Problem setting. The development of the information theory conflicts is connected with the need to form new models that take into account new factors and features of real actions of conflicting parties in the information area. Currently, a fairly developed scientific and methodological apparatus for study of information conflict are models in the formalism of the Markov theory processes and game theory. At the same time, models based on dynamic systems are not sufficiently developed, and dynamic models of multilateral conflicts are not available in well-known publications.Target. The purpose of the work is to form a dynamic plurilateral information conflict model with different participant strategies.Results. The research results in a dynamic plurilateral information conflict model with different participant strategies. The elements of the model scientific novelty are: the conflict formalization in the form of differential equations system, which are based on the original modification of the Lotki-Voltera model equations; nine strategies for action by parties to a multilateral conflict with varying degrees of conflict; each strategy formalization in the form of coefficients or complex functions with the modeling possibility of their application and change in duel conflicts between each pair of sides.Practical significance. The model presented using in the article allows: to study the dynamic of changes in the conflict parties resources; identify local wins and losses in transition mode; to make conclusions about global wins and losses of the parties over the conflict duration; to make recommendations about party-specific strategies choice and parameters of their strategies usefulness for achieving global wins. These studies may be useful to those skilled special purpose information systems field, electronic warfare or information warfare.
