Ecological Systems and Devices Annotation << Back Logistik curve – order and chaos at natural systems Svetlosanov V.A., Kudin V.N., Kulikov A.N. The different variants of the processes, which are described by Verhulst equation, are considered. Generally logistic equation characterizes the order of natural systems. The chaos of natural systems is connected with the loss of stability. It may be realized for the first as the result of the influence of the small random perturbations (as white noise) for the second as the result of the variation of the logistic equation some parameters under numerical decision. Key words: mathematical mode; chaos; logistik equation; random perturbations. E-mail: vsvetlosanov@mail.ru
