This diploma thesis is focused on examining the activities of production planning and examining the efficiency of the selected machine in the selected company. The theoretical part summarizes the most important findings and methods of lean manufacturing and corrective measures to prevent or eliminate downtime. In the analytical part, the selected machine is examined in terms of the production process, then an analysis of the current state and assessment of the collected data is performed. Furthermore, an analysis of the decision-making process in production planning for a selected machine was performed and shortcomings in planning were assessed. The practical part contains suggestions for removing the identified bottlenecks.

I dagens arbetsklimat uppstår hela tiden olika utmaningar för tillverkande företag och organisationer. Ökad konkurrens, utvecklingar av olika tillverknings- och informationstekniker samt alltmer krävande kunder är några av utmaningarna. Ett sätt att lyckas maximera kundvärde samtidigt som den interna produktiviteten och effektiviteten ökar är att implementera konceptet Lean, vilket kort kan sammanfattas som att göra mer med mindre.  Ackert Reklam är ett litet familjeägt aktiebolag som grundades 1982. Företaget producerar dekormaterial i olika former, allt från enklare kampanjdekorer till mer avancerade reflexdekorer. Ackerts filosofi är att på ett så kostnadseffektivt sätt som möjligt lyckas lösa kundernas behov av högklassig visuell kommunikation. I dagsläget har företaget problem i form av bristande standardisering av deras arbetssätt och letar därför efter lösningar inom Lean.  Syftet med den här studien var att hjälpa företaget att standardisera sina arbetssätt och finna rutiner med hjälp av en implementering av olika värderingar, principer och verktyg inom Lean. För att lyckas uppnå syftet togs två mål med studien fram: -          Identifiera befintliga värderingar, principer och verktyg inom Lean som går att anpassa på mindre tillverkande företaget.  -          Ta fram en implementationsmetod av Lean, i form av ett ramverk, som går att applicera på mindre tillverkande företag.   Studien genomfördes i form av en kvalitativ fallstudie där datainsamlingen utfördes med hjälp av intervjuer och observationer. Totalt utfördes en ostrukturerad intervju och sju semi-strukturerade intervjuer. Observationerna gjordes genom att fysiskt befinna sig på arbetsplatsen och studera arbetsprocessen.  Med hjälp av datainsamlingen i form av intervjuer och observationer samt av teori i form av olika värderingar, principer och verktyg inom Lean kunde en slutsats och rekommendationer tas fram. Studien visar att en implementation av Lean kan hjälpa Ackert att standardisera sina arbetssätt om den sker på rätt sätt och olika kritiska faktorer tas i beaktning. Företaget rekommenderas att följa det framtagna ramverket där initialt fokus ska ligga på att skapa en god intern kommunikation samt att träna och utbilda anställda inom Lean.

The thesis focuses on the study of the effectiveness of the production line in selected company. The aim of this work is to find bottlenecks in production and provide solutions to find time savings. The production line was analysed in terms of time efficiency and the results of the analysis are countermeasures to increase time efficiency of the production line.

The diploma thesis deals with the problematics of lean production in a selected company. The analytical part includes the introduction of the company and the analysis of the current state with using lean manufacturing tools to optimize material flows. The thesis is divided into four parts. The first part describes the objectives and methodology, followed by the theoretical basis of the work and analysis of the current state of the company. The final part includes suggestions of possible solutions leading to elimination or improvement of identified problems.

This thesis deals with the design of a lean manufacturing process with the main focus on the modification of the production layout of the heat pump production line, at Daikin Device Czech Republic s.r.o. In the introductory part of the thesis, the theoretical background is elaborated and then the company is introduced briefly. The next part analyzes the currently produced models, production processes, the line in terms of current layout and finally the process times. Based on these analyzes, a new layout of the production line and storage space is presented. In the next part of the thesis, the conditions of implementation are defined. The final part evaluates the benefits of this work based on the real results that the new layout resulted in.

The master thesis concerns a project to streamline the production process by designing an assembly line to produce glass doors. The aim of the project is to increase the productivity due to the increasing demand of customers for products. The production process is analysed by mapping the value stream and finding a suitable solution using industrial engineering and lean manufacturing methods. In order to ensure successful project implementation project management tools and methods are used. The project also includes economic evaluation of the investment.

The work is focused on improving the concept of lean management in a selected engineering company, where analyzes are performed with the help of selected methods and tools to reveal current problems. The data are then processed and based on them, measures for change are proposed with an emphasis on minimizing the rate of waste of time and costs and increasing production efficiency.

The Master’s thesis deals with the approaches to the introduction of the principles of lean manufacturing and especially the concept of Just in Time (JIT). It is structurally divided into theoretical and practical part. While the theoretical part focuses on the theory of lean manufacturing and the details about steam turbines, the practical part gradually deals with the introduction of the company, production portfolio, supplier analysis and especially the production process. The practical part ends with the selection of proposals for changes in the production concept, including partial economic evaluations with regard to customer requirements to meet delivery dates, quality and required costs.

This thesis assesses the potential of using computer simulation to aid existing lean manufacturing training methods such as lecture and live simulation. An investigation of this possibility was carried out in conjunction with UMEP's Lean 101 class. In the study, two experimental computer simulation models demonstrating the push and pull production scenarios were constructed using ProModel software. Simulation models were equipped with a Visual Basic interface to aid trainees to manipulate the model via ActiveX. Constructed computer simulation was compared with live simulation to answer these research questions: 1. Was computer simulation able to teach additional lean concepts not covered in live simulations? 2. Was training time less for trainees going through a computer simulation than for those going through a live simulation? 3. Was a computer simulation quicker and easier to set up than a live simulation for trainers? 4. Did computer simulation achieve comparable educational objectives as live simulation? Objective measurements for first three questions were positive and conclusive. For the fourth one, a survey was conducted among trainees of a treatment group (computer simulation only) and a control group (live simulation only) to collect responses. Statistical analysis of the subjective responses indicated the computer simulation aided the trainees to learn and implement lean manufacturing, but was not as effective as live simulation. Holistically, these results did not warrant the complete changeover from live simulation to computer simulation. Yet, a combined implementation of computer simulation and live simulation was proposed to reap the benefits from the best of both approaches.
