Information-resource and cognitive concept of threat’s influence identification on technogenic system based on the cause and category diagrams integration

Abstract

The system analysis of the aggregate structure of the energy-active object is carried out in the article, adding multilevel complexity of system description. The complexity of the functioning tasks, mode management are substantiated. An important task is to solve the problem of identifying the risks level and crises causes as well as emergencies by operational personal of ACS-TP. The problem and its solution requires a certain level of adequate thinking, which would allow the operator to imagine the scheme of all object units interaction from input to output, physical and energy transformations during technological process in his point of view, as well as the ability to assess the content of the situation and to form the basis of decisionmaking. The concepts of the image are substantiated and the information image, situations and the influence cause-effect diagram of control actions and disturbance factors on an object mode functioning of technogenic system are formed. The basic models of systems description are considered, which are based on the description concepts and connections reflection between objects and components: structural analysis; theoretical-multiple representations; categorically-function models. In these models, the basic are the sets of components and the relationship between them, which reflect the system organization as a whole, which must be perceived by the operator while management tasks performance of the aggregate object according to the target task as in logical-graph and algebraic representation but also in block representation. Structural images in the conceptual basis are formed, which highlights the most significant aspects of the structure and functioning of the object, parameters, characteristics, connections, resource factors areas of influence, actions on the design of units, which must be mastered and reflected in the field of attention and memory (operational, deep) cognitive system of the operator with appropriate training and knowledge base necessary to perform control actions in the operational management of energy-intensive object in the structure of a thermal power plant, which is a component of technogenic and ecological systems.
