Produkthantering vid tillverkning av roterande verktyg
AB Sandvik Cormorant?s production unit in Gimo has identified a need to examinethe handling of products between operations with the purpose of generatingproposals of improvement for the product handling.The aim of this project is to study the existing manufacturing process and givesuggestions for improvement. The proposals should reduce the manual handling ofproducts, decrease the risk of damaging the products during the manufacturing andform a basis for increased traceability. Based on a mapping of the manufacturingprocess and the problem description, a specification of requirements has beencomposed.The mapping of the manufacturing process suggests that a change of the currentsystem is required. The company is recommended to decide how the producthandling between operations should be performed as guidelines for the productionteam.
Förstärkning av bro 17-803-1 : En jämförelse av förstärkningsmetoder
AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.
Likvärdig bedömning? : Så tolkar idrottslärarna värdeorden "till viss del", "relativt väl" och "väl" utifrån kunskapskraven i Lgr 11
The core process is responsible for internal business development and is the process that runs through the organization and the results which creates a value for the customer. Some research suggests that identification of the client's conscious or unconscious needs clarifying the so-called core process in the organization and operations can thus be more effective. The study aims to identify and analyze the experience of the core process within child health care. The method has been interviews with nine managers and 10 clinic nurses in a county. The results show a lack of knowledge regarding core process and process work.
Svensk plantskoleproduktion 2003 :
This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm.
Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).
Uppbygnad av ett logiskt flöde vid produktionsövertag
The situation at Plastal AB is following; the plant in Simrishamn has not capacity enough but the plant in Kristinehamn has unused capacity. My task with this master thesis is to build a logistic flow between this two plants, optimize purchase quantities and ensure delivery safety.The production of the Intermediate Section (LS) will be divided between the plants. The LS will be produced in the following way; the injection moulding process will be done in Simrishamn and the assembling and lacquering processes in Kristinehamn, The reason to divide the production is to ensure delivery safety. Plastal AB can not move the whole production of the l.S because the two plants have different processes (moulding res. injection moulding).When the 1.5 has been transported to Kristinehamn following moments are included in this order; lacquering, welding and assembling.

Flexibla fixturer i bearbetande maskiner
This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS.
Biogasrötning av socker- och foderbetor : Jämförelse av färska, stuklagrade samt ensilerade betor i laboratorieskala
Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.

En studie om Lean Production som effektivitetsteori i virkesanskaffningsprocessen : ett hjälpmedel för ökad effektivitet med kunden i fokus
Effektivitet är för många organisationer ett begrepp som förknippas med att utnyttja sina resurser maximalt. Detta är något som även är märkbart inom svenskt skogsbruk, där man idag är mycket mån om att vara resurseffektiv i sin verksamhet. Det finns dock fler innebörder av effektivitet som begrepp. Toyota, med sitt Toyota Production System, och lean production har bevisat att en flödeseffektiv process med kundfokusering kan vara ett framgångsrikt arbetssätt.
Denna studie tar upp lean production som teori i svenskt skogsbruk och knyter an denna mot virkesanskaffningsprocessen.
Varelsedesign : en metod
My aim in this case study has been to create a method for creature design to test this method in a production and evaluate the results. To achieve this I studied and analyzed the methods of three concept artists and illustrators named James Gurney, Neville Page and Iain McCaig. From the analysis of these artist´s methods, combined with my own personal experience, a new method was formed. To test this method a creature was designed based on directives given by a game design group in the process of creating a table top role playing game in a fictitious world. These directives where given for the creature´s role and its living conditions.
Lean inom den svenska bankbranschen : En studie av svenska storbankers arbete med Lean
Lean Production har sedan länge enbart varit förknippad med tillverkningsindustrin och främst Toyota genom Toyota Production System(TPS). På senare år har Lean Production i allt högre grad introducerats och integrerats i tjänsteföretag under beteckningen Lean Service. Bankbranschen är en bransch där aktörer globalt anammat de bakomliggande filosofierna av Lean Production och Lean Service. I det här arbetet har en undersökning gjorts kring huruvida Lean Production existerar inom svenska banker och om så är fallet hur filosofierna inom Lean Production präglar bankerna. De tre bankerna som valts för undersökningen är de svenska storbanker Nordea, SEB och Handelsbanken.
Terminalisering hos JM AB
During the last decade, the construction industry has focused on improving and optimising its Production process. The construction industry is now facing larger changes regarding efficiency in their supply chain for the next decade. Many companies are now trying to optimise its supply chain together with its supplier. JM AB, which is one of the biggest construction companies in Sweden, is looking at different options to improve its own logistics together with their suppliers. One option is to use a terminal between JM and the suppliers to solve problems such as quality, custom service and inventory for the in production.
Automatisering av spraytorkningsprocess
ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.
