Analysis of the simple WISP method results using different normalization procedures

Abstract

The standard WISP method uses the max normalization procedure. In order to check its robustness, the use of the WISP method with square root and sum normalization procedures is discussed in this article. In order to check the similarity of the obtained results, several analyzes were performed using the Python programming language, where the similarity of the obtained results was checked using the cosine similarity measure. The similarity was also checked concerning the results obtained using prominent MCDM methods. The achieved results confirm the significant similarity of the results obtained using the WISP method with the results obtained using the selected MCDM methods, even in the case of using square rot or sum normalization procedures.
