Applying the repertory grid method for technology forecasting: civil unmanned aviation systems for Germany

Eimecke J., Baumert K., Baier D.

Management and Production Engineering Review

2017

Vol. 8, No. 3

22--30

Multistage expert surveys like the Delphi method are proven concepts for technology forecasting that enable the prediction of content-related and temporal development in fields of innovation (e.g., [1, 2]). Advantages of these qualitative multistage methods are a simple and easy to understand concept while still delivering valid results [3]. Nevertheless, the literature also points out certain disadvantages especially in large-scale technology forecasts in particularly abstract fields of innovation [4]. The proposed approach highlights the usefulness of the repertory grid method as an alternative for technology forecasting and as a first step for preference measurement. The basic approach from Baier and Kohler [5] is modified in-so-far that an online survey reduces the cognitive burden for the experts and simplifies the data collection process. Advantages over alternative approaches through its simple structure and through combining qualitative and quantitative methods are shown and an adaption on an actual field of innovation – civil drones in Germany – is done. The measurement of a common terminology for all experts minimizes misunderstandings during the interview and the achievement of an inter-individual comparable level of abstraction is forced by the laddering technique [6] during the interview.

Namorit - nowy rodzaj bentonitu do klasycznych mas formierskich

Baier D., Schmidt F.

Przegląd Odlewnictwa

2004

Vol. 54, nr 6

497-505

W artykule przedstawiono wyniki badań nowego produktu. Badania te obejmują techniczną ocenę przydatności bentonitu dla odlewnictwa w zakresach zdolności pęcznienia i roztwarzania oraz odporności termicznej. Przytoczono także wyniki badań parametrów technologicznych mas formierskich z użyciem nowego bentonitu w odlewni +GF+ w Mettman zebrane za okres jednego roku oraz efekty prób produkcyjnych w tej odlewni. Podano także wyniki badań specjalnych dotyczących zdolności hydratacji i odporności masy formierskiej na tworzenie strupów. Namorit S stanowi rozszerzenie oferty Hüttenes-Albertus w zakresie dodatków do klasycznych mas formierskich.

In the article research results of a new product are presented. The research comprised the technical estimation of the bentonite usefulness for foundry industry in the scopes of growth and solubilazmg abilities as well as of the thermal resistance. There also are reported results of determination of the process parameter of moulding sands with using the new bentonite in the + GF+ foundry in Mettman, collected during one year, as well as results of the production tests in this foundry. Farther on the results of special investigations concerning hydratation ability and resistance of the moulding sand against the buckle formation are given. NAMORIT S enlarges the offer of Hüttenes-Albertus in the scope of additions for the classical moulding sands.
