The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.

AbstractIt is important to choose which spare parts to keep in stock. With the right spareparts in stock the costs for inventory and production loss will decrease. Cavalieri et al. (2008) highlights that the balance between inventory cost and production loss is underestimated.  It affects the company and must be considered before decision on purchase.The problem with spare engines is that they are all more or less critical for the production. That can be a reason for why no previous research targeting engines and classification of with engine should be kept in stock has been found.

Background: outsourcing is one of the most obvious and continuous trends that has been able to study during the past ten years and also has had a strong development in the industry. What consequences will follow from an extended outsourcing? Purpose: the study?s overall purpose is to investigate what possibilities and risks that can be connected to an outsourcing decision and how the order of the service will handle the risks. The study will also investigate what management philosophy that will be used and regulate the outsourcing relation and how the company?s strategy will affect the decision and how the process of outsourcing will look like.

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

Background - Swedish trade and industry primarily involves small corporations, including small manufacturing corporations. Currently, most costing models that are used are based on studies accomplished at large corporations. This conveys to the fact that product costing that occurs at small manufacturing corporations is based on all complexities that large corporations bring, which rarely match with small corporations. It occurs that small manufacturing corporations unconsciously rely on incorrect information that has been calculated based on great corporations? product costing.

AbstractToday there is an opportunity to reinforce concrete with steel fiber reinforcement. In some cases, completely replace the conventional reinforcement. Replacing conventional mesh reinforcement with steel fiber reinforcement in slabs on ground has shown economic benefits, less crack width and less reinforcement amount.Today there are no Swedish standard for designing steel fiber reinforced concrete, what is there is different international recommendations.In this work, design methods for steel fiber concrete are used according to RILEM and Bekaer Swedish AB's software DRAPRO. For other design methods Eurokod 2 is followed.In this work, the design of slabs on ground that are not exposed by large tension strength been designed. Design of crack-reinforcement and restrictions of crack width have been conducted in three different slabs on ground.The calculations have been performed using only conventional reinforcement and only steel fiber reinforcement, and the results are then compared.The results of the theoretical analysis are summarized in tables that compare the amount of reinforcement, crack width and economic cost.This work showed that the slabs on the ground reinforced with steel fibers provide less crack width with a minor amount of reinforcement.

The main purpose of the essay was to evaluate whether investments in index-linked bonds were suitable investments for smaller investors on the international finance market. To determine whether the index-linked bonds are good investments, the variables yield, cost and risk were used to measure the index-linked bonds against investments in stocks and funds. The reason for the interest in this subject is that investments in index-linked bonds have grown furiously the last few years. With the growth of the investments the criticism of index-linked bonds has also grown stronger. The critics? main point is the cost of the product, and they imply that investors can create their own index-linked bond and thereby avoid the bank fees.This study used a quantitative approach, because all the data of yield, cost and risk consist of numbers.

The purpose of this thesis is to find means of control that secure cost efficiency regarding the accommodation for the employees on missions abroad of the Swedish Ministry for Foreign Affairs. Today the ministry?s cost for the employees? rented housing is 100 million SEK and there is a need of improvement in the control of these costs. A work method for organizational development will be used in order to reach the findings presented in the thesis. First we study the strengths and weaknesses in today?s control system.

According to the European Union waste hierarchy, waste should first of all be minimized. Reuse and material and energy recycling come next. Lastly the waste should be thrown at the refuse tip. In the inner city of Stockholm waste handling can be done in various types of ways. The solutions vary as a result of the type of architecture of the building and its condition.

The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.

The background of this study is the fact that it nowadays is more common to grow wheat after wheat. Usually we plow every autumn to remove the straw, and we wanted to study the effect of alternative methods to do it. We have done this experiment to answer the question if no tillage is better than conventional plowing. The results of the field experiment indicate that there is a link between plant establishment and the choice of equipment, but also a higher weed pressure in experimental plots with only ground tillage. The equipments which left much straw on the top of the ground the problems with fungi were more severe.

This study concerns mapping and analysing two different Supply Chains at Setra Group. Setra Group is Sweden?s biggest producer of solid wood and is primarily owned by Sveaskog, Mellanskog and LRF. The Company consist of twelve sawmills, five planning mills and an organisation for distribution of building material. This study maps one chain for Swedish Glulam standard beam and one chain for solid pine flooring on export to Japan. The glulam chain is based on spruce as raw material and includes all actors between sawmill and the Swedish building material retailers.
