(the TCI) and suggestions for improvement measures. The first chapter presents theoretical basis for processing work. PMT methods, namely MTM and MOST, lean production with a focus on 5S, TPM and Kaizen are described. The second chapter is focused on the company TCI, core business, organization structure and analyzes the current status. It’s focused primarily on the process of critical non-manufacturing operations and the changeover cleaning process. The third chapter, following the analytical part consists of the proposed recommendations. The fourth chapter deals with the final evaluation.

The construction sector in Sweden released 21% of the country’s CO2-e emissions in. With aggressive climate and pollution goals these emissions cannot be allowed to increase. There is therefore a need for more efficient construction methods and techniques in the Swedish construction sector. The construction sector is today split up between industrial construction and traditional construction. Industrial construction handles the construction process with a strong emphasis on the process and allocates all its efforts toward streamlining the process and removing wasteful steps and elements. Traditional construction places more focus on the individual project. It has one major advantage, which is its exceptional ability to adapt the specific project according to the wishes and demands of the customer and the project’s other unique circumstances.   The IHB-model is the theory of industrial construction used in this study. This study seeks to find out which parts or mindsets from the IHB-model that can be applied to a traditional construction company, OF Bygg in Umeå, to increase its efficiency. This is done by studying the current use of industrial methods by OF Bygg, their views of industrial construction and comparing this to the IHB-model and looking at what parts can be applied to OF Bygg without fundamental shakeups in the company’s structure. The study of OF Bygg is mainly done through interviews with respondents from the company.    During the interviews, a sense of general positivity towards industrial construction was given off by the respondents. It also became apparent that OF Bygg was partially industrialised in some areas, but that there remains big possibilities for improvement.   Off-site manufacturing is used today in the shape of “field factories” and supply deals with industrial suppliers. Both of these are great industrialised methods and should be expanded upon whenever possible. Developed technical systems are used in most projects during certain stages. Efforts should be put into using these more extensively. ICT-tools are also used in most of OF Bygg’s areas but vertically integrating these tools further should be explored. Long term relations between OF Bygg and other market participants are rare since they’re considered detrimental to the health of the local market. Supply chain management is being handled through deals with logistics companies. OF Bygg could become their own logistics company with a centralised material warehouse to ease the logistics and enable use of JIT. Planning and control of the process is mostly handled through general project schedules. The Last Planner system alongside stricter routines is suggested. Customer focus is currently unnecessary for OF Bygg to bother with due to restrictions in the local market. Performance measurement and re-use of experience often get under prioritized often due to lack of time. The transfer of responsibility from the project or site management to a role specified to handle performance measurement and re-use of experience is encouraged.

This dissertation is focused on a research of using methods of Lean Production in working environment of selected companies in the Czech Republic. In the introduction the author mentioned theoretic facts about Lean Production, which is originally from Japan. The rest of dissertation also included characteristics of selected companies and description of situations in companies before and after using Lean Production methods. At the end of each part we can find conclusion and suggestion of specific new steps for these companies. A company, called Linde Pohony s.r.o. Český Krumlov, have been using these methods: TPM, 5S and visual management. In a company Rohde & Schwarz, which is located in Vimperk, have been using the methods of Lean Production. : Kanban and also visual management. And a company ČSAT a.s. Praha have been testing methods of Lean Production: MUDA, 5S, Kaizen with a diagram of Ishikawa. In conclusion of the dissertation assumptions were evaluated. The overall summary of exercising Lean Production in companies - Linde Pohony s.r.o. Český Krumlov, ČSAT a.s. Praha a Rhode & Schwarz - Vimperk, were mentioned as well. Outcomes of the dissertation can be used for companies, which had been analyzing or for other companies with similar specializations. The dissertation provides the analysis of utilization selected Japanese principles of Lean Production in Czech companies.

The purpose of this thesis is to implement Total Productive Maintenance (TPM) in Nigeria Plastics Manufacturing Company. Manufacturing companies round the world pay huge amount of money for purchasing new equipments to boost their production however nothing or little is done to achieve or obtain full output from the machine for which it is intended to do. Small losses in time or deviations from planned or calculated capability are taken as usual machine performance. But currently as a result of improved capability levels and demand of quality product at lower prices, purchasing latest machine/equipment is not a way out unless it is completely used. Total Productive Maintenance (TPM) is a method that involve everybody totally, from high management to all workers to implement a complete maintenance program for all machine/equipment during its life. This method ends up in most effectiveness of tools, equipment, virtuously improved workers, tidy up working area, neat and clean working environment. A structure is going to be developed with the potential of evaluating the impact of implementing total productive maintenance within. By evaluating the result or outcome of Total Productive Maintenance (TPM), manufacturing companies can create sensible/smart decisions to improve the potency and standard of the machine, equipment and also the product on XYZ Plastics Manufacturing Company in Nigerian.

The topic of this thesis project is multimedia processing, focusing on the user-sided adjustment of RGB values in video streaming using Just-In-Time (JIT) techniques and the Media Lovin’ Toolkit (MLT) framework. This is implemented in Codemill’s Accurate Player and using Web Real-Time Communication (WebRTC) as a data channel. Colour theory and RGB colour representation are discussed and technical details on the structure and usage of the MLT framework are provided. The first part of the research question aims to evaluate the feasibility of the real-time colour adjustment. This research question is answered positively by providing an implementation that can address real-world use cases. A comparison of different MLT filters is included, to select the most suitable filter for the RGB adjustment. The second part of the research question considers the comparison of video colour grading results with MLT filters that were applied on different platforms: The Accurate Player, the command line video editor Melt and the editing software KDEN Live. For this, frames of the different platforms were extracted and subtracted from each other to show differences in the colour saturations. The results reveal that the Accurate Player plays back the original video more accurately than the Melt framework. Additionally, the results lead to the assumption that KDEN Live is not using the same Melt filter as the Accurate Player to adjust the RGB values. Those significant differences in the compared frames show the complexity of the topic of colour adjustment and representation.

<p>Denna rapport är resultatet av ett examensarbete utfört vid Institutionen för industriell och ekonomisk utveckling vid Linköpings universitet på uppdrag av konsultbolaget Sustainia AB. Lean produktion, ofta benämnt Lean, har det senaste decenniet blivit en allt mer attraktiv produktionsfilosofi för att minska kostnader och öka kundnöjdhet genom förbättrad leveransservice och effektivare flöde. Ett flertal författare har påpekat att införandet av Lean direkt kan förbättra ett företags miljöprestanda, främst till följd av det minskade slöseri som Lean avser ge upphov till. Vidare finns studier som visar att vissa möjligheter till förbättringar och kostnadsbesparingar riskerar att gå oupptäckta om verksamheten ses ur ett strikt Lean-perspektiv. Med ett miljösynsätt finns dock chans att dessa blir upptäckta. Detta indikerar att såväl kostnads- som miljömässiga fördelar kan nås genom en integration av arbetet med Lean och miljöaspekter.</p><p>Syftet med detta examensarbete har varit att undersöka hur ett företags arbete med Lean respektive miljöaspekter påverkar varandra för att ta reda på om och hur väl de båda arbetssätten skulle kunna fungera tillsammans. Om det visade sig att en integration av Lean och miljö vore möjlig och fördelaktig ur affärsmässig synvinkel skulle sedermera ett förslag tas fram på hur en sådan modell skulle kunna se ut. Arbetets syfte har uppfyllts genom en kombination av litteraturstudier och intervjuer. Fyra svenska företag som arbetar enligt Lean och även har ett uttalat aktivt miljöarbete intervjuades gällande sitt sätt att arbeta med Lean och miljöfrågor samt hur de såg på en eventuell integration av de två arbetssätten.</p><p>Utifrån resultaten från litteratur- och intervjustudien kan konstateras att flera av grundtankarna inom såväl Lean som miljöarbete stöder varandra. Inom båda arbetssätten ses kontinuerliga förbättringar och eliminering av slöseri som viktiga inslag, och båda främjar en organisationskultur där personalen uppmuntras att lösa problem och förbättra företagets prestation. Vissa enskilda verktyg inom Lean riskerar emellertid att ha en negativ inverkan på företagets miljöprestanda, något som i många fall dock kan avhjälpas genom god planering.</p><p>Till ett företags miljöarbete kan Lean bidra med ett proaktivt förhållningssätt och strukturerat arbetssätt och därmed få organisationen att arbeta mer förebyggande och långsiktigt med miljöfrågor. De intervjuade företagen ansåg att Lean generellt hade en positiv inverkan på deras miljöarbete, även om de inte hade gjort någon utvärdering av hur arbetet med Lean påverkat deras miljönyckeltal. De kvantitativa data som erhölls från litteraturstudien pekade på att arbete med Lean kan leda till en direkt minskning av företagets miljöpåverkan inom flera områden. Med utgångspunkt i dessa kvantitativa och kvalitativa data anser författarna således att det finns starka och tydliga tecken som visar på att Lean kan ha en positiv inverkan på miljörelaterade nyckeltal. Ett aktivt miljöarbete kan å sin sida bidra till arbetet med Lean genom att besparingsmöjligheter, som annars skulle riskerat att förbli oupptäckta, uppdagas.</p><p>Studien visade vidare att det inte bara är möjligt att integrera arbete med Lean och miljö, utan att en sådan integration dessutom har potential att vara fördelaktigt ur såväl ett ekonomiskt som ett miljömässigt perspektiv. En integrering kan minska risken för suboptimeringar, och synergieffekter kan erhållas som innebär att större framgångar kan uppnås än vad som skulle ha varit möjligt om arbetet med Lean och miljö hade bedrivits isolerat. Med vetskapen om att en integration är möjlig och har potential att vara fördelaktig ur företagsekonomisk och miljömässig synvinkel utarbetade författarna en modell för hur Lean och miljöarbete kan bedrivas integrerat. I samråd med Sustainia AB bestämdes att denna modell skulle kallas Green Lean, vilket således åsyftar en miljöanpassad, ”grön” form av Lean.</p> / <p>This report is the result of a master thesis written at the Department of Management and Engineering at Linköping University commissioned by the consultancy firm Sustainia AB.</p><p>Lean production, also known as Lean, has during the last decade increasingly become a more attractive production philosophy for decreasing costs and increasing customer satisfaction by improving customer service and obtaining more efficient production flows. Several authors have pointed out that Lean has the potential to directly improve the environmental performance of a company, mostly by decreasing waste generation. Further, there are studies showing that some possibilities for improvement and cost savings risk not being discovered if the operations are seen strictly from a Lean perspective. When an environmental perspective is included there is a chance that these improvements and cost savings are discovered. This indicates that both environmental and cost related advantages might be achieved by integrating the Lean approach with that of the environment.</p><p>The purpose of this master thesis was to investigate how the work with Lean and environmental aspects affect one another. If applying the two principles together was shown to be both possible and beneficial from a business point of view, the authors would propose how these two concepts could be integrated into a single model. A combination of literature studies and interviews were used to fulfill the purpose. Four Swedish enterprises, which work according to the Lean principles and also have an active environmental profile, were interviewed about their way of working with the two approaches, as well their views on an integration of these.</p><p>From the findings in this study the authors concluded that several of the fundamental concepts concerning Lean and environmental aspects support each other. Within both, continuous improvements and waste elimination are seen as important components, and they both support an organisational culture where the personnel are encouraged to solve problems and improve the performance of the company. Conversely the authors found that there is a risk that certain of the Lean tools risk having a negative influence on the company’s environmental performance. However, in many cases this can be avoided by proactive planning.</p><p>Lean can contribute to a company’s environmental work by its proactive approach, structured way of operating and long-term way of thinking. In general the interviewed companies regarded Lean as having a positive influence on their environmental work, even though none of them had carried out an evaluation on how their work with Lean affected their environmental key performance indicators. The quantitative data obtained from the literature study indicates that Lean can lead to a direct decrease of a company’s environmental impact within several areas. As a result of these qualitative and quantitative data the authors of this thesis have found clear indications showing that Lean might have a positive impact on environmental key performance indicators. An active environmental work can also contribute to the work with Lean. Potential cost saving, which might not have been discovered with the Lean perspective, can be revealed when the organisation is studied from an environmental point of view.</p><p>The study further showed that it not only is possible to integrate Lean and environmental work, but that it also has potential to be beneficial from both a business and an environmental standpoint. An integration of Lean and environmental issues can reduce the risk of sub optimisations, and synergies can be achieved, meaning that the two systems can accomplish more together than they would in isolation. With this knowledge, the authors composed a model for how Lean and environmental work can be practised and integrated. In consultation with Sustainia AB it was decided that this model should be called Green Lean, which hence refers to an environmentally favourable, “green”, version of Lean.</p>
