Besides, non-functional goals that have to be met by the system may be introduced, defining Quality-of-Service (QoS) requirements which drive the adaptation. This paper enhances a previous study which surveyed the literature with respect to performance-driven self-adaptation, supported by the Queuing Network paradigm. The seven approaches identified in previous work are detailed in this paper based on a well-defined taxonomy deriving from the former’s classification scheme and spanning over different dimensions, with particular emphasis on the way adaptation mechanisms are introduced, e.g. available knobs, nonfunctional goals, sources of uncertainty. Based on such taxonomy, internal characteristics of those approaches are described, as well as commonalities and differences, aimed at providing a detailed view of the current state-of-art in the context of performance-driven self-adaptation supported by the Queuing Network paradigm.","PeriodicalId":376249,"journal":{"name":"J.

It is shown that from the standpoint of the modern approach, complex technical control systems satisfy the definition of intelligent control systems as systems that act rationally and optimally. It is from these positions that the report considers the problems of increasing the intelligence of the TPP’ automated control system based on the creation of a unified system for improving the quality of control and solving optimization problems at all hierarchical levels of technological and production processes control. As an estimation of the level of intelligence, it is proposed to use a conditional \"intelligence coefficient\", the essence of which is to determine the share of intelligent technologies in the total volume of performed functions of the automated control system on the considered task or control function. A method for determining the intelligence coefficient at hierarchical levels of control and the automated control system as a whole is proposed. An illustrative example of calculating this coefficient at all hierarchical levels of control in relation to TPPs with CCGT (combine circle gas turbine)) PGU-450 is provided. It is shown that for a significant increase in the level of intelligence of the ACS based on PTC, special attention should be paid to the intellectualization of optimization problems at the block and station levels of control.","PeriodicalId":376249,"journal":{"name":"J.
