This thesis describes the design of a tipping trailer, from a company?s demands andrequests to complete manufacturing documentation. The design is developed for thecompany Abexor AB in Östersund that produces tipping trailers. The product issupposed to be used by Abexors customer to transport cargos of different kinds,such as gravel, stone, dirt, etc.The work commenced with a meeting at the company where demands were set.After that a pre-study was conducted to find out what traffic rules were required forthe trailer to be allowed to be driven on roads. Similar products were examined tosee how the trailer could be designed.

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.

An increasingly globalized market is leading to hard competition among manufacturing companies, which means that they are forced to become more customer focused to survive in the market. A Customer Relationship Management system is a system that will be of assistance to help companies succeed in building long term relationships with their customers. Best of Breed and ERP-based are two types of CRM systems. The study has focused on analyzing and examine the need for CRM systems at manufacturing companies. Our question formulation has been:? What need do businesses want to satisfy with a Best of Breed-based and ERP-based CRM system?? Are there any differences in the use of Best of Breed-based and ERP-based CRM system?In this study, we have chosen to carry out interviews and quantitative surveys with manufacturing companies to get their view of CRM-systems.

This examination work is performed at the institution of industrial economy and production at Jonkoping technical university, for JELD-WEN Door Solutions plant in Forserum.Today the focus in the company is on to reduce their inventories binding of capitals as well as inventory of products and that includes to get a good control of the supply and handling of material which is of great importance.JELD-WEN Door Solutions is one of the worlds leading producers of windows and doors and the head-office is located in Oregon, USA.A great number of wooden doors are manufactured by the company in varying of constructions, classifications and performance.The production of the plant in Forserum has a project- and customer focus manufacturing where only internal doors are produced. The overall market they are concentrated on is to different institution such as schools, hospitals etc.The purpose of this work is to investigate possibilities to improvement of material- and production control at JELD-WEN. The report will handle the master production schedule to and from the production divisions within manufacturing industry. Focus will be on the way for information- and material flows from arrival, transport within the company and further on to customers.Further a map of the flow was performed which gave a clearer picture of the connection between the flow of information- and material for the manufacturing process. On the basis of the mapping of the flow, the group discovered that the flow of material had some improvement potential.

The purpose of this thesis is to outline an appropriate model in order for companies to successfully act and compete physically as wholesalers at the same time as acting on the virtual market by selling directly to the end consumer. The approach of this thesis is hermeneutical and abductive with elements of hypothetically deductive approach. Our research has a qualitative research strategy based on case studies and interviews as well as on secondary data. Interviews were conducted with the case company JaymJay Wear AB as well as with other companies, so called mini cases. The secondary data consists mainly of textbooks, web sites and journals.

Denna studie har undersökt hur en grupp elever använder ett virtuellt rum som klassrum. Effekten blev att de lärde sig fakta med hela kroppen. Det virtuella klassrummet kan bli ett nytt pedagogiskt redskap för skolungdomar där de kan vara med och bygga upp eller påverka innehållet. Studien är en etnografisk undersökning där jag har studerat multimodalitetsteorier av bl.a. Gunther Kress i vilken man tar hänsyn till alla teckenvärldar som ljud, bild, gester och kroppens rörelse i rummet.

Arbetet syftar till att undersöka förutsättningarna för att skapa en virtualiserad utvecklingsmiljö för Windows som installeras och konfigureras utan manuell övervakning. Utvecklare på Sandvik Systems Development (SSD) arbetar ofta med olika utvecklingsverktyg eller använder sig av olika versioner av utvecklingsmiljöer och detta är ett problem. Det är också vanligt att utvecklarna blandar sina kontorsapplikationer med utvecklingsmiljön vilket kan vara en stor säkerhetsrisk. Ett annat stort problem är att tiden kan vara väldigt lång för inhyrda konsulter och nyanställda att få sina utvecklingsmiljöer installerade, vilket resulterar i stora kostnader för SSD. En möjlig lösning till problemen är att använda virtuella maskiner som utvecklingsmiljöer.

This Master Thesis is a product development project that has been carried out in cooperation withSvea Teknik AB. The company has developed an apparatus for attachment of a keel to a hull base ofa boat. The purpose for this thesis has been to compare a new concept of keel attachment incomposite material to thetraditionaldesign solution. This new keel attachment minimizes thedamages that may arise on the keel and the hull of the boat in shape of stresses impacts at grounding.Today it is a problem, relating to keel attachment on sailing boats having a fin keel or a bulbous keel.The manufacture focus on developing larger draught and shorter keel blades. The overall purpose isto increase performance of the sailing boat.The task for this thesis was to develop a concept of keel blade in composite material and investigateattachment to a sheet-shaped element.

Målet med examensarbetet var att skapa ett verktyg för insamling av erfarenhetsdata för produktutvecklingsprocessen. Den skall vara användbar för att bidra till ett systematiskt arbetssätt för produktionsanpassad konstruktion på Volvo Aero Corporation. Det skapade verktyget för insamlande av erfarenhetsdata skall bidra till att produktivitet och producerbarhet kan förbättras på kommande koncept och konstruktioner. En förstudie har genomförts på företaget under hösten 2010 vilket ligger till grund för det beskrivna problemet i examensarbetet.Arbetet avgränsades till att utveckla en struktur för hur metod och erfarenhet skall struktureras och en testversion av verktyget togs fram för utvärdering. Efter samråd med den handledande Verksamhetsutvecklingsgruppen, VU-gruppen, från avdelning 9931 Projekt-, Koncept- och Tillverkningsledning, beslutades att examensarbetet skulle avgränsas ytterligare till insamling av diametermått på komponenten Diffuser Case på Volvo Aero.

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.

In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

This diploma work addresses the question of how much energy is spent whenmanufacturing the components of a building as well as of how much energy is used inthe production of a building. The object of the studies is BioCentrum at the SwedishUniversity of Agricultural Sciences in Ultuna just outside the city of Uppsala. The aimof the work was to investigate how much energy was consumed when manufacturingand production in relation to the management, how many years the production wasrepresented. It was also a study in how mature the construction industry is to answerhow much energy was consumed in manufacturing.In order to get these answers a question form was developed and sent to thesuppliers to BioCentrum. In this form they were to respond to the quantity suppliedto BioCentrum and the amount of energy was spent when manufacturing thecomponents.
