When an error occurs in an IT system that is vital for the production of a major industry, the consequences can be great. To quickly identify and correct errors is important as a stop in a system can lead to a break in production, which is costly for the industry. Our task in this thesis has been to develop a system for ÅF that facilitates the debugging process of the system Paperline. The system's target audience is ÅF-call personnel that provides support for Paperline 24 hours a day if something goes wrong. The system consists of a Windows service, a database and a web application and is developed mainly with the techniques C#.NET, MVC 5, Google Charts, Javascript, HTML, CSS, and Entity Framework.

Förändringsarbete är av en komplex karaktär, men en förutsättning för att företag ska kunna behålla sin konkurrenskraft. Det finns en mängd olika förändringsmetoder vars syfte är att effektivisera verksamheten. En av dessa förändringsmetoder är Lean som har sina rötter inom Toyota och dess produktionsmetod TPS (Toyota Production System). Lean syftar till att eliminera alla former av slöseri och därmed effektivisera en verksamhet. Studier visar på att företag i västvärlden har lätt att applicera verktygen och arbetsmetoderna inom Lean, men har svårt att ta till sig hela filosofin som ska genomsyra organisationen och dess kultur.Syftet med denna studie är att undersöka vilka de kritiska faktorerna vid en Lean-implementering är och hur dessa hanteras.

Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

De tankar om förbättringsprocesser som tillslut har blivit konceptet Lean härstammar ifrån ?The Toyota Production System? där Kiiro Toyodas vision att alla delar av en bil skall levereras precis ?i rätt tid? står i fokus. Delarna som arbetarna behöver skall alltså vara tillgängliga precis när de behöver dem varken förr eller senare. Det tog tid innan hans vision blev realitet men ett decennium efter hans död använder hela Toyota koncernen sig utav hans idéer över hela världen. Man kan se systemutveckling som en form av produktutveckling.

In this thesis an energy analysis of ethanol production at the ethanol plant of Lantmännen Agroetanol in Norrköping has been performed. The ethanol plant has been studied in combination with Händelöverket, the combined heat and power plant which provides the ethanol process with steam. The purpose of this study was to determine the energy consumption for the whole production chain from grain to ethanol. The analysis has included the energy consumption for cultivation of grain, production of chemicals, the production chain for wood chips, the steam production and the ethanol plant. The grain and wood chips are both considered raw materials there for the energy content in these are not included as energy input in the system.

Titel: PMC WAY ? Vägen till effektiv produktionProblem: Hur kan PMC AB använda sig av Lean production-konceptet för att få en mer produktiv och effektiv produktion?Syfte: Syftet med denna uppsats är att på uppdrag av PMC AB genomföra en studie om konceptet Lean production, för att sedan ta reda på hur PMC AB kan använda sig av detta koncept i sin produktion för att bli mer effektiva och produktiva.Metod: För att genomföra studien har primär- och sekundär data använts. Den primära datan har samlats in genom intervjuer med personer på PMC AB samt observationer i produktionen. Den sekundära datan består av information insamlad från litteratur, artiklar, Internet och broschyrer.Resultat: Studien visar att Lean production inte bara är användbart i stora österländska företag såsom Toyota, utan går att implementera på alla olika sorters företag. Konceptet betonar dock vikten av att grundligt gå igenom alla delar av företaget och inte glömma någon.

This report is the result of a master thesis at Linköping University - Institute of Technology and Uppsala University at the request of the chassi workshop at Scania CV AB in Södertälje. Since the beginning of the 90's, Scania CV AB has had a close cooperation with Toyota from which, among other things, the Scania Production System (SPS) has evolved. SPS explains Scanias' values, principles and priorities. The Technician department (MST) at Scania Chassi in Södertälje believes that SPS can streamline the technicians work and help them become a more homogeneous group. The purpose of this master thesis is to initiate an implementation of SPS within MST through two pilot projects involving both the product and process technicians. The SPS principle Normal Situation - Standardised working method was required to be implemented within one work task each for the two groups of technicians with special attention on the three subprinciples Standardisation, Takt and Balanced flow. The master thesis fulfilled its purpose as the two pilot projects initiated the implementation of SPS within MST and the three sub-principles Standardisation, Takt and Balanced flow were implemented within the two chosen work tasks.

The avowed aim in this project was to see how the Swedish egg production is today. My first question was if the Swedish egg producers egg production turn a profit. I have done five after calculation at five different egg producers with different systems from case to case. The difference has been the living system, the fodder and the egg price. They made a report in Uppsala, Sweden (Hoffman & Andersson, 1996), where the look forward to a Swedish cage ban and made calculations after that coming ban. After that they lift the Swedish ban of cages and the egg producers could invest in new cages who called the decorated cage.

Lantmäteriets stödenhet Utveckling och IT (UIT) ska inför ett mer agilt arbetssätt. Den agila arbetsmetoden ifråga är Lean Thinking, den västerländska adaptionen av Toyota Production System. För att underlätta vid en övergång till det nya arbetssättet, kartläggs de inledande faserna i projektarbetet, då dessa saknar specifika anvisningar i den nuvarande projektstyrningsmodellen, Praktisk projektstyrning (PPS). Utifrån kartläggningen utfördes så en tvåstegsanalys, den första utifrån ett distribuerat kognitivt perspektiv och sedan utifrån de fem huvudprinciper från Lean Thinking. Resultatet från analysen resulterade sedan i ett antal förändringspunkter som UIT kan använda sig av vid bytet av arbetssätt.

Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output. <br/><br/>Purpose: The purpose of this master thesis is twofold, (1) to examine applicability of complexity theory through agent-based modelling on a production process (2) to identify improvement areas in order to increase the production output at SKS production site in Eslöv, by modelling and simulating the production process through an agent-based model. <br/><br/>Method: The chosen method of this study is a combination of a case study and a complex system approach. The empirical data was collected through interviews, observation and document studies which were analysed through an agent-based simulation model.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

To value the risk and opportunity for our production in Sweden it is necessary to understand the marketing development for beef cattle production in the world. We have chosen to look at the Brazil beef cattle production. They are one of the biggest producers, have good opportunity to develop further and have a big affect at the world market. The method of our work is to gather information from experts of beef cattle production, located in Brazil. We have also gathered information through studies of literature. The factors that will have a big influence at the Brazil beef cattle production during the upcoming years is more efficient land use, lower age of slaughtering and extended use of feedlot-system. Our conclusion is that the Brazil beef cattle will have a sharp increase during the next five years. The amount of pasture will not change during that time.
