The analysis of the mechanism of collective behaviour based on fuzzy logic

In this paper an elementary mechanism of collective behaviour has been examined. This collective is considered as number of persons. Each member of the group makes a certain decisionbased on his own relation and the relations of other members. For instance, whether to engage incertain activity, whether to join to public organisation, whether to participate in the arrangements,to vote affirmatively etc. These cases can be united into one: the person should decide whetherto go into certain state. Personal opinion of each member of the group and opinions of othermembers according to the problem can be inaccurate or fuzzy. In this paper this fuzziness isconsidered according the theory of fuzzy sets and modeling. The behaviour of several types ofcollectives is researched.
