Nuova Mama Mia Bechicerecu Mic, of Timiş county, mentioning the existing possibility of its application within any other football or other collective sports club and why not even within economical entities, under the condition of a pertinent and realist appraisal of entry data in the suggested fuzzy algorithm.
