A multiple criteria socio-technical approach for the Portuguese Army Special Forces recruitment.

Cat-SD (Categorization by Similarity-Dissimilarity) is a method developed for handling nominal classification problems in the context of Multiple Criteria Decision Aiding (MCDA). This paper describes the design and implementation of this method and an application dealing with a recruitment and selection process in the Special Forces of the Portuguese Army. Besides, it proposes interaction protocols to elicit the preference parameters of the method to facilitate the construction of a decision model when the analyst guides the decision maker. Cat-SD has been implemented in DecSpace, a user-friendly online platform for supporting decision aiding processes using one or more MCDA methods simultaneously. The study related to the Portuguese Army Special Forces recruitment and selection demonstrates how these protocols and a tool like DecSpace can facilitate the process of applying the method in real-world scenarios.
