Penkovskaya Study of structure of marine specialist activity in an ergative system on monitoring and managing automatic control parameters of safe navigation process The study of structures' common features and dynamics of the technical object tuning circuit performing automatic adjustment of safe navigation options has been conducted for the first time in the theory of ergative systems. The research of the structure and process of ergative system functioning including an automatic control system with the option of safe navigation conditions has been fulfilled. The function of signals' selection performing optimal control law reconfiguration of the mentioned system has been given, and some sequence of marine specialist activities allowing solve the problem of navigation safety has been composed. The ergative system retargeted by the ship specialist has a two-tier hierarchy. The first level is an automatic control of the safe navigation parameter, and the second is the level of reconfiguration where the ship specialist changes the parameters of regulation act. The two-level hierarchical representation of the ergative navigation security settings management system makes it possible to introduce the concept of reconfiguration of regulation level as ship specialist activity which is to reduce the uncertainty in the environment in the operation of this layer. Such a reduction can be achieved as a result of exposure to the upper level associated with ideas of the ship specialist on the regulation of safe navigation parameters of the vessel on the lower level – the level of direct control automatic safe navigation option. As a result of studying the activities of the ship specialist in the ergative system on monitoring and managing automatic control parameters of safe navigation process it has been found that the main task of the ship specialist in the operation within the ergative system ensuring the navigation safety is to monitor the input and output of the automatic control system, decisions on the choice of reconfiguration laws regulating signal on the basis of information about deviations and the implementation of these decisions. Key words: ergative system, automatic control system, marine specialist, regulation law, navigation safety.
