Development of a polymodel complex of information systems resource management

The object of the study is information systems. The research addresses the problem of increasing the accuracy of modeling the functioning processes of information systems. A polymodel complex for resource management in information systems has been developed. The originality of the research is ensured by: – a comprehensive description of the functioning processes of various types of information systems through the development of corresponding mathematical expressions, which enhances the accuracy of modeling for subsequent managerial decision-making; – the inclusion of both static and dynamic processes occurring within information systems, using a hierarchical system of interconnected mathematical models; – the ability to model either an individual process within an information system or to perform integrated modeling of multiple processes using a single or a set of mathematical models; – a dynamic description of the process of controlling the trajectory of information systems during their operation through proposed analytical expressions, enabling forecasting of the system’s behavior N steps ahead; – modeling the process of operations management during computational 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 management tasks of information systems characterized by a high level of complexity
