Optimering av interna trucktransporter vid Emhart Glass i Sundsvall

Resurssnål produktion är en teori om hur produktionsplanering i ett företag kan förbättras, vilket syftar till att öka effektiviteten och skapa en bättre arbetssituation för medarbetarna i företaget. Examensarbetets övergripande syfte har varit att med stöd i denna teori ta fram ett optimerat och verklighetstroget truckkörschema för dagens interna transporter vid Emhart Glass i Sundsvall. Målsättningen har varit att jämföra de interna transporterna med de behov som finns i företaget, att identifiera hur ofta transporter av tomma lastpallar sker samt att klar-göra om en dubbelpallshantering innebär tidsmässigt vinst. En kart-läggning av de interna transporterna och arbetsställenas behov av lastpallar har genomförts. Informationen från kartläggningen har implementerats i programmet Matlab, där en algoritm för beräkning av ett körschema har skapats som tar hänsyn till dagens tidshantering av lastpallar och sannolikheten att truckförarna lastar av och på lastpallar vid olika arbetsställen.

Motiv och värdering vid köp av skogs- och lantbruksfastigheter i Västerbotten

The study has been done on behalf of and in cooperation with LRF Konsult. The purpose of the study was to try to find out how forest estate buyers valuated different parts of the estate at the time of the purchase and to see if it was possible to identify different trends between different kinds of purchasers. The study is delimited to Västerbotten County and all the purchases were made thru LRF Konsult. The background of the study is that the forest estate purchasers are paying more and more for the forest estates. The prices are often much higher than the net present value which means that they are paying for something more than just the timber value. The study is made with a questionnaire mailed to one hundred forest estate purchasers. Answers got returned from 48 of them.

Nyttjande av det digitaliserade stickvägsnätet vid skogsgödsling med traktor

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

Rapid Exchange Solution (RES) : En mekanisk omlastningslösning för horisontell överföring av containrar mellan olika transportmedel

Detta examensarbete genomfördes våren 2013 på Karlstads universitet där TD Rail & Industry i Västerås stod som uppdragsgivare. Projektet innefattade att kartlägga nuvarande omlastningslösningar av enhetslaster mellan järnvägstransporter och vägtransporter, och utarbeta en konceptuell omlastningslösning med fokus på att öka järnvägstransporternas flexibilitet gentemot vägtransporterna. Där vikten lades på att utarbeta ett välarbetat helhetskoncept.Projektet genomfördes med designprocessen som grund och innehöll bland annat momenten; förstudie, kravspecificering, idégenerering, konceptval m.m.Resultatet blev en vidareutveckling av det redan befintliga systemet CCT som bygger på horisontell överföringsteknik och möjliggör därför omlastning av enhetslaster direkt under kontaktledning. Skillnaden mellan RES och CCT är att man tagit bort ombyggnationen av tågvagn och lastbilschassi, som var en av CCTs stora svagheter, genom två hydrauliska ?teknikplattor?.

Lönsamhet i att avverka virkesrik fastighet innan försäljning

The purpose of this study is to find out the viability in performing final felling in stands with high timber volume or if it´s more profitable to leave these stands to the next owner. Will he or she pay more for the standing stock then the industry? The prices of forest-land have increased significantly over the last couple of years in Sweden and some properties seem to go higher than others. Is this because of higher standing stock volume or can a certain volume/hectare bring a higher price? Maybe a combination of both? This study is based on the the sale-statistics for 2012 from real-estate agency Areal.

Prognostisering av sortimentsutfall från stående skog med hjälp av befintliga data : anpassat till Sveaskog Norrbottens planeringsprocess

This study in the subject of forest planning is made for Sveaskog and its aim is to develop tools that prognosticate outcome in terms of volumes per sort from not yet cut forest stands. The degree of detail is just to get reliable results for at least one months volumes, for Sveaskogs own forestland in the market region of Norrbotten that is about 100 000 m3fub. The course of action to accomplish this is regression analysis and the data consists of cut tracts on own forestland in Norrbotten during the years 2006, 2007 and 2008. That is a little more than 4 million m3fub. Two tools were made.

Teoretisk och experimentell utvärdering av Lättelement AB:s takinfästning

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

Utveckling av golvlucka för hoppgropssystem i kommunal idrottshall

In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.

JÄMTGÅRDEN Dokumentation med fokus på interiörens limfärgsdekor

This bachelor thesis summarises the history of ?Jämtgården? based on literature research andempirical documentation. Jämtgården is a typical 1800th century duplex timber buildingoriginating from the province of Jämtland. However, it was moved to Västernorrlandslänsmuseum in Härnösand in the year of 1918. During the 1920's the museum decided tofocus on the region of Västernorrland and therefore Jämtgården was somewhat left behind.The building's interior walls are decorated with distemper paintings but the current conditionis poor.The aim of this thesis is primarily to compile knowledge about the building and its interiordecorations as well as finding out whether primary distemper paintings, from the periodbefore the relocation, remain on the walls.

Kartläggning av spånprodukter vid Sävar såg

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

Datorspel = Lärande? : En kvalitativ studie angående gymnasieelevers attityder gällande datorspel som läromedel

The gaming market has become the fastest growing market for leisure and is one of the most popular forms of homeentertainment. This has generated a media debate about how people are affected by gaming and concernes how we are affected by the violence that may occur in games. Games proponents argues that gaming is the future of teaching and computer games are becoming a sustainable and popular instruction strategy. Some studies have long used computer games for educational purposes. By interviewing high school students in focus groups as qualitative research, I studied their attitudes towards computer games as a learning tool.

Tillvaratagande av GROT i skärgårdsnära miljö :

The main aim of this study was to investigate and compare different methods for the extraction of forest fuel from environments close to an archipelago. The study was based on relevant literature and published reports as well as personal communications. Forestry has traditionally been characterized by intense efforts to rationalize and mechanize the cutting technique used for timber and pulpwood. In line with the increasing importance of forestry, more concentrated efforts can be expected in the area of techniques and methods, especially for the above-mentioned product lines. In Sweden, forestry is of major importance and the Swedish economy and standard of living have mainly been created based on the revenues generated from it. Thus, it is vital that Swedish forests are harvested in an efficient and responsible manner. The demand for biofuel is growing and today accounts for 15% of total Swedish energy production, a share that will probably increase. This study is based on three research questions, which are described under the heading of Aim. The results reveal that the most profitable method for handling forest fuel is the traditional one, which is also the most commonly used method in southern Sweden, namely the stockpiling of logs in a clearing by means of forwarders followed by splintering at the place from where they will be distributed. Today, the high cost of barge transport required for the extraction of forest fuel in an archipelago environment renders such operations unprofitable.

Timmerlängder till Iggesunds sågverk

Det råder hård konkurrens på marknaden för sågade trävaror. Längdkrav på furuprodukter var tidigare sällsynt men blir allt vanligare. Idag efterfrågas längre och längre längder, helst ska sågade trävaror vara över 42 dm (vilket motsvaras av timmerlängder över 43 dm). Iggesunds sågverk ställer sig frågan om det finns möjligheter till en bättre längdanpassning av sågverkets timmerlängder till marknadens krav, och om en sådan förändring skulle löna sig? Detta arbete tittar på tre scenarier till förändrade timmerlängder och hur de påverkar Iggesunds sågverks lönsamhet.

Uppdatering av båtnadskalkyl med hänsyn till nya faktorer :

Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.

Den mobila arbetsplatsens måltid : lastbilschaufförers upplevelser av mat, måltider och stress under arbetstid

Syftet med studien är att undersöka lastbilschaufförers syn på mat och måltider. Vad de värderar i val av mat och måltidssituation och vad som påverkar hur måltiden genomförs i det mobila arbetet. Vidare studeras hur mat- och måltidsvanor påverkas av den upplevda stressen och tidspressen i arbetet, samt strategier att hantera denna. Ett ytterligare syfte är att belysa arbetsledningens och fackets syn på och arbete med mat- och måltidsfrågor.Studien är kvalitativ, och semi-strukturerade intervjuer har genomförts, med fyra lastbilsförare och en transportledare/personalansvarig på ett åkeri i nordöstra Skåne, samt ett fackligt skyddsombud.De nyanställda och oerfarna förarna uppfattades vara mest utsatta för stressens negativa sidor. Med erfarenhet byggdes förmågan upp att hitta på sina körturer, och även strategier för att hantera och motverka stress på.
