The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.

The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.

Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.

Considering that the current technology is constantly improving, it becomes increasingly important to have an efficient logistics in a company to maintain profitability while achieving a competitive business. Efficient logistics may be accomplished by improving the internal materials handling. In this thesis the internal material handling of steel frames has been studied at a factory in Vaggeryd. The goal of this study is to investigate the problems that exist with the current production flow of products and provide suggestions on how it can be developed to reduce unnecessary handling and movement.The study has a deductive approach where the authors has been using literature studies parallel with empirical analyzes conducted at a company to achieve the purpose of the study. Documentation from the company and interviews with staff and observations form the basis for the data collection carried out.

I takt med att besökare och patienter ökar måste kontinuerligt Östra sjukhuset verksamhet utvecklas. Detta medför omläggningar i trafiken och förflyttningar av verksamheter. Idag finns flertalet brister kring Östra sjukhusets fysiska planering som behöver ses över, dessa är bland annat trafikflöden, säkerhetsaspekter och parkeringsmöjligheter.Rapporten redogör för förändringar i den fysiska planeringen som förbättrar dess utformning. Genom studier av relevant litteratur och diskussioner med expertis har förslag av problemområden tagits fram. Dessa har sedan bedömts efter listor av deras respektive för- och nackdelar som kunnat urskiljas.Arbetet visar framtagandet av ett väl fungerande förslag som kan verka som en bas för idéer till nutida och framtida förändringar kring den fysiska planeringen.

I planeringssammanhang är det vanligt att tala om en attraktiv stad, men begreppet är svårdefinierat. Dels därför att det är starkt kopplat till individens egna värderingar, men också därför att begreppet består av många faktorer. Det är därför praktiskt omöjligt att utforma en attraktiv stad om inte begreppet attraktiv stad definieras. Det finns många teoretiker som forskat inom området, genom olika tidsepoker och med olika infallsvinklar. Trots den allomfattande forskningen finns det idag ingen enskild teori eller definition på vad som utgör en attraktiv stad. Examensarbetet har lett fram till en undersökning av begreppet attraktiv stad, som sedermera lett fram till olika faktorer och beståndsdelar som bygger upp definitionen attraktiv stad.

The Swedish government has proposed that 20 % of the cultivated land in Sweden should be organic by the year 2010 (The Swedish Board of Agriculture, 2008). In addition to this the production of organic food like milk, meat and egg should increase considerably. To reach the government?s goal it is necessary that the Swedish farmers get motivated to convert their production from conventional to organic. Milko is a dairy association that has chosen to focus on organic products, they want to be the leading organic dairy association, and therefore they have a large need for organic milk (Milko, 2008).

Begreppet hållbar utveckling har växt fram kring orsaker och lösningar för globala försörjnings- och deponeringskriser. Begreppet är mycket brett och diskuteras runt om i världen. Diskussionen om hur samhället ska uppnå en hållbar utveckling har påverkat fysisk planering och trafikplanering. Grunden till en hållbar utveckling ligger i en samordnad och miljöanpassad bebyggele- och trafikplanering. Det är bland annat viktigt att det finns förutsättningar för en effektiv och miljöanpassad kollektivtrafik och ett effektivt gång- och cykeltrafiknät.

The thesis work was conducted with the company Free2Move AB. The company is located in Halmstad and is an acting provider of wireless communications for industrial customers, mainly focused on Bluetooth? technology.In today's society most people have their music on their computer, MP3 player or mobile phone. What if you could avoid the cable between your sound system and sound source and transfer music wirelessly instead? Together with the company's engineers, I have developed a new comprehensive product for wireless music transmission.

The work with this report has been focused on developing a methodology model for control at purchase. The methodology model covers parts classification, dispatching systems, batch shaping and more. The aim with the methodology model is that it will be used as an aid for a cost effective material planning to increase the value for customer.The work covers also a description of the present situation and the purchase process at Company X. Six parts have been applied, two from each class (A, B and C), in the methodology/model. The parts that have been applied are included in the flow between Company X and their supplier Company Y.Data have been collected trough literature studies, interviews and the company?s business system.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.

Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased. As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.

This study analyses the economic consequences due to ethanol production in Eastern Sweden. The analyses consider the cooperative and the farmers as one vertically integrated company. The area that found the market in this study is illustrated in figure 1. The analyses assume that all members act jointly with the objective of maximizing joint profits at the farm level as well as at the cooperative firm. A mathematical model is created to calculate the optimal use of arable land.
