Flödesanalys av plåtsammansättning : Strävan mot Just-In-Time och minskat slöseri
The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.
"Man vet inte vad man inte vet". En studie av informationsflödet inom Gatukontoret i Borås Stad
The aim of this thesis is to examine the flow of information in an administration of the municipality Borås Stad. To achieve the aim the following questions were asked: How accessible is information? How is information used in the organisation? How is information communicated? Totally sixteen qualitative interviews was accomplished with employees at the administration. The results of the interviews show that there is a difference in how much and what sort of information the respondents use. They all seem to prefer information to be communicated face to face if possible or over the phone.
Ökat flöde genom timmersorteringen vid Ala sågverk
Ala sawmill in Ljusne, Hälsingland, has increased its flow through the sawing plant during the last couple of years. The problem now is the sorting plant, as this part of the mill is now slower than the rest. A close analysis of the sorting plant was therefore necessary to be able to increase the flow through. The aim of the project was to find solutions that can lessen downtime and increase flow. The goal was to increase the flow from 650 to 925 logs through the sorting plant per hour.

Uppsatsen behandlar ämnet genus och genusframställningen i barnböcker nu, och för 50 år sedan. För att komma fram till ett resultat har två analysmetoder använts, Nikolajevas mimetiska metod samt en semiotisk bildanalysmetod. Resultatet visar att det skett en förändring av genusframställandet i barnböcker de senaste femtio åren och att den största förändringen skedde i mitten på 60-talet..
Val av teknik för hastighetsmätning i kallvalsverk
An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system. One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

Layoutförbättring på KSL Trading AB:s lager för skivmaterial
KSL Trading Inc is a trading company in the Jönkoping area that distributesmaterial for the furniture and interior design industry.The purpose of this report is to analyze the existing material flow andwarehouse layout as well as to identify the issues there are today at KSL?swarehouse for board material. When we identified what kind of problems thatexisted we were able to design a new plan for the material flow and storagepossibilities. The problems we found where:? 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.
Utveckling av Breakoutbox för Fuel Flow Transmitter
Development and construction of an electronic Breakout box is the main work for this thesis. The box is a part of a test system for the component Fuel Flow Transmitter and should convert signals to be suitable for a frequency counter. A previously constructed Breakoutbox for this purpose is being old and needed to be recreated. So SAAB Aerotech, Aircraft services, the company for the thesis work wanted to construct a new, more sustainable Breakoutbox adapted to a more modern technology. The signals to the box comes from the transmitter and should be converted to suitable signals for a frequency counter so it can show pulse and time difference between the signals.
Effektivisering av kundorderflöde : En fallstudie på BUFAB Bulten Stainless AB
We were commissioned by Bulten Stainless AB to identify and analyze their customer order flow. Because the company had problems with delays in the production and deliveries to the customer, the task also included investigation of how the company work with prevention and management of delays. The purpose of the project also included to identify critical factors for effective order flow in smaller workshop companies.The information about the flow and how the work takes place within the company were collected through observations on the company and interviews with the staff. This information was used to draw maps over the customer order flow and to write a description of the current situation within the company. Both strengths and weaknesses of the companies work could be identified through analysis of the present situation.
Råvaruinflöde inom träindustrin : En fallstudie på ett norrländskt pappersbruk
Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.

Sambandet mellan saldodifferenser och effektiva materialflöden : Fallstudie utförs på Atlas Copco?s logistikavdelning
Problems arise when the number of products in stock does not correspond with the number of products the information system says the company has in stock. (Sharda & Agrawal, 2012) In order to change that, major changes has to be made when it comes to making continuous improvements and to raise their standards regarding product availability and record inaccuracy (Wild, 2004).The purpose of this study is therefore designed to identify factors affecting the balance differences and what impact it has on the efficiency of material flow. The demarcation of the work is that Atlas Copco has begun working with Lean and it will not be investigated nor the relationship between balance differences and Lean. The study was based on answering the following questions: What influencing factors can be identified for balance differences? What factors are relevant to the efficiency of material flow? What kind of impact the balance differences has on these factors?In order to answer the purpose and issues, a theoretical framework has been developed with help of literature studies and an analytical model.
Effektiviseringsmöjligheter på Tunadals sågverk : med innesäljarprocessen i fokus
The investigation was initiated because of the high workload of the sellers and, additionally, because the Tunadal sawmill has received low ratings in customer surveys. Thus, two main approaches are adopted here, the first being to investigate which of the three methods of working, namely, market divided flow organization, function organizationand flow organization with collaboration, proves to be the most beneficial. The second is to investigate whether there is an available method to ease the daily work. A literature review has been made in order to determine more efficient ways for the sellers to work in the Tunadal sawmill. During the investigation, an in-depth investigation into the total quality management using a balanced scorecard as a management tool was conducted.
Undersökning för generaliteten för lämpligt motståndarantal i Magicka ur ett flowperspektiv
Detta examensarbete undersöker skillnaden i tre olika nybörjargruppers upplevda flow då de spelat Magicka (2011) med motståndarantal som den enda skiljande variabeln. Undersökningen baseras bland annat på Csikszentmihalyis (1990) flowteori och Caillois (2001) teori om att tävlande slutar vara roligt då det urartar i kaos. Syftet med examensarbetet har varit att hitta när mest flow uppstår då nybörjare på Magicka (2011) spelar mot en viss motståndartyp, samt om detta flow bryts när för många motståndare introduceras. Undersökningen har visat att nio motståndare har resulterat i betydligt mer flow än tre, medan skillnaden mellan nio motståndare och 18 har varit obetydlig. Examensarbetet har dock inte lyckats kvantifiera var flow övergår till kaos med den testgrupp och motståndartyp som använts. Framtida forskning skulle exempelvis kunna undersöka på vilket sätt ett varierande motståndarantal skulle påverka flow för en mer erfaren testgrupp som spelar mot andra motståndartyper..
Effektivisering av destruktionsprocess : En förstudie om hur Fresenius Kabi kan effektivisera befintlig destruktionsprocess
This thesis is a feasibility study into how Fresenius Kabi may rationalize their destruction process in regards to cost, recycling, and work environment. The two main objectives are to identify scrap flows and the possibility to improve or replace the equipment that is now carrying out the physical scrapping. The flow has been visualized by a flow chart of the material and communication. A chart of the problem established to visualize where improvements are necessary. Based on the problems proposals are presented on how to improve the flow thru the plant.During analyze of the physical scrapping equipment it was also necessary to take a deeper look at how they are carrying out there work today, how does the procedure look like, working environment and where are the weaknesses.
