Efficient use of resources and utility is the key to reduce the price of the commodities produced in any industry. This in turn would lead to reduced price of the commodity which is the key to success. Sustainability involves integration of all the three dimensions: environmental, economic and social. Sustainable manufacturing involves the use of sustainable processes and systems to produce better sustainable products. These products will be more attractive, and the industry will know more about the climate impact from their production. Manufacturing companies use a considerable amount of energy in their production processes. One important area to understand the sustainability level at these types of industries is to study this energy use. The present work studies energy use in a large-scale tool manufacturing company in Sweden. Value Stream Mapping method is implemented for the purpose of mapping the energy use in the different operations. To complement this, an energy audit has been conducted, which is a method that include a study and analysis of a facility, indicating possible areas of improvements by reducing energy use and saving energy costs. This presents an opportunity for the company to implement energy efficiency measures, thus generating positive impacts through budget savings. Less energy use is also good for the environment resulting in less greenhouse gas emissions level. This also helps in long-term strategic planning and initiatives to assess the required needs and stabilize energy use for the long run. Social sustainability completes the triad along with environmental and economic sustainability. In this study, the social sustainability is reflected with the company’s relationship with its working professionals by conducting a survey. The sustainable manufacturing potential found in the case study indicates that significant progress can be made in the three sustainability dimensions. Although, the scope of the thesis is limited to a tool manufacturing company, several of the findings could be implemented in other tool companies as well as industries belonging to other sectors. / <p>The thesis is a joint report between Linköping and Uppsala University.

I dagens samhälle finns ett stort behov av processeffektiviserings-metoder för att hålla företaget konkurrenskraftigt gällande produktivitet och effektivitet. Samtidigt satsar företag idag mycket på ekologisk hållbarhet, vilket har öppnat dörren för nya så kallade Green Lean-metoder vars syfte är att förbättra både produktivitet och hållbarhet. I detta arbete behandlas metoderna 5S, Environmental Value Stream Mapping, Green Lean Six Sigma samt Green Kaizen. Syftet med arbetet var att redogöra för innebörden av respektive metod samt motivera hur dessa metoder bör appliceras och implementeras i praktiken. Först behandlades metoderna teoretiskt, därefter praktiskt med enkäter. I arbetet behandlar vi företaget Scania och undersöker hur de valt att applicera och använda de metoder, hållbara metoder, de idag använder. Resultatet visade att det finns flera olika drivkrafter till varför man väljer att implementera Green Lean-metoder samt flera olika aspekter som påverkar vilka metoder som bör väljas, som exempelvis kundkrav eller erfarenhet och kunskap inom företaget. Scania använder idag Green Performance Map och Energy Kaizen som Green Lean-metoder. Slutsatsen som drogs är att metoden som bör implementeras varierar beroende på vad företaget tillverkar, hur långt de kommit med andra processeffektiviserings-metoder såsom Lean Production och Six Sigma. Om det är en problemdriven lösning så är EVSM en stark metod medan 5S bör implementeras uppifrån ledningen. / In today's society, there is a significant need for process improvement methods to maintain a company's competitiveness regarding productivity and reasonable pricing. Additionally, companies are investing heavily in environmental sustainability, leading to the emergence of new "Green Lean" methods aimed at creating improvements in both productivity and sustainability. This study examines the methods of 5S, Environmental Value Stream Mapping, Green Lean Six Sigma, and Green Kaizen. The aim of the study is to explain the meaning of each method and to motivate how these methods should be applied and implemented in practice. The methods were first studied theoretically and then practically with surveys. Scania was chosen as a case study to examine how they have chosen to apply and use the methods they have. The results showed that there are several driving forces for why companies choose to implement Green Lean methods, and several aspects affect which methods should be chosen, such as customer requirements or experience and knowledge within the company. Scania currently uses Green Performance Map and Energy Kaizen as Green Lean methods. The conclusion drawn is that the method to be implemented varies depending on what the company produces, and how far they have progressed with other process improvement methods such as Lean Production and Six Sigma. If it is a problem-driven solution, EVSM is a robust method, while 5S should be implemented by top management.

Increasing global competition, high stumpage and energy prices, and the slowing housing market have challenged the U.S. hardwood lumber industry during the past several years. Many wood product manufactures are trying to remain in business by implementing continuous improvement programs like lean manufacturing. However, the lumber drying process where lumber is kiln-dried in large batches, can significantly increase manufacturing and inventory lead-time; and is a process that tends to limit how lean the remaining process can become. Vacuum drying has the potential to reduce drying times, reduce batch sizes and achieve product quality comparable or superior to conventional drying. The overall goal of this research was to evaluate how vacuum-drying technology could support further lean implementation in manufacturing of hardwood products. Specifically, to estimate conventional and vacuum drying times, quality, and costs for drying 4/4 red oak lumber; to determine by the use of feasibility analysis (cash flow, net present value, and internal rate of return) differences between conventional and vacuum drying for 4/4 red oak lumber; and to determine if the high capital cost of vacuum drying equipment can be justified with the reduction of WIP and cycle time, while meeting desired throughput. The study includes a cost analysis of vacuum and conventional drying, and a determination of the potential financial gains associated with the reduced drying times via vacuum drying. It was determined that vacuum drying quality was equal or better than conventional drying with less checking, end splits, drying stress and shrinkage. Compared to conventional drying, vacuum drying times with air drying and without air drying were 67% less and 70% less, respectively. Conventional and vacuum with no air drying scenarios were determined to be financially feasible when compared using Net Present Value and Internal Rate of Return analysis. However, vacuum drying with no air drying had better NPV and IRR values than conventional drying. The scenario of vacuum with air drying was not feasible. Two case studies, each employing the three drying scenarios (conventional drying, vacuum with air drying, and vacuum without air drying), were used to determine the impact of cycle times and work in process. It was determined that the cycle times for vacuum drying were 87% and 95% less than conventional drying for the first case study and 51% and 90% less than conventional drying for the second. WIP was 48% and 84% less in the first case study and 43% and 92% less than conventional drying for the second. Cycle time was reduced by 87% and 51% for Plant C and D, respectively. Finally it was determined that the reduction of WIP represented a cost saving of 73% and 76% for the two case studies. The reduction in costs, faster drying rates, and equal quality, and reduced cycle times make vacuum drying a potential technology available for improvement of the competitiveness for flooring manufacturers. / Master of Science

Yes / Operations management theory suggests that professional services firms (PSFs) have some distinct operational challenges. The purpose of this paper is to trace the emergence of professional service operations management (PSOM) thinking within a legal partnership. With the impact of deregulation there is an emerging consensus that legal services is changing, due to the socio-economic and political climates in which they operate. The purpose of this paper is to trace the value-add through the legal profession and examine how PSOM practice can be applied within a legal practice in order to create a leaner thinking. The case study analysis suggests a potential methodological mismatch between the core theoretical frameworks, exploring features of effectiveness and efficiency across legal disciplines. This paper makes a contribution through a reflection of PSOM thinking in law.

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines. / Denna rapport är resultatet av ett examensarbete utfört på Risifruttiproduktionen hos företaget Procordia Food AB. Examensarbetet är på D-nivå och är det slutgiltiga arbetet för att författaren ska få en Civilingenjörsexamen inom Innovativ produktion vid Mälardalens Högskola. Examensarbetet omfattar 30 högskolepoäng och har pågått i 18 veckor.   Examensarbetet är i huvudsak en forskning av huruvida det är möjligt att utföra en Miljövärdeflödesanalys på en livsmedelsprocessindustri samt en utvärdering av om Miljövärdeflödesanalys och Green Performance Map verktygen är användbara i denna typ av industri. En bidel till denna forskning är att med hjälp av resultaten från Miljövärdeflödesanalysen ge Procordia Food AB information om vad som bör förbättras i Risifruttiproduktionen.   Författaren har haft det svårt att samla in vissa kvantitativa data till Miljövärdeflödesanalysen, främst beträffande energiåtgång i delprocesserna, men har ändå med hjälp av en Värdeflödesanalys och andra Lean verktyg kunnat identifiera och kvantifiera flera slöserier i Risifruttiproduktionen. Rekommendationer till förbättringar baserade på dessa slöserier har givits till företaget.   I forskningsanalysen har verktygen Värdeflödesanalys, Miljövärdeflödesanalys samt Green Performance Map användbarhet i en livsmedelsprocessindustri analyserats. Författaren har funnit att Värdeflödesanalys är ett användbart verktyg då slöserier och ojämnheter i produktionstakt har kunnat identifieras. Miljövärdeflödesanalys och Green Performance Map verktygen är också bra verktyg när ett företag vill analysera sin miljöbelastning för att sedan investera i miljöförbättringar. Dock har inga djupare energianalyser kunnat göras i Risifruttiproduktionen eftersom energimätare för el, ånga och tryckluft saknades i produktionen.

This study contains suggestions for the question “How might the future production setup at Permobil look like?”. The idea is to provide solutions based on inputs from the current knowledge boundariesand practices of the production team. The work aims at gathering data from the current practices within the firm, identify the wastes, needs, and potential improvements and conducting studies on state-ofthe-art Industrial practices, trends, and upcoming future technologies in production. Value stream mapping is done to help better understand the current state across the production facility and hence plan for future production setup. The solutions on strategies for key areas, namely, warehousing, production line, material handling, quality control and overall integrated production setup are derived from first benchmarking against Industrial practices and then deriving options for the flow of resourcesand information across the Production value chain. The study suggests in-detail ideas of what all production trends can be incorporated for the new upcoming production setup in the future and is in tight accordance with Permobil’s lean principles.With the findings from Value Stream Mapping, we made suggestions for new layouts for the newfactory, and we ranked these suggestions based on an evaluation model. Automation in material handling, setup of the assembly line, changes in current customization setup and use of technology in many ways to aid in the operations are identified as the important transitions for future setup. Finally using the results from the layout suggestions, we performed a warehouse simulation between the suggested layout and the current layout based on distance travelled and parts delivered to line.Concluding this study by connecting the findings from VSM, Layout suggestions and Warehousesimulation. / Denna studie innehåller förslag på frågan ”Hur kan den framtida produktionsupplägget hos Permobilse ut?”. Tanken är att tillhandahålla lösningar baserade på input från produktionsteamets nuvarande kunskapsgränser och praxis. Arbetet syftar till att samla in data från nuvarande praxis inom företaget, identifiera avfall, behov och potentiella förbättringar och genomföra studier om toppmoderna industriella tekniker, trender och kommande framtida teknologier i produktionen. Värdeströmskartläggning görs för att bättre förstå det nuvarande tillståndet i produktionsanläggningenoch därmed planera för framtida produktionsupplägg. Lösningarna för strategier för kritiska områden, nämligen lagerhållning, produktionslinje, materialhantering, kvalitetskontroll och övergripande integrerad produktionsuppsättning härrör från först benchmarking mot industriell praxis och sedan härledande av alternativ för flödet av resurser och information över hela produktionsvärdekedjan. Studien föreslår detaljerade idéer om vad alla produktionstrender kan införlivas för den nya kommande produktionsuppsättningen i framtiden och är i strikt överensstämmelse med Permobils lean-principer. Med resultaten från Value Stream Mapping gav vi förslag på nya layouter för den nya fabriken, och vi rangordnade dessa förslag utifrån en utvärderingsmodell. Automatisering i materialhantering,uppsättning av löpande band, förändringar i nuvarande anpassningsupplägg och användning av teknik på många sätt för att underlätta verksamheten identifieras som viktiga övergångar för framtidainstallationer. Slutligen med hjälp av resultaten från layoutförslagen genomförde vi en lagersimulering mellan den föreslagna layouten och den aktuella layouten baserat på tillryggalagd sträcka och delar levererade till linjen. Avsluta denna studie genom att koppla samman resultaten från VSM, layoutförslag och lagersimulering.
