With the promotion of the 2030 sustainable development goals, more and moreEuropean countries started to highlight them in society, many European people alsoshowed that they are willing to purchase sustainable products, but theenvironmentally conscious consumers rarely translate “green” concerns andintentions into actual purchase behavior. This project is aimed to provide consumerswith comprehensive information about the products and find out the solution toencourage choosing sustainable products while purchasing home appliances. Nowadays home appliances are becoming a core area of consumption in bothdeveloped and developing countries, and it is one of the relevant areas ofintervention to ensure sustainable production (Hischier et al, 2020). Consumersbehavior has a big influence on the production, consumption and sustainability ofhome appliances, therefore it has been considered as the core studying field in thisproject. In order to have a better understanding of peoples current attitude towardssustainability and home appliances, an online survey was carried out with theconsideration of the purpose of this study and Theory of planned behavior (TPB)model. Then, by analysis of the customer journey map (CJM), the author found thepart with the most touchpoints, “information”. After brainstorming and benchmarking,a service design that focuses on Web User interface (UI) design wasproposed as the final proposal.

The aim of this master's thesis is to develop a simulation system using the Siemens sX traffic controllers configurations. The system is composed of two separate applications. The first one uses the existing platform SUMO as a source of simulation data and is also used as a server. The second is a web-based application for creating and editing simulation situations and also for visualisation of simulation data from the server. The introduction to the topic of traffic engineering and the dynamic traffic control is discussed first. The description of the design and implementation of the simulation application directly follows. In the next part the design and implementation of the web-based application  is discussed. The last part of the thesis describes the testing of the whole system.
