The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.

Med utgångspunkten att ständigt förbättras och öka konkurrenskraften arbetar Alfa Laval mot Leanprinciper. Vad som dock är ett problemområde är att se över fabriken ur ett helhetsperspektiv, närfabriken är uppdelad i många avdelningar. Lösningen till detta problem är att via olika metoder ellerverktyg kunna fastställa svaren på problemen.Denna examensrapport redogör för hur metoder inom Lean produktion kan vara lösningen förproblemområdet. Forskningen är huvudsakligen byggd på en bred värdeflödesanalys som syftar till attfånga in ett företags alla aspekter ur ett helhetsperspektiv, med syftet att minska risker försuboptimering och istället optimera produktionen som helhet.För att se gränssnitt mellan informationsflödet har i denna forskning metoden swimlane utgjort enkartläggning över ett företags hela kontorsavdelning, planerings och inköps avdelningar.Resultatet av denna forskning visar att värdeflödesanals är en bra metod för att kunna identifieraslöserier, ojämnheter i produktion, brister vid tillverkningen och flaskhalsar. För att sammankopplaolika avdelningar av ett företags informationsflöde, visas i resultaten att swimlane är en bra metod försyftet..

In the digitized world many organizations experience a large flow of information. To sort and manage all the information can be difficult. Individuals may experience a phenomenon called ?Information Overload?, due to the fact that the information flow is too extensive. There are various reasons why individuals are affected by this phenomenon.

This essay is a case study carried out at Flow Systems Ltd that foremost aims to treat the internal marketing at the company. The aim with the essay is to analyze and evaluate Flows internal marketing in connection with a process of change and how this reflects the external marketing in relation to customers.The method that has been used is qualitative in the form of depth interviews carried out with management, employees and customers. This type of data was chosen since it is a good way of gathering more specific information regarding the informants preferences about the company. Among other things the results of the interviews showed internal marketing deficiencies, but that has not influenced the customers in a negative way. The conclusion was that the inferior internal marketing does not affect the cooperation and the communication between the company and its customers, however it has a big effect on the employees..

There is no well-organised warehouse layout? There are no routines to keep the warehouse clean and in order? There is no formed plan how to handle materialTo solve these problems we have used different methods like interviews,observations, calculations and literature studies.

Concrete is a very common construction material. It´s characteristics are strength, durability and formablility. Superplasticizer is a common admixture, which changes the properties of concrete. Today (spring 2007) there are no certian mathematical methods to calculate the required percentage of this admixture needed to give the necessary set slump flow in the overall concrete recipe. Concrete batching companies must therefor experiment with different amount of superplasticizer in order to meet the specified slump and strength. The purpose og this report is to investigate if any mathematical relation can be established between the amount of superplasticizer used and the slump flow achieved. After carrying out some practical experiments using four different superplasticizers a direct relationship can be establish between the percentage of admixture used and the slump/flowability achieved. Unfortunatly at present due to the numerous variables, the calculation of mathematical formula can not be achieved..

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.

The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.

We have left the industrial society, and instead, we live in a post-industrial knowledge and information society. It is often said that industrial production has disappeared or that it has changed greatly. This means that fewer are employed in the manufacturing sector while the service sector is increasing, resulting in that the boundaries between production and administration decreases. The production goes from mass production to more flexible and specialized solutions. This puts greater demands on the logistics chain that continually need to work to meet customer requirements.

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

In a time when milk producing farm businesses face decline in profitability it is of great importance to examine how the situation can be improved. This thesis is a study off efficiency in milk producing farm businesses represented by Swedish, Dutch and German farms. The aim of this study is to investigate whether any differences exist between companies in these countries. Moreover, the study includes a mapping of a number of factors that determine how efficient milk production can be managed. This mapping is based on a literature review on prior efficiency studies followed by qualitative interviews with milk production advisors as well as a questionnaire sent out to dairy farmers in Sweden.

Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.

The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..

In the year of 2009 the conditions for managing primary healthcare in the region of Västra Götalandchanged. The decision was taken by the regional assembly and resulted in that the citizens since thenhave had the opportunity to choose which health care provider they preferto stay with. Along with thisdecision a new market for private health careproviders was established, which resulted inincreasedcompetition between the providers.In order to manage the competition, the health care providers arenow forced to be more efficient in their operations andalso to beeven more focused on their patients.Backa Läkarhusgruppen is an example of a private healthcare provider in the region of Västra Götaland.In the same way it is also an example of anorganizationin need of analysing their operations to seehowit can be further optimized to meet patient needs and expectations.The aim of this study is to analyse Backa Läkarhusgruppen?s organization and its operationsin the hopeoffinding suggestions whichwill improve the patient flow.To allocate and solve the problems thatBacka Läkarhus suffer from,an approach inspired by Lean Healthcare is used throughout the report.Some of themost significant problems that were identified within the organization are:?The synchronization of demand and capacity is inadequate.?Absence of standardized routines.?Absence of present leadership.To be able to improve the patient flow Backa Läkarhus needs to handle these identified problem areas.By synchronizing the staffing level in relation to the trends in demand a reduction in the patient?swaiting times and throughput time will be possible. Creating clear responsibilities and routines for thestaff will contribute to a higher degree of patient focus and thus lead to a more efficient patient flow.

A district heating plant has the advantage that it can take advantage of the waste heat from industries and use of cheap fuels to produce heat. But for the long term is competitive requires that energy is also saved in district heating plants. One way to save energy in a district heating system is to increasing cooling to the return temperature. This leads to less power needed to drive the distribution pumps,  and that more energy could be extracted from the same amount of fuel by an improved flue gas condensation.In Karlskoga the return temperature into the district heating plant is high. They would therefore reduce the return temperature in order to extract more energy from the flue gases.
