Kvalitetssäkring av servicelämnare för skogsbrukets arbetsmaskiner : Intervjuer och förslag till utveckling

In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..

Utveckling av logistikflöde : En undersökning av införande av extern kittning av hydraulslang vid Komatsu Forest AB

Komatsu Forest AB tillverkar skogsmaskiner och aggregat. I monteringsprocessen är hydraulslangar en av komponenterna som hanteras och lagras per artikelnummer. Idag genomförs intern kittning då slangar plockas ur respektive lagerlösning mot en specifik monteringsoperation. Kittning innebär att delar och komponenter sorteras i set, så kallade kit, innan de levereras till monteringsoperationer. Genom extern kittning som utförs av leverantören kan eventuellt flödet av hydraulslang och utnyttjandet av ytan i anläggningen bli mer effektivt då kitten är färdiga när de anländer till anläggningen. Syftet med arbetet är att identifiera det mest produktiva och kostnadseffektiva arbetssättet gällande hantering av hydraulslangar från beställning till montage på maskin.

Utvärdering av traktplanering på Holmen Skog

This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

Miljöhänsyn vid offentlig upphandling :

One of the biggest challenges in the human history is to prevent environmental pollution. Everybody has an indirect or direct influence on the environment through his or her consumption. The stakeholders are not just interested in price and quality, they are also interested in the circumstances of production and how this affects the environment. By taking environmental concern in public procurement it is possible to speed up the environmental adjustment of services and products. Environmental awareness has become more and more self evident in the environmental work.

Koldioxidsutsläppsbesparing vid biogasproduktion

Society has depended on fossil-based fuel for a long time, which has led to a fundamental increase of greenhouse gases in the Earth?s atmosphere. To tackle this problem the international community has agreed that action is necessary. Focus is now directed towards local extraction of energy from renewable sources such as biogas.Utö is participating in the Green Island project, which aims to investigate the possibility of making the island climate neutral. This report has been implemented on behalf of Skärgårdsstiftelsen, the main partner responsible for the Green Island project in Sweden.

Alternativa Drivmedel som Enhetsdrivmedel

Fossila drivmedel står idag för en överlägsen majoritet av den totala användningen av drivmedel som dagligen förburkas. Alternativ till de fossila drivmedlen krävs för att säkerställa tillgång i framtiden. Försvarsmakten har fått uppdrag från regeringen att utforska möjligheten att övergå till att driva sina fordon på förnyelsebara bränslen.Militära organisationer strävar efter ett enhetsdrivmedel, alltså ett gemensamt drivmedel som driver samtliga fordon och enheter. Största anledningen är den förenklade logistik som kan uppnås om endast ett drivmedel används.Detta arbete har sökt efter ett alternativt drivmedel som skulle kunna användas som enhetsdrivmedel inom Försvarsmakten. Detta för att lösa problematiken med att både byta till ett förnyelsebart drivmedel och ett enhetsdrivmedel i samma fas.Slutsatserna som dragit i detta arbete är att FT-bränslen har potential att användas som enhetsdrivmedel ur ett tekniskt perspektiv.

Älgbetesinventering på Orsblecks viltvårdsområde

The purpose with this report is to compare moose browsing in young stands within a small game preservation, and if there are any differences between two areas. The method used in the inventory is a local damage caused by moose browsing survey. It is suitable on areas that have more than 50 hectares but less than 250 hectares of young forest. Inventory of moose browsing is best done on bare ground in the spring and should preferably be done before the flushing begins at the pine. Orsblecks game management area is divided into two different moose management areas, Noppikoski and Siljansringen. During the winter Siljansringen has a denser winter strain of moose, because of the moose seek out lower parts with less snow during the winter. This should also lead to the southernmost part should accommodate larger proportion of damages caused by browsing by moose.

Bevarande av naturvärdesträd i enlighet med FSC och Holmen Skogs naturvårdspolicy :

In the end of 1998 the company Holmen Skog AB was certified accordint to the FSC system with an area of 1 036 000 hectare. After that Holmen Skog AB has been working actively with the nature conservation in the forestry. In order to control the quality of the company?s nature conservation in final fellings they started a yearly inventory which is called BAKRUS (Judgement of ecological and culture care in relations to policies for a persevering silviculture). After 1999 the control was expended to include all actions in the forest.

Konceptstudie av Waste Heat Recovery System på Tunga Fordon

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Ekoturism i jordbrukslandskap - ett vinnande koncept? : en tvärvetenskaplig studie om kulturvärden och naturvärden på Sjögetorp

Ekoturism har utvecklats som ett alternativ till annan typ av turism, med inriktning på att undvika negativa effekter på lokala ekosystem. I Sverige finns ekoturism som bedrivs i relativt orörda naturmiljöer, men också ekoturism som bedrivs i miljöer som påverkats av människan på olika sätt och som rymmer både kulturvärden och naturvärden. På gården Sjögetorp i Östergötland bedrivs ekoturismverksamhet i familjeföretaget Urnatur. Mitt syfte med studien var att undersöka vilka kulturvärden och naturvärden som finns på gården idag, och hur dessa värden hänger ihop med ekoturismen. Jag genomförde en inventering av hela fastigheten där jag registrerade ägoslag och strukturer viktiga för kultur och naturvärden. För mer information om gårdens skötsel och ekoturismverksamheten intervjuade jag ägarna. Jag undersökte också historiskt kartmaterial för att kunna sätta gårdens skötsel idag i perspektiv till hur jordbrukslandskapet sett ut historiskt. I min inventering dokumenterade jag många olika typer av naturvärden, bland annat död ved i många former, hamlade träd, slåtterängar, betesängar och skog skött till förmån för lövträd. Kulturvärden som fanns var ofta kopplade till naturvärden, som till exempel slåtter, hamlade träd och skogsbete.

Alternativa drivmedel i den svenska vägtrafiken år 2030 : En utvärdering av den svenska regeringens målbilder

The Swedish government has set up the overall goal that no net emissions of greenhouse gases can occur after 2050. A sub-target has been developed for road transports which states that the use of fossil fuels must be reduced with 80% to 2030 in order to be completely abolished to 2050. A public inquiry mapping how this can be achieved was handed in to the government late in 2013. The use of alternative fuels for road transport, both biofuels and electricity, is expected to give the biggest contribution to the reduction of the use of fossil fuels. The inquiry sets up a number of goals for how much the use of alternative fuels must increase to 2030 in order to reach the overall goal and which instruments that are needed in order to do so.The aim of this thesis is to evaluate how these goals can be reached and what the most likely obstacles that may hinder the reaching of these goals may be.

Strategisk/taktisk vägplan :

The purpose of this thesis was to create a strategic/tactical road access plan. This was done by designing an analytical method which gives the road manager a template to create long-term road access plans. The analytical method will help to identify and appraise roads to be upgraded and give information when it is time for building new roads. The study method involved developing an analytical method. The method was comprised of five main parts: the harvest plan, analysis of the road network, transport costs, quality and storage costs and finally, identification of investment alternatives.

Det svenska jordbrukets framtid :

The Common Agricultural Policy the European union´s common agreement about the agriculture financial support. A major change is about to take place in the next 3 years. This reform affects the first 15 members as well as the 10 new members in CAP2. This study contains a future of how agriculture will look like in Sweden in 10 years. The study is mainly based on interviews with key-persons3 in Sweden. The first part describes the CAP-reform in theory, the second part the interviews and the last is a conclusion of the material. The future will see larger farm units.
