The object of the study is the processes of functioning and maintenance, which together determine the stage of operation of a web-based information system for managing an enterprise or organization.
During the study, the problem of developing elements of the methodology for lifecycle management of a web-based information system was solved. Modern research in this area is mainly aimed at analyzing and developing individual aspects of managing the operation of complex systems. The main attention is paid to solving individual tasks of managing the operation of systems based on IoT or DevOps. General issues of creating and improving the System Lifecycle Management approach remain little studied.
During the study, the main provisions of the effective management concept of the life cycle of a web-based information system were proposed. This concept is based on a multi-level representation of the information system and the possibility of effective management of the system according to its properties. For further formal description of the proposed concept, the main concepts were defined and the ontology of this concept was developed. Based on this ontology, a generalized model of effective management of the operation of a web-based information system and a set of theoretical and categorical models that detail the description of the elements of this model were developed.
The resulting generalized model was taken as a basis for developing a formal problem statement of effective life cycle management of an operated information system as an IT service system. A formal description of the objective function and constraints of the problem of classical (permanent) life cycle management of an operated information system was proposed. On its basis, a formal description of the objective function and constraints of the problem of effective life cycle management of an operated web-based information system was proposed. It was determined that the problem of classical (permanent) life cycle management of an operated information system is a special case of the proposed problem of effective management.
The practical application of the obtained research results allows improving systems for life cycle management of an operated information system without global reengineering of existing systems and technologies for data storage and processing.
