Analys av värdeoptimeringen i justerverket : Rörvik Timber
I takt med konkurrensen ökar på marknaden väljer många sågverk att i allt högre utsträckning kundanpassa sin produktion mot de krav kunderna ställer på produkterna. Sågverkens produktion bör vara inriktad på att skapa ett så högt värdeutbyte som möjligt där virkets egenskaper och produktionsanläggningens förutsättningar ställs mot de kundönskemål som finns. (Lycken, 2000)
I sågverkets justerverk sorteras trävarorna i olika sorteringsklasser, även kallat kvalitetsklasser, samt kapas i exakta längder. För att kunna skapa ett högt värdeutbyte krävs det kunskap dels om vilka av träets egenskaper som är avgörande för värdet med dagens sorteringssystem och dels en insikt i hur volym- och värdeandelar ser ut för olika produkter samt hur olika sorteringsregler styr värdeutbytet.
Sedan början av år 2008 har Rörvik Timber Rörvik AB ett BoardMaster-system i sågverkets justerverk som använder färgkamerateknik för att värdeoptimera trävarorna. Examensarbetets syfte är att analysera värdeoptimeringen av trävarorna i justerverket vid sågverket i Rörvik.
Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad
This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..
Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft
Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.
Kostnadseffektiv minskning av koldioxidutsläpp från tunga fordon i Sverige :
When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.
Rekryteringsprocessen- ett hinder för jämställdhet? : En fallstudie av ett företag där kvinnor är underrepresenterade
Ur ett internationellt perspektiv anses Sverige vara ett jämställt land. Trots detta finnsen utpräglad könssegregering på arbetsmarknaden som ett resultat av traditionellaföreställningar om vad som är kvinnliga och manliga yrken. Träindustrin harhistoriskt sett varit en mansdominerad bransch och det är fortfarande svårt för kvinnoratt få anställning inom den branschen. Vid rekrytering av personal finns möjligheterför företag att förändra den demografiska strukturen hos arbetsstyrkan.Med denna bakgrund ämnade denna studie att undersöka rekryteringsprocessen ur ettjämställdhetsperspektiv på ett utvalt företag inom träindustrin. Företaget har delat insina anställda under två yrkeskategorier, tjänstemän och kollektivpersonal.Underrepresentationen av kvinnor är mest märkbar bland kollektivpersonal och därförstuderades skillnader i hur rekryteringsprocessen ser ut mellan yrkeskategorierna.Studiens resultat visade att jämställdhetsperspektivet inte beaktas i samtliga momentav rekryteringsprocessen.
Framtidens distributionslogistik : - Effekter av en ökad centralisering hos ABB i Västerås
Executive SummaryThis final thesis has examined the effects of an increased centralization and better coordination of the distribution logistics at ABB in Västerås. The company is today strongly decentralized and there is a minimum of collaboration between the 20 business units. This is why the questions were raised; how could the business units coordinate outbound logistic activities and what effects would that provide. The objective of this final thesis is to provide basic data for a future decision-making which describe these effects.The report has mapped out the factors that are important to ABB in an evaluation of their logistic activities and how the outbound logistics work today. The four factors are cost efficiency, delivery service, environmental impact and logistics capability.
Slumpmässig Informationssökning eller ?Jag talar hellre om inspiration?. Skådespelares slumpmässiga informationsanskaffning
The aim of this study has been to investigate actors? methods for acquiring information that is necessary for their profession, with a focus on the more random methods they might possibly use. The study is based on the following questions: What information needs do actors have in relation to their profession? Which methods do actors use to procure information? Which information systems do actors use? What role does the library play in the actors? acquisition of information? Through an interview study with 10 informants a picture is formed of the actors? information behavior. With the help of theoretical ideas regarding random methods of acquisition, we describe which information needs actors have and how they acquire that information.
Vad är strategisk rörlighet?
Strategisk rörlighet är ett begrepp som används frekvent i dagens moderna insatsförsvar.Men vad är strategisk rörlighet egentligen? Räcker det att införskaffa modernatransportflyg för att insatsförband ska ha strategisk rörlighet? Denna uppsats har till syfteatt visa på att strategisk rörlighet är ett komplext begrepp. Ämnet är angripet med ensystemvetenskaplig teorianknytning och genomförs som en kvalitativ deskriptiv metod.Den teknik som används för insamling av data är litteratursökning. Det är trefrågeställningar som behandlas: Är Sverige som nation i behov av förmågan och/ellerfunktionen strategisk rörlighet, Vad är strategisk rörlighet samt Finns det någon skillnadmellan funktionen och förmågan strategisk rörlighet och i så fall vad består den i?Strategisk rörlighet visar sig vara ett komplext begrepp som täcker ett stort område alltifrånvilka transportresurser som behövs, till att enheter behöver vara interoperabla för att intebara kunna transporteras utan för att kunna verka tillsammans med andra länders enheter.Resultatet är att Sverige är i behov av förmågan strategisk rörlighet, att strategisk rörlighetär ett system av transportkapaciteter, materiel och utrustning samt personal och kompetens,att strategisk rörlighet är en förmåga och inte en funktion..

Att skriva staden genom språnget : En undersökning av plankning och parkour som skapande, rumsliga praktiker utifrån Michel de Certeaus The Practice of Everyday Life
What happens when one moves about in the city? In this essay I will explore how we through our movements create our own temporal cities. I base my investigation on Michel de Certeau's theories from his book The Practice of Everyday Life vol 1. De Certeau believes that by just walking in the city ? a mostly unconscious and for many trivial activity ? you write it, creating different types of spaces that can be understood using linguistic terms.In my essay, I develop de Certeau's theories about ordinary activities by applying them to two less ordinary ? and between themselves quite different ? spatial practices: fare evasion on public transportation (plankning) and the urban activity of parkour.
Skånska trähägnader : en studie i konstruktion och historisk utbredning
The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
Obemannade markfarkosters militära nytta inom området logistiktransporter : En studie riktad mot Försvarsmaktens motståndarläge i Afghanista
Obemannade markfarkoster är ännu ganska ovanliga i den svenska Försvarsmakten men borde kunna bli allt vanligare. UGV:er används traditionellt till att utföra smutsiga, tråkiga och farliga arbetsuppgifter. Kan de då vara användbara i Afghanistan mot den motståndare som FM möter där idag?I studien undersöker författaren möjligheterna för obemannade markfarkoster att bidra med militär nytta inom området logistiktransporter. De obemannade transportfordonen kan från grunden utgöras av standardlastbilar i FM som har utrustats med så kallade UGV-kit.
Möjlighet till ett värdigt liv : Ett föräldraperspektiv på barns delaktighet och livskvalitet genom personlig assistans
The purpose of this study was to illustrate a parental perspective of children´s participation and quality of live through personal assistance. Important aspects of parents' experiences were highlighted based on how they experienced participation and quality of life for their children. We chose to use a qualitative approach in the form of four individual interviews with parents from different municipalities in central Sweden. The study was conducted with a narrative approach in which we used a holistic perspective. Parents' experiences were highlighted over time to create a complete picture.
Undersökning av Södra-transportörernas användande av KOLA-systemet
The purpose of this study was to create a picture of Södra´s round wood transporters usage, and positive or negative experiences of the KOLA-system. The KOLA-system, owned and managed by SDC, is a program for handling timber orders and displaying their locations on digital maps. The study was conducted as a twenty-three question internet-based survey. Of those asked to complete the survey, 57 percent chose to answer the questions.
The results of the study indicated that several of the transporters found the system quite good and used it to a large extent. The system also had many deficiencies however, and there was clear potential for further increasing the usage of the system.
Metod för urval av bäriga bestånd längs med bäriga vägar i Sveaskogs planeringsområde Råneå och Överkalix :
With increased need for flexibility in timber deliveries, forest roads become an important factor. The disintegration of roads during the spring season can be avoided if it is possible to rule cutting areas to stands with good carrying capacity along roads with good carrying capacity.
The goal with this work was to create a method to find the stands with high carrying capacity located near roads with high carrying capacity, and select them into a collection file. The method was based on Esri ArcGIS 9 and the tables that follow within that program.
The method resulted in four different themes:
1. Collections with GYL 100 that cross the bufferzon for 0, 1, 2 and 3 class roads. Result 36 collections.
2. Collections with GYL 100 and 200 that cross the bufferzon for 0, 1, 2 and 3 class roads.
