As a result of the globalization around the world, customer demands are increasing and competitors are growing, not least in the production industry. Due to this, companies are constantly forced to improve and develop their business in forms of both production and working environment. ********** is one of the worlds largest manufacturing companies, in the field of ventilation systems. The company has today identified problems with delivery times with their product ReCooler, which is a component in their ventilation system eQ Prime. The purpose of this report has been to examine the production flow for the ReCooler and identify the potential reasons to why the lead time is so long. Once the problem areas have been identified, improvement proposals have been developed with the goal of implementing these in the production. Further, in the future being able to reduce lead times and increase delivery precision towards customers. Many literature studies were reviewed, and the method of value stream mapping was considered appropriate for the purpose of the study. The value stream mapping generated one mapping of the current flow in the production and one of the desirable future flows. Thenceforth, a gap in between was found in which the improvement potential could be seen. By examining the gap and areas of improvement, various improvement proposals were developed. The main focus in the proposals was changing one part of the production flow, and manufacture rotors towards a warehouse instead of producing them on demand. The conclusion was to implement a supermarket, a production line and Kanban-cards. These improvement proposals would be resulting in shorter delivery lead times, production lead times and better delivery precision.     Keywords: Lean production, Kaizen, Value Stream Mapping, Production Flow.

Producerande företag har utvecklats enormt de senaste decennierna. Det har gåttfrån att vara ett lokalt sågverk till att använda högteknologiska robotar.Globaliseringen har gjort att konkurrenssituationen blivit allt mer komplex ochsträng. Stora producerande företag kan verka konkurrenskraftigt globalt och dettaleder till att ännu större krav ställs på de lite mindre företagen, för att de ska hanågon chans att träda in på marknaden. Eftersom produktiviteten för producerandeföretag hela tiden ökar. För lönsamhet krävs därför ett ännu större fokus påeffektivitet och eliminering av slöserier. Därför valdes undersökningsfrågan:Hur kan produktionsprocesserna och värdeflödet ef ektiviseras på ett producerandeSME-företag?Syftet med fallstudien är att öka förståelsen för hur producerande företag kaneffektiviseras genom att bland annat kartlägga nuläget och utföra envärdeflödesanalys. Som hjälpmedel kommer olika lean-production verktyg kommatill användning för att öka effektiviteten och eliminera slöserier.För att kunna ge ett omfattande svar på undersökningsfrågan har en analysmodelllegat som grund för studien. Analysmodellen har gjort planeringen av fallstudienmer konkret. Analysmodellen består av fyra faser och den första fasen är att samlain data i olika former. Den andra fasen är att beskriva den nuvarande situationenproduktionsprocesserna har, med hjälp av den insamlade datan för att senare kunnautforma en värdeflödesanalys. Den tredje fasen är att identifiera olika typer avslöserier genom att kartlägga nuläget. Fas fyra är förbättringsförslag på hur man kaneliminera dessa slöserier och ge en mer effektiv framtida produktion. Den förstafasen har genomförts genom att samla in befintlig teori för att ha något att utgå ifrånoch jämföra med. Kartläggningen av nuläget som är väsentlig för fallstudienutformades genom observationer, tidsmätningar och intervjuer för varje enskildprocess. Den empiriska informationen jämfördes med den teoretiska insamladeteorin och olikheter dokumenterades. Detta ledde till att slöserier kunde identifierastill stor del med hjälp av olika lean verktyg. En värdeflödesanalys utfördes för attdela in den tillgängliga tiden i värdeskapande tid och icke värdeskapande tid för attkunna rangordna vilken process som är i mest behov av förbättring.Resultatet som analysmodellen har presenterat är att fallföretaget bör implementeraSMED, 5S, underhållsarbete och mer dokumentering för att ständigt kunnaförbättras. Efter att fallföretaget har implementerat dessa lean verktyg och detfungerar bra i praktiken finns det utrymme för ytterligare förbättringsmöjligheter.Bland annat genom att använda sig av ett dragande system istället för ett tryckandeoch på så sätt göra sig av med flertalet lager. Alla dessa metoder skulle leda till attfallföretaget blir mer konkurrenskraftiga.

Traditional methods of project management are not appropriate for complex projects anymore. Since projects are becoming increasingly complex and uncertain, interaction between activities and resources is growing in ways not considered by these methods. Nowadays, managers need more agile project management methods that are able to recognize and deal with uncertainty and to produce the expected results. Lean project management, the most recent approach of lean methodology, appears as an alternative approach capable of dealing with complexity and uncertainty. The latest investigations in the field show that traditional methods are still adequate for simple projects, while lean methods are more appropriate for complex projects. This thesis aims to investigate the nature of lean project management and to examine project risk management processes so that managers can assess the complexity of projects before their beginning and decide which method to apply in order to manage them.

Consequently, there are frequent proposals to streamline and enhance processes in mining operations. This study deals with ore transportation in mechanized mining units and aims to optimize fleet management using the Lean Six Sigma methodology to obtain a model in this specific process. The proposed method was implemented using a Lean Six Sigma instrument known as DMAIC (Define, Measure, Analyze, Improve, and Control). The case study was applied to an underground mine located in the Huancavelica region, Peru. The simulation showed that 24% of the time in the ore transport cycle is un-productive time and the improvement potential time represents 53% of the transportation process time.

In line with today's emergence of new technology, there is high competition within the manufacturing industry, which places higher demands on today's industries to develop new strategies to withstand the fierce competition. For this reason, today's industry needs to be more efficient and is becoming increasingly digitized, which is the core of the new industrial revolution called "industry 4.0".  The aim of this study is to investigate, with the help of value flow analysis, new innovative tools, and principles within lean production, whether the manufacturing process can be more efficient. The study was carried out at a manufacturing company that produces dehumidifiers and has ambitions to streamline it’s manufacturing process.  Through the literature review, site observations, interviews and data analysis, a comparison was made with the theory to find solutions to the problems that emerged. The results of this study show that it is theoretically possible to make a manufacturing process more efficient using these methods. It can be pointed out that one important study will be to test these solutions to see what results can be achieved. / I linje med dagens framväxt av ny teknik råder det hög konkurrens inom tillverkningsindustrin, vilket ställer högre krav på dagens industrier att utveckla nya strategier för att stå emot den hårda konkurrensen. Av den anledningen måste dagens industri bli mer effektiv och digitaliseras alltmer, vilket är kärnan i den nya industriella revolutionen som kallas "industri 4.0".  Syftet med denna studie är att med hjälp av värdeflödesanalys, nya innovativa verktyg och principer inom lean production undersöka om tillverkningsprocessen kan bli mer effektiv. Studien genomfördes på ett tillverkningsföretag som producerar avfuktare och som har ambitioner att effektivisera sin tillverkningsprocess.  Genom litteraturgenomgång, platsobservationer, intervjuer och dataanalys gjordes en jämförelse med teorin för att hitta lösningar på de problem som uppstod. Resultaten av denna studie visar att det är teoretiskt möjligt att effektivisera en tillverkningsprocess med hjälp av dessa metoder. Det kan påpekas att en viktig studie kommer att vara att testa dessa lösningar för att se vilka resultat som kan uppnås.
