Efterfrågan av grova sågade dimensioner och hyvlade produkter bland Wallnäs AB:s kunder : en marknadsundersökning
The purpose of this thesis is to study whether there is a demand for sawn wood products of large dimensions and planed goods among Wallnäs AB:s customers. The thesis consist of two main parts, one survey among Wallnäs present customers and another one which purpose is to increase Wallnäs customer base. Finally there is a chapter that describes what properties the raw material has to have in order to produce the demanded products.
The survey to the present customers was conducted through a questioner. A sample of those who stated an interest for either sawn wood products of large dimensions or planed goods, were later contacted for a telephone interview.
To reach out to new customers, relevant companies has been identified through the Swedish Trade Councils data base and through the member list of the Timber Trade Federation.
Bevattning av lagrat virke vid svensk skogsindustri : omfattning och miljökonsekvenser
Most of the saw and pulp industries have stored wood nearby their production, the main
reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality.
One drawback of wet storage of wood is the leaching of chemical substances into the
surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and
organic substances. These substances can cause problems for the surrounding environment.
The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.
Effekten av demand-supply chain management : Fallstudie från trävaruindustrin
Enligt Carlsson och Rönnqvist (2005) och Frayret et al. (2007) blir det allt viktigare att arbeta med supply chain management inom trävaruindustrin. En utmaning är att finna ett arbetssätt för att hantera variationen i kundens efterfrågan. Idag hanteras variationen oftast genom onödigt stor lagerhållning (Lee et al., 1997b; So och Zheng, 2003). Syftet med studien är att utreda påverkande faktorer som bidrar till en varierande efterfrågan inom trävaruindustrin samt föreslå hur uppkomsten av dessa kan undvikas. För att svara på syftet har tre frågeställningar tagits fram och en fallstudie genomfördes på ett hyvleri.
Teknisk och ekonomisk analys av en bränslekonvertering vid SIA TallOils pelletsfabrik :
At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant
Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.
Liv i d?d ved: En unders?kning av f?rh?llningss?tt till d?d ved p? ?ppeltr?d i tr?dg?rdshandb?cker och bland yrkesverksamma tr?dbesk?rare
In this essay, several factors in apple tree care (specifically in relation to whether dead wood
should be kept or removed) are highlighted for example, aesthetics and biodiversity.
To present some background, the essay begins by introducing some previous literature on
dead wood. This leads into how dead wood is treated within forestry. Next, previous research
on dead wood in fruit trees is mentioned. Cultural and historical management methods are
also highlighted.
Skogsentreprenad idag och i framtiden : en kvalitativ studie av skogsmaskinentreprenörersverksamhet och framtidsvisioner
The Department of Forest Products and Management, Swedish University of Agricultural Sciences has received means from Vinnova for a preliminary study of the organisation of logging work of today and how a better logging organisation should be brought about. This thesis reports results from qualitative interviews with nine forest machine contractors regarding the situation of their companies. The interviews have been analysed with respect to the genesis of the companies, which tasks they perform or that they could consider perform-ing, business relationships of the companies, relationships between the different partners of the companies, and the state of competition experienced by the contractors. The companies have developed either from the contractor previously being machine operator employee or from that the contractor in making has owned a machine and needed work. Their primary business is mechanised logging.
Död ved i ett referensvattendrag
The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout.
The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.
Effektivisering av informationsöverföringen i läkemedelskedjan
This report is the documentation of a project in the education Master of Science in Mechanical Engineering. The project was carried out at Alfakonsult AB. The purpose of the project was to map out the transference of information between the different operators in the supply chain of medicine in Sweden and to analyse this in order to reduce lead-time and the total throughputtime. The supply chain of medicine in Sweden consists of producers, distributors, one wholesaler, prescribers and patients. The mapping of the transference of information showed that most operators in the supply chain have done well introducing technical aids to facilitate the transference of information.
Mot en hållbar e-livsmedelshandel : En kvalitativ studie av svenska e-livsmedelsaktörers initiativ för Sustainable Supply Chain Management
Den växande e-livsmedelshandelns Supply Chains har studerats genom hållbarhetsglasögon där syftet var att ?[?] ge en fördjupad förståelse över hur svenska elivsmedelsaktörerarbetar med frågor rörande Sustainable Supply Chain Management?.Syftet fullgjordes genom en kvalitativ studie av tre organisationer, i vilka totalt 9 beslutsfattare intervjuades enligt ett semi-strukturerat intervjuförfarande. De data som samlades rörande e-livsmedelsaktörernas arbete med SSCM har i sin tur analyserats med hänvisning till en i förväg fastställd teoretisk referensram.Vår studie avslöjar att två av de svenska e-livsmedelsaktörerna är exemplariska och framstående med att införliva hållbarhet i sin Supply Chain. De engagerar sig aktivt i de initiativ för Sustainable Supply Chain Management som i litteraturen identifierades som nödvändiga för en verkligt hållbar Supply Chain. De har en allomfattande och övergripande strategi för att minimera den sociala risken, reducera resursutnyttjande och förorenande biprodukter i hela Supply Chain samt för att förbättra organisatoriskt inbäddade ohållbara vanor.
En jämförelse av skogsmarksprisets utveckling mellan Sverige, Danmark, Norge, Finland, Estland och Lettland
During the twenty-first century the price of forest land in Sweden has increased heavily. Buying forest land has become more common and the stakeholders have grown in number.
The countries around Sweden have through the globalization become connected in the market of round wood and wood products. The price of forest land and round wood are also close connected.
The goal with this report is to make a comparison of forest land prices between Sweden, Denmark, Norway, Finland, Estonia and Latvia and to see how the prices have developed in the period 2000-2011. The prime factor in the comparison, except the direct price difference between the countries, is the round wood prices. The round wood prices give information about the economic situation in the countries and play an important role in the return on the forest land.
The prices of forest land shifts heavily between the countries.
Pelletskvalitet : Test av olika råvarumixer i pelletstillverkningen vid Rindi Västerdala AB:s bioenergikombinat i Vansbro
Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.
En lyckad affärsrelation? : två fallstudier
This study has investigated what makes a business relation satisfactory. The purpose is to distinguish the factors that are relevant to a functioning cooperation relationship between sawmills and DIY-stores. The theoretical framework is primarily based on long-term business relationships. The study is based on two case companies and their relations with wood-suppliers.
- Case company 1 is a relatively new established and still growing company.
A Strategic Decision-Making Model for Supply Chain - A Void to be Filled
Many researchers emphasize the increasing strategic importance of supply chain management, but there is still a lack of concrete guidance for managers faced with strategic decisions in supply chain. Within decision-making theories, the rational decision-making model is the most commonly used. This because of its suitable foundation, enabling a structure to the complex decision process. The rational decision-making model is today not developed to include the aspects of strategic decision-making made in supply chain. The purpose of this research is to adjust a structured rational decision-making model, making it applicable for strategic decision-making in supply chain.
Centrala logistiska faktorer i en förädlingskedja för massproduktion av träpellets : Fallstudie på Kopparfors Pelletsfabrik
This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.
Lönar sig Supply Chain Management för mindre företag?
Purpose - To analyze the relationship between supply chain management maturity, supply chain performance and financial performance in small and medium-sized enterprises (SME:s).Design/methodology/approach - The data comprises 15 SME:s that participated in a local logistic study in Gävleborgs län. The levels of supply chain mature within these firms were based upon an interview study and the financial performance of the firms was then examined using financial reports-based data.Findings -The results of this study indicate that there is a strong relationship between SCM maturity and SC performance in SMEs, some relationships between SCM maturity and financial performance, as well as some relationships between SC performance and financial performance. This means that if firms use maturity indicators in the SCOR areas to improve their processes, they will most likely achieve a positive effect on supply chain performance and probably also on financial performance. The result implies that the supply chain maturities in these firms are higher than expected with no one at the adHoc level.While this study is based on a rather small number of participating firms, it would be valuable to further test the significance of the indicated correlations between SCM maturity and performance in a large-scale survey.Research limitations/Implications - The research is an attempt to understand supply chain maturity and it´s implication on financial performance. Developing supply chain maturity is an opportunity for a company to gain superior performance.
