Efficiency of the Machining Process of Circular Shapes by Electrical Discharge Technology
53-61Megtekintések száma:115Due to its high machining precision, EDM technology is nowadays very important in the production of high-precision parts for various industries. The high precision of the machined surface in combination with the ability to machine circular surfaces brings, in addition to several advantages, some negatives. The most significant negative of this machining technology is the relatively low productivity as well as the overall production efficiency. The latter is affected by many accompanying phenomena. The main accompanying phenomenon that contributes to the decline in the overall economic efficiency of EDM is the microgeometry errors that occur due to the non-homogeneity of the EDM process. Another accompanying negative phenomenon is the geometric accuracy errors of the machined surface, as a consequence of systematic destruction of the wire tool electrode, faulty interpolation in its guidance, and, last but not least, its vibration. These aspects consequently lead to the requirement for multiple applications of additional finishing cuts, which significantly reduces the overall economic efficiency of the machining process. Therefore, the experimental research aimed to search for options that can effectively help to achieve higher productivity but especially the overall economic efficiency of the machining process.

Evaluating the Entrepreneurial Performance in South America. Case of Chile
13-28Megtekintések száma:131The research objective is to explore Chile's entrepreneurial landscape by assessing individual characteristics and institutional factors through a 'pillars' framework and compare it against Colombia, and Brazil; to identify socio-economic, individual, and institutional differences using the Global Entrepreneurship Index (GEI); to apply bottleneck approach to highlight areas requiring policy intervention. GEI features individual and institutional stage variables in a method where every variable collaboratively interacts, incorporating 14 foundational elements and three sub-indexes: attitudes, abilities, and aspirations. Ranking 18th on the GEI globally and the best in Latin America, Chile excels in key entrepreneurial pillars, showcasing strengths in innovation and a robust entrepreneurial culture. Brazil closely rivals Chile in competition and networking, emphasizing political and economic influence. Colombia surpasses Chile in internationalization and growth-stimulating policies but faces challenges like historical conflicts and wealth distribution. This study identified areas where immediate policy intervention may be necessary by examining Chiles's entrepreneurial ecosystem. The Penalty for Bottleneck (PFB) technique identified the weakest pillars highlighting process innovation, competition, and internationalization. The primary component identified as a bottleneck for resource allocation is Process Innovation, accounting for 73% of the allocation, followed by Competition at 23%. The findings show that allocating more resources to process innovation may improve greatly the overall GEI score.

Applying New Innovative Market Research Methods in the Innovation Process of New Products
56-69Megtekintések száma:243The innovation environment has changed a lot in the recent years, companies and their enterprises concentrating on product- and process innovation have undergone a lot of changes. According to GUPTA et al. (1986) product innovation is a multidisciplinary process. Although, all functional interfaces are important in the product development process, the research and development – marketing interface is one of the most difficult one. In the last two decades the incredibly fast penetration of the internet has more and more effects on the consumer attitudes. It encourages market researchers to apply such methods by which they could get as close as to the consumers to know their attitudes without taking them out of their natural habitat. In this study our aim is to concentrate on the first phase of the product innovation, which is the exploration of insights and attitudes. In this phase we can use the classical, conventional market research techniques if we want to get primary data, such as focus group interviews, questionnaires, in-depth interviews, but there are new methods as well. One of such novel methods is netnography. The biggest advantage of this research method is that the researcher can observe the consumer groups’ state of mind and decision-making mechanisms through publicly available communication sources in their natural environment. In this study it will be analysed how the directions of netnographic researches have changed by the dynamic changes of the internet. Besides, online participants’ attitudes towards healthconscious nutrition are analysed in practice. As a result of this study, special groups could be identified, which can provide a new perspective for the companies operating in this field beside the classical segmentation techniques. These groups can be the ones which draw up latent market requirements, and thus, helping the companies’ innovation processes.

Digitalizáció hatása a hazai kereskedelmi stratégiákra
318-333Megtekintések száma:1452Tanulmányunk célja, hogy feltérképezzük a digitális tér illeszkedését napjaink és a jövő kereskedelmébe és meghatározzuk a digitalizáció hatását a hazai kereskedelmi stratégiákra. A fogyasztók információszerzési és vásárlási szokásai drámaian megváltoztak. A ma fogyasztója számára elsősorban a kényelem, a hatékonyság (a termékhez való gyors, kényelmes hozzáférés a megfelelő ár-érték arányban) és az élmény jelentik azokat a kulcstényezőket, melyek alapján döntését meghozza. A kereskedők igazodva ezekhez újszerű kereskedelmi stratégiákat alakítottak ki, melyeknek szerves része a digitalizáció vívmányainak felhasználása. Ennek egyik vetülete az e-kereskedelem egyre erőteljesebb globális fejlődése. A hazai online kereskedelem is évről évre jelentősen bővül. 2018. évi adatok alapján a belföldi és külföldi online értékesítés volumene meghaladta az 1000 milliárd forintot. A hazai online fogyasztók egyre gyakrabban és egyre nagyobb értékben vásárolnak az interneten. Az online bevásárlás virtuális valóság platformokon való megvalósulása pedig élményszerűbbé teheti ezt a vásárlási módot. A webshopoknak újabb fogyasztói igényeknek kell megfelelni és a megrendelt árut mielőbb, lehetőleg 24 órán belül kiszállítani. A csomagok kézbesítésének számos változata kezd egyre népszerűbbé válni (pl. csomagautomaták, pick pack pontok). A hagyományos csatornákat sem szabad azonban eltemetni. Óriási előnyük, hogy a vásárló több érzékszerven keresztül válogathat a termékek között és az impulzusvásárlásnak is nagyobb teret enged. Ezt a kor követelményeinek megfelelő digitális technológiával kombinálva teljes körű vásárlási élmény nyújtható. Felismerve ezt az igényt az online és hagyományos csatornák manapság sok esetben már keverednek (pl. multichannel, omnichannel, crosschannel) és rengeteg lehetőséget nyújtanak a fogyasztóknak a vásárlási folyamat során. A vásárlók kényelmét szolgálja a hagyományos üzletek eladóterének optimalizálása és a vásárlói útvonalak digitális technológiákkal (pl. digitális polccímke) való támogatása is. Az újabb innovációk a vásárlási folyamat automatizációját vonják maguk után és szenzorok (pl. Amazon Go) vagy robotok (pl. Pepper) segítségével teszik kényelmesebbé és személyre szabottabbá a vásárlási folyamatot. A digitális személyi asszisztensek az eladószemélyzet digitális változataként fognak feltűnni a jövőbeli vásárlásaink során.
