The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.

Although Lean has received an increased amount of attention in the service context, research still has not established how successfully Lean manages to increase service productivity; since service productivity consists of both efficiency and quality. Research regarding productivity discusses the risk of a tradeoff between efficiency and quality in service production processes. Therefore, this thesis aims to explore if the tradeoff in a production setting with low variability in demand and low customer participation exists, after Lean has been implemented. With a qualitative approach, a case study has been conducted at Scandinavian Airlines Ground Handling to evaluate the effects of Lean in the baggage handling process. The result of the study shows that the tradeoff has not been overcome; efficiency has increased at the expense of quality.

Service quality occurs in service encounters where both customers and employees come together in an interaction. It is therefore important that the staff give their best because the interaction usually takes place in real time, which is referred to as the moment of truth.The aim of this study was to find out how luxury hotels are working to ensure good service quality, and how the staff are motivated to deliver this service. We wanted to examine this from a management perspective, and an employee perspective. Information was gathered through various interviews, where the staff at the Hotel Kämp in Helsinki and at the Sheraton Hotel Stockholm participated.Survey results show that employee motivation, training and empowerment have a significant impact to provide service in high quality. The results also show that the surveyed hotel, to certain level work in the same way, but it reveals some differences even when both hotels are part of the same concern..

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.

During its lifetime, a road goes through a number of different stages; pre-study,inquiry of the road, work plan, documenting stage, building stage and operatingstage. The operating stage is the one that takes the longest time and costs themost. Those have a tendency of becoming unnecessarily high because the projectengineers don?t always take the management and maintenance prerequisites intoconditions.To decrease the management and maintenance costs, the Swedish RoadAdministration SouthEast has been in need of a work procedure that makes theroaddesign engineers take the management and maintenance of the road intoconsideration. This shall be achieved by a checklist where the most commondesigns that lead to increased management- and maintenance costs are compiledand listed.Through interviews with project leaders in management, the most commonproblems have been identified, analyzed and summarized under the headlineswinter-road, vegetation, road equipment and road designs.To elucidate the problem from several points of view, interviews wereimplemented with project leaders in investment and roaddesign engineers.

Purpose: During the last years Real Options have been established in many areas of the day-to-day business. Recent literature also tries to address Supply Chain problems with option theory, since an efficient Supply Chain increasingly gains in importance as a significant competitive advantage. This thesis tries to answer the question, if Real Options can mitigate the costs induced by the Bullwhip Effect as one of the major problems in Supply Chains. Methodology: The authors of the thesis used a deductive approach. Based on a theoretical model utilizing Real Option contracts and under the usage of a randomly created dataset the influence of the Bullwhip Effect on the company?s business and financial structure is examined and subsequently analyzed.

Because society?s demand for quality, efficiency at low cost is constantly increasing, companies are increasingly choosing to invest new methods to achieve these points. Those who manage to find ways to improve their processes are often the companies that have the greatest chance of becoming a winning player in the market. BIM is a new method that can reduce the internal costs while increasing communications between different parties. However there is disagreement about what BIM is and its purpose.

Considering water quality, landuse and reducion of wetland area in the watershed of Tidan, areas witch are in need of constructions to improve the water quality are identified. Constructions are suggested to be located within the smaller streams in the watershed, so that the water is treated before it reaches the stream Tidan..

Multiple factors are involved in control of beef sensory quality so great variation can be induced. The perception of meat quality can be affected anywhere in the product chain. Both the environment and the set of genes of the animals have an effect on the final output. A problem facing the beef industry today is the significant variations in meat quality between individual animals, which is reflected in the uneven quality of the meat that reaches the consumer. If the quality of meat in stores varies significantly over time, the consumers? trust may decrease.

The distance between home and work has increased in recent decades. By the development of infrastructure and public transport, jobs farther from home have become more accessible and this development has in turn increased commuting. Commuting travellers often pass over administrative boundaries which often serve as borders for public transport pricing. Also the market control prices. Research shows that travel times and costs significantly affect commuting choice.
