    Industry 4.0, Vol. 7 (2022), Issue 4, pg(s) 151-154

    In the context of large-scale and diverse forms of international assistance for the post-war reconstruction of Ukraine, it is necessary to identify and offer foreign partners a format to support tourism in our country, especially inbound one. A possible proposal is to develop an international program to encourage foreign tourists to come to Ukraine on special tours, which will be partially funded by donor countries. Combining domestic tourist flows with foreign flows of this type is possible through tourist events, especially festivals. In this format, the festival will have significant synergetic potential, as it will be a point of unification of tourist flows in time and space. The experience of international kite festivals as a special form of event tourism is researched. It allowed to summarize certain features of festivals as tourist events. Certain aspects and features proved the complexity of such phenomena as a tourist event, festival event, the complexity of their preparation and conduct, active interaction with socio-economic processes in the territory.

    Industry 4.0, Vol. 6 (2021), Issue 3, pg(s) 102-105

    Additive manufacturing is an established production method to realize Direct Digital Manufacturing in Industry 4.0. Especially for metal components, production requires high investment sums and high levels of know-how in the organisation. To make the advantages of the technology accessible even without high initial investment costs, co-called online hubs became an external and decentralised alternative to additive in-house production. After uploading the geometry to the online portals, material and post processing can be selected. The hub gives the customer a direct pricing response which is one of the main economic indicators for a purchase decision. The present paper focuses on the influence of the order quantity and the complexity of the components on the price algorithm. Therefore, sample parts of varying complexity and sizes are developed and uploaded to analyse data. Based on the in-depth findings of the study, the results are discussed.
