The impact of standardisation method on smart city ranking

Sojda Adam, Wolny Maciej

Purpose: The main purpose of the work is to present the impact of standardisation methods on the ranking results. The second purpose of the article was to present Warsaw’s position in comparison with the capitals of countries from the Eurozone. Design/methodology/approach: Major European cities were assessed using Eurostat data. The proprietary Smart City Index (SCI) indicator is proposed for the study, referring to six areas of Smart City assessment. Two measures are indicated in each of them. The first is an objective measure, while the second is a subjective measure, based on the opinion of the city’s residents about the situation in the city, or their own situation. Building rankings of the cities, following normalisation methods were used and compared: unitisation, unitisation with zero minimum, normalisation in range [-1, 1], classical standardisation, Weber standardisation and two quotient methods. Findings: The best results were obtained for the classical standardisation. For this method we obtained the smallest number of consistent positions in rankings and the minimal maximum of distance between the positions in rankings. The position of Warsaw as a city in 16th position (20 of all) was confirmed regardless of the standardization method used. Originality/value: There is proposed an original method to assess cities based on Eurostat data. This method allows construction of Smart City ranking. The main value of the work is that the classical standardisation is recommended to transform the original values of individual indicators.

A method for determination and standardization of performance parameters for aircrafts with electric drives

Jakielaszek Z., Nowakowski M.

Journal of KONBiN

2014

No. 2 (30)

31--46

The study outlines the technique for flight tests carried out for a plane powered by an electric drive and the method for standardization of performance parameters applicable to evaluation of test results. Due to the relatively new type of drive, which is an electric motor, the literature references provide no descriptions of such issues. Therefore the solutions presented in the paper are the own contribution of the research team from Air Force Institute of Technology (ITWL).

W pracy przedstawiono technikę przeprowadzania prób w locie w odniesieniu do samolotów napędzanych silnikiem elektrycznym. Zaproponowano też metodę standaryzacji wyników badań. Ze względu na stosunkowo nowy rodzaj napędu - silnik elektryczny - brak jest w literaturze opisu podobnych zagadnień. Dlatego rozwiązania przedstawione w pracy stanowią autorską propozycję zespołu badawczego ITWL.
