Background It has become increasingly a problem that fashion products reach their end-of-life when they are still usable. Today, a fast-changing wardrobe has gained importance which is directly linked to overloaded landfills of textile waste and scarcity of natural resources. The pressure on companies to act upon this unsustainable consumption pattern is increasing. Different strategies are currently in the development. Within reverse supply chains, products are collected from the original user for value recovery. This study focuses is in particular on the reuse of clothing without additional treatments. Purpose The aim of this study is to investigate the value stream of a traditional fashion retailer entering the second-hand business. At the same time, possible challenges and potential areas of improvement should be identified. The reuse of garments should provide consumers a more sustainable alternative for consumption. To serve this purpose, a case study was conducted to describe key activities and formulate suggestions. Methodology The research was conducted as a qualitative case study. The data collection included personal communication, process observation and an in-depth semi-structured interview. The findings were analyzed using a value stream mapping method. Findings and Discussion The data collection offered a holistic insight into the processes and motivation that are involved in the second-hand concept of the studied retailer. The findings concerning the reverse logistics were depicted in the current-state value stream map. This was adjusted to a possible future-state map based on improvements which were elaborated with the reviewed literature. Additionally, a recommendation for a performance measurement framework was developed. Research limitations The studied retail concept was still at its start-up stage at the time of the research. Therefore, only a limited amount of empirical data was available to collect. Furthermore, the research was conducted over a short period of time and the impact of the recommended improvements for the value stream could not be observed and evaluated. A future research is suggested to focus on the monitoring of the implementation of the future-state map. The success can be assessed with the help of the proposed performance measurement framework and based on that a new future-state map should be created to ensure continuous improvement.

The aim is to use Lean Administration metodology to improve custom clearance process steps that do not add value, but it is necessary to carry out them due to legislative reasons. The company has excellent results of applying the Lean principles in manufacturing and this thesis will bring to the company specific application of Lean Enterprise metodolgy outside manufacturing. The thesis is proof of the implementation of the company philosophy of continuous improvement, perfection does not exist, there is always the possibility of improvement.

Therefore, the purpose of this paper is to analyze, through a case study, the applicability of lean manufacturing, mainly the practical value stream mapping of the flow of value to measure sustainability, that is, to measure environmental losses, social losses and economic losses from the manufacturing process of a specific product (in this case a water-cooled cable manufacturing process). As a result of the research, it was possible to identify and quantify the economic, environmental and social losses at each stage of the manufacturing process, such as lead time, excess and loss of water, energy and raw materials, and potential risks health and safety of employees. / O chão-de-fábrica industrial é cada vez mais pressionado pelas partes interessadas (sociedade, clientes, governo, etc.) para a adoção da filosofia sustentável para a obtenção da redução do impacto ambiental, social e econômico nos processos de fabricação; e é a fase de fabricação que mais contribui, principalmente, para o impacto ambiental. Portanto, este trabalho tem como proposta analisar, através de um estudo de caso, a aplicabilidade da manufatura enxuta, principalmente da prática de mapeamento de fluxo de valor para medir a sustentabilidade, ou seja, medir as perdas ambientais, as perdas sociais e as perdas econômicas do processo de fabricação de um produto específico (no caso, um processo de fabricação de cabos refrigerados a água). Como resultado de pesquisa, foi possível identificar e quantificar as perdas econômicas, ambientais e sociais em cada etapa do processo de fabricação, como, por exemplo, o lead time, excesso e perda de água, de energia e de matéria-prima, e os riscos potenciais à saúde e segurança dos colaboradores.

The diploma thesis is concerned with the implementation of lean components in the production process of selected company. Through the Value Stream Mapping method an analysis of the current state is performed that resulted several shortcomings of the current production process. Based on the outcomes of the analysis, proposal of new production line is made that contributes to increased customer value within a shorter production time, reduce waste and thus to streamlining the production process.

The diploma thesis is focused on the implementation of lean production con-ditions into the production process of the selected company, analyze and find bottleneck. Aim of thesis is to eliminate the downtime of the production pro-cess to provide lean conditions for the selected section when introducing a new product and new facilities at the worplace. First part of thesis is devoted to literature review and dealingwith teheoteri-calpreparation, understanding principles and methods of lean production. Second part is dealing with analyzing production processes of product and in-dividual production operations, application of lean production methods and proposals for a new organization of the workplace.

This master's thesis is dealing value stream optimisation of finished goods in company Continental Automotive Systems, s. r. o. between production lines and expedition in terms of lean production methods and industrial engineering. The first part deals with theoretical training methodologies and understanding of lean manufacturing and industrial engineering. The second part analyzes the value stream of finished goods between production lines and expeditinon, identifying bottlenecks and design improvements.

The thesis is focused on the implementation of a lean component in the manufacturing process of First Brno Machinery Velká Bíteš, Ltd. With the help of lean componant Value Stream Mapping (VSM – value stream mapping) an analysis of the current status is determined that underlies the bottleneck analysis in the manufacturing process. Based on that analysis the optimal future state of the manufacturing process is designed which leads to a production efficiency. This thesis focuses on increasing customer value and reducing waste in manufacturing.

This master’s thesis concerns optimization of quotation process. It describes mapping of value stream by VSM Method (value stream mapping) in practical way in order to minimize cost. Further on it describes three points of view method when surveying and modifying process. It analyses process on three levels and describes suitable solution which makes process smoother and more effective. At the conclusion of this diploma project belongs evaluation of realised solutions and measures that need to be taken in future.

The aim of the diploma thesis “Value stream mapping” is to analyse the montage workplace of the company IFE-CR, a.s. with focus on the value stream and the methods of lean production. The thesis aims to identify priorities for applying lean production methods at the montage workplace and to propose concrete measures in order to reduce different types of wasting. The first part of the thesis is dealing with the theory, understanding the main principles and methods of lean production, as well as with the method of value stream mapping. The second part is dealing with value stream analysis of the montage workplace and proposes concrete measures to reduce wasting and to increase the production effectiveness, respectively to improve the material stream trough implementation of selected lean production methods in the montage workplace.

This diploma thesis: „Analysis of the value stream“ deals with the mapping of production processes in terms of flow value, their analysis and application of possible improvements that should be task to speed up and improve process. Finally, correctness will be proved with process audit of proposed solutions and will be quantified also possible savings.
