Avvägning mellan ordersärkostnad och lagerhållningskostnad i processindustrin
Lean Production is used by many manufacturing companies. Companies in process industries do not use Lean Production to the same extent today. This is part of the report's issue to explore how Lean Production can be applied to a company in the process industries.The investigated company is a processing company that manufactures various types of foil. The company wishes to streamline its production and has therefore asked the authors to examine if Lean Production can offer the company improvements in their production. Lean Production value stream mapping tool has been selected to identify and analyze the current state of two of its products in production.
Mätsystem för effektförluster i en högfrekvenstransformator
To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.
Utvärdering av ett optimeringsprogram för produktionsplanering.
The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .
Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet
Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.
Energieffektivisering i sambandmed renovering : ? Analysmodell för energibesparande åtgärderutifrån ett företagsekonomiskt perspektiv
Rising energy prices and higher energy demands have led to an increased focus on energy efficiency, in particular in the real estate business, where high potential for energy savings exists. Within the next few years, buildings that were constructed in the sixties and seventies will be in need of renovation. One of the challenges of these renovations will be to improve energy efficiency. A real estate company that is facing this challenge is Uppsalahem AB, based in the city of Uppsala, Sweden. This study focused on analyzing energy efficiency measures when renovating old buildings.

This report is a study made at Pallco AB. Pallco is a subcontractor that is specialized on steel and aluminium components.The aim of the report is to show an improvement proposal that leads to a reduction of the storage and improve the flow through the production of one item that is a part of a product that Pallco manufactures.With the increasing competition from other countries who can manufacture with lower costs must Swedish companies try to make theirs manufacturing as efficient as possible and remove all waste. By using the tools of Lean Production it is possible to reduce the costs and increase the efficiency.The method we used is value stream mapping. A map of the present condition has been made and then different improvement proposal were discussed. A map of a future condition has also been designed..
Utvärdering av produktionsledarens användning av Holmen Skogs datorbaserade stödsystem vid operativ planering av avverkning
The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems.
The aim of this study is to:
? investigate the work pattern of the production managers when using the information system to plan the harvesting operation;
? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system;
? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern;
? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion.
The conclusions of the study were:
? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning;
? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information;
? the computer systems are however divided in many subsystems.
Sammanställning och produktion av ritningsunderlag till båt
Hanterbara båtar is a new company who builds alumina boats customized for people in wheelchairs. Due to the fact that the company only built two boats yet, the production documentation is not complete. The drawing that does exist is not in an exact standard which makes production planning harder.The purpose of this work has been to make the production of the boat easier and simplify further development and modification. Product development in the form of optimizing details is also one of the main purpose of this work.This is all done by making a 3D-assembly of all the existing drawings. After this is done new drawings will be made and added to the main assembly.
KappAhls sociala ansvar. Hur ser det ut i verkligheten?
With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.
Nyckeltalet - en studie av effektivitetsmätning i insamlingsorganisationer
The study examines how efficiency and effectiveness are measured in charity organizations in Sweden. The rules of Svensk Insamlingskontroll, Årsredovisningslagen and Bokföringslagen make up the accounting framework upon which efficiency and effectiveness are measured in charity organizations. The study is based upon interviews with the sector's main actors: Svensk Insamlingskontroll, Frivilligorganisationernas insamlingsråd, auditors and the charity organizations themselves. The interviews are supplemented by studies of the guidelines issued by Svensk Insamlingskontroll. Today's measure of efficiency is the percentage of a charity organization's income that benefits their goals, called nyckeltalet.
Biogasprocessen : Bestämning av verkningsgrad
Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.
Utveckling av en ny tillverkningslina
This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.
Slöserijakt i betongdjungeln : En tidseffektivisering av monteringsprocessen inom stål- och betongprefab
The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.
