Therefore, we designed a concept with two dimensions: on one hand a technical infrastructure facing Industry 4.0, on the other hand a management approach describing involved roles and relevant day-to-day activities.

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.}, language = {en} } @misc{HermannWinklerTinello, author = {Hermann, Mandy and Winkler, Herwig and Tinello, Daniel}, title = {Elaboration and analysis of key figure-based approaches for the efficiency assessment of traditional and bio-inspired factory layouts}, series = {Procedia CIRP}, volume = {72}, journal = {Procedia CIRP}, doi = {10.1016/j.procir.2018.03.052}, pages = {732 -- 738}, abstract = {Most factory layouts based on stable markets.

However, even after more than 10 years of the technology's existence, it is barely used for any self-sustaining applications. This raises the question of why BC cannot prevail against its alternatives. With this paper we want to identify criteria by which the added value of BCT can be measured. Furthermore, we want to evaluate how well the different supply chains (SC) exploit the added values of BCT. Methods: For this, we identified real-world examples and case studies for luxury, food, and healthcare SCs. These examples are described in detail and then analyzed for their added value compared to possible alternatives. Results: The results show that in the clusters of food and healthcare SCs, no general added value of BC over current best-practice solutions could be verified. Luxury SCs manage valuable products that are typically traded in small quantities. It is within this cluster that the implementation of BC can be justified best. Conclusions: In conclusion, this study shows that the application of BCT is especially beneficial for goods with a high value and low trade volume. In addition, the interface between reality and the digital twin should be as secure as the database or BC solution itself. Furthermore, the demand for transparency and immutability of data should be more important than the need to protect sensitive data. Finally, SC participants, especially the end customer, must also be able to appreciate the advantages of BCT.}, language = {en} } @misc{KuteyiWinkler, author = {Kuteyi, Damilola and Winkler, Herwig}, title = {Logistics Challenges in Sub-Saharan Africa and Opportunities for Digitalization}, series = {Sustainability}, volume = {14}, journal = {Sustainability}, number = {4}, issn = {2071-1050}, doi = {10.3390/su14042399}, pages = {18}, abstract = {Improvements in logistics performance are considered to be a significant driver of economic growth.

However, these PLMs face certain challenges in managing the complex and decentralized product lifecycles. Methods: To this aim, this work investigates the currently implemented PLMs used in industries through the exploration of various software reviews and selection websites. Accordingly, these existing PLMs are quantitatively compared and analyzed. Results: The analysis shows that most of the existing PLMs do not contain all the required features; therefore, industries integrate different software to create a full-fledged PLM system. However, this practice results in reducing the overall system efficiency. In this context, this paper assesses and recommends a blockchain-based innovative solution that overcomes the challenges of existing PLMs, hence increasing the overall system efficiency. Furthermore, this work argues, in a logical way, that the recommended blockchain-based platform provides a secure and connected infrastructure for data handling, processing, and storage at different stages of the product lifecycle.

Consequently, a number of blockchain-based platforms are available today that offer vast applications across multiple sectors and industries. Implementing these blockchain-based platforms as an alternative to traditional product lifecycle management systems (PLMs) is one of the applications. However, before any platform is adopted, its nature, functionalities, and adaptability need to be clearly defined, evaluated, and verified. In this context, the proposed work explores the available blockchain-based platforms that can be used for the purpose of product lifecycle management. We then apply one of the multi-criteria decision-making techniques, i.e., the analytic hierarchy process (AHP), to select the best possible blockchain-based platform for PLM. As transaction speed, data privacy, and scalability are our prime concerns in PLM, we only considered the permissioned (private) blockchain platforms as available alternatives in the final selection process. Results achieved on the basis of considered criteria show that Hyperledger Fabric is the top-ranked among available alternatives to be used for PLM. Furthermore, as blockchain is a new technology, a clear comparison of the available platforms based on the performancebased metrics and key performance indicators is not completely matured and is still in the development stage.
