Background and Study Aim: One of the most important topics for research revolves around the choice and selection of individuals for jobs that require exceptional morphofunctional abilities and my cause health impairments and even be life threatening. The study aims to design an algorithm for rating of security guards based on multi-criteria decision making methods and wisdom-of-crowds principle and use it to form a group of elite security guards.
Material and Methods: The research subject: 118 randomly selected security guards from the company G4S Lietuva. Twenty two leader managers (experts) from G4S Lietuvawith not less than 10 years experience of service at private security structures involving the execution and organisation of security solutions have rated the competences chosen by authors of the article.Selected security guards were tested and evaluated according to 41 criteria. The data received was classified into six groups of competences regarding the features analysed: theoretical and practical preparation; professional activity; mental qualities; physical development; motor abilities; and fighting efficiency. Staff selection method based on a single-expert evaluation and selection method based on wisdom-of-crowds principle, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Simple Additive Weighting (SWA) methods.
Results: The weights of criteria used for evaluation of security guards revealed the main selection and development tendencies. The following levels of criteria were defined: very important (theoretical and practical preparing; mental qualities; motor abilities), important (fighting efficiency) and moderately important (professional activity; physical development). Professional activities of security guards encompass observation, help and conflict resolution.
Conclusions: The staff selection algorithm recommended by authors of the article is more efficient by one-third in comparison to other currently used selection methods. Issues pertaining to contemporary selection and rating of security guards, just as any other staff of militarised structures, are considered to be especially relevant.
