Abstract: This bachelor thesis studies and analyzes the importance of business models in the Circular Economy. The company studied is an SME, i.e. 10 to 250 employees. The smaller companies are mainly confronted with the problem of resources, and the larger ones with their strategic orientation. The aim is to generate a guideline or way of doing that serves as a model for the SMEs already created so that the transition from the Linear Economy, which is still predominant today, to a Circular Economy. The idea is, after the study, a real case study of SMEs working with the premises of CE to establish a market model that follows the same. To support changes, we have documented the different business models currently in use, choosing the Canvas Business Model for several reasons and making the various changes necessary to make this a sustainable and circular model. In addition, it is established that the process of innovation and modification must be applied as a continuous cyclical process. If the company wants to be successful, it is a continuous cycle model, which should never stop.
Keywords: Business Models for Circular Economy, Business Model Canvas, Industrial symbiosis, Ressource efficciency, Synergies, Sustainable development, CE in SMEs, Circular Economy, Product Sustainable Design.

Abstract: The result of our research is a developed and implemented set of activities for new process or product development (NPD procedure) for SMEs environment in the plastic processing industry, which enables the production of products and services with a high value added. The developed NPD procedure consists of five consecutive and overlapping steps: attracting orders, designing a project, developing a product, developing a process and zero production series. Each distinct step is further divided into sub-activities supported by adequate methods and managed in an information system. Investigated and included were three different methodologies use for NPD procedure in the automotive industry such as Advanced Product Quality Planning (APQP), Design for Six Sigma (DFSS) and Stage/Gate methodology. The results presented in the paper show that the developed NPD procedure significantly improved NPD in terms of cost management and time-effectiveness.

Abstract: This paper studies the compliance of the fixture-workpiece system. Workpiece clamping case with two types of clamping elements is considered. The first type of clamping element is standard, with flat top, while the second one is specially designed, with round cutting insert. Analyzed was the case of workpiece clamping using small forces, whereby the deformations in the workpiece/clamping element interface are predominantly on the order of magnitude of roughness height. A comparative analysis of dynamic behaviour of both types of clamping elements is also presented. In comparison with its standard counterpart, the specially designed clamping element with round cutting insert has superior clamping performance regarding both tangential load capacity and compliance.
Keywords: clamping, clamping element design, product development, machining, cutting, compliance, fixture, roughness, analysis, dinamical behaviour

Abstract: Product design engineering is a complex discipline, which is undergoing a transformation from informal and largely experience-based domain to scientific oriented domain. Computational intelligence can contribute greatly to product design process, as it is becoming more and more evident that adding intelligence to existing computer aids, such as computer aided design systems, can lead to significant improvements in terms of effectiveness and reliability of various tasks within product design engineering. Providing computer aided decision support is one of the computational intelligence methods that proved to be effective in enabling more intelligent and less experience-dependent design performance. In this paper, some of the most crucial areas of product design engineering process that require additional computational intelligence in terms of computer aided decision support are presented together with some examples of intelligent knowledge-based modules applied to this areas.
Keywords: product development, design engineering, design for X, computational intelligence, decision support, knowledge-based modules

Abstract: In general, computer tools for ergonomic CAD do not assist designer with higher level advice when performing ergonomic design. Designer has to possess expert knowledge and experience in many fields of engineering design including ergonomics in order to deliver successful designs. Such multi-levelexperts are rare and usually occupied. Two alternative ways are used to substitute these experts: teams of experts covering different areas of knowledge are established or some intelligent computer programs with expert knowledge are applied. In the second case, expert knowledge has to be collected, organized and encoded into the knowledge base of the system. An intelligent decision support system has been developed in order to overcome this bottleneck. This paper presents a knowledge base, containing ergonomic design knowledge specific for hand tools design. A pneumatic hammer handle design is used as a case study to show how ergonomic design knowledge built in the system is used to improve the ergonomic value of the product.
