the current standard optic, which was the basis for later balancing in the production. A value stream map for the future state of production was also developed from the first value stream map and its opportunities for improvement, which provided a new production flow with a more optimal business model for the future. Simplified systematic layout planning was applied in 3 iterations, one for each area the project worked on. These three iterations were for the main layout, the workshop and the clean room. For the main layout there were 3 main concepts where the workshop's location controlled where the other of Permanova's business areas were located. The winning of these main concepts was further developed and created a layout that met all the company's requirements as well as most of their wishes. Several workshop layouts were developed for each main layout, where the winning concept was further developed into a concept that applies the value steam map for the future well. This layout minimizes transport distances between workstations and helps increase productivity. For the clean room, concepts were developed for only one of the possible spaces because all clean room spaces were similar to each other. The winning concept was further developed and created a layout that is like today's production in the clean room, which was something that the operator considered advantageous.
