The research addresses the problem of increasing the accu¬racy of modeling the functioning pro¬cesses of information systems. A poly-model complex for resource manage¬ment in information systems has been developed. The originality of the research is ensured by: – a comprehensive description of the functioning processes of vari¬ous types of information systems through the development of corre¬sponding mathematical expressions, which enhances the accuracy of mod¬eling for subsequent managerial deci¬sion-making; – the inclusion of both static and dynamic processes occurring within information systems, using a hierar¬chical system of interconnected mathe-matical models; – the ability to model either an indi¬vidual process within an information system or to perform integrated model¬ing of multiple processes using a single or a set of mathematical models; – a dynamic description of the process of controlling the trajecto¬ry of information systems during their operation through proposed analytical expressions, enabling forecasting of the system’s behavior N steps ahead; – modeling the process of opera¬tions management during computa¬tional tasks within the functioning of information systems, which allows for planning of optimal load distribution on the hardware components; – simulation of the dynamics of resource management in information systems during their operation, making it possible to forecast the engagement of resources throughout their lifecycle. The proposed polymodel complex is advisable to use for solving man-agement tasks of information systems characterized by a high level of com¬plexity.enartificial intelligencedestabilizing factorsoperational lev¬elsindicatorscriteriaefficiencyreli¬abilityArticle
