The paper presents the possibility of fabricating ceramic-metal composites by an innovative method of centrifugal slip casting in the magnetic field. It was examined whether the use of this method would allow obtaining a gradient concentration of metal particles in the ceramic matrix. In the applied technique, the horizontal rotation axis was used. The study investigated the effect of solid phase content on the properties and microstructure of the products. Water-based suspensions with 35, 40, 45 and 50 vol.% of solid-phase content were prepared with 10 vol.% additional of nickel powder. The viscosity of prepared slurries was considered. The gradient distribution of nickel particles in the zirconia matrix was observed on SEM. Vickers hardness of ZrO2-Ni composites has been measured. The research revealed that the physical properties depend on the volume fraction of solid content and increase as the volume of solid content increases.

Background: SMEs performance and their innovativeness are associated to their participation in innovation networks. Thus, SMEs tend to join clusters aiming to accelerate their process of innovation, catch up with the dynamics of the industry and increase their probability to access external knowledge and resources. Consequently, promoting a collaborative atmosphere by boosting the synergies between cluster managers and SMEs will foment a culture of innovation. Moreover, the inclusion of new technologies, and especially the advent of industry 4.0, is facilitating collaboration, while at the same time accelerating the development of innovation outcomes and setting new challenges for SMEs. This contribution identifies discrepancies between offer (clusters) and demand (SMEs), hindering the creation of a culture of innovation and highlights critical points, where both SMEs and Clusters, may gain from a proper interaction. Methods: 120 empirical studies analyzing innovation determinants have been evaluated. Based on these determinants and stressing the importance of SMEs participating in collaborative-networked innovation actions, a concept for supporting the creation of a culture of innovation is proposed. This concept is enhanced by exploring potential benefits of industry 4.0 technologies supporting the acquisition, assimilation and transformation of knowledge into innovation. Additionally, in order to gain an insight about the interrelation between clusters and SMEs towards the creation of an innovation culture, an empirical study has been conducted. Results: The descriptive analysis shows that communication problems and discrepancies between cluster organizations and SMEs are evident. Moreover, the understanding of SMEs on the requirements for building an innovation culture is rather low. Although cluster organizations tend to generate services supporting their members' innovation processes, a gap between offer and demand is observable among all phases defined in the concept. Conclusions: we suggest that cluster managers could play a more preponderant role as orchestrators of innovation by adjusting their services to the requirements of each innovation process phase. Moreover, this work highlights inconsistencies between offer (clusters) and demand (SMEs) constraining the creation of a culture of innovation, particularly stressing communication problems. Hence, the integration of innovative communication channels, having the potential to increase the effectiveness of communication strategies between cluster managers and SMEs, are key for facilitating a culture of innovation in organizations, especially in SMEs. In this case, we suggest exploring different elements around the industry 4.0 in order to define the characteristics of such communication channels, particularly those supporting the acquisition, assimilation and transformation of internal and external knowledge into innovation.

Wstęp: Sposób działalność małych i średnich przedsiębiorstw (MSP) jak i ich innowacyjność jest związany z ich uczestnictwem w sieciach innowacji. Dlatego też MSP skłaniają się do dołączania się do klasterów, aby przyspieszyć swój proces innowacji, podążyć za dynamiką branży oraz zwiększyć prawdopodobieństwa swojego dostępu do zewnętrznych zasobów i wiedzy. W efekcie, promocja atmosfery współpracy poprzez wspieranie synergii między menadżerami klastru oraz MSP sprzyja tworzeniu kultury innowacyjności. Dodatkowo, rozprzestrzenianie się nowych technologii, szczególnie w obszarze Industry 4.0., sprzyja współpracy, przyspiesza rozwój innowacyjności oraz stwarza nowe wyzwania przez MSP. Jednak z drugiej strony takie postępowania ujawnia różnice pomiędzy ofertą (klastery) a popytem (MSP), mogące opóźnić tworzenie kultury innowacyjności oraz pokazuje punkty krytyczne, w których zarówno klastery jak i MSP mogłyby zyskać przy prawidłowemu współdziałaniu. Metody: Analizie i ocenie poddano 120 praktycznych przypadków dotyczących wyznaczników innowacyjności. W oparciu o ta analizę, zaproponowano koncepcję tworzenia kultury innowacyjności. Dodatkowo w celu lepszego wglądu w relacje tworzenie kultury innowacyjności między klasterami a MSP, przeprowadzono odpowiednie badania empiryczne. Wyniki: Analiza opisowa wykazało istotne problemy komunikacyjne i różnice pomiędzy organizacjami klasterowymi a MSP. Dodatkowo zrozumienie MSP odnośnie wymagań do budowy kultury innowacyjności jest raczej niskie. Chociaż organizacje klasterowe są ukierunkowane do dostarczania usług wspierających procesy innowacyjności ich członków, to jest zauważalna istotna różnica pomiędzy podażą i popytem w obrębie wszystkich faz zdefiniowanym w koncepcji. Wnioski: Menadżerowie klastru mogą odgrywać ważną rolę w kształtowaniu innowacyjności poprzez dostosowanie oferowanych usług do zapotrzebowania na każdym etapie procesu innowacyjności. Co więcej, zwrócono uwagę na niezgodność pomiędzy podażą (klastru) a popytem (MSP) ograniczającą tworzenie kultury innowacyjności, szczególnie podkreślając problemy komunikacyjne. W związku z tym integracja kanałów komunikacyjnych ma kluczowy wpływ na zwiększenie kultury innowacyjności szczególnie w obrębie MSP. Podkreślono konieczność dalszych badań poszczególnych elementów w obrębie Industry 4.0 w celu zdefiniowania cech charakterystycznych kanałów komunikacyjnych, w szczególności wspierających akwizycję, asymilację i transformację wewnętrznej i zewnętrznej wiedzy w innowację.

Due to the pressure of competition, high process efficiency has become a corporate ob¬jective for companies to maintain their global competitiveness. To ensure high process efficiency, it is important to constantly reduce process losses within various business activities. Different concepts to evaluate the efficiency of a company's key processes have therefore been discussed in academia. These concepts largely concentrate on the production area of one single company. Currently, howev¬er, not only individual companies but also entire supply chains are competing with each other. For this reason, it is necessary to thoroughly evaluate and increase the efficiency of production, transport, handling, and warehousing processes along the entire Supply Chain. We addressed this challenge with the conceptual design of a supply chain improvement system (SCIS). The results of empirical research focussing on the managerial purpose of the SCIS indicate that intercompany efficiency evaluation and improvement are prevalent issues in entrepreneurial practice.

Because of rapidly changing customer requirements, current company-focused measures to enhance flexibility at the supply chain level are not sufficient. Therefore, flexible supply chain performance is essential for firms aiming to fulfill service level agreements despite increasing complexity, shorter delivery times, and dynamic market demands. Therefore, we suggest imple-menting flexibility-enhancing measures within and between supply chain entities that address the particular supply chain type and its flexibility requirements. Towards this end, flexibility management must be considered as a holistic management approach. This paper presents conceptual framework that helps to identify company-internal flexibility drivers to support flexible supply chain per-formance.

This paper presents empirical results on the functional performance of freight villages as supply chain interfaces. Moreover, it provides an overview of the current state of research on how freight villages contribute to an enhancement of supply chain performance. Databank research was conducted to review internationally published literature and existing research was evaluated based on relevant international contributions. Furthermore, a questionnaire was constructed to carry out an explorative study of freight villages in Germany. The functional performance of the investigated freight villages showed that there is a strong need to attach greater importance to the fulfilment of functions targeting on the streamlining of logistical processes within supply chains and the integration of value-adding services at supply chain interfaces. Results from this study provide insight into the potential performance of freight villages as supply chain interfaces. Therefore it is necessary to put intelligent multimodal transport chains into practice and to provide powerful logistical and value-adding services to achieve greater flexibility of adjustment to changing demand and a higher delivery service level. This paper contributes to the state of research by identifying a gap between the functional performance postulated in literature and the practical performance of freight villages. Moreover, it provides implications for closing this gap to implement high-performing interfaces within the supply chain.

The goal of this work was to establish a pathway to the preparation of optical inactive layer on the surface of luminescent materials (Ba, Sr)2SiO4:Eu2+ to improve their stability. To solve this problem different coating routes and precursors were applied. Especially, it was expected that coating layer on the phosphor particles would provide the continuous and uniform coverage to improve the stability of the phosphors, without loss of luminescent properties.

Due to the fact that an efficient execution of production ramp-ups strongly impacts the economical success of a new product, ramp-up management shifted into the centre of scientific and practical interest in recent years. Despite great efforts, many important problems could not be solved so far. One of the unsolved problems concerns the planning and controlling of ramp-up costs. Up to now ramp-up costs are often insufficiently planned and controlled. Adequate methods and/or instruments are still missing. In this contribution we develop a key metric system to improve the planning of ramp-up costs by reducing complexity within the ramp-up planning process and increasing transparency. We demonstrate how this key metric system can be systematically built. Used consequently, this approach helps to increase the quality in planning ramp-up costs as well as the planning reliability.

Nowadays companies are forced to streamline their efforts to guarantee a high performance. In order to maintain this performance the whole supply chain (SC) has to respond quickly and cost effectively to disruptions/changes in the environment. Therefore, improvements of the flexibility of the entire supply chain are necessary. We call the flexibility of supply chains, supply chain flexibility (SCF). In this contribution we will present the basics SCF and provide a conceptual framework to assess the contribution of supply chain management (SCM) measures to SCF. Therefore, we define coherent parameters enabling an indication of SCF. Furthermore, exemplary measures and their effects on those parameters will be presented.
